The A4952 is a full-bridge DMOS PWM motor driver designed for pulse width modulated control of DC motors with peak output currents up to ±2 A and operating voltages up to 40 V. It is packaged in a 10-pin MSOP with an exposed thermal pad (LY package), supporting thermal resistance of 48 °C/W on a 4-layer PCB. Features include overcurrent protection, internal undervoltage lockout, synchronous rectification, crossover-current protection, and a fault output. The device operates with logic input voltages from 0 to 6 V, has an adjustable PWM current limit via the VREF pin, and complies with an operating temperature range of -40 to 85 °C.
The A4952/3 offers a cost-effective solution for PWM control of DC motors, with integrated protection features and synchronous rectification for enhanced efficiency.
