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
