Overview
MCU
The 33689 is a serial peripheral interface
(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 provides full SPI
readable diagnostics and a selectable
timing watchdog for detecting errant
operation.
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)
