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.
Thermal-shutdown protection (TSD) ensures the internal drivers of IC are operating under a safe operating
temperature range.
All the protection mechanisms mentioned above combine to provide a complete protecting scenario in the motor
system and avoid any possible damages and guarantee under a correct and safe operation.
