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)
