Description
Designed for pulse width modulated (PWM) control of DC motors, the A4950 is capable of peak output currents to ±3.5 A and operating voltages to 40 V.
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 lower power dissipation during PWM operation.
Internal circuit protection includes overcurrent protection, motor lead short to ground or supply, thermal shutdown with hysteresis, undervoltage monitoring of VBB, and crossover current protection.
Features and Benefits
? Low RDS(on) outputs
? Overcurrent protection (OCP)
? Motor short protection
? Motor lead short to ground protection
? Motor lead short to battery protection
? Low Power Standby mode
? Adjustable PWM current limit
? Synchronous rectification
? Internal undervoltage lockout (UVLO)
? Crossover-current protection
? Commercial temperature grade (A4950E: –40°C to 85°C )
? Automotive temperature grade (A4950K: –40°C to 125°C)
