Product Introduction
MS3122 is a dual-channel full-bridge driver chip for cameras, consumerFor camera, consumer products, toys, and other low-voltage or battery-powered motion control applicationsprovides an integrated motor drive solution. The output drive module consists of N-channelComposed of DMOS driver transistors, with a built-in charge pump to generate the required gate voltage.MS3122 can provide an output current of up to 1A. It can operate atIt can operate with a motor power supply voltage of 1.8~12V and a logic power supply voltage of 2V~7V.MS3122 has a PWM (IN/IN) input interface, compatible with industry standard devicescapacity. It also features protection functions such as undervoltage lockout and overtemperature protection.
