FD1257AH Datasheet Smart Motor Driver

Manufacturer: Feeling Technology

Overview: FEELING TECHNOLOGY.

General Description

FD1257AH is a single-phase full wave motor driver with embedded Hall-effect sensor IC.

It integrates a H-bridge MOS driver, a high sensitivity hall-effect sensor, an event timer for rotor locked in SIP-4L package, which make the motors’ PCBs(printed circuit boards) design easy and fabricate the high efficiency DC motors or FANs as simply as possible.

For safety, Lock-shutdown function would turn the IC’s internal drivers off avoiding over-heat when the rotor is locked, and IC will try to re-start the rotor’s torque after the time of these drivers’ shutdown.

Key Features
