Full-Bridge DMOS PWM Motor Driver
Designed for pulse width modulated (PWM) control of DC motors, the A4950 is capable of peak output currents to ±3.5A 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 crossovercurrent protection. For high ambient operating temperature applications, an automotive grade device is offered (A4950K). The K grade device is tested across
extended temperature and voltage ranges to ensure compliance in automotive or industrial applications. The A4950 is provided in a low-profile 8-pin SOICN package with exposed thermal pad (suffix LJ) that is lead (Pb) free, with 100% matte tin
leadframe plating
