0.7 A 6.8 V Dual H-Bridge Motor
Driver
The 17533 is a monolithic dual H-Bridge power IC ideal for portable
electronic applications containing bipolar stepper motors and/or brush
DC-motors (e.g., cameras and disk drive head positioners).
The 17533 operates from 2.0 V to 6.8 V, with independent control of
each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-compatible
logic). The device features built-in shoot-through current protection
and an undervoltage shutdown function.
The 17533 has four operating modes: Forward, Reverse, Brake,
and Tri-Stated (High Impedance). The 17533 has a low total RDS(ON)
of 1.2 Ω (max @ 25°C).
The 17533’s low output resistan ce and high slew rates provide
efficient drive for many types of micromotors.
Features
• Low Total RDS(ON) 0.8 Ω (Typ), 1.2 Ω (Max) @ 25°C
• Output Current 0.7 A (DC), 1.4 A (Peak)
• Shoot-Through Current Protectio n Circuit
•3.0 V/ 5.0 V CMOS-Compatible Inputs
• PWM Control Input Frequency up to 200 kHz
• Built-In 2-Channel H-Bridge Driver
• Low Power Consumption
• Undervoltage Detection and Shutdown Circuit
• Pb-Free Packaging Designated by Suffix Code EV

FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 17533 is a monolithic dual H-Bridge ideal for portable
electronic applications to control bipolar stepper motors and
brush DC motors such as those found in camera len
assemblies, camera shutters, optical disk drives, etc.
The 17533 operates from 2.0 V to 6.8 V, with independent
control of each H-Bridge via parallel MCU interface (3.0 V-
and 5.0 V-compatible I/O). The device features built-in shoot-
through current protection and undervol ta ge shutdown.
The 17533 has four operating modes: Forward, Reverse,
Brake, and Tri-Stated (High Impedance). The MOSFETs
comprising the output bridge have a total source + sink
RDS(ON) ≤ 1.2 Ω.
The 17533 can simultaneously drive two brush DC motors
or, as shown in the simplified application diagram on page 1,
one bipolar stepper motor. The drivers are designed to be
PWM’ed at frequencies up to 200 kHz.
FUNCTIONAL PIN DESCRIPTION
LOGIC SUPPLY (VDD)
The VDD pin carries the logic supply voltage and current
into the logic sections of the IC. VDD has an undervoltage
threshold. If the supply voltage drops below the undervoltage
threshold, the output power stag e switches to a tri-state
condition. When the supply voltage returns to a level that is
above the threshold, the power stage automatically resumes
normal operation according to the established condition of
the input control pins.
LOGIC INPUT CONTROL (IN1A, IN1B, IN2A, AND
IN2B)
These logic input pins control each H-Bridge output (e.g.,
IN1A logic HIGH = OUT1A HIGH, etc.). However, if all inputs
are taken HIGH, the outputs bridges are both tri-stated (refer
to Table 5, Truth Table, page 7).
OUTPUT ENABLE (OE)
The OE pin is a LOW = TRUE ena ble input. When
OE = HIGH, all H-Bridge outputs (OUT1A, OUT1B, OUT2A,
and OUT2B) are tri-stated (high-impedance), regardless of
logic inputs (IN1A, IN1B, IN2A, and IN2B) states.
OUTPUT A AND B OF H-BRIDGE CHANNEL 1 AND
2 (OUT1A, OUT1B, OUT2A, AND OUT2B)
These pins provide connection to the outputs of each of
the internal H-Bridges (see Figure 2, 17533 Simplifi ed
Internal Block Diagram, page 2).
MOTOR DRIVE POWER SUPPLY (VM1 AND VM2)
The VM pins carry the main supply voltage and current into
the power sections of the IC. This supply then becomes
controlled and/or modulated by the IC as it delivers the power
to the loads attached between the output pins. All VM pins
must be connected together on the printed circuit board.
GATE DRIVER CIRCUIT VOLTAGE INPUT (VG)
The VG pin is the input pin for the gate drive voltage.
POWER GROUND (PGND)
Power ground pins. They must be tied together on the
PCB.
LOGIC GROUND (LGND)
Logic ground pin.

TYPICAL APPLICATIONS
INTRODUCTION
TYPICAL APPLICATIONS
INTRODUCTION
Figure 6 shows a typical appli ca tion for the 17533. When
applying the gate voltage to the VG pin from an external
source, be sure to connect it via a resistor equal to, or greater
than, RG = VG / 0.02 Ω.
Care must be taken to provide sufficient gate-source
voltage for the high-side MOSFETs when VM >> VDD (e.g.,
VM = 5.0 V, VDD = 3.0 V), in order to ensure full enhancement
of the high-side MOSFET channels.
Figure 6. 17533 Typical Application Diagram
CEMF SNUBBING TECHNIQUES
Care must be taken to protect the IC from potentially
damaging CEMF spikes induced when commuting currents
in inductive loads. Typical practice is to provide snubbing of
voltage transients by placing a zener or a capacitor at the
supply pin (VM) (see Figure 7).
Figure 7. CEMF Snubbing Techniques
PCB LAYOUT
When designing the printed circuit board (PCB), connect
sufficient capacitance between power supply and ground
pins to ensure proper filtering from transients. For all high-
current paths, use wide copper traces and shortest possible
distances.
