Final Data TLE 6262 G
1.5 Circuit Description
The TLE 6262 G 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 interface to control and monitor the IC.
Further there are integrated three high side switches, two low side switches, a window
watchdog circuit and a reset circuit. Both, the window watchdog and reset function are
referring to a time base that is programmable via an external resistor.
Figure 2 shows a block schematic diagram of the TLE 6262 G

1) _{at low VCC output current only active when watchdog undercurrent function is not activated}
2) _{a bus wake-up is monitored by setting the RxD output low}
3) _{only active when selected via SPI}
4) _{also active when driven via the PWM input}
5) _{automatically disabled when a reset occurs}
6) _{automatically disabled when a reset or watchdog reset respectively, occurs or the watchdog is disabled}
