Full-bridge DMOS PWM motor driver IC
An automotive version of the A4950 full-bridge motor driver IC is now available from Allegro MicroSystems Europe. The A4950 is designed for pulse width modulated (PWM) control of DC motors, and is capable of peak output currents to ±3.5 A and operating voltages to 40 V. The device is AECQ100 Grade 1 qualified and is rated over an extended ambient operating temperature range of -40°C to 125°C.
The A simple logic interface is available to control the speed and direction of a DC motor with externally applied PWM control signals. Internal synchronous rectification control circuitry is provided to reduce the power dissipation during PWM operation.
Internal circuit protection includes overcurrent protection, motor-lead short-circuit to ground or supply, thermal shutdown with hysteresis, undervoltage monitoring of load supply voltage, and crossover current protection.
The A4950 is supplied in a low-profile 8-pin SOICN package with exposed thermal pad (suffix LJ) that is lead (Pb) free, with 100% matt tin leadframe plating.
