Motor Drivers
The AP1018 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.
