Product details
Overview
TLE9263QXXUMA1 from Infineon Technologies is a 3-channel high-side smart power switch with integrated diagnostics, designed for 12 V automotive body control modules. It delivers 600 mA per channel, supports PWM up to 25 kHz, features overtemperature and overcurrent shutdown, and operates across -40 °C to 150 °C ambient. Used in seat motor control, mirror adjustment, and HVAC damper actuation.
For engineers reviewing the TLE9263QXXUMA1 datasheet, TLE9263QXXUMA1 pinout, TLE9263QXXUMA1 application, or TLE9263QXXUMA1 equivalent, key selection criteria include channel count, diagnostic resolution (open-load/short-to-VBAT/short-to-GND), thermal shutdown hysteresis, and SPI register mapping for fault reporting.
Technical Context
The TLE9263QXXUMA1 integrates three independent high-side drivers with current-sense amplifiers and digital SPI interface for real-time status feedback. Each channel includes adaptive slew-rate control and configurable blanking time for noise immunity during load switching.
It implements embedded protection logic including reverse-battery tolerance (−16 V), load-dump survival (40 V), and cyclic redundancy check (CRC) on all SPI transactions. Fault registers report individual channel conditions without requiring external monitoring circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 independent high-side switches - enables compact integration of multiple low-power actuators in single-package BCU designs |
| Max Output Current | 600 mA per channel - sufficient for driving small DC motors, solenoids, and LED arrays without external heatsinking |
| Supply Voltage Range | 4.5 V to 28 V - compatible with 12 V automotive battery systems including cranking and load-dump transients |
| Diagnostic Resolution | Open-load, short-to-VBAT, short-to-GND detection per channel - eliminates need for discrete sense resistors or comparator circuits |
| SPI Interface | 4-wire SPI with CRC - allows daisy-chaining up to 8 devices and ensures robust communication in noisy vehicle environments |
| Thermal Shutdown | 175 °C junction with 15 °C hysteresis - prevents latch-up during sustained overload while enabling automatic recovery after cooling |
Pinout & Package
48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad; RoHS-compliant, AEC-Q100 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main supply input | Connects to 12 V battery rail; internal LDO powers logic and gate drivers |
| GND | Power and signal ground | Common reference for all analog sensing and digital logic; must be low-impedance connection to chassis |
| VS1–VS3 | High-side output terminals | Each drives one load to battery; integrated current sense enables per-channel diagnostics |
| CSN | SPI chip select | Active-low enable for SPI communication; supports multi-device bus sharing |
| MOSI/MISO/SCLK | SPI data/control lines | Full-duplex serial interface with CRC-8 for fault register readback and configuration writes |
| EN | Global enable input | Hardware reset that disables all outputs and clears fault latches upon falling edge |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sense per channel | Enables precise open-load and short-circuit detection without external shunts or op-amps |
| Configurable blanking time | Reduces false fault triggers during PWM turn-on by suppressing transient spikes in current sense path |
| Daisy-chain SPI capability | Supports up to 8 devices on single bus, reducing MCU GPIO usage and PCB routing complexity |
| AEC-Q100 Grade 1 qualification | Validated for operation from −40 °C to +125 °C ambient, meeting automotive reliability requirements |
Applications

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 |
|---|---|---|---|
| ON Semiconductor NCV8460A | Single-channel, no SPI interface; analog fault flag only | Limited to simple on/off loads without diagnostics granularity | Select when cost sensitivity outweighs diagnostic depth and multi-channel integration needs |
| STMicroelectronics VNQ7E100AJ | 4-channel, SPI with enhanced watchdog timer but no per-channel current sense amplifier | Requires external shunt for open-load detection; higher pin count | Prefer when system requires >3 channels and watchdog timeout configurability is critical |
Compared with NCV8460A and VNQ7E100AJ, the TLE9263QXXUMA1 uniquely combines triple-channel integration, per-channel analog current sensing, and SPI-based fault classification-reducing MCU firmware complexity and enabling predictive maintenance in body electronics.

FAQ
What protection features does the TLE9263QXXUMA1 provide?
The device integrates overtemperature shutdown with hysteresis, overcurrent limiting per channel, reverse-battery tolerance down to −16 V, and load-dump survival up to 40 V. It also detects open-load, short-to-VBAT, and short-to-GND faults individually, reporting each via dedicated SPI register bits without external components.
Can the TLE9263QXXUMA1 drive inductive loads like solenoids?
Yes - it is explicitly rated for inductive loads with integrated flyback energy clamping. The internal clamp diode and adaptive slew-rate control suppress voltage spikes during turn-off, supporting solenoid coils with inductance up to 100 mH and energy ratings ≤ 100 mJ per channel.
Is the TLE9263QXXUMA1 compatible with 5 V microcontrollers?
Yes - its SPI interface operates at 3.3 V logic levels but is 5 V tolerant on MOSI, MISO, SCLK, and CSN pins. The EN pin accepts 1.8 V to 5.5 V input, allowing direct interfacing with common automotive MCUs without level-shifting circuitry.
Does the TLE9263QXXUMA1 support functional safety standards?
It meets ISO 26262 ASIL-B requirements at the component level, with built-in self-test (BIST) for analog sense path, CRC-protected SPI, and fault-reporting architecture aligned with FMEDA analysis. Full ASIL-B system integration requires proper MCU-level software handling of reported faults.
