All rights reserved. System Basis Chip with LIN Transceiver 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. 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 Full Fault Detection and Protection • One 50 mA and Two 150 mA Protected High-Side Switches • Current Sense Operational Amplifier • The 33689 is compatible with LIN 2.0 Specification Package. • Pb-Free Packaging Designated by Suffix Code EW Figure 1. 33689 Simplified Application Diagram SYSTEM BASIS CHIP WITH LIN 33689D ORDERING INFORMATION Device Temperature Range (TA) Package MC33689DDWB/R2 -40°C to 125°C 32 SOICW MCZ33689DEW/R2 DWB SUFFIX EW SUFFIX (PB-FREE) 98ARH99137A 32-PIN SOICW VPWR SPI MOSI SCK MISO 5.0 V MCU 33689 BUS VS1 VS2 VDD HS3 L1 L2 HS1 HS2 E+ LIN INT RST MOSI SCLK MISO TXD RXD OUT GND IN CS CS WDC E- TGND AGND VDD VCC |
