    DESCRIPTION
    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 package. Both packages provide an exposed pad
    for enhanced thermal dissipation, and are lead (Pb) free with
    100% matte tin leadframe platin
