A3971SLB Product Details
Low rps(on) DMOS output drivers provide low power dissipation during PWM operation. Internal charge pump circuitry is used to create a boosted voltage to fully enhance the high-side DMOS switches.
Three TTL-compatible logic-input terminals per bridge allow flex-ibility in configuring PWM control.
Internal circuit protection includes thermal shutdown with hysteresis, and crossover-current protection. Special power-up sequencing is not required.
The A3971SLB is supplied in a 24-lead plastic SOIC with a copper batwing tab. The power tab is at ground potential and needs no electri-cal isolation.
FEATURES
■ ±2.5 A Load Current Capability per Bridge
■ Parallel Outputs for 5 A Load-Current Capability
■ Low rDS(on) Outputs Typically 325 mΩ source, 175 mΩ sink
■ Synchronous Rectification via Control Logic
■ Internal Undervoltage Monitor
■ Crossover-Current Protection
■ Source Connections for External Current Sensing
■ Thermal Shutdown Circuitry
