System Basis Chip with Low
Speed Fault Tolerant CAN
Interface
33889
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 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
• 150 mA output current capability for HS1 VBAT switch allowing
drive of external switches pull-up resistors or relays
• Pb-Free Packaging Designated by Suffix Code EG
