System Basis Chip (SBC) with
Enhanced High-Speed CAN
Transceiver
The 33742 and the 33742S are monolithic integrated circuits combining
many functions frequently used by automotive environmental control units
(ECUs).
The 33742 is an SBC having a fully protected fixed 5.0 V low-drop regulator
with current limit, overtemperature pre-warning, and reset. An output drive with
sense input is also provided to implement a second 5.0 V regulator, using an
external PNP bipolar junction transistor. The 33742 has normal, standby, stop,
and sleep modes, an internally switched high-side power supply output with
four wake-up inputs, programmable window watchdog, interrupt, reset, SPI
input control, and a high-speed CAN transceiver compatible with CAN 2.0 A
and B protocols for module-to-module communication.
