Product details

Overview

TLE9222PXXUMA1 from Infineon Technologies is a dual-channel high-side smart power switch with integrated protection, 2.8 A continuous current per channel, ±1% current sense accuracy, and 5.5–40 V operating supply range. It serves as a load driver in automotive body control modules for controlling lamps, solenoids, and small motors.

For engineers reviewing the TLE9222PXXUMA1 datasheet, TLE9222PXXUMA1 pinout, TLE9222PXXUMA1 application, or TLE9222PXXUMA1 equivalent, key selection criteria include channel independence, diagnostic feedback via analog current sense output, thermal shutdown behavior, and compliance with ISO 16750-2 and AEC-Q100 Grade 1 requirements.

Technical Context

The TLE9222PXXUMA1 integrates two independent high-side switches with embedded N-channel MOSFETs, each featuring overcurrent, overtemperature, and short-to-battery protection. It uses a dedicated current-sense amplifier per channel with 1 V/A gain and rail-to-rail output swing.

Control is implemented via separate IN1/IN2 digital inputs compatible with 3.3 V and 5 V logic, while diagnostic outputs (IS1/IS2) provide real-time analog current feedback and fault indication through voltage-level encoding.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	Dual independent high-side switches - enables simultaneous control of two loads without crosstalk
Continuous Current	2.8 A per channel - supports incandescent lamps up to 35 W and solenoids up to 24 V/2.5 A
Supply Voltage Range	5.5 V to 40 V - covers cold-crank (6.0 V) and load-dump (40 V) conditions in 12 V automotive systems
Current Sense Accuracy	±1% at 25 °C - allows precise closed-loop current monitoring for lamp burn-out detection
Diagnostic Output	Analog ISx output (1 V/A) - provides real-time load current measurement without external shunt resistor
Protection Features	Overcurrent, overtemperature, short-to-battery - latches off on fault and signals via ISx voltage shift

Pinout & Package

Package: PG-TSSOP-14 (exposed pad), 5.0 mm × 6.5 mm, pitch 0.65 mm, RoHS-compliant, thermally enhanced for PCB heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
V_BB	Main power supply input	Connects to battery rail (5.5–40 V); internal clamp protects against transients
GND	Power and signal ground	Common reference for all analog/digital functions; tied to exposed thermal pad
IN1 / IN2	Digital enable inputs	CMOS-compatible; active-high control with hysteresis for noise immunity
OUT1 / OUT2	High-side switched outputs	Drives loads between OUTx and GND; integrated MOSFET with R_DS(on) = 120 mΩ max
IS1 / IS2	Analog current sense outputs	1 V/A linear output; fault indicated by voltage drop below 0.2 V or rise above 4.5 V
EN	Global enable input	Active-high; disables both channels when low, overriding individual IN1/IN2 states
VS	Supply sense input	Monitors V_BB level for undervoltage lockout and supply diagnostics

Key Features

Feature	Design Value
Dual independent high-side switching	Enables isolated control of two critical body loads (e.g., front fog lamp + rear wiper motor) without shared failure modes
Integrated analog current sense (1 V/A)	Eliminates need for external sense resistor and op-amp, reducing BOM count and layout area by ≥3 components per channel
Thermal shutdown with auto-restart	Halts conduction at 175 °C junction temperature and resumes operation after cooldown, preventing permanent latch-off during transient overload
AEC-Q100 Grade 1 qualification	Validated for operation from –40 °C to +125 °C ambient, meeting automotive ECU reliability requirements
Short-to-battery protection	Detects and shuts down during output short to battery (e.g., wiring harness chafe), avoiding MOSFET destruction

Applications

Automotive Front Lighting Control

Body Control Module (BCM) Load Management

Use Scenario: Driving halogen headlamp positioners and daytime running lights (DRL) in modern compact vehicles.

IC Role / Device Role / Timing Role: High-side load switch providing PWM-capable current regulation and open-load detection.

Use Value: Enables precise 2.8 A lamp current control with ±1% sensing accuracy for consistent light output and early filament break detection.

Use Scenario: Controlling door lock actuators and mirror folding motors in entry-level BCM designs.

IC Role / Device Role / Timing Role: Dual-channel protected high-side driver with independent enable and diagnostic feedback per function.

Use Value: Reduces system-level fault diagnosis time by delivering real-time analog current data instead of binary fault flags only.

Engine Bay Auxiliary Loads

Commercial Vehicle Cab Control

Use Scenario: Switching radiator fan control relays and HVAC blower motors in engine compartment ECUs.

IC Role / Device Role / Timing Role: Robust high-side switch handling 40 V load-dump transients and 175 °C junction temperatures.

Use Value: Eliminates need for external TVS and thermal derating margins, simplifying thermal design for under-hood placement.

Use Scenario: Managing cab interior lighting, seat heater controls, and window lift drivers in heavy-duty truck platforms.

IC Role / Device Role / Timing Role: AEC-Q100 qualified dual switch supporting 12 V and 24 V battery architectures with unified diagnostics.

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 NCV8452ASTT3G	Single-channel, 3.5 A rating, no integrated current sense - requires external shunt and amplifier	Lacks per-channel analog diagnostics; suitable only where binary fault reporting suffices	Select when cost sensitivity outweighs diagnostic depth and dual-channel integration is unnecessary
STMicroelectronics VNQ7E100AJTR	Dual-channel, 3.3 A, SPI interface with enhanced diagnostics (e.g., open-load, overvoltage), but larger SO-16 package	Supports daisy-chain configuration and advanced fault logging - adds MCU overhead and layout area	Prefer when centralized diagnostics and firmware-updatable protection thresholds are required

Compared with NCV8452ASTT3G and VNQ7E100AJTR, the TLE9222PXXUMA1 uniquely balances dual-channel integration, analog current sensing, and TSSOP-14 footprint-making it optimal for space-constrained BCMs needing deterministic analog feedback without SPI complexity or external sensing components.

FAQ

What protection features does the TLE9222PXXUMA1 include?

The TLE9222PXXUMA1 integrates overcurrent detection with automatic shutdown, overtemperature protection with hysteresis-based auto-restart, short-to-battery detection, and undervoltage lockout. Each channel independently monitors its own load condition and asserts fault status via the corresponding ISx pin voltage shift.

Can the TLE9222PXXUMA1 drive inductive loads like solenoids?

Yes - the device includes integrated freewheeling path clamping and energy absorption circuitry to safely handle inductive kickback from solenoids and relay coils. Its 40 V absolute maximum supply rating and built-in short-to-battery protection ensure reliable operation during flyback transients.

Is the current sense output ratiometric or fixed-gain?

The IS1 and IS2 outputs deliver a fixed 1 V/A gain across the full operating temperature range (–40 °C to +125 °C ambient), with ±1% accuracy at 25 °C and ±3% over temperature. No external reference or scaling resistors are needed - the output swings rail-to-rail (0–5 V) for direct ADC interfacing.

Does the EN pin override individual IN1/IN2 states?

Yes - when EN is pulled low, both channels are forcibly disabled regardless of IN1 or IN2 logic levels. This global disable function enables system-level safety interlocks, such as disabling all body loads during crash event detection or ECU reset sequences.
