Power Voltage Monitoring IC

with Watchdog Timer

MB3793-37A

■DESCRIPTION

The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer.

A reset signal is output when the power is cut or f alls abruptly. When the power recov ers normally after resetting,

a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for

system operation diagnosis can provide a fall-safe function for various application systems.

There is also a mask option that can detect voltages of 4.9 to 2.4 V in 0.1-V steps.

The model number is MB3793-37A corresponding to the detected voltage. The model number and package code

are as shown below.

■FEATURES

• Precise detection of power voltage fall: ±2.5%

• Detection voltage with hysteresis

• Low power dispersion: ICC = 30 µA (reference)

• Internal dual-input watchdog timer

• Watchdog-timer halt function (by inhibition pin)

• Independently-set wacthdog and reset times

• Two types of packages (SOP-8p in : 2 types)

■BLOCK DESCRIPTION

1. Comp. S

Comp. S is a comparator with hysteresis to compare the reference voltage with a voltage (VS) that is the result of

dividing the power vo lta ge (V CC) by resistors 1 and 2. When VS falls below 1.24 V, a reset signal is output.

This function enables the MB3793 to detect an abnomality within 1 µs when the power is cut or falls abruptly.

2. Output circuit

The output circuit contains a RESET output control comparator that compares the voltage at the CTP pin to the

thresh old volt age to rel ease the RESET output if the CTP pin voltage exceeds the threshold value.

Since the reset (RESET) output buffer has CMOS organization, no pull-up resistor is needed.

3. Pulse generator

The pulse generator generates pulses when the voltage at the CK1 and CK2 clock pins changes to High from Low

level (positive-edge trigger) and exceeds the threshold voltage; it sends the clock signal to the watchdog timer.

4. Watchdog timer

The watchdog timer can monitor two clock pulses. Short-circuit the CK1 and CK2 clock pins to monitor a single

cloc k pulse.

5. Inhibit ion pi n

The inhibition (INH) pin forces the watchdog timer on/off. When this pin is High level, the watchdog timer is stopped.

6. Logic circuit

The logic circuit contains flip-flops.

Flip-flop RSFF1 controls the charging and discharging of the power-on reset hold time setting capacitor (CTP).

Flip-flop RSFF2 turns on/off the circuit that accelerates charging of the power-on reset hold time setting capacitor

(CTP) at a reset. The RSFF2 operates only at a reset; it does not operate at a power-on reset when the power is

turned on.

■ABSOLUTE MAXIMUM RATINGS

*: The power supply voltage is based on the ground voltage (0 V).

WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,

temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

■RECOMMENDED OPERATING CONDITIONS

*: The watchdog timer monitor time range depends on the rating of the setting capacitor.

WARNING: The recommended operating conditions are required in order to ensure the normal operation of the

semiconductor device. All of the device’s electrical characteristics are warranted when the device is

operated within these ranges.

Always use semiconductor devices within their recommended operating condition ranges. Operation

outside these ranges may adversely affect reliability and could result in device failure.

No warranty is made with respect to uses, operating conditions, or combinations not represented on

the data sheet. Users considering application outside the listed conditions are advised to contact their

representatives beforehand.

5. Clock pulse input suppl ementation (Positive clock pulse)

■OPERATION SEQ UE NCE

1. Positive clock pulse input

See “1. Basic operation (positive clock pulse)” under “■ DIAGRAM.”

2. Negative clock pulse input

See “2. Basic operation (negative clock pulse)” under “■ DIAGRAM.”

The MB3793 operates in the same way whether it inputs positive or negative pulses.

3. Clock monitoring

To use the MB3793 while monitoring only one clock, connect clock pins CK1 and CK2.

Although the MB3793 operates basically in the same way as when monitoring two clocks, it monitors the clock

signal at every other input pulse.

See “3. Single-clock input monitoring (positive clock pulse)” under “■ DIAGRAM.”

4. Description of Operations

The numbers given to the following items correspond to numbers (1) to (13) used in “■ DIAGRAM.”

(1) The MB3793 outputs a reset signal when the supply voltage (VCC) reaches about 0.8 V (VCCL)

(2) If VCC reaches or exceeds the rise-time detected voltage VSH, the MB3 793 starts charging the power-on

reset hold time setting capacitor CTP. At this time, the output remains in a reset state. The VSH value is about

3.79 V.

Note: The MB3793 watchdog timer monitors Clock1 (CK1) and Clock2 (CK2) pulses alternately.

When a CK2 pulse is detected after detecting a CK1 pulse, the monitoring time setting

capacity (CTW) switches to charging from discharging.

When two consecutive pulses occur on one side of this alternation before switching,

the seco nd puls e is ignored.

In the above figure, pulse *1 and *2 are ignored.

MB3793-37A

(3) When CTP has been charged for a certain period of time tPR (until the CTP pin voltage exceeds the threshold

voltage (Vth) after the start of charging), the MB3793 cancels the reset (setting the RESET pin to “H” level

from “L” level).

The Vth value is about 3.6 V with VCC = 5.0 V

The power-on reset hold timer monitor time tPR is set with the following equation:

tPR (ms) A × CTP (µF)

The value of A is about 1300 with VCC = 5.0 V. The MB3793 also starts charging the watchdog timer monitor

time setting capacitor (CTW).

(4) When the voltage at the watchdog timer monitor time setting pin CTW reaches the “H” level threshold voltage

VH, the CTW switches from the charge state to the discharge state.

The value of VH is always about 1.24 V regardless of the detected voltage.

(5) If the CK2 pin inputs a clock pulse (positive edge trigger) when the CTW is being discharged in the CK1-CK2

order or simultaneously, the CTW switches from the discharge state to the charge state.

The MB3793 repeats operations (4) and (5) as long as the CK1/CK2 pin inputs clock pulses with the system

logic circuit operating normally.

(6) If no clock pulse is fed to the CK1 or CK2 pin within the watchdog timer monitor time tWD due to some problem

with the system logic circuit, the CTW pin is set to the “L” le vel threshold voltage VL or less and the MB3793

outputs a reset signal (setting the RESET pin to “L” level from “H” level).

The value of VL is alwa ys about 0.24 V regardless of the detected voltage.

The watchdog timer monitor time tWD is set with the following equation:

tWD (ms) B × CTW (µF)

The value of B is hardly aff ected by the supply voltage; it is about 1500 with VCC = 5.0 V.

(7) When a certain period of time tWR has passed (until the CTP pin voltage reaches or exceeds Vth again after

recharging the CTP), the MB3793 cancels the reset signal and starts operating the watchdog timer.

The watchdog timer monitor reset time tWR is set with the following equation:

tWR (ms) D x CTP (µF)

The value of D is about 100 with VCC = 5.0 V.

The MB3793 repeats operations (4) and (5) as long as the CK1/CK2 pin inputs clock pulses. If no clock

pulse is input, the MB3793 repeats operations (6) and (7).

(8) If VCC is lowered to the f all-time detected voltage (VSL) or less, the CTP pin voltage decrease s and the

MB3793 outputs a reset signal (setting the RESET pin to “L” level from “H” level).

The value of VSL is 3.7 V

(9) When VCC reaches or exceeds VSH again, the MB3793 starts charging the CTP.

(10) When the CTP pin voltage reaches or exceeds Vth, the MB3793 cancels the reset and restarts operating

the watchdog timer. It repeats operations (4) and (5) as long as the CK1/CK2 pin inputs clock pulses.

(11) Making the inhibit pin active (setting the INH pin to “H” from “L”) forces the watchdog timer to stop operation.

This stops only the watchdog timer, leaving the MB3793 monitoring VCC (operations (8) to (10)).

The watchdog timer remains inactive unless the inhibit input is canceled.

(12) Canceling the inhibit input (setting the INH pin to “L” from “H”) restarts the watchdog timer.

(13) The reset signal is output when the power supply is turned off to set VCC to VSL or less.

■NOTES ON USE

• Take account of common impedance when designing the earth line on a printed wiring board.

• Take measures against static electricity.

- For semiconductors, use antistatic or conductive containers.

- When storing or carrying a printed circuit board after chip mounting, put it in a conductive bag or container.

- The work table, tools and measuring instruments must be grounded.

- The worker must put on a grounding device containing 250 kΩ to 1 MΩ resistors in series.

• Do not apply a negative voltage

- Applying a negative voltage of −0.3 V or less to an LSI may generate a parasitic transistor, resulting in

malfunction.
