MC33689: System Basis Chip with LIN

Overview

The NXP^® MC33689 is a serial peripheral interface (SPI) controlled system basis chip that combines frequently used functions in an MCU-based system with a LIN transceiver. Applications include power window, mirror, and seat controls.

5.0 V, 50 mA low dropout regulator with full protection and reporting features
Full SPI readable diagnostics and a selectable timing watchdog for detecting errant operation
Three operational modes: Normal (all functions available), Sleep (VDD OFF, wake-up via LIN bus or wake-up inputs), and Stop (VDD ON, wake-up via MCU, LIN bus, or wake-up inputs)

Features

Full-duplex SPI Interface at frequencies up to 4.0 MHz

LIN transceiver capable to 100 kbps with waveshaping capability

5.0 V low dropout regulator with full fault detection and protection

One 50 mA and two 150 mA protected high side switches

Current sense operational amplifier

Compatible with LIN 2.0 specification package
