DESCRIPTION

The SGM42560 provides three integrated half-bridge MOSFET drivers for driving a three-phase brushless DC (BLDC) motor. This device integrates three current sense amplifiers (CSA) for sensing the three phase currents of BLDC motor. The SGM42560 has ENx and PWMx control inputs for each half-bridge. It uses an internal charge pump to generate the gate drive supply voltage for the HS FETs, and a trickle charge circuit that maintains sufficient gate drive voltage to operate at 100% duty cycle.

Internal protection functions are provided for under-voltage lockout (UVLO), over-current protection (OCP) and thermal shutdown (TSD). Fault conditions are indicated by the nFAULT pin. The SGM42560 is available in a Green TQFN-3×4-24L package.
