ATA6822

The ATA6822 is a fully protected driver interface designed in 0.8 µm BCDMOS technology. It is used to control different loads by setting two logic level input signals. The ATA6822 can be configured to cover a wide range of automotive and industrial applications. Each of the push-pull output stages is capable to drive currents up to 1.3 A. The drivers are connected internally to form two half-bridges and can be controlled separately with two logic level input signals. Therefore, all kinds of loads such as bulbs, resistors, capacitors and inductors can be combined. The IC design supports the application as a DC motor driver especially. Protection is guaranteed in terms of short-circuit conditions, overtemperature and overvoltage up to 40 V supply voltage. A diagnosis function in case of overtemperature and overvoltage is embedded. To reduce the overall current consumption the ATA6822 can be switched into standby mode. The output pins are designed to withstand DC voltages up to 40 V. Automotive qualification referring to conducted interferences, EMC protection and 2 kV ESD protection gives added value and enhanced quality for demanding up-market applications.
