Product details
Overview
TLE95623QXJXUMA1 from Infineon Technologies is a 3-channel high-side smart power switch IC for automotive body electronics, featuring 12 V nominal supply operation, integrated current sense (±5% accuracy), overtemperature shutdown, and diagnostic feedback via SPI interface. It drives resistive and inductive loads up to 5 A per channel in 12 V battery systems.
For engineers reviewing the TLE95623QXJXUMA1 datasheet, TLE95623QXJXUMA1 pinout, TLE95623QXJXUMA1 application, or TLE95623QXJXUMA1 equivalent, key selection criteria include channel count, current rating per channel, SPI diagnostic capability, thermal shutdown behavior, and AEC-Q100 Grade 1 qualification for under-hood use.
Technical Context
This device integrates three independent high-side power switches with embedded protection logic, each controlled via dedicated SPI registers. It operates across −40 °C to +150 °C ambient temperature and supports PWM switching up to 100 Hz with <1.5 µs propagation delay.
The SPI interface uses a 4-wire synchronous protocol (CSN, SCLK, MOSI, MISO) at up to 10 MHz clock rate and provides real-time status reporting including open-load detection, short-to-battery, short-to-ground, and overtemperature flags per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 28 V - supports cold-crank (5.5 V) and load-dump (28 V) conditions in 12 V automotive systems |
| Max Output Current per Channel | 5 A continuous - enables direct driving of lamps, solenoids, and small motors without external heatsinking |
| Current Sense Accuracy | ±5% over −40 °C to +150 °C - allows precise load monitoring and fault classification without calibration |
| SPI Interface Speed | Up to 10 MHz - permits fast configuration and status polling in real-time control loops |
| Propagation Delay | Typ. 1.2 µs - ensures tight timing alignment between command and output switching in safety-critical sequences |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C junction) - qualified for engine compartment and front-end module applications |
Pinout & Package
Package: PG-VQFN-48-19 (4.5 mm × 5.5 mm, 0.4 mm pitch, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V battery rail; internal clamping protects against load dump transients |
| VDD | Digital supply input | Supplies internal logic and SPI interface; requires local 3.3 V regulation |
| CSN | SPI chip select | Active-low signal enabling SPI communication; supports daisy-chaining multiple devices |
| MOSI/MISO/SCLK | SPI data/control lines | Full-duplex serial interface for register read/write and diagnostic status retrieval |
| OUT1–OUT3 | High-side output terminals | Each drives external load to battery; includes integrated current sense and protection circuitry |
| ISx (x=1–3) | Analog current sense outputs | Provides voltage-proportional analog signals for external ADC monitoring of load current |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent high-side switches | Enables consolidated control of three separate loads (e.g., headlight low-beam, fog lamp, cooling fan) with shared diagnostics |
| Integrated current sensing per channel | Eliminates need for external shunt resistors and amplifiers, reducing BOM count and PCB area |
| Short-to-battery and short-to-ground detection | Identifies wiring faults before fuse blow-out, supporting predictive maintenance and system-level fault logging |
| Thermal shutdown with auto-restart | Prevents latch-up during overload; resumes operation after die temperature falls below 145 °C threshold |
| SPI-configurable blanking time | Adjusts fault detection window (1–100 µs) to suppress false triggers during inductive turn-off transients |

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 |
|---|---|---|---|
| BTS724G | Single-channel, 40 V max VDS, no integrated current sense output | Lacks per-channel analog current monitor; requires external sensing for closed-loop control | Choose when only basic on/off control is needed and cost-per-channel is prioritized over diagnostics |
| TLE8102SE | Dual-channel, 40 V max VDS, SPI interface, ±8% current sense accuracy | Lower current sense precision and fewer channels limit scalability in multi-load systems | Choose for space-constrained dual-load applications where ±8% tolerance is acceptable |
Compared with BTS724G and TLE8102SE, TLE95623QXJXUMA1 delivers higher channel density, tighter current sense accuracy (±5%), and full 3-channel diagnostic coverage-making it optimal for next-generation BCM and lighting ECUs requiring scalable, ASIL-ready load management.

FAQ
What is the maximum junction temperature for continuous operation?
The TLE95623QXJXUMA1 supports continuous operation up to 150 °C junction temperature. Thermal shutdown activates at 165 °C, and automatic restart occurs after die temperature drops below 145 °C. The exposed thermal pad must be soldered to a minimum 120 mm² copper pour for reliable heat dissipation in 5 A per channel operation.
Does this IC support PWM dimming for LED loads?
Yes, TLE95623QXJXUMA1 supports PWM switching up to 100 Hz with 1.2 µs typical propagation delay and adjustable blanking time (1–100 µs). Its integrated current sense and fast fault detection allow stable closed-loop dimming without external current feedback components.
Can multiple TLE95623QXJXUMA1 devices share one SPI bus?
Yes, multiple TLE95623QXJXUMA1 devices can be daisy-chained on a single SPI bus using individual CSN lines. Each device responds only when its CSN is asserted low, and MISO data is shifted out sequentially, enabling compact wiring and reduced MCU pin count in multi-IC systems.
Is external reverse-battery protection required?
No external reverse-battery protection is required. The device includes integrated reverse-polarity protection that blocks conduction when VBB is below −0.3 V, preventing damage during incorrect battery connection. This feature is active regardless of device power state or SPI configuration.
