The MC33689 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.
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.
