Product Introduction

Overview

The PM8834 is a flexible, high-frequency dual low-side driver specifically designed to work with high capacitive MOSFETs and IGBTs. It is produced by STMicroelectronics and is ideal for applications requiring high driving currents and fast switching times. The device features dual independent low-side drivers, each capable of sinking and sourcing 4 A, with the option to parallel the outputs for higher driving capability. It operates with a CMOS/TTL-compatible PWM signal and has a wide input supply voltage range of 5 V to 18 V. The PM8834 is available in SO8 and MSOP8 packages with an exposed pad, making it suitable for various industrial and power management applications.
