MAX6920AWP+T - Maxim Integrated Products, Inc.

General Description

The MAX6920 is a 12-output, 76V, vacuum fluorescent

display (VFD) tube driver that interfaces a multiplexed

VFD tube to a VFD controller such as the

MAX6850–MAX6853 or to a microcontroller. The

MAX6920 is also ideal for driving either static VFD tubes

or telecom relays.

Data is inputted using an industry-standard 4-wire serial

interface (CLOCK, DATA, LOAD, BLANK) for compatibili-

ty with both industry-standard drivers and Maxim’s VFD

controllers.

For easy display control, the active-high BLANK input

forces all driver outputs low, turning the display off, and

automatically puts the MAX6920 into shutdown mode.

Display intensity may also be controlled by pulse-width

modulating the BLANK input.

The MAX6920 has a serial interface data output pin,

DOUT, allowing any number of devices to be cascaded

on the same serial interface.

The MAX6920 is available in a 20-pin SO package.

Maxim also offers VFD drivers with either 20

(MAX6921/MAX6931) or 32 outputs (MAX6922 and

MAX6932).

Detailed Description

The MAX6920 is a VFD tube driver comprising a 4-wire

serial interface driving 12 high-voltage Rail-to-Rail®

output ports. The driver is suitable for both static and

multiplexed displays.

The output ports feature high current-sourcing capabili-

ty to drive current into grids and anodes of static or

multiplex VFDs. The ports also have active current sink-

ing for fast discharge of capacitive display electrodes

in multiplexing applications.

The 4-wire serial interface comprises a 12-bit shift reg-

ister and a 12-bit transparent latch. The shift register is

written through a clock input CLK and a data input DIN

and the data propagates to a data output DOUT. The

data output allows multiple drivers to be cascaded and

operated together. The output latch is transparent to

the shift register outputs when LOAD is high, and latch-

es the current state on the falling edge of LOAD.

Each driver output is a slew-rated controlled CMOS

push-pull switch driving between VBB and GND. The

output rise time is always slower than the output fall

time to avoid shoot-through currents during output tran-

sitions. The output slew rates are slow enough to mini-

mize EMI, yet are fast enough so as not to impact the

typical 100µs digit multiplex period and affect the dis-

play intensity.

Initial Power-Up and Operation

An internal reset circuit clears the internal registers of

the MAX6920 on power-up. All outputs OUT0 to OUT11

and the interface output DOUT initialize low regardless

of the initial logic levels of the CLK, DIN, BLANK, and

LOAD inputs.

4-Wire Serial Interface

The MAX6920 uses a 4-wire serial interface with three

inputs (DIN, CLK, LOAD) and a data output (DOUT).

This interface is used to write output data to the

MAX6920 (Figure 3) (Table 1). The serial interface data

word length is 12 bits, D0–D11.

The functions of the four serial interface pins are:

•CLK input is the interface clock, which shifts data

into the MAX6920’s 12-bit shift register on its rising

edge.

•LOAD input passes data from the MAX6920’s 12-

bit shift register to the 12-bit output latch when

LOAD is high (transparent latch), and latches the

data on LOAD’s falling edge.

•DIN is the interface data input, and must be stable

when it is sampled on the rising edge of CLK.

•DOUT is the interface data output, which shifts

data out from the MAX6920’s 12-bit shift register

on the falling edge of CLK. Data at DIN is propa-

gated through the shift register and appears at

DOUT (20 CLK cycles + tDO) later.

A fifth input pin, BLANK, can be taken high to force out-

puts OUT0 to OUT11 low, without altering the contents

of the output latches. When the BLANK input is low,

outputs OUT0 to OUT11 follow the state of the output

latches. A common use of the BLANK input is PWM

intensity control.

The BLANK input’s function is independent of the oper-

ation of the serial interface. Data can be shifted into the

serial interface shift register and latched regardless of

the state of BLANK.

Writing Device Registers Using the 4-Wire

Serial Interface

The MAX6920 is written using the following sequence:

1) Take CLK low.

2) Clock 12 bits of data in order D11 first to D0 last

into DIN, observing the data setup and hold times.

3) Load the 12 output latches with a falling edge

on LOAD.

LOAD may be high or low during a transmission. If

LOAD is high, then the data shifted into the shift regis-

ter at DIN appears at the OUT0 to OUT11 outputs.

CLK and DIN may be used to transmit data to other

peripherals. Activity on CLK always shifts data into the

MAX6920’s shift register. However, the MAX6920 only

updates its output latch on the rising edge of LOAD,

and the last 12 bits of data are loaded. Therefore, multi-

ple devices can share CLK and DIN as long as they

have unique LOAD controls.

Determining Driver Output Voltage Drop

The outputs are CMOS drivers, and have a resistive

characteristic. The typical and maximum sink and

source output resistances can be calculated from the

VHand VLelectrical characteristics. Use this calculated

resistance to determine the output voltage drop at dif-

ferent output currents.

Output Current Ratings

The continuous current source capability is 40mA per

output. Outputs may drive up to 75mA as a repetitive

peak current, subject to the on time (output high) being

no longer than 1ms, and the duty cycle being such that

the output power dissipation is no more than the dissipa-

tion for the continuous case. The repetitive peak rating

allows outputs to drive a higher current in multiplex grid

driver applications, where only one grid is on at a time,

and the multiplex time per grid is no more than 1ms.

8 _______________________________________________________________________________________

Since dissipation is proportional to current squared, the

maximum current that can be delivered for a given mul-

tiplex ratio is given by:

IPEAK = (grids x 1600)1/2mA

where grids is the number of grids in a multiplexed display.

This means that a duplex application (two grids) can use

a repetitive peak current of 56.5mA, a triplex application

(three grids) can use a repetitive peak current of 69.2mA,

and higher multiplex ratios are limited to 75mA.

Paralleling Outputs

Any number of outputs within the same package may

be paralleled in order to raise the current drive or

reduce the output resistance. Only parallel outputs

directly (by shorting outputs together) if the interface

control can be guaranteed to set the outputs to the

same level. Although the sink output is relatively weak

(typically 750Ω), that resistance is low enough to dissi-

pate 530mW when shorted to an opposite level output

at a VBB voltage of only 20V. A safe way to parallel out-

puts is to use diodes to prevent the outputs from sink-

ing current (Figure 4). Because the outputs cannot sink

current from the VFD tube, an external discharge resis-

tor, R, is required. For static tubes, R can be a large

value such as 100kΩ. For multiplexed tubes, the value

of the resistor can be determined by the load capaci-

tance and timing characteristics required. Resistor Rl

discharges tube capacitance C to 10% of the initial

voltage in 2.3 x RC seconds. So, for example, a 15kΩ

value for R discharges 100pF tube grid or anode from

40V to 4V in 3.5µs, but draws an additional 2.7mA from

the driver when either output is high.

Power Dissipation

Take care to ensure that the maximum package dissi-

pation ratings for the chosen package are not exceed-

ed. Over dissipation is unlikely to be an issue when

driving static tubes, but the peak currents are usually

higher for multiplexed tubes. When using multiple dri-

ver devices, try to share the average dissipation evenly

between the drivers.

Determine the power dissipation (PD) for the MAX6920

for static tube drivers with the following equation:

PD= (VCC x ICC) + (VBB x IBB) + ((VBB - VH) x

IANODE x A))

where:

A = number of anodes driven (a MAX6920 can drive a

maximum of 12).

IANODE = maximum anode current.

(VBB - VH) is the output voltage drop at the given maxi-

mum anode current IOUT.

A static tube dissipation example follows:

VCC = 5V ±5%, VBB = 10V to 18V, A = 12, IOUT = 2mA

PD= (5.25V x 0.7mA) + (18V x 0.9mA) + ((2.5V x

2mA/25mA) x 2mA x 12) = 24.7mW

Determine the power dissipation (PD) for the MAX6920

for multiplex tube drivers with the following equation:

PD= (VCC x ICC) + (VBB x IBB) + ((VBB - VH) x IANODE

x A) + ((VBB - VH) x IGRID))

where:

A = number of anodes driven

G = number of grids driven

IANODE = maximum anode current

IGRID = maximum grid current

The calculation presumes all anodes are on but only

one grid is on. The calculated PDis the worst case,

presuming one digit is always being driven with all its

anodes lit. Actual PDcan be estimated by multiplying

this PDfigure by the actual tube drive duty cycle, taking

into account interdigit blanking and any PWM intensity

control.

A multiplexed tube dissipation example follows:

VCC = 5V ±5%, VBB = 36V to 42V, A = 6, G = 6,

IANODE = 0.4mA, IGRID = 24mA

PD= (5.25V X 0.7mA)+ (42V x 0.9mA) + ((2.5V x

0.4mA/25mA) x 0.4mA x 6) +

((2.5V x 24mA/25mA) x 24mA) = 99mW

Thus, for a 20-pin wide SO package (TJA = 1 / 0.01 =

+100°C/W from Absolute Maximum Ratings), the maxi-

mum allowed ambient temperature TAis given by:

TJ(MAX) = TA+ (PDx TJA) = +150°C = TA+ (0.099 x

+100°C/W)

So TA= +140°C.

This means that the driver can be operated in this

application up to the MAX6920’s +125°C maximum

operating temperature.

Power-Supply Considerations

The MAX6920 operates with multiple power-supply volt-

ages. Bypass the VCC and VBB power-supply pins to

GND with a 0.1µF capacitor close to the device. For

multiplex applications, it may be necessary to add an

additional 1µF bulk electrolytic capacitor, or greater, to

the VBB supply.

Power-Supply Sequencing

The order of the power-supply sequencing is not impor-

tant. The MAX6920 will not be damaged if either VCC or

VBB is grounded (or maintained at any other voltage

below the data sheet minimum), while the other supply

is maintained up to its maximum rating. However, as

with any CMOS device, do not drive the MAX6920’s

logic inputs if the logic supply VCC is not operational

because the input protection diodes clamp the signals.
