SYSTEM / APPLICATION INFORMATION
INTRODUCTION
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 lens
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
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 DS(ON) ≤ 1.2 Ω .
The 17529 can simultaneously drive two brush DC motors

designed to be PWM’ed at frequencies up to 200 kHz.
shutdown.
FUNCTIONAL PIN DESCRIPTION
CONTROL CIRCUIT POWER 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 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 pins.
LOGIC INPUT CONTROL (IN1A, IN1B, IN2A, AND
IN2B)
These logic input pins 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
OUTPUT ENABLE (OE)
The OE pin is a LOW = TRUE enable input. When
OE = HIGH, all H-Bridge outputs (OUT1A, OUT1B, OUT2A,
and OUT2B) are tri-stated (high-impedance), regardless of
logic input (IN1A, IN1B, IN2A, and IN2B) states.
H-BRIDGE OUTPUT (OUT1A, OUT1B, OUT2A, AND
OUT2B)
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.
CHARGE PUMP (C1L AND C1H, C2L AND C2H)
These two pairs of pins, 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 μ F.
PRE-DRIVER POWER SUPPLY (CRES)
The CRES pin is the output of the internal charge pump.
Its output voltage is approximately three times the V DD
voltage. The V CRES voltage is power supply for internal pre-
driver circuit of H-Bridges.
POWER GROUND (PGND)
Power ground pins. They must be tied together on the
PCB.
LOGIC GROUND (LGND)
Logic ground pin.
These pins provide connection to the outputs of each of
