About This Product

■Summary

NJW4381 is a dual H-bridge driver IC for various actuators that pursues versatility. The control section has a Mode Select function that allows you to select the most suitable control between the 2-input method and the Phase & Enable method. The input section uses a Schmitt inverter circuit with excellent noise resistance. The output section consists of two independent H bridge circuits. The protection circuit includes an overcurrent protection (OCP) circuit, an undervoltage lockout (UVLO) circuit, and a thermal shutdown (TSD) circuit, and outputs an alarm signal when an OCP/TSD error occurs. In addition to single power supply operation that does not require a power supply for the logic section, it is also possible to use different motor section voltages for each bridge. In addition, the interface voltage supports various logics of 3.3V/5.0V. With its functionality that combines high efficiency and high output performance such as withstand voltage of 40V, output current of 1.5A, low current consumption, and low ON resistance, as well as versatility such as support for various PWM controls, it can be used in a variety of applications such as small stepping motors, DC motors, solenoids, etc. It can be used for a wide range of applications using a standard actuator.
