Description
3974 LOAD 43 SUPPLY1 SENSE1 OUT1A ENABLE1 GND GND GND NC OUT1B NC NC DMOS DUAL FULL-BRIDGE PWM MOTOR DRIVER Designed for pulse-width modulated (PWM) .Features
* s ±1.5 A, 50 V Continuous Output Rating s Low rDS(on) DMOS Output Drivers s Programmable Slow, Fast, and Mixed Current-Decay Modes s Serial-Interface Controls Chip Functions s Synchronous Rectification for Low Power Dissipation s Internal UVLO and Thermal Shutdown Circuitry s Crossover-Current ProteApplications
* saving cost and external component count, while minimizing power dissipation. Internal circuit protection includes thermal shutdown with hysteresis, undervoltage monitoring of VDD and the charge pump, and crossover-current protection. Special power-up sequencing is not required. The A3974SED is sup3974 Distributors
