MC33742DWR2中文资料摩托罗拉数据手册PDF规格书

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.
