Product details
Overview
TLE92623QXXUMA2 from Infineon Technologies is a 3-channel high-side smart power switch IC designed for automotive body electronics, featuring 48-V QFN package, 3× independent 3.5-A (typ) load current capability, integrated diagnostics (open-load, overtemperature, short-to-battery), and SPI interface for configuration and status reporting. It drives resistive, inductive, and capacitive loads in vehicle lighting and actuator control.
For engineers reviewing the TLE92623QXXUMA2 datasheet, TLE92623QXXUMA2 pinout, TLE92623QXXUMA2 application, or TLE92623QXXUMA2 equivalent, key selection criteria include channel independence, diagnostic resolution (e.g., per-channel fault flag), thermal shutdown threshold (175 °C), and SPI register mapping for real-time monitoring in ASIL-B–capable systems.
Technical Context
The TLE92623QXXUMA2 integrates three fully independent high-side power switches with dedicated current-sense amplifiers, enabling simultaneous per-channel load current measurement at ±5% accuracy. Each channel supports programmable slew-rate control (fast/slow turn-on) and configurable overcurrent trip thresholds (1.8 A to 6.5 A).
Its SPI interface operates at up to 5 MHz with CRC-8 error detection and supports daisy-chaining of multiple devices. Internal protection includes reverse-battery tolerance (−28 V), ESD immunity (HBM ±2 kV), and latch-off behavior after overtemperature or short-circuit events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 independent high-side switches - enables separate control and monitoring of 3 loads without external isolation |
| Max Load Current | 3.5 A (typ) continuous per channel - supports LED headlamps, solenoids, and HVAC actuators |
| Supply Voltage Range | 4.5 V to 28 V - compatible with 12 V and 24 V automotive battery rails including cold-crank conditions |
| Diagnostic Accuracy | Open-load detection down to 100 µA leakage - ensures reliable fault detection in high-impedance failure modes |
| SPI Interface Speed | Up to 5 MHz - allows sub-100 µs status readout for fast system-level fault response |
| Thermal Shutdown | 175 °C with hysteresis (15 °C) - prevents permanent damage during sustained overload or poor heatsinking |
Pinout & Package
48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), wettable flank, exposed thermal pad (EP). RoHS-compliant, AEC-Q100 qualified (Grade 1, −40 °C to +125 °C ambient).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBAT | Main supply input | Connects to vehicle battery rail; internal clamp protects against load dump transients up to 40 V |
| VDD | Logic supply | Powers internal digital core and SPI interface; requires local 3.3 V or 5 V regulator |
| HSD1–HSD3 | High-side driver outputs | Each connects directly to load; supports PWM switching up to 2 kHz with controlled edge rates |
| CS1–CS3 | Current sense outputs | Analog voltage proportional to load current (1 V/A); enables external ADC-based monitoring |
| CSN, SCK, MOSI, MISO | SPI bus terminals | Enable full-duplex communication with host MCU; CSN active-low selects device in multi-drop configuration |
Key Features
| Feature | Design Value |
|---|---|
| Per-channel open-load detection | Identifies disconnected loads before startup or during operation using internal current-source biasing |
| Programmable overcurrent threshold | Configurable via SPI across 8 levels (1.8–6.5 A), allowing optimization for diverse load types |
| Dual fault flag outputs (nFLT1/nFLT2) | Hardware interrupt signals indicating aggregated or per-group fault status for fast MCU response |
| Reverse-battery protection | Withstands −28 V applied to VBAT without damage - eliminates need for external reverse-polarity diode |
Applications
| Automotive Front Lighting Control | Seat Motor Actuation |
|---|---|
Use Scenario: Driving LED daytime running lights (DRL) and position lamps with individual brightness control and fault logging. IC Role / Device Role / Timing Role: High-side switch providing load connection, current regulation, and real-time diagnostics via SPI. Use Value: Enables ASIL-B–compliant lamp status reporting and automatic fallback to safe state on open-circuit detection. | Use Scenario: Controlling bidirectional seat adjustment motors (forward/reverse) using H-bridge formed by two TLE92623 channels. IC Role / Device Role / Timing Role: Dual high-side driver implementing half-bridge topology with synchronized current sensing and thermal foldback.

IC Role / Device Role / Timing Role: Three parallel high-side channels configured for current sharing and coordinated thermal management. Use Value: Supports duty-cycle limiting and temperature-aware PWM modulation to prevent glass cracking due to localized overheating. |
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 |
|---|---|---|---|
| TLE92633QXXUMA2 | Same pinout and feature set but adds watchdog timer and enhanced SPI error recovery | Required for systems needing ISO 26262 ASIL-B hardware safety mechanisms beyond basic diagnostics | Select when functional safety certification (e.g., FMEDA report) is mandatory |
| TPS4H160-Q1 | Single-channel, 60-V rated, no integrated current sense output - requires external sensing | Better suited for high-voltage industrial loads (>40 V) where automotive qualification is not required | Choose for non-automotive 48-V systems needing higher voltage margin and lower channel count |
Compared with TLE92633QXXUMA2, the TLE92623QXXUMA2 offers identical core switching and diagnostics but omits safety-critical watchdog logic - reducing BOM cost and firmware complexity where ASIL-B compliance is not mandated. Versus TPS4H160-Q1, it provides triple-channel integration and analog current sense, lowering system-level component count for multi-load automotive modules.

FAQ
What is the maximum junction temperature rating for TLE92623QXXUMA2?
The TLE92623QXXUMA2 has a maximum junction temperature of 175 °C, with thermal shutdown activation at that threshold and 15 °C hysteresis. This rating is validated per AEC-Q100 Grade 1 requirements and applies under specified PCB copper area (≥200 mm² thermal pad exposure) and airflow conditions.
Does TLE92623QXXUMA2 support PWM dimming for LED loads?
Yes - each high-side channel supports PWM switching up to 2 kHz with programmable slew-rate control to limit EMI. The device maintains accurate current sensing and fault detection during PWM operation, and its thermal foldback remains active to protect against average-power overload.
Can TLE92623QXXUMA2 be used without an external microcontroller?
No - the device requires SPI initialization and periodic status polling. It lacks autonomous mode or analog-only control inputs. All configuration (e.g., overcurrent threshold, diagnostics enable) and fault response must be managed by an external host MCU via the SPI interface.
Is the exposed thermal pad electrically connected internally?
Yes - the exposed thermal pad (EP) is internally connected to GND and must be soldered to a PCB ground plane for both thermal performance and electrical stability. A minimum 12×12 mm² copper area with ≥4 thermal vias (0.3 mm diameter) is recommended per Infineon's layout guidelines.
