Overview
The STSPIN233 is a low-voltage three-phase and three-sense motor driver produced by STMicroelectronics. This device integrates a triple half-bridge low RDS(ON) power stage in a compact VFQFPN 3 x 3 x 1.0 mm package, making it ideal for small and space-constrained applications. It is designed to operate in battery-powered scenarios and can be forced into a zero consumption state, significantly increasing battery life. The STSPIN233 supports three shunt sensing topology and offers a complete set of protection features, including overcurrent, overtemperature, and short-circuit protection.
