DESCRIPTION

· The ATA6826 is a fully protected Triple Half-bridge designed in Smart Power SOI Technology.

· It is used to control up to 3 different loads by a microcontroller in automotive and industrial applications.

· Each of the 3 high-side and 3 low-side drivers is capable of driving currents up to 1.0A.

· The drivers are internally connected to form 3 half-bridges and can be controlled separately from a standard serial data interface.

· The IC design supports the application of H-bridges to drive DC motors.

· Protection is guaranteed regarding short-circuit conditions, overtemperature, and undervoltage.

· Various diagnostic functions and a very low quiescent current in standby mode open a wide range of applications.

· Automotive qualification enhances quality for exacting requirements of automotive applications.

FEATURES

· Supply Voltage up to 40V.

· RDSon Typically 0.8 Ω at 25°C, Maximum 1.5 Ω at 150°C.

· Up to 1.0A Output Current.

· Three Half-bridge Outputs Formed by Three High-side and Three Low-side Drivers.

· Capable of Switching all Kinds of Loads Such as DC Motors, Bulbs, Resistors, Capacitors, and Inductors.

· No Shoot-through Current.

· Very Low Quiescent Current IS< 2 µA in Standby Mode versus Total Temperature Range.

· Outputs Short-circuit Protected.

· Overtemperature Protection for Each Switch and Overtemperature Prewarning.

· Undervoltage Protection.

· Various Diagnostic Functions Such as Shorted Output, Open-load, Overtemperature, and Power-supply Fail Detection.

· Serial Data Interface, Daisy Chain Capable, up to 2 MHz Clock Frequency.

· SO14 Power Package.
