System Basis Chip with LIN
Transceiver
33689D
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)
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
