3 Description

The TMP821 device is a two-phase half-wave motor

predriver that is suited for fan motors, which has

winding in push-pull configuration. It uses differential

hall effect sensors for commutation signals for two of

the switches in power circuit. The device has a very

small pin count, making it very simple to use.
