Product Summary

The A3952SLB is a full-bridge PWM motor driver, which is designed for bidirectional pulse-width modulated current control of inductive loads. Internal circuit protection of the A3952SLB includes thermal shutdown with hysteresis, transient suppression diodes, and crossovercurrent protection. Special power-up sequencing is not required. With the ENABLE input held low, the PHASE input controls load current polarity by selecting the appropriate source and sink driver pair. The MODE input determines whether the PWM current-control circuitry operates in a slow current-decay mode (only the selected sink driver switching) or in a fast current-decay mode (selected source and sink switching). The A3952SLB is supplied in a choice of four power packages.
