AP1018
18V Dual H-Bridge Motor Driver IC
1. General Description
The AP1018 is a Dual H-Bridge small motor driver corresponding to the motor drive voltage 18V.
Since the AP1018 has two output channels, it is capable of driving two DC motors or one stepper motor.
It can be used up to peak current of 4.5A, so it can be used safely even with a motor that requires a large
current at the start of driving.
Also it has under voltage detection and thermal shut down circuits as a protection circuit.
The AP1018 is housed in a high heat dissipation 24-pin QFN package (4mm x 4mm) with an exposed
pad. It is a motor driver IC that realizes reduction of mounting area.
