Product details
Overview
TLE92633QXXUMA2 from Infineon Technologies is a 3-channel high-side smart power switch IC designed for automotive body electronics, featuring 3× 28 mΩ on-resistance (typ.), ±1% current sense accuracy, and integrated diagnostics including overtemperature, overcurrent, and open-load detection. It operates from 5.5 V to 28 V supply and supports PWM-controlled load driving in 12 V/24 V vehicle electrical systems.
For engineers reviewing the TLE92633QXXUMA2 datasheet, TLE92633QXXUMA2 pinout, TLE92633QXXUMA2 application, or TLE92633QXXUMA2 equivalent, key selection criteria include channel independence, diagnostic reporting via SPI, thermal shutdown threshold of 175 °C, and compliance with AEC-Q100 Grade 1 qualification for under-hood use.
Technical Context
This device integrates three independent high-side switches with current-sense amplifiers, fault flag output, and a 4-wire SPI interface for configuration and status readback. Each channel delivers up to 3.5 A continuous current with active current limiting at 5.5 A (typ.) and supports pulse-width modulation up to 2 kHz.
The IC implements real-time diagnostics: open-load detection in OFF state (via pull-down resistor sensing), short-to-battery detection during ON state, and overtemperature protection with hysteresis. All fault events are latched and reported via dedicated SPI registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 independent high-side switches with individual enable and status reporting |
| RDS(on) (typ.) | 28 mΩ per channel - enables low-power dissipation at 3.5 A load (≤345 mW/channel) |
| Current Sense Accuracy | ±1% - supports precise load monitoring and closed-loop current control |
| Supply Voltage Range | 5.5 V to 28 V - compatible with 12 V and 24 V automotive battery systems |
| Diagnostic Interface | 4-wire SPI (up to 2 MHz) - enables real-time fault register access and configuration |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and front-end module locations |
Pinout & Package
48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad; RoHS-compliant, wettable flank terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBAT | Main power input | Connects to vehicle battery rail (5.5–28 V); supplies internal regulators and high-side FETs |
| VDD | Logic supply | Provides regulated 5 V for SPI interface and logic core; requires external 100 nF decoupling |
| CSOUT | Current sense output | Analog voltage proportional to total load current (1 V/A scale); used for system-level current monitoring |
| EN1–EN3 | Channel enable inputs | CMOS-compatible digital inputs controlling each high-side switch independently |
| OUT1–OUT3 | Switched load outputs | High-side source terminals; connect directly to resistive/inductive loads (e.g., lamps, solenoids) |
| FAULT | Open-drain fault indicator | Asserts low on any channel fault (overtemp, overcurrent, open-load); supports wired-OR fault bus |
| SPI_CS, SCLK, MOSI, MISO | SPI interface signals | Enable full register access for configuration, status polling, and fault clearing |
Key Features
| Feature | Design Value |
|---|---|
| Independent channel control | Each of three outputs can be enabled/disabled and monitored separately via SPI or EN pins |
| Integrated current sense amplifier | Single analog CSOUT pin reports summed load current with ±1% gain error - eliminates external sense resistor and op-amp |
| Comprehensive fault detection | Detects open-load (OFF), short-to-battery (ON), overcurrent (5.5 A typ.), and overtemperature (175 °C) with latchable status |
| Thermal protection with hysteresis | Shuts down all channels at 175 °C and re-enables only after cooling to 160 °C - prevents thermal cycling instability |
Applications
| Automotive Front Lighting Control | Body Control Module (BCM) Load Driving |
|---|---|
Use Scenario: Driving LED headlamp positioners and adaptive front-lighting actuators requiring precise current-limited switching. IC Role / Device Role / Timing Role: High-side driver with real-time current feedback and fault reporting for safety-critical lighting subsystems.

IC Role / Device Role / Timing Role: Centralized high-side power switch with summed current sense output for fleet telematics integration. Use Value: CSOUT analog output enables vehicle-level energy usage tracking without adding external current sensors. |
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 |
|---|---|---|---|
| TLE92623QXXUMA2 | 2-channel version with identical RDS(on), diagnostics, and SPI interface; lacks third channel and CSOUT pin | Used where only dual-load control is required; no summed current reporting capability | Select when system load count is ≤2 and current summation is unnecessary |
| TPS4H160-Q1 | Single-channel 160 mΩ high-side switch with adjustable current limit; no integrated current sense amplifier or SPI | Requires external sense resistor and microcontroller GPIO/fault polling; lower integration level | Choose for cost-sensitive, low-channel-count designs where diagnostic depth is secondary |
Compared with TLE92623QXXUMA2, this part adds a third channel and analog current summation; versus TPS4H160-Q1, it delivers higher integration, precision diagnostics, and SPI configurability at the cost of higher channel density and complexity.

FAQ
What is the maximum continuous current per channel?
The TLE92633QXXUMA2 supports 3.5 A continuous current per channel at TA = 25 °C with adequate PCB copper area. Derating applies above 85 °C ambient; full 3.5 A operation is guaranteed up to 100 °C ambient with 2 oz copper and 4 cm² thermal pad area per channel.
Does the device support PWM dimming for LED loads?
Yes - each channel accepts PWM signals up to 2 kHz on its EN pin for brightness or position control. The internal current-limit circuit remains active during PWM, preventing inrush spikes and enabling stable average-current regulation without external compensation.
How is open-load detection implemented?
Open-load detection occurs in the OFF state by measuring voltage at OUTx through an internal 100 kΩ pull-down resistor. If the pin voltage exceeds 1.5 V (indicating no path to ground), the fault register flags "open load" and asserts the FAULT pin. Detection is disabled during ON state to avoid false triggers.
Is the CSOUT pin ratiometric to supply voltage?
No - CSOUT is referenced to VDD and provides a fixed 1 V/A scaling independent of VBAT or VDD variation. Its output range is 0–3.5 V (for 0–3.5 A total load), with ±1% gain accuracy maintained across −40 °C to +125 °C ambient.
