ATA6821-TUQ Description

The ATA6821 is a single-channel high-speed power driver IC designed with Atmel's0.8 µm BCDMOS technology. With its extremly short propagation delay and super fastslew rates, the ATA6821 is ideally suited to control MOSFETs or IGBTs in a widerange of automotive and industrial high-speed applications. The push-pull outputstage is capable of driving peak currents of 4 A.The ATA6821 is designed to control high currents as they can be found in electricalmachines or in power converters. The ATA6821 is tailored to control low resistanceswitching devices by a potential-free input signal.The ATA6821’s full automotive qualification, ESD protection and protection againsttransients according to ISO/TR 7637/1 guarantees security for all kind of applications.Rev. 4778A–AUTO–11/03
