Description
The ATA6821 is a single-channel high-speed power driver IC designed with Atmel's
0.8 µm BCDMOS technology. With its extremly short propagation delay and super fast
slew rates, the ATA6821 is ideally suited to control MOSFETs or IGBTs in a wide
range of automotive and industrial high-speed applications. The push-pull output
stage is capable of driving peak currents of 4 A.
The ATA6821 is designed to control high currents as they can be found in electrical
machines or in power converters. The ATA6821 is tailored to control low resistance
switching devices by a potential-free input signal.
The ATA6821’s full automotive qualification, ESD protection and protection against
transients according to ISO/TR 7637/1 guarantees security for all kind of applications.
