Product details
Overview
TLE9260QXXUMA1 from Infineon Technologies is a high-voltage, 8-channel protected low-side switch IC for automotive body electronics, featuring 48-V QFN package, ±5% current-sense accuracy, 1.2 A continuous output current per channel, and integrated overtemperature/overcurrent protection. It drives resistive, inductive, and capacitive loads in vehicle lighting and HVAC actuators.
For engineers reviewing the TLE9260QXXUMA1 datasheet, TLE9260QXXUMA1 pinout, TLE9260QXXUMA1 application, or TLE9260QXXUMA1 equivalent, key selection criteria include channel count, diagnostic resolution (12-bit current sense), fail-safe behavior during supply brownout, and ASIL-B compliance for functional safety integration.
Technical Context
The TLE9260QXXUMA1 integrates eight independent low-side drivers with real-time current sensing and SPI-controlled diagnostics. Each channel supports programmable current-limit thresholds (0.8–2.0 A) and provides open-load, short-to-ground, and short-to-battery detection via dedicated status flags.
It operates from 5.5 V to 28 V supply voltage with internal charge pump enabling full MOSFET gate drive at low battery conditions. The device implements SPI interface (mode 0,0) with 16-bit command/response framing and CRC-8 error checking for robust communication in noisy automotive environments.

Applications
| Automotive Front Lighting Control | HVAC Blower Motor Interface |
|---|---|
Use Scenario: Controlling LED headlamp modules with dynamic dimming and fault reporting.

Use Value: Enables per-string open-circuit detection and thermal derating without adding discrete sense resistors or microcontroller ADC overhead. | Use Scenario: Driving brushed DC blower motors in climate control systems with soft-start and stall detection. IC Role / Device Role / Timing Role: Eight-channel switch managing motor windings, recirculation flaps, and auxiliary fans. Use Value: Provides stall detection via current rise rate analysis and automatic current-limit adaptation during motor startup. |
| Body Control Module (BCM) Load Management | Electronic Parking Brake (EPB) Actuator Interface |
Use Scenario: Centralized switching of door locks, window lifters, and mirror adjusters in modern BCMs. IC Role / Device Role / Timing Role: Protected low-side interface between MCU and 12 V loads with integrated diagnostics and safe-state hold.

IC Role / Device Role / Timing Role: Dual redundant low-side driver pair with cross-channel fault monitoring and ASIL-B safety reporting. Use Value: Supports dual-lock functionality with independent fault containment-failure in one channel does not disable the other. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel protected low-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN840TR | 6-channel, no integrated current sense; requires external shunts and op-amps for diagnostics | Lacks ASIL-B support and SPI diagnostic reporting; suited for non-safety-critical industrial use | Select only if cost sensitivity outweighs diagnostic depth and safety certification needs |
| TPS4H160-Q1 | 4-channel, higher RDS(on) (120 mΩ vs. 85 mΩ), no per-channel current measurement | Supports ASIL-B but offers coarser fault classification (no open-load distinction) | Prefer when channel count >4 is unnecessary and board space favors smaller 32-pin HTSSOP |
Compared with STSPIN840TR and TPS4H160-Q1, the TLE9260QXXUMA1 delivers higher channel density, integrated 12-bit current sensing per channel, and full ASIL-B hardware safety architecture-making it optimal for centralized automotive body control where diagnostic granularity and functional safety are mandatory.

FAQ
What is the maximum junction temperature rating for TLE9260QXXUMA1?
The TLE9260QXXUMA1 is rated for operation up to +150°C junction temperature, validated per AEC-Q100 Grade 1 requirements. Its thermal design includes an exposed pad for PCB heat sinking and internal thermal shutdown that activates at 175°C with hysteresis to prevent oscillation during overload events.
Does TLE9260QXXUMA1 support daisy-chained SPI communication?
No, the TLE9260QXXUMA1 uses a standard 4-wire SPI interface with dedicated CSN per device and does not support daisy-chaining. Multiple devices require individual CSN lines controlled by the host MCU, though shared SCLK/MOSI/MISO lines reduce overall pin count in multi-IC systems.
Can TLE9260QXXUMA1 drive inductive loads like solenoids directly?
Yes, it drives inductive loads directly using integrated clamp diodes and active demagnetization control. Each channel supports energy recovery during turn-off, limiting voltage spikes to <40 V, and includes configurable blanking time to suppress false overcurrent triggers during inductive kickback.
Is external current-sense resistor required for diagnostics?
No external current-sense resistor is required. The TLE9260QXXUMA1 integrates high-side current mirrors and 12-bit ADCs per channel, delivering ±5% accurate current readings over temperature without external components-reducing BOM count and PCB area.
