The NXP® MC33742 is a monolithic integrated circuit combining many functions frequently used by automotive environmental control units (ECUs).
- Fully protected fixed 5.0 V low-drop regulator with current limit, overtemperature pre-warning, and reset
- Output drive with sense input is also provided to implement a second 5.0 V regulator using an external PNP bipolar junction transistor
- 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
