1. Description
The ATA6826 is a fully protected Triple Half-bridge designed in Smart Power SOI
Technology, 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. Therefore, all kinds of loads such as
bulbs, resistors, capacitors and inductors can be combined. The IC design especially
supports the application of H-bridges to drive DC motors.
Protection is guaranteed regarding short-circuit conditions, overtemperature and und-
ervoltage. Various diagnostic functions and a very low quiescent current in standby
mode opens a wide range of applications. Automotive qualification gives added value
and enhanced quality for exacting requirements of automotive applications.

3. Functional Description
3.1 Serial Interface
Data transfer starts with the falling edge of the CS signal. Data must appear at DI synchronized
to CLK and is accepted on the falling edge of the CLK signal. LSB (bit 0, SRR) has to be trans-
ferred first. Execution of new input data is enabled on the rising edge of the CS signal. When CS
is high, pin DO is in tri-state condition. This output is enabled on the falling edge of CS. Output
data will change their state with the rising edge of CLK and stay stable until the next rising edge
of CLK appears. LSB (bit 0, TP) is transferred first.

4. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
All values refer to GND pins.
