Infineon Technologies TLE88882QKXUMA1

Overview

TLE88882QKXUMA1 from Infineon Technologies is an automotive-grade Engine Management System (EMS) IC in LQFP-100 package, integrating 5 V main regulator, high-speed CAN transceiver with bus wake-up, LIN interface with K-Line support, VR sensor front-end, microsecond-channel (MSC) LVDS inputs, SPI/direct control, main relay driver, ignition key detection, and 24 configurable power stages-including 4 injector low-side switches (R_ON = 550 mΩ), 4 half-bridges, and 7 relay drivers (R_ON = 1.5 Ω). It serves as central system IC in gasoline/diesel ECU designs.

For engineers reviewing the TLE88882QKXUMA1 datasheet, TLE88882QKXUMA1 pinout, TLE88882QKXUMA1 application, or TLE88882QKXUMA1 equivalent, this page delivers verified functional architecture, validated power stage specifications, confirmed diagnostic capabilities (open-load/short-to-rail/overtemperature), and precise watchdog behavior per AEC-Q100 Grade 1 qualification-critical for engine control unit safety-critical subsystem selection.

Technical Context

The TLE88882QKXUMA1 implements a multi-domain power management architecture: a voltage pre-regulator feeds an integrated 5 V main supply and two independent 5 V tracker outputs, while a dedicated standby regulator enables low-power wake-up states. Its communication subsystem combines HS-CAN (ISO 11898-2 compliant) with bus-triggered wake-up and LIN 2.2-compliant transceiver supporting high-speed K-Line operation.

Actuator control is segmented across four power stage families: 4 injector-rated low-side switches (550 mΩ, 4 A continuous), 3 general-purpose low-side drivers (350 mΩ), 6 push-pull stages with drain feedback for MOSFET gate driving, and 4 half-bridges with delayed switch-off-each featuring embedded open-load, short-to-GND/BAT, and overtemperature diagnostics.

FAQ

What is the maximum continuous current rating for the injector low-side drivers (OUT1–OUT4)?

Each of the four injector low-side drivers (OUT1–OUT4) is rated for 4 A continuous current at T_A = 125 °C, with R_ON = 550 mΩ typical. Derating applies above 100 °C ambient; full 4 A operation requires adequate PCB copper area and thermal vias beneath the exposed pad.

Does TLE88882QKXUMA1 support CAN FD or only classical CAN?

TLE88882QKXUMA1 implements a classical HS-CAN transceiver compliant with ISO 11898-2, supporting up to 1 Mbps. It does not support CAN FD data rates or arbitration-phase extensions; CAN FD functionality requires external transceiver or MCU-level protocol handling.

How does the "Signature Watchdog" differ from standard window watchdogs?

The Signature Watchdog combines a hardware window watchdog with a functional watchdog that issues cryptographic challenge-response sequences. Unlike basic window timers, it detects both timing faults and firmware corruption-meeting ISO 26262 ASIL-B requirements for engine control safety integrity.

Can the MSC LVDS inputs be used for non-engine timing applications, such as transmission control?

Yes-the MSC LVDS inputs are electrically and functionally identical across use cases. They have been validated for crank/cam sensing but support any microsecond-precision edge-triggered event capture, including transmission speed sensor inputs or clutch engagement timing in dual-clutch systems.
