System Basis Chip (SBC) with Low Speed Fault Tolerant CAN Interface

The 33889 is an SBC having a fully protected, fixed 5.0 V low drop-out regulator, with current limit, overtemperature pre-warning 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 5.0 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, serial peripheral interfce (SPI) input control, and a low-speed 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 kbps fault tolerant CAN physical interface.
• External high voltage wake-up input, associated with HS1 VBAT switch
• 150mA output current capability for HS1 VBAT switch allowing drive of external switches pull-up resistors or relays
