Product details
Overview
TLE92633QXXUMA1 from Infineon Technologies is a 3-channel high-side smart power switch IC for 12 V automotive body electronics, featuring overcurrent protection, thermal shutdown, and diagnostic feedback via SPI interface, with ±1% current sense accuracy and 5.5–28 V operating supply range. It drives resistive, inductive, and capacitive loads in door modules, seat control units, and lighting systems.
For engineers reviewing the TLE92633QXXUMA1 datasheet, TLE92633QXXUMA1 pinout, TLE92633QXXUMA1 application, or TLE92633QXXUMA1 equivalent, key selection criteria include channel independence, integrated current sensing resolution, SPI fault reporting latency, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
The TLE92633QXXUMA1 integrates three independent high-side drivers with embedded current-sense amplifiers, each capable of delivering up to 600 mA continuous load current. Its SPI interface supports 16-bit readback of real-time channel status, overtemperature flags, open-load detection, and overcurrent event counters.
Internal diagnostics include cycle-by-cycle current limiting (1.8 A peak), junction temperature monitoring (TJ = -40 °C to +150 °C), and configurable blanking time for inductive load switching. The device operates in standalone mode or under microcontroller supervision via dedicated CS/CLK/MOSI/MISO lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 independent high-side switches with individual enable and status reporting |
| Supply Voltage Range | 5.5 V to 28 V - supports cold-crank (6.0 V) and load-dump (40 V transient tolerant) conditions |
| Max Continuous Current | 600 mA per channel - enables direct drive of small solenoids, LEDs, and relays without external heatsinking |
| Current Sense Accuracy | ±1% at 25 °C - allows precise load monitoring and predictive failure analysis in safety-critical nodes |
| SPI Interface Speed | Up to 2 MHz - ensures sub-5 µs fault reporting latency for ASIL-B compliant systems |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and passenger compartment mounting |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side smart switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE92623QXXUMA1 | 2-channel version with identical specs; lacks third channel and associated SPI registers | Suitable only for dual-load nodes; requires firmware revision to remove channel 3 access | Select when system load count is fixed at two and PCB area must be minimized |
| BTS724G | Single-channel, no integrated current sense; relies on external shunt and ADC | Requires additional analog signal chain and MCU resources for diagnostics | Prefer where cost-per-channel is prioritized over diagnostic depth and board space |
Compared with TLE92623QXXUMA1, the TLE92633QXXUMA1 adds scalable channel count and unified SPI register map; versus BTS724G, it delivers full diagnostic autonomy and reduces system-level component count by ≥5 per channel.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TLE92633QXXUMA1 supports continuous operation up to 150 °C junction temperature, with thermal shutdown activating at 175 °C. Derating begins at 125 °C ambient for 600 mA per channel; full-rated current is maintained up to 105 °C ambient with proper PCB copper area (≥200 mm² per channel under thermal pad).
Does the device support daisy-chained SPI communication?
Yes - the TLE92633QXXUMA1 supports true daisy-chain configuration using a single CS line and shared CLK/MOSI/MISO. Each device shifts out its 16-bit status word before passing data to the next, enabling up to 8 devices on one SPI bus without address decoding logic.
Can OUT pins be paralleled to increase current capacity?
No - the outputs are not internally matched for current sharing and lack synchronization circuitry. Paralleling OUT1/OUT2/OUT3 causes uneven current distribution and potential thermal runaway; use a single channel per load or select higher-current alternatives like TLE92663.
Is an external watchdog timer required for functional safety compliance?
No - the device includes an internal window watchdog with programmable timeout (1.6–128 ms) that monitors SPI activity and resets the internal state machine if communication stalls, satisfying ASIL-B diagnostic coverage requirements without external components.
