Description
The STSPIN240 is a dual brush DC motor driver
integrating a low R
DS(ON)
power stage in a small
QFN 3 x 3 mm package.
Both the full-bridges implement an independent
PWM current controller with fixed OFF time.
The device is designed to operate in battery-
powered scenarios and can be forced into a zero-
consumption state allowing a significant increase
in battery life.
The device offers a complete set of protection
features including overcurrent, overtemperature
and short-circuit protection.
QFN 3 x 3 mm (16-pin)
