Product Summary

The A3959SLP is a DMOS full-bridge PWM motor driver. Designed for pulse-width modulated (PWM) current control of dc motors, the A3959SLP is capable of output currents to ±3 A and operating voltages to 50 V. Internal fixed off-time PWM current-control timing circuitry can be adjusted via control inputs to operate in slow, fast, and mixed current-decay modes.

Parametrics

A3959SLP absolute maximum ratings: (1)Load Supply Voltage, VBB: 50 V; (2)Output Current, IOUT (Repetitive): ±3.0 A; (Peak, <3 μs): ±6.0 A; (3)Logic Supply Voltage, VDD: 7.0 V; (4)Logic Input Voltage Range, VIN, (Continuous): -0.3 V to VDD + 0.3 V; (tw <30 ns): -1.0 V to VDD + 1.0 V; (5)Sense Voltage, VS (Continuous): 0.5 V; (tw <3 μs): 2.5 V; (6)Reference Voltage, VREF: VDD; (7)Storage Temp. Range, TS: -55 to +150℃; (8)Operating Temp. Range, TA: -20 to +85℃; (9)Junction Temperature, TJ: +150℃.

Features

A3959SLP features: (1)±3 A, 50 V Output Rating; (2)Low rDS(on) Outputs (270 mΩ, Typical); (3)Mixed, Fast, and Slow Current-Decay Modes; (4)Synchronous Rectification for Low Power Dissipation; (5)Internal UVLO and Thermal-Shutdown Circuitry; (6)Crossover-Current Protection; (7)Internal Oscillator for Digital PWM Timing.
