General Description
FD170H is a complementary dual pre-drivers output with embedded Hall-effect sensor IC. It integrates a output
clamping totem-pole drivers for NPN or NMOS drivers, a high sensitivity hall-effect sensor, an event timer for rotor
locked in SIP-4L package, which make this solution operation under a high power conditions of 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.
