STMicroelectronics – Low-voltage triple half-bridge motor driver for BLDC motors


The STSPIN230 from STMicroelectronics is a triple half-bridge motor driver intended for use in Brushless DC (BLDC) motors.

Housed in a small 3mm x 3mm package, the driver is ideal for battery-powered devices such as drones. It can be forced into a zero-power state, giving a marked extension to battery run-time. The high- and low-side MOSFETs in the STSPIN230’s power stage have a low total on-resistance of 0.4Ω, further contributing to efficient operation.

The device offers protection against over-currents, over-temperature and short- circuits.

• Operating-voltage range: 1.8V to 10V
• 1.3A maximum average output current
• Operating-temperature range: -40°C to 150°C
