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.
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.
Internal circuit protection includes motor lead short-tosupply / short-to-ground, thermal shutdown with hysteresis, undervoltage monitoring of VBB and VCP, and crossover-current protection.
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.
