Freescale Semiconductor

Technical Data

System Basis Chip with Low

Speed Fault Tolerant CAN

Interface

33889

An SBC device is a monolithic I^Ccombining 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.

SYSTEM BASIS CHIP

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.

28-PIN SOICW

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
