Product details
Overview
TLE92623BQXXUMA2 from Infineon Technologies is a mid-range+ System Basis Chip (SBC) integrating dual LDO regulators (5 V/250 mA main, 5 V/100 mA auxiliary), a high-speed CAN FD transceiver (up to 5 Mbit/s, ISO 11898-2:2016 compliant), LIN 2.2 transceiver, four 7 Ω high-side switches, two HV GPIOs, three HV wake inputs, and 16-bit SPI for configuration/diagnostics - deployed in automotive body control modules requiring integrated power, communication, and I/O supervision.
For engineers reviewing the TLE92623BQXXUMA2 datasheet, TLE92623BQXXUMA2 pinout, TLE92623BQXXUMA2 application, or TLE92623BQXXUMA2 equivalent, key selection criteria include CAN FD partial networking support, off-board regulator configurability via external PNP, fail-safe watchdog behavior, thermal shutdown thresholds, and AEC-Q100 qualification for 125 °C ambient operation.
Technical Context
The TLE92623BQXXUMA2 implements a multi-state SBC architecture with six operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe), each governed by internal state machine logic and configurable via SPI. Wake-up is supported through cyclic sense, internal timer, and three dedicated HV wake inputs with programmable sensitivity.
Its CAN FD transceiver operates in Partial Networking mode with selective wake (SWK) capability, enabling targeted node activation via WUP/WUF frames while maintaining bus silence detection (CANSIL) and protocol error counter monitoring. The LIN transceiver complies fully with ISO 17987-4 and SAE J2602, supporting auto-baud and slave node response timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MC33903 | Single 5 V/250 mA regulator; no auxiliary LDO; LIN only (no CAN FD); 3 HS switches | Lacks CAN FD and partial networking - suitable for cost-sensitive LIN-only nodes without gateway function | Select when CAN FD and dual-regulator redundancy are not required; lower pin count and package size |
| Renesas ISL78322 | Dual 3.3 V/200 mA regulators; no integrated CAN/LIN; requires external transceivers; 4 HS switches | Requires external CAN FD and LIN transceivers - increases BOM and layout complexity | Choose when strict 3.3 V system biasing is mandatory and communication interfaces are already centralized elsewhere |
Compared with MC33903 and ISL78322, TLE92623BQXXUMA2 uniquely combines CAN FD partial networking, dual LDOs with off-board protection, and HV wake inputs in a single AEC-Q100-qualified package - making it optimal for integrated body domain gateways where space, power efficiency, and network intelligence are jointly constrained.

FAQ
What is the maximum allowable input voltage for VCC?
The absolute maximum rating for VCC is 40 V, but the functional operating range is 5.5 V to 28 V per the datasheet Rev. 1.2. Operation above 28 V may trigger overvoltage protection and force shutdown; sustained exposure beyond 40 V risks permanent damage to internal regulators and transceivers.
Does TLE92623BQXXUMA2 support CAN FD Classic fallback mode?
Yes - the integrated CAN transceiver supports CAN FD tolerant mode per ISO 11898-2:2016, allowing seamless interoperability with legacy CAN 2.0B nodes on the same bus without reconfiguration. It automatically detects bit timing and frame format, enabling mixed-network deployment.
How is fail-safe behavior triggered and what outputs are asserted?
Fail-safe mode activates upon critical faults including VCC undervoltage, regulator overtemperature (>165 °C), watchdog timeout, or SPI configuration error. In this mode, all high-side switches are forced OFF, VREG1/VREG2 enter low-power hold, and dedicated FS_OUT pin asserts low while RESET remains active - ensuring deterministic safe state.
Can the auxiliary regulator (VREG2) be used to power external CAN or LIN transceivers?
Yes - VREG2 is explicitly designed for off-board usage, including powering external CAN/LIN transceivers, provided the total load remains ≤100 mA and the external circuit includes reverse-polarity and overvoltage protection. Its built-in off-board usage lockout prevents backfeed if VREG2 is externally driven.
