Introduction

L9110S is a two-channel push-pull power amplifier ASIC designed to control the driving motor. It integrates discrete circuits into a single IC, which reduces the number of peripheral devices, reduces the cost and improves the reliability of the whole machine. L9110S chip has two input control terminals, which can control two output terminals to directly drive the forward and backward rotation of the motor. The chip is widely used in motor drive of toy cars,pulse electromagnetic valve drive, stepping motor drive, switching power tube and other circuits.
