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 VCC output current only active when watchdog undercurrent function is not activated

2) can only be monitored in Vbat-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
