PIN CONFIGURATION
FUNCTIONAL DESCRIPTION
The Si9241AEY can be either in transmit or receive mode
and it contains over temperature, and short circuit VBAT fault
detection circuits.
The voltage on K is internally compared to VBAT/2. If the
voltage on the K pin is less than VBAT/2 then RX output will
be "low". If the voltage on the K pin is greater than VBAT/2
then RX output will be "high".
In order to be in transmit mode, CS must be set "low". When
CS and TX are set "low" the internal MOSFET will turn on,
causing the K pin to be "low". In the transmit mode, the
processor monitors RX and TX. When the two mirror each
other there is no fault. In the event of over temperature, or
short circuit to VBAT, the Si9241AEY will turn off the K output
to protect the IC and the external open drain FAULT pin will
be asserted. The K pin will stay in high impedance and RX
will follow the K pin. The fault will be reset when CS is toggled
high. RX, CS and TX pins have an internal pull up resistor to
VDD while the K pin has internal pull down resistors. When
any one of the TX, VBAT or GND pins is open the K output is
off.
When CS is set "high" the Si9241AEY is in receive mode and
the internal MOSFET for the K pin is turned off. The RX
output will follow the K pin. If CS is "low" while the IC is
receiving data, an incorrect fault signal will occur.
To inhibit the short detect, tie CS and TX together.
