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) CS SCK MOSI MISO SPI CS SCLK MOSI MISO INT RST IN OUT TXD RXD HS3 L1 L2 HS1 HS2 E+ EGND TGND AGND LIN BUS Performance Typical Values Operating Voltage 5.5 V to 27 V Data Rate 10 kbps to 100 kbps Internal 5.0 V Regulator 50 mA Max HS1 and HS2 Protected Current 150 mA Sleep/Stop Current 35/60 µA Ambient Operating Temperature -40 °C ≤ TA ≤ 125 °C Analog, Mixed signal and Power Management Features Ordering Information • Full-duplex SPI interface at frequencies up to 4.0 MHz Device • LIN transceiver capable of up to 100 kbps with waveshaping capability MC33689DPEW • 5.0 V low dropout regulator full fault detection and protection • One 50 mA and two 150 mA protected high side switches (add R2 suffix for tape and reel) Temperature Range Package -40 to 125 °C 32 SOICW Documentation Description MC33689 System Basis Chip with LIN Transceiver SG1002 Analog Product Selector Guide SG187 Automotive Product Selector Guide • Current sense operational amplifier • Additional devices available for comparison in Analog Product Selector Guide - SG1002 and Automotive Product Selector Guide - SG187 Freescale Semiconductor is a leading provider for over 25 years of high performance products that use SMARTMOS technology that combines digital, power andstandard analog functions.The company supplies analog and power management ICs for the automotive, consumer, networking and industrial markets.
