A4950ELJTR-T

The A4950ELJTR-T is a full bridge DMOS PWM motor driver in 8 pin NSOIC package. It is designed for pulse width modulated (PWM) control of DC motors. Input terminals are provided for use in controlling speed and direction of DC motor with external PWM control signals. Internal synchronous rectification control circuitry is provided for low 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.

• Output currents of 3.5A
• Load supply voltage of 40V
• Low RDS(on) outputs
• Low power standby mode
• Adjustable PWM current limit
• Synchronous rectification
• Internal undervoltage lockout (UVLO)
• Load supply voltage range from 8V to 40 V
• Ambient operating temperature from -40°C to 85°C
