MC33889DPEGR2

MC33889DPEGR2 is a system basis chip (SBC) with low speed fault tolerant CAN interface. It is an SBC having a fully protected, fixed 5.0V low drop-out regulator, with current limit, overtemperature prewarning and reset. An SBC device is a monolithic IC combining many functions repeatedly found in standard microcontroller-based systems, e.g., protection, diagnostics, communication, power, etc. An output drive with sense input is also provided to implement a second 5.0V regulator using an external PNP. It has normal, standby, stop and sleep modes, an internally switched high-side power supply output with two wake-up inputs, programmable timeout or window watchdog, interrupt, reset, SPI input control, and a low-speed fault tolerant CAN transceiver, compatible with CAN 2.0A and B protocols for module-to module communications. The combination is an economical solution for power management, high-speed communication, and control in MCU-based systems.
