Advance Information
0.7 A Dual H-Bridge Motor Driver
with 3.0V/5.0V Compatible Logic I/O
The 17529 is a monolithic dual H-Bridge power IC ideal for portable
electronic applications containing bipolar step motors and/or brush DC-motors
(e.g., cameras and disk drive head positioners).
The 17529 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 on-board charge pump, as well as built-in shoot-through
current protection and an undervoltage shutdown function.
The 17529 has four operating modes: Forward, Reverse, Brake, and
Tri-Stated (High Impedance). The 17529 has a low total R
@25°C).
The 17529’s low output resistance and high slew rates provide efficient
drive for many types of micromotors.
Features
• Low Total R
• Output Current 0.7 A (DC), 1.4 A (Peak)
• Shoot-Through Current Protection Circuit
• 3.0 V/5.0 V CMOS-Compatible Inputs
• PWM Control Input Frequency up to 200 kHz
• Built-In Charge Pump Circuit
• Low Power Consumption
• Undervoltage Detection and Shutdown Circuit
• Pb-Free Packaging Designated by Suffix Code EV

SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 17529 is a monolithic dual H-Bridge ideal for portable
electronic applications to control bipolar step motors and brush
DC motors such as those found in camera len assemblies,
camera shutters, optical disk drives, etc. The 17529 operates
from 2.0 V to 6.8 V, providing dual H-bridge motor drivers with
parallel 3.0 V- or 5.0 V-compatible I/O. The device features an
on-board charge pump, as well as built-in shoot-through current
protection and undervoltage shutdown.

threshold. If the supply voltage drops below the undervoltage
threshold, the output power stage 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 terminals.
IN1A, IN1B, IN2A, and IN2B
These logic input terminals control each H-Bridge output.
IN1A logic HIGH = OUT1A HIGH. However, if all inputs are
taken HIGH, the outputs bridges are both tri-stated (refer to
Table 1,

DD
17529 Simplified Internal
The 17529 has four operating modes: Forward, Reverse,
Brake, and Tri-Stated (High Impedance). The MOSFETs
comprising the output bridge have a total source + sink R
≤ 1.2 Ω.
The 17529 can simultaneously drive two brush DC motors
or, as shown in the simplified application diagram on page 1,
one bipolar step motor. The drivers are designed to be PWM’ed
at frequencies up to 200 kHz.
VM1 and VM2
The VM terminals 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 terminals. All VM
terminals must be connected together on the printed circuit
board.
C1L and C1H, C2L and C2H
These two pairs of terminals, the C1L and C1H and the C2L
and C2H, connect to the external bucket capacitors required by
the internal charge pump. The typical value for the bucket
capacitors is 0.1 µF.

CEMF Snubbing Techniques
Care must be taken to protect the IC from potentially
damaging CEMF spikes induced when commutating currents in
inductive loads. Typical practice is to provide snubbing of
voltage transients by placing a capacitor or zener at the supply
terminal (VM) (see Figure 6
