AP1012A
18V Dual H-Bridge Motor Driver IC
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.
