[AP1012A] MS1493-E-03 2014/12 - 1 - 1. Genaral Description The AP1012A is a dual H-bridge motor driver which has four drive modes: forward, reverse, brake and standby, to operate up to 18V motor supply voltage. An N-channel LDMOS is built in for both high and low sides of the output driver to minimize the device size. Additionally, the AP1012A has under voltage detection and thermal shutdown circuits. It is housed in a small 24-pin QFN package, suitable for driving various types of small motors. 2.
