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
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
CONTROL CIRCUIT POWER SUPPLY (VDD)
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.
LOGIC INPUT CONTROL (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 5, Truth Table
, page
7
).
OUTPUT ENABLE (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 input (IN1A, IN1B, IN2A, and IN2B) states.
H-BRIDGE OUTPUT (OUT1A, OUT1B, OUT2A, AND
OUT2B)
These terminals provide connection to the outputs of each
of the internal H-Bridges (see
Figure 2, 17529 Simplified
Internal Block Diagram
, page
2
).
MOTOR DRIVE POWER SUPPLY (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.
CHARGE PUMP (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.
PREDRIVER POWER SUPPLY (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 VCRES voltage is power supply for internal
predriver circuit of H-Bridges.
POWER GROUND (PGND)
Power ground terminals. They must be tied together on the
PCB.
LOGIC GROUND (LGND)
Logic ground terminal.
