COMPLEMENTARY OUTPUT POWER HALL® LATCH
Type UGN5275K latching Hall-effect sensors are bipolar integrated circuits designed for electronic commutation of brushless dc motors. They feature open-collector complementary power outputs that are capable of sinking up to 300 mA continuously. Increased current ratings, complementary outputs, and sensitive switching points that are stable over temperature and time ideally suit these devices for minimum-component brushless dc motor designs. Each sensor IC includes a Hall-voltage generator, an operational amplifier, a Schmitt trigger, a voltage regulator, and large-area dual npn-output transistors. The regulator allows the IC to operate with supply voltages ranging from 4.5 V to 14 V.
