1. Description
The T6816 is a fully protected driver interface designed in 0.8 µm BCDMOS technol-
ogy. It is especially suitable for truck or bus applications and the industrial 24-V
www.DataSheet4U.com

supply. It controls up to 12 different loads via a 16-bit dataword.


Each of the six high-side and six low-side drivers is capable to drive currents up to
600 mA. The drivers are freely configurable 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 is also designed to easily build
H-bridges to drive DC motors in motion-control applications.
Protection is guaranteed in terms of short-circuit conditions, overtemperature and
undervoltage. Various diagnosis functions and a very low quiescent current in standby
mode open a wide range of applications.
Automotive qualification referring to conducted interferences, EMC protection and
2 kV ESD protection gives added value and enhanced quality for the exacting require-
ments 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 are 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.

3.2 Power Supply Fail
In case of undervoltage at pin VS, an internal timer is started. When the undervoltage delay time
(tdUV) programmed by the SCT bit is reached, the power supply fail bit (PSF) in the output regis-
ter 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 condi-
tion), 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 with-
out 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-cir-
cuit 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 T6816:
1. Set bit SI in the input register to zero
2. Switch pin 17 (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 or by pin 17 (INH) switched back to 5V.

10.1 Application Notes


It is strongly recommended to connect the blocking capacitors at VCC and VS as close as possi-
ble to the power supply and GND pins.
Recommended value for capacitors at VS:
electrolythic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. Value for elec-
trolytic capacitor depends on external loads, conducted interferences and reverse conducting
current IHSX (see: Absolute Maximum Ratings).
Recommended value for capacitors at VCC:
electrolythic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF.
To reduce thermal resistance it is recommended to place cooling areas on the PCB as close as
possible to GND pins.
