Product Details

MICROSTEPPING DMOS DRIVER WITH TRANSLATOR

motor drivers dissipation.

The translator is the key to the easy implementation of the A3977. By simply inputting one pulse on the STEP input the motor will take one step (full, half, quarter, or eighth depending on two logic inputs). There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. The A3977 interface is an ideal fit for applications where a complex µP is unavailable or over-burdened.

FEATURES
■ ±2.5 A, 35 V Output Rating
■ Low rDS(on) Outputs, 0.45 Ω Source, 0.36 Ω Sink Typical
■ Automatic Current Decay Mode Detection/Selection
■ 3.0 V to 5.5 V Logic Supply Voltage Range
■ Mixed, Fast, and Slow Current Decay Modes
■ Home Output
■ Synchronous Rectification for Low Power Dissipation
■ Internal UVLO and Thermal Shutdown Circuitry
■ Crossover-Current Protection
