A4950ELJTR-T Description

Short technical summary and product information.

The A4950ELJTR-T from Allegro Microsystems is a Full-Bridge DMOS PWM Motor Driver capable of handling peak output currents up to 3.5A and operating voltages ranging from 8V to 40V. This integrated circuit is designed for precise control of DC motors using externally applied PWM signals.

 

Key features include low RDS(on) outputs, synchronous rectification for reduced power dissipation, and comprehensive internal circuit protection. This protection includes overcurrent protection (motor lead short to ground or supply), thermal shutdown with hysteresis, undervoltage monitoring of VBB, and crossover-current protection. The device supports an adjustable PWM current limit and operates with an analog interface.

 

The A4950ELJTR-T is supplied in a low-profile 8-pin SOICN package with an exposed thermal pad (suffix LJ), facilitating enhanced thermal dissipation. This package type is surface mountable. The commercial temperature grade operates from -40°C to 85°C, while the automotive grade (A4950K) is tested for -40°C to 125°C operation.

 

This motor driver is suitable for applications requiring brushed DC motor control, offering a robust solution with integrated protection features for reliable operation.
