Description
Designed for pulse width modulated (PWM) current control of DC motors, the
A3959 is capable of output currents to ±3 A and operating voltages to 50 V.
Internal fixed off-time PWM current control timing circuitry can be adjusted
via control inputs to operate in slow, fast, and mixed current-decay modes.
PHASE and ENABLE input terminals are provided for use in controlling the speed
and direction of a DC motor with externally applied PWM-control signals.
Internal synchronous rectification control circuitry is provided to reduce
power dissipation during PWM operation.
Internal circuit protection includes thermal shutdown with hysteresis,
undervoltage monitoring of supply and charge pump, and crossover-current
protection. Special power-up sequencing is not required.
