FD1157H-G1数据手册AAT中文资料规格书

描述 Description

\tFD1157H is a two-phase half-wave BLDC motor driver IC. It integrates the complementary open drain MOSFET, a high sensitivity Hall-effect sensor and a digital control logic for rotor locked shutdown and re-start control, which simplifies the PCB(printed circuit board) design and make the fabrication of small-size BLDC motors possible. 

\tOutput BTL soft-switching is used to reduce the BLDC motors vibration and acoustic noise.

\tFor 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.

\tThe Thermal shutdown protection ensures the BLDC motors to operate under specified temperature ranges.
