Overview

The Skyworks Solutions SI823H1BD-IS3 is a robust, isolated gate driver designed for high-power applications. It features high-side and low-side drivers with independent inputs, enabling flexible control of MOSFETs and IGBTs. This device incorporates essential protection features to enhance system reliability and safety.

Why Choose This Part

This gate driver offers a high output current of up to 4A, suitable for switching large MOSFETs and IGBTs. It includes critical safety features like over-temperature protection, output undervoltage lockout (UVLO) fault detection, and fail-safe drivers that default low upon loss of input side power. Operating over a wide temperature range of -40C to 125C, it ensures reliable performance in harsh environments.

Applications

Motor Control Systems
Provides isolated gate driving for brushed DC, brushless DC (BLDC), and AC induction motors, ensuring efficient and safe operation of motor drives.
Power Delivery Systems
Suitable for driving power switches in various power delivery architectures, including server power supplies and telecom power systems, where isolation and robust gate drive are critical.
Isolated DC-DC Power Supplies
