Description
The Atmel® ATA6836C is a fully protected hex half-bridge driver designed in Smart Power SOI technology, used to control
up to six 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 650mA. The drivers are internally
connected to form six 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.

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 after tdSd 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 Atmel® ATA6836C:
● 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).

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 VCC:
Electrolytic capacitor C > 10µF in parallel with a ceramic capacitor C = 100nF.
●
To reduce thermal resistance, place cooling areas on the PCB as close as possible to GND pins and to the die paddle
in QFN24.
●
Only for the QFN24 versions: The sense pins OUTx SENSE can either be left open or can be connected to the
adjacent OUTx pin. Never use the sense pins OUTx SENSE as power outputs.
Recommended value for capacitors at VS:
Electrolytic capacitor C > 22µF in parallel with a ceramic capacitor C = 100nF.
Value for electrolytic capacitor depends on external loads, conducted interferences and reverse-conducting current
IHSX (see Section 4. “Absolute Maximum Ratings” on page 10).
