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.
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
.
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.
FUNCTIONAL TERMINAL DESCRIPTION
V
DD
The V
DD
terminal carries the logic supply voltage and current
into the logic sections of the IC. V
DD
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 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, Truth Table
, page 7).
OE
The
OE
terminal 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 inputs (IN1A, IN1B, IN2A, and IN2B) states.
OUT1A, OUT1B, OUT2A, and OUT2B
These terminals provide connection to the outputs of each of
the internal H-Bridges (see
Figure 1, 17529 Simplified Internal
Block Diagram
, page 2).
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
μ
F.
C
RES
The C
RES
terminal is the output of the internal charge pump.
Its output voltage is approximately three times the V
DD
voltage.
The
VC
RES
voltage is power supply for internal predriver circuit
of H-Bridges.
PGND
Power ground terminals. They must be tied together on the
PCB.
LGND
Logic ground terminal.
F
Freescale Semiconductor, Inc.
