INFORMACIJE O IZDELKU
Pregled izdelka
The A3959SB-T is a DMOS full-bridge PWM Motor Driver IC with crossover-current protection. The A3959 driver is designed for pulse width modulated current control of DC motors, capable of output currents to ±3A and operating voltages to 50V. 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. The PHASE and ENABLE input terminals are provided for use in controlling the speed and direction of a 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, under-voltage monitoring of supply and charge pump and crossover-current protection.
