Circuit Description
The TLE 6263 is a monolithic IC, which incorporates a failure tolerant low speed CAN-
transceiver for differential mode data transmission, a low dropout voltage regulator for
internal and external 5V supply as well as a SPI (serial peripheral interface) to control
and monitor the IC. Further there are integrated a high side switch, two wake-up inputs,
a window watchdog circuit with fail safe output as well as a reset circuit and early warning
function.
Figure 2
shows a schematic block diagram of the TLE 6263.
Table 1
shows
the status of the different chip features during the four main operation modes.
1)
at low V
CC
output current only active when watchdog undercurrent function is not activated
2)
can only be monitored in V
bat
-stand-by mode via SPI
3)
no wake-up interrupt generated, logic level status monitored via SPI
4)
only active when selected via SPI
5)
if watchdog under-current function active, than FSO = low
