Introduction

The SLMi823x isolated driver family is an isolated dual channel gate driver with different configurations. The SLMi8230/1/3/4 are configured as high-side/lowside drivers, while the SLMi8232/5 are configured as dual drivers. The peak source output current of SLMi8230/1/2 is 1.0A and the peak source output current of SLMi8233/4/5 is 4.0A. Programmable dead time (DT) feature is available in SLMi8230/1/3/4. Pulling high the DIS pin shuts down both outputs simultaneously, and allows for normal operation when the DIS pin is open or pulled low. As a fail-safe measure, primary-side logic failures force both outputs low. The VDDA and VDDB supply voltage are up to 40V. A wide input VDDI range from 3V to 18V makes the driver suitable for interfacing with both analog and digital controllers. All the supply voltage pins have under voltage lock-out (UVLO) protection. The SLMi823x has 5.0kVRMS isolation in SOP16W package per UL1577. High CMTI, low propagation delay, small size and flexible configuration make the SLMi823x family is suitable for a wide range of isolated MOSFET/IGBT and SiC or GaN FET gate drive applications.
