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.

Preliminary
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 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 especially 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.

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 transferred first. Execution of new input data is enabled on the rising edge of the CS signal. When CS
is high, pin DO is in a 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.

3.2
Power-supply Fail
In case of undervoltage at pin VS, an internal timer is started. When during a permanent undervoltage the delay time (tdUV) is reached, the power supply fail bit (PSF) in the output register is
set and all outputs are disabled. When normal voltage is present again, the outputs are enabled
immediately. The PSF bit remains high until it is reset by the SRR bit in the input register.
3.3
Open-load Detection
If the open-load detection bit (OLD) is set to low, a pull-up current for each high-side switch and
a pull-down current for each low-side switch is turned on (open-load detection current IHS1-6,
ILS1-6). If VVS – VHS1-6 or VLS1-6 is lower than the open-load detection threshold (open-load condition), the corresponding bit of the output in the output register is set to high. Switching on an
output stage with OLD bit set to low disables the open load function for this output.
3.4
Overtemperature Protection
If the junction temperature exceeds the thermal prewarning threshold, TjPW set, the temperature
prewarning bit (TP) in the output register is set. When the temperature falls below the thermal
prewarning threshold, TjPW reset, the bit TP is reset. The TP bit can be read without transferring
a complete 16-bit data word: with CS = high to low, the state of TP appears at pin DO. After the
microcontroller has read this information, CS is set high and the data transfer is interrupted without affecting the state of the input and output registers.
If the junction temperature exceeds the thermal shutdown threshold, Tj switch off, the outputs are
disabled and all bits in the output register are set high. The outputs can be enabled again when
the temperature falls below the thermal shutdown threshold, Tj switch on, and when a high has
been written to the SRR bit in the input register. Thermal prewarning and shutdown threshold
have hysteresis.
3.5
Short-circuit Protection
The output currents are limited by a current regulator. Current limitation takes place when the
overcurrent limitation and shutdown threshold (IHS1-6, ILS1-6) are reached. Simultaneously, an
internal timer is started. The shorted output is disabled when during a permanent short the delay
time (tdSd) programmed by the short-circuit timer bit (SCT) is reached. Additionally, the short-circuit detection bit (SCD) is set. If the temperature prewarning bit TP in the output register is set
during a short, the shorted output is disabled immediately and SCD bit is set. By writing a high to
the SRR bit in the input register, the SCD bit is reset and the disabled outputs are enabled.
3.6
Inhibit
There are two ways to inhibit the ATA6836:
• Set bit SI in the input register to 0
• Switch pin INH to 0V
In both cases, all output stages are turned off but the serial interface stays active. The output
stages can be activated again by bit SI = 1 (when INH = VCC) or by pin INH switched back to
VCC (when SI = 1).

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.

Application Notes
• Connect the blocking capacitors at VCC and VS as close as possible to the power supply and
GND pins.
• Recommended value for capacitors at VS:
Electrolytic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. Value for
electrolytic capacitor depends on external loads, conducted interferences and
reverse-conducting current IHSX (see Section 4. “Absolute Maximum Ratings” on page 10).
• Recommended value for capacitors at VCC:
Electrolytic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF.
• To reduce thermal resistance, place cooling areas on the PCB as close as possible to GND
pins and to the die paddle in QFN24.
