PIN CONFIGURATION
FUNCTIONAL DESCRIPTION
The Si9243AEY can be either in transmit or receive mode
and it contains over temperature, and short circuit VBAT fault
detection circuits.
The voltage on the K and L pins are internally compared to
VBAT/2. If the voltage on the K or L pin is less than VBAT/2 then
RXK or RXL output will be "low". If the voltage on the K or L
pin is greater than VBAT/2 then RXK or RXL output will be
"high".
In order to be in transmit mode, TX must be set "low". The TX
signal is then internally inverted and turns the MOSFET on,
causing the K pin to be "low". In transmit mode, the
processor monitors the RXK and TX. When the two mirror
each other there is no fault. In the event of over temperature,
or short circuit to VBAT, the Si9243AEY will turn off the K
output to protect the IC. The K pin will stay in high impedance
and RXK will follow the K pin. The fault will be reset when TX
is toggled high. RXK, RXL and TX pins have internal pull up
resistor to VDD while K and L pins have internal pull down
resistors. When any one of the TX, VBAT or GND pins is open
the K output is off.
When the TX pin is set "high" the Si9243AEY is in receive
mode and the internal MOSFET is turned off. RXL and RXK
outputs will follow L and K inputs respectively.
