MCZ33889

www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC33889 Rev. 11.0, 12/2006 System Basis Chip with Low Speed Fault Tolerant CAN Interface An SBC device is a monolithic IC combining many functions repeatedly found in standard microcontroller-based systems, e.g., protection, diagnostics, communication, power, etc. The 33889 is an SBC having fully protected, fixed 5.0 V low drop-out regulator, with current limit, over-temperature 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. The 33889 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 lowspeed fault tolerant CAN transceiver, compatible with CAN 2.0 A 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. Features VDD1: 5.0 V low drop voltage regulator, current limitation, overtemperature detection, monitoring and reset function with total current capability 200 mA V2: tracking function of VDD1 regulator; control circuitry for external bipolar ballast transistor for high flexibility in choice of peripheral voltage and current supply Four operational modes Low standby current consumption in Stop and Sleep modes Built-in low speed 125 ...
