SI823H3BD-AS3

Isolators - Gate Drivers Overview

The SI823H3BD-AS3 is an automotive-grade, isolated gate driver from the Si823Hx series by Skyworks Solutions. It features a single-channel high-side driver with capacitive coupling technology providing 5000Vrms isolation. The device operates within a supply voltage range of 3 V to 5.5 V and supports output voltages up to 30 V. Key electrical specifications include a maximum propagation delay of 30 ns, with rise and fall times of 12 ns each. It is housed in a 14-SOIC package and functions as a non-inverting TTL logic interface.
