Join our teamThe MC34923 is designed for pulse-width modulated (PWM) current control of dc motors, capable of driving a DC-motor at 2.0 A with PWM control, the maximum motor voltage is 45 V and slow, fast, mixed current increase decrease modes are supported.
PHASE and ENABLE input terminals are provided for use in controlling the direction and speed of a DC-motor with externally applied PWM-control signals. To PWM the bridge in fast or slow current decay, the ENABLE input can be programmed via the serial port.
Integrated 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. Unique power-up sequencing is not required
