The Allegro Microsystems A4950KLJTR-T is a Full-Bridge DMOS PWM Motor Driver capable of peak output currents up to ±3.5 A and operating voltages up to 40 V. It is designed for pulse width modulated (PWM) control of DC motors, with input terminals for speed and direction control via external PWM signals.
Key features include integrated circuit protection such as overcurrent protection, motor lead short to ground or supply protection, thermal shutdown with hysteresis, undervoltage monitoring of VBB, and crossover-current protection. The device also incorporates internal synchronous rectification control circuitry to reduce power dissipation during PWM operation.
This specific automotive grade device, the A4950K, is AEC-Q100 Grade 1 qualified and tested across extended temperature and voltage ranges for automotive or industrial applications. It operates within a commercial temperature range of –40°C to 85°C and an automotive temperature range of –40°C to 125°C. The A4950 is provided in a low-profile 8-pin SOICN package with an exposed thermal pad (suffix LJ), featuring lead (Pb) free and 100% matte tin leadframe plating.
The A4950KLJTR-T is suitable for applications requiring precise DC motor control with integrated protection features. Its DMOS technology and full-bridge output stage make it a robust solution for various automotive and industrial motor drive requirements.
