Product Summary
A3958SLB is designed for pulse-width modulated (PWM) current control of dc motors. The A3958SB and A3958SLB are capable of continuous output currents to ±2 A and operating voltages to 50 V. Internal fixed offtime PWM current-control timing circuitry can be programmed via a serial interface to operate in slow, fast, and mixed current-decay modes.
Parametrics
A3958SLB absolute maximum ratings: (1)Load Supply Voltage, VBB: 50 V; (2)Output Current, IOUT: ±2.0 A; (3)Logic Supply Voltage, VDD: 7.0 V; (4)Input Voltage, VIN: -0.3 V to VDD + 0.3 V; (5)Sense Voltage, VS: 0.5 V; (6)Reference Voltage, VREF: 2.7 V; (7)Package Power Dissipation (TA = 25℃), PD: 2.2 W*; (8)Operating Temperature Range,TA: -20℃ to +85℃; (9)Junction Temperature,TJ: +150℃; (10)Storage Temperature Range, TS: -55℃ to +150℃.
Features
A3958SLB features: (1)±2 A, 50 V Continuous Output Rating; (2)Low rDS(on) Outputs (270 mΩ, Typical); (3)Programmable Mixed, Fast, and Slow Current-Decay Modes; (4)Serial Interface Controls Chip Functions; (5)Synchronous Rectification for Low Power Dissipation; (6)Internal UVLO and Thermal-Shutdown Circuitry; (7)Crossover-Current Protection.
