33689D Datasheet | Freescale Semiconductor

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 m A and two 150 m A high side switches with output protection are available to drive inductive or resistive loads. The 150 m A 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 m A and two 150 m A protected high side switches - Current sense operational amplifier - patible with LIN 2.0 specification package SYSTEM BASIS CHIP WITH LIN EW SUFFIX (PB-FREE) 98ARH99137A 32-PIN SOICW ORDERING INFORMATION Device (Add R2 Suffix for Tape and Reel) Temperature Range (TA) Package MC33689DPEW -40 °C to 125 °C 32 SOICW VDD VPWR VS1 HS3 VS2 5.0 V L1 L2 HS1 MCU SCK MOSI SCLK...
