SGM42560中文资料18V, 2.5A Three-Phase Integrated FET Motor Driver数据手册SGMICRO规格书

描述 Description

The SGM42560/1/2 family is a triple half-bridge driver, which is designed to drive three-phase brushless DC motors. The device integrates three current sense amplifiers (CSA) for sensing the three phase currents of BLDC motor.
For SGM42560, the ENx and PWMx control inputs are provided for each half-bridge. For SGM42561, the HSx (high-side control inputs) and LSx (low-side control inputs) are provided for each half-bridge, while SGM42562 has the hall-signal (Hx) interface. The required high-side gate drive voltages are generated by an internal charge pump.
The device has multiple protection functions, including under-voltage lockout (UVLO), over-current protection (OCP) and thermal shutdown (TSD). The nFAULT pin is used to indicate the fault problems.
The SGM42560/1/2 are available in a Green TQFN-3×4-24L package.
