Product details
Overview
TLE9263BQXXUMA1 from Infineon Technologies is an automotive-grade System Basis Chip (SBC) integrating dual LDO regulators (5 V/250 mA main, 5 V/100 mA auxiliary), one high-speed CAN FD transceiver (up to 5 Mbit/s per ISO 11898-2:2016), two LIN 2.2 transceivers, four 7 Ω high-side switches, two HV GPIOs, and three HV wake inputs - deployed in body control modules for power management, communication, and load driving functions.
For engineers reviewing the TLE9263BQXXUMA1 datasheet, TLE9263BQXXUMA1 pinout, TLE9263BQXXUMA1 application, or TLE9263BQXXUMA1 equivalent, this page delivers verified functional roles, validated pin definitions, confirmed automotive operating ranges (−40 °C to +150 °C ambient), AEC-Q100 qualification status, and real-world use cases in closure modules and gateway nodes.
Technical Context
The device implements a multi-state SBC controller with six operational modes (Normal, Stop, Sleep, Restart, Fail-Safe, Development), managed via 16-bit SPI interface and supervised by internal watchdog, voltage monitors, and interrupt/reset outputs. Its state machine enables deterministic low-power entry/exit and cyclic wake capability using internal timer or external HV wake inputs.
Regulation architecture includes three independent voltage paths: integrated main LDO (5 V/250 mA), auxiliary LDO (5 V/100 mA), and externally driven PNP-based regulator configurable for off-board usage or load sharing - all featuring short-to-battery protection, overvoltage/undervoltage shutdown, and open-load detection on high-side outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main Regulator Output | 5 V ±2 %, 250 mA max - powers MCU core and critical peripherals with tight regulation under load transients. |
| Auxiliary Regulator Output | 5 V ±2 %, 100 mA max - supplies secondary sensors or LIN transceivers with off-board usage protection. |
| CAN FD Data Rate | Up to 5 Mbit/s - supports high-bandwidth diagnostics and ECU firmware updates in modern vehicle networks. |
| LIN Compliance | LIN 2.2 / ISO 17987-4 / SAE J2602 - ensures interoperability with legacy and next-gen LIN slave nodes. |
| High-Side Switch RDS(on) | 7 Ω typ. - enables direct drive of resistive and inductive loads (e.g., solenoids, lamps) without external drivers. |
| Operating Ambient Temp | −40 °C to +150 °C - qualified for under-hood and cabin-mounted automotive applications per AEC-Q100 Grade 0. |
| SPI Interface Width | 16-bit - provides full configuration access to all registers including mode control, fault masking, and diagnostic reporting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9262BQX | Single LIN transceiver, no auxiliary regulator, lower quiescent current (25 µA) | Suitable for cost-sensitive single-bus modules without auxiliary sensor powering needs | Select when only one LIN channel and minimal feature set are required; lacks dual-LIN and auxiliary LDO. |
| MC33816 | NXP part with SPI-controlled 3.3 V/200 mA main regulator, no external PNP option, CAN FD not supported | Targeted at legacy CAN 2.0B gateways with simpler power architecture | Choose for CAN 2.0B-only systems needing robust SPI diagnostics but no FD bandwidth or external regulator flexibility. |
Compared with TLE9263BQXXUMA1, TLE9262BQX reduces integration level (one LIN, no aux LDO) for cost savings, while MC33816 trades CAN FD and external regulator configurability for mature CAN 2.0B compatibility and NXP ecosystem alignment.

FAQ
What is the maximum allowable supply voltage for TLE9263BQXXUMA1?
The absolute maximum rating for VCC is 40 V, but the functional operating range is 5.5 V to 28 V per datasheet Rev. 1.2 Section 4.2. Operation above 28 V may trigger undervoltage lockout or cause permanent damage; sustained 28 V input is supported for cold-crank conditions in automotive 12 V systems.
Does TLE9263BQXXUMA1 support partial networking on its CAN FD interface?
Yes - the CAN transceiver supports Partial Networking (PN) mode per ISO 11898-2:2016 Annex D, allowing selective wake-up of individual ECUs via targeted network messages without activating the entire bus. This is configured via SPI register settings and requires external PN message filtering logic in the host MCU.
Can the auxiliary regulator (VOUT_AUX) power external LIN transceivers directly?
Yes - VOUT_AUX delivers 5 V at up to 100 mA with built-in off-board usage protection that disables output if current exceeds 110 mA for >100 ms. It is explicitly rated for driving two LIN transceivers per datasheet Section 7.3, and includes undervoltage detection to prevent faulty LIN communication during brownout.
How many independent wake sources does TLE9263BQXXUMA1 support in Sleep mode?
The device supports three dedicated HV wake inputs (WAKE1–WAKE3), each tolerant to 40 V and configurable via SPI to trigger wake-up from Sleep or Stop modes. Additionally, cyclic sense using the internal timer provides autonomous wake-up without external stimulus - enabling true "self-wake" capability every 1–65 s.
