V2.5, 2004-may-25
2.4.1
Status-Flag (SF) Mode (DMS = GND)
2.4.1.1
SF output
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
VS
– Short circuit of OUT1 or OUT2 against
VS or GND
– Short circuit between OUT1 and OUT2
– Over-current
– Over-temperature
When EN or DIS disables the output stages, status flag SF is pulled low.
2.4.1.2
Fault storage and reset
– In case of Under-Voltage, the failure is not latched. As soon as
VS falls below the
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
VS in the voltage range below the
detection threshold (typical 4.2V) down to 2.5V.
– In the SF-mode, all internal circuitry is supplied by the voltage on
VS. For that reason,
a loss of
VS supply voltage leads to a reset of all stored information (Power-ON-
Reset). This Power-ON-Reset occurs as soon as under-Voltage is detected on
VS
– In case of short circuit, over-current or over-temperature, the fault will be stored.
The output stage remains in tristate and the status-flag at low-level until the error is
reset by one of the following conditions: H -> L on DIS, L -> H on EN or Power-ON
Reset.
2.4.2
SPI-Mode (DMS = 5V)
2.4.2.1
SPI-Interface
The serial SPI interface establishes a communication link between TLE 7209R and the
systems microcontroller. The TLE 7209R 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 7209R 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.
