DMOS全桥式电动机驱动器; \n• Low RDS(on) outputs \n• Overcurrent protection \n• Motor lead short-to-supply protection \n• Short-to-ground protection \n• Sleep function \n• Synchronous rectification \n• Diagnostic output \n• Internal undervoltage lockout (UVLO) \n• Crossover-current protection \n;

Designed for PWM (pulse width modulated) control of DC motors, the A3950 is capable of peak output currents to ±2.8 A and operating voltages to 36 V. \n\n PHASE and ENABLE input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM control signals. Internal synchronous rectification control circuitry is provided to lower power dissipation during PWM operation. \n\n Internal circuit protection includes motor lead short-to-supply / short-to-ground, thermal shutdown with hysteresis, undervoltage monitoring of VBB and VCP, and crossover-current protection. \n\n The A3950 is supplied in a thin profile (<1.2 mm overall height) 16 pin TSSOP package (LP), and a very thin (0.75 mm nominal height) QFN/MLP package. Both packages provide an exposed pad for enhanced thermal dissipation, and are lead (Pb) free with 100% matte tin leadframe plating.\n\n
