Full-Bridge PWM Motor Driver
Designed with Motorola’s advanced SMARTMOS, the 34923 is designed for
pulse-width modulated (PWM) current control of DC motors. It is capable of
continuous output currents up to 2.0 A and operating voltages of up to 45 V.
Internal fixed off-time PWM current-control timing circuitry can be programmed
via a serial interface to operate in slow, fast, and mixed current-decay modes.
DIR and PWM/ENABLE input pins are provided for use in controlling the
speed and direction of a DC motor with externally applied PWM-control
signals. The PWM/ENABLE input can be programmed via the serial port to
PWM the bridge in fast or slow current decay. Internal synchronous
rectification control circuitry is provided to reduce power dissipation during
PWM operation.
Internal circuit protection includes thermal shutdown with hysteresis and
crossover-current protection. A special power-up sequencing is not required.
