FULL-BRIDGE PWM MOTOR DRIVER

Designed for bidirectional pulse-width modulated current control of inductive loads, the A3951SB and A3951SW are capable of continuous output currents to , A and operating voltages to 50 V. Internal fixed off-time PWM current-control circuitry CAN be used to regulate the maximum load current to a desired value. The peak load current limit is set by the users selection of an input reference voltag and external sensing resistor. The fixed off-time pulse duration is set by a user-selected external RC Timing network. Internal circuit protection includes thermal shutdown with hysteresis, transient suppression Diodes and crossover-current protection. Special power- up sequencing is not required. The A3951SB and A3951SW are improved replacements for the UDN2953B and UDN2954W, respec- tively. For new system designs, the A3952SB SEB/SLB/SW are recommended. ued Product eference Only By Allegro MicroSystems, Inc.
