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 undervoltage 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
R
DS(ON)
≤
1.2
.
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 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 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 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.
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 Simplified
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.
