SI8273GB-AM1

Isolators - Gate Drivers Overview

The SI8273GB-AM1 is a single-channel, high-speed isolated gate driver from the Si827x series by Skyworks Solutions. It utilizes capacitive coupling technology to provide galvanic isolation with a rated insulation voltage of 2500 Vrms. The device features a peak output current capability of 4 A, supporting both high-side and low-side configurations. Key electrical parameters include a maximum propagation delay of 75 ns, with typical rise and fall times of 10.5 ns and 13.3 ns respectively. It operates within a temperature range of -40°C to +125°C and is housed in a 14-QFN (5x5 mm) surface-mount package.
