STMicroelectronics STSPIN233 low voltage motor driver

The STSPIN233 device integrates a triple half-bridge low RDS(ON) power stage in a small VFQFPN 3 x 3 x 1.0 mm package ideal for small and space constrained applications.

The device is designed to operate in battery-powered scenarios and can be forced in a zero consumption state, allowing a significant increase in battery life.

The STSPIN233 is supporting three shunt sensing topology.

The device offers a complete set of protection including overcurrent, overtemperature and short-circuit protection.
