Technical Data

System Basis Chip with LIN

Transceiver

33689D

The 33689 is a SPI-controlled System Basis Chip (SBC) that

combines many frequently used functions in an MCU-based system

plus a Local Interconnect Network (LIN) transceiver. Applications

include power window, mirror, and seat controls. The 33689 has a

5.0 V, 50 mA low dropout regulator with full protection and reporting

features. The device provide full SPI-readable diagnostics and a

selectable timing watchdog for detecting errant operation.

SYSTEM BASIS CHIP WITH LIN

The LIN transceiver waveshaping circuitry can be disabled for

higher data rates. One 50 mA and two 150 mA high-side switches with

output protection are available to drive inductive or resistive loads. The

150 mA switches can be pulse-width modulated (PWM).

Two high-voltage inputs are available for contact monitoring or as

external wake-up inputs. A current sense operational amplifier is

available for load current monitoring.

The 33689 has three operational modes:

• Normal (all functions available)

• Sleep (VDD OFF, wake-up via LIN bus or wake-up inputs)

• Stop (VDD ON, wake-up via MCU, LIN bus, or wake-up inputs)
