A4953 Description
Designed for pulse width modulated (PWM) control of DC motors, the A4952 and A4953 are capable of peak output currents to ±2 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.
A4953 Key Features
- Low RDS(on) outputs
- Overcurrent protection (OCP)
- Low Power Standby mode
- Adjustable PWM current limit
- Synchronous rectification
- Internal undervoltage lockout (UVLO)
- Crossover-current protection
- Fault output (A4952 only)
- Selectable retry (A4952 only)
