This is a product manual of PWM amplifier released by APEX MICROTECHNOLOGY CORPORATION, the feature of this product is that it can output up to 5A continuous current, and the working voltage range is 0-60V.
The SA56 is a pulse‑width‑modulation (PWM) power amplifier designed for driving DC and stepper motors in motion‑control applications. It combines bipolar and CMOS control circuitry with DMOS power devices in a single monolithic IC, delivering up to 5 A continuous (10 A peak) output current while eliminating shoot‑through current.
The device operates from supply voltages up to 60 V, includes thermal shutdown at 160 °C, short‑circuit and over‑current protection, and offers a programmable current‑limit feature via the Ise pin. Detailed electrical specifications, performance graphs, pin descriptions, and mode‑of‑operation information are provided for designers.
