AP1012
18V Dual H-Bridge Motor Driver IC
Overview
The AP1012 is the dual H-bridge motor driver which has four drive modes, forward, reverse, brake and
standby, to operate up to 18V motor supply voltage. N type LDMOS is built in both high and low side for
output driver to achieve small package. It also has under voltage detection and thermal shut down circuits.
It is suitable for driving various types of small motors.

(Note1) All above voltage is defined to DGND/PGND terminal voltage
(Note2) The use under the condition which exceeds the absolute maximum ratings even momentarily
may damage the product quality. That is, the absolute maximum ratings are rated values at which the
products on the verge of suffering physical damages.
(Note3) The rating is calculated by RθJ=40C/W under the condition when 4layer board is used. EP
terminal is connected to ground. Compliant to SEMI JEDEC JESD51-6, JESD51-7.
(Note4) Logic terminal supply voltage, VIO, needs to be turned on prior to or at the same time as Control
supply voltage, VC.
