A3958SLB-T Description

Short technical summary and product information.

The A3958SLB-T from Allegro Microsystems is a DMOS Full-Bridge PWM Motor Driver. It is designed for pulse width modulated (PWM) current control of DC motors, capable of continuous output currents to 2A and operating voltages to 50V.

 

Key features include programmable mixed, fast, and slow current-decay modes controlled via a serial interface. The device also incorporates synchronous rectification for reduced power dissipation and internal protection circuitry including thermal shutdown and crossover-current protection. It operates over a temperature range of -20°C to 150°C (TJ).

 

This motor driver is supplied in a 24-pin SOIC package with internally fused pins, suitable for surface mounting. The power pins are at ground potential and require no electrical isolation. Its applications are general purpose, making it suitable for various DC motor control needs.
