The SGM42330/1 family is a three-phase BLDC gate driver. It is designed to drive three half-bridges composed of six N-channel power MOSFETs, and supports an input voltage range of 5V to 60V.
These devices generate the gate drive voltages using an internal charge pump and enhance the high-side MOSFETs using a bootstrap circuit. Even if the output works at 100% duty cycle, the internal trickle-charge circuit can maintain enough high-side gate driver voltage.
For SGM42330, the ENx and PWMx control inputs are provided for each half-bridge. For SGM42331, the HSx (high-side control inputs) and LSx (low-side control inputs) are provided for each half-bridge.
The device has multiple protection functions, including programmable short-circuit protection (SCP), over-current protection (OCP), under-voltage lockout (UVLO), adjustable dead-time control, and thermal shutdown (TSD).
The SGM42330/1 is available in Green TSSOP-28 (Exposed Pad) and TQFN-4×4-28BL packages.
