Freescale Semiconductor Technical Data Document Number: MC33689 Rev.
8.
0, 9/2012 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 SPIreadable 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.
