SGM42560/SGM42561/SGM42562 18V, 2.5A Three-Phase Integrated FET Motor Drivers
■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.
