The SGM42332 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.
The SGM42332 integrates 120° commutation based on three Hall sensor inputs. Motor speed, direction, and braking are controlled via the PWM, DIR, and nBRAKE inputs.
The device has multiple protection functions, including programmable short-circuit protection (SCP), current limit (CL), under-voltage lockout (UVLO), adjustable dead-time control, and thermal shutdown (TSD).
The SGM42332 is available in Green TSSOP-28 (Exposed Pad) and TQFN-4×4-28BL packages.
