SI823H2BD-IS3
Overview
The SI823H2BD-IS3 is a high-performance isolated gate driver featuring symmetric 4A source and sink output current capabilities. It provides high-side/low-side driver outputs with separate VIA and VIB inputs, supporting high-speed switching for power conversion and motor control applications. This variant includes an 8V undervoltage lockout (UVLO) threshold and an enable pin for improved system safety.
Why Choose This Part
This driver offers robust isolation and high noise immunity (CMTI) essential for high-voltage environments. It includes integrated over-temperature protection and a 4A peak output current to ensure fast transition times for heavy power MOSFET and IGBT loads.
Applications
Key Specifications
Getting Started
When designing with the SI823H2BD-IS3, ensure proper decoupling capacitors are placed near the VDD and VDDA/VDDB pins to minimize switching noise. Engineers can evaluate this technology using the Skyworks Si823Hx evaluation kits to test dead-time programming and switching performance. Layout is critical; maintain sufficient creepage and clearance distances as specified for the 14-SOIC wide-body package.
