The SGM42553 is a triple half-bridge driver, and each channel is controlled by separate controllable input. This device is designed to drive a three-phase brushless DC motor, as well as solenoids or other loads. The output driver block for each consists of N-MOSFETs configured as half-bridge to drive the motor. This device integrates three dedicated ground terminals (PGNDx) for each channel to sense the external current independently.
The SGM42553 integrates a comparator, which can be used if current limit function is needed in the motor system.
A number of protection features are provided in the device including under-voltage lockout, short-circuit, over-current and over-temperature shutdown. The nFAULT pin is used to indicate the fault problems.
The SGM42553 is available in Green TQFN-6×6-36AL and TSSOP-28 (Exposed Pad) packages.
