The is a DMOS dual full bridge PWM Motor Driver with crossover-current protection and thermal shutdown circuitry. The A3995 driver is designed to drive two DC motors at currents up to 2.4A and capable of drive voltages up to 36V. It includes two independent fixed off-time PWM current regulators that operate in either fast or slow decay mode, as determined by the MODE input. Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation. Protection features includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection.
