1. Description
The ATA6836 is a fully protected hex half-bridge driver designed in Smart Power SOI
technology, used to control up to 6 different loads by a microcontroller in automotive
and industrial applications.
Each of the six high-side and six low-side drivers is capable of driving currents up to
650 mA. The drivers are internally connected to form 6 half-bridges and can be con-
trolled separately from a standard serial data interface. Therefore, all kinds of loads,
such as bulbs, resistors, capacitors and inductors, can be combined. The IC espe-
cially supports the application of H-bridges to drive DC motors.
Protection is guaranteed in terms of short-circuit conditions, overtemperature and
undervoltage. Various diagnosis functions and a very low quiescent current in standby
mode make a wide range of applications possible.
Automotive qualification referring to conducted interferences, EMC protection and
ESD protection gives added value and enhanced quality for the exacting requirements
of automotive applications.

OUT4
Half-bridge output 4; formed by internally connected power MOS high-side switch 4 and low-side switch 4
with internal reverse diodes; short circuit protection; overtemperature protection; diagnosis for short and
open load
VS Power supply output stages HS4, HS5 and HS6
VS Power supply output stages HS1, HS2 and HS3
OUT3 Output 3; see pin 1
OUT3 SENSE Only for testability in final test
NC Internal bond to GND
OUT2 Output 2; see pin 1
OUT2 SENSE Only for testability in final test
OUT1 SENSE Only for testability in final test
OUT1 Output 1; see pin 1
INH Inhibit input; 5V logic input with internal pull down; low = standby, high = normal operation
Serial data output; 5V CMOS logic level tri-state output for output (status) register data; sends 16-bit status
DO information to the microcontroller (LSB is transferred first). Output will remain tri-stated unless device is
selected by CS = low, therefore, several ICs can operate on one data output line only
VCC Logic supply voltage (5V)
NC Internal bond to GND
GND SENSE Ground; reference potential; internal connection to the lead frame; cooling tab
