DESCRIPTION

The SGM42553 provides three individually controllable half-H-bridge drivers. The device is intended to drive a three-phase brushless-DC motor, although it can also be used to drive solenoids or other loads. Each output driver channel consists of N-channel power MOSFETs configured in a 1/2-H-bridge configuration. Each 1/2-H-bridge driver has a dedicated ground terminal, which allows independent external current sensing.
An uncommitted comparator is integrated into the SGM42553, which allows for the construction of current-limit circuitry or other functions.
Internal protection functions are provided for under-voltage, charge pump faults, over-current, short-circuits, and over-temperature. Fault conditions are indicated by the nFAULT pin.
The SGM42553 is available in Green TQFN-6×6-36L and TSSOP-28 (Exposed Pad) packages.
