5.1
The TLE8209-2SA has three different supply pins: VDD, VS and VDDIO. VDD is used to supply the internal logic
circuitry. VS connects to battery voltage and supplies the output stages. The voltage at pin VDDIO defines the high
level output voltage at the pin SO of the SPI interface. VDDIO is also used as a mode select pin. If VDDIO is
connected to ground, the device is set to status flag mode (SPI inactive).
On power up the device will enter a functional state when V
In this state all output stages are inactive and internal registers are cleared. When V

state of VDD monitoring is stored in STATCON_REG and can be read out via SPI.
The output stages can also be turned off by pulling the ABE pin to ground externally.
In case of VDD failure, the output stages are switched off, even if the pin ABE should be connected to a high level
signal because of external short circuit to VDD or battery voltage (up to 18V). OUT1 and OUT2 cannot be switched
on in over- or undervoltage condition, switching off is always possible. A power on reset (V

Control of VDD-monitoring is possible in SPI mode only. Detailed information (differentiation of over and under-
voltage detection) is only possible by SPI interface.
Behavior of VDD monitoring in SF mode:
- monitoring is present with the specified values for over- and undervoltage
- any test of over- and undervoltage threshold is not possible
- the latch for overvoltage is disabled
VDD Undervoltage
If the VDD voltage is lower than the supply voltage supervisory lower threshold (V

valid, writing new information to configuration registers is possible as far as they are not reset by ABE. If VDD falls

CONFIG0=’1’: ABE is latched and outputs remain off after overvoltage. Return to normal operation is only possible
with power-on reset or by changing this bit via SPI.
