2.4.1.1
In SF-mode, pin 2 is used as an open-drain output status-flag. The pin has to be pulled
to the logic supply voltage with a pull-up resistor, 47 kOhm recommended.
In case of any failure that leads to a shut-down of the outputs, the status-flag is set (e.g.
SF pin pulled to low). These failures are:
– Under Voltage on
– Short circuit of OUT1 or OUT2 against
– Short circuit between OUT1 and OUT2
– Over-current
– Over-temperature
SF is also pulled low when the outputs are disabled by EN or DIS.
2.4.1.2
– In case of under-Voltage, the failure is not latched. As soon as
– In the SF-mode, all internal circuitry is supplied by the voltage on
– In case of short circuit, over-current or over-temperature, the fault will be stored.

2.4.2.1
The serial SPI interface establishes a communication link between TLE 7209-2R and the
systems microcontroller. The TLE 7209-2R always operates in slave mode whereas the
controller provides the master function. The maximum baud rate is 2 MBaud (200pF on
SDO).
By applying an active slave select signal at CSN the TLE 7209-2R is selected by the SPI
master. SDI is the data input (Slave In), SDO the data output (Slave Out). Via SCK
(Serial Clock Input) the SPI clock is provided by the master. In case of inactive slave
select signal (High) the data output SDO goes into tristate.
Final Datasheet
under-Voltage detection threshold, the output stage switches in tristate and the status-
flag is set from high level to low-level. If the voltage has risen above the specified value
again, the output stage switches on again and the status-flag is reset to high-level.
The Under Voltage failure is shown at the SF pin for
detection threshold (typical 4.2V) down to 2.5V.

The output stage remains in tristate and the status-flag at low-level until the error is
