Product details

Overview

TLD1310ELXUMA1 from Infineon Technologies is a 3-channel high-side LED current source IC for automotive exterior and interior lighting. It delivers up to 120 mA per channel with ±7% current accuracy (at R_SET = 12 kΩ), operates from 5.5 V to 40 V supply, and integrates thermal, overload, reverse polarity, and undervoltage protection. Used in tail/brake lights and dashboard ambient lighting.

For engineers reviewing the TLD1310ELXUMA1 datasheet, TLD1310ELXUMA1 pinout, TLD1310ELXUMA1 application, or TLD1310ELXUMA1 equivalent, key selection factors include its PG-SSOP-14 exposed-pad package, EN-controlled sleep mode (0.1 µA), VS-referenced PWM capability, and adjustable output current via external resistor - all critical for thermally constrained automotive LED driver designs.

Technical Context

The TLD1310ELXUMA1 implements three independent high-side current sources with integrated power stages, each regulated by an external R_SET resistor and internally compensated for load and supply voltage variation. Its EN pin enables dual-mode control: logic-level enable/disable and VS-referenced PWM dimming.

Thermal management relies on junction-to-case (R_thJC = 8–10 K/W) and junction-to-ambient (R_thJA = 43–61 K/W depending on PCB stack-up) metrics validated per JEDEC JESD51-3/5/7. Protection functions operate outside normal operating range and are not intended for repetitive fault cycling.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	3 independent high-side current sources, enabling simultaneous control of three LED strings without external MOSFETs
Max Output Current	120 mA per channel - supports high-brightness red/amber LEDs in brake/tail light clusters
Current Accuracy	±7% at R_SET = 12 kΩ - ensures consistent luminance across channels without calibration
Sleep Current	0.1 µA - meets automotive off-state leakage requirements for battery-sensitive systems
Supply Range	5.5 V to 40 V - covers cold-crank (5.5 V) to load-dump (40 V) transients in 12 V automotive systems
Junction Temp	-40°C to +150°C - qualified for under-hood and lamp housing environments
Package	PG-SSOP-14 with exposed thermal pad - enables direct PCB copper pour attachment for <45 K/W R_thJA on 2s2p boards

Pinout & Package

PG-SSOP-14 package with exposed thermal pad (EP), designed for surface-mount assembly and direct thermal coupling to PCB ground plane. Pin 1–14 follow standard SSOP numbering; EP must be soldered to GND for thermal and electrical integrity.

Pin/Terminal	Circuit Role	Design Meaning
VS (Pins 1,2)	Power supply input	Dual VS pins reduce IR drop and improve decoupling stability; requires 100 nF–1 µF ceramic capacitor to GND
EN (Pin 3)	Enable / PWM control input	Logic-compatible input supporting both ON/OFF enable and VS-referenced PWM dimming; I_EN adds to total supply current
OUT1–OUT3 (Pins 11–13)	High-side current outputs	Each drives LED anodes directly; no external flyback diode needed due to integrated clamp and protection
IN_SET (Pin 6)	Current-setting reference input	Accepts external resistor (e.g., 10 kΩ) to set nominal current; supports PTC integration for overtemperature LED derating
GND / GNDS / EP (Pins 5,9,14 + EP)	Ground return paths	GNDS is signal ground; all GND pins and EP must be tied together at single-point low-impedance node for noise immunity

Key Features

Feature	Design Value
Integrated high-side current regulation	Eliminates need for external sense resistors and MOSFETs - reduces BOM count and layout area in multi-LED modules
VS-referenced PWM dimming	Enables direct microcontroller GPIO control without level-shifting circuitry - simplifies interface with 3.3 V/5 V MCUs
Thermal derating via PTC on IN_SET	Allows dynamic current reduction during LED overheating - preserves luminance consistency while preventing thermal runaway
Reverse polarity & load dump protection	Withstands -16 V reverse battery connection and 40 V transients - meets ISO 7637-2 Pulse 5a requirements without external TVS
Low sleep-mode current	0.1 µA draw maintains battery life in always-on vehicle architectures (e.g., position lights active during parking)

Applications

Rear Combination Lamp

Dashboard Ambient Lighting

IC Role / Device Role / Timing Role: Fault-tolerant high-side driver with integrated reverse polarity and overload protection.

Use Value: Withstands -16 V reverse battery and 40 V load dump pulses - eliminates need for external protection components in cost-sensitive modules.

Use Scenario: Door-mounted LED strips activated on entry/exit with gradual fade-in/out behavior.

IC Role / Device Role / Timing Role: Enable-controlled current source supporting microsecond-resolution PWM via EN pin.

Use Value: 0.1 µA sleep current prevents parasitic drain during vehicle standby - extends battery life beyond 30 days in parked state.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side LED driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NCV7683	3-channel, 60 mA max per channel; requires external sense resistor; no integrated thermal derating path	Lacks PTC-based current foldback; less suited for thermally constrained lamp housings	Prefer when lower channel current and discrete sensing are acceptable for cost optimization
NXP PCA9956BT	I²C-controlled 16-channel LED driver; 25 mA max per channel; requires external FETs for high-side drive	Software-configurable but lacks integrated high-side power stage and automotive transient protection	Choose for programmable multi-zone lighting where MCU coordination outweighs analog simplicity

Compared with NCV7683 and PCA9956BT, the TLD1310ELXUMA1 provides higher per-channel current (120 mA), integrated protection (reverse polarity, load dump), and hardware-based thermal derating - making it optimal for compact, robust, and thermally demanding automotive LED modules without software overhead.

FAQ

What is the recommended R_SET value for 60 mA nominal output current?

The datasheet specifies that a 12 kΩ resistor on IN_SET yields 60 mA nominal output current per channel under 8–18 V supply conditions. This value achieves ±7% accuracy and supports PTC integration for thermal derating. Use 1% metal-film resistors for best matching across channels.

Can the EN pin be used for PWM dimming without additional level-shifting circuitry?

Yes - the EN pin accepts VS-referenced PWM signals directly. When VS = 12 V, a 0–12 V square wave applied to EN modulates output current proportionally. No level shifter is needed, enabling direct connection to automotive microcontrollers with 5 V or 12 V GPIO outputs.

How does the exposed thermal pad (EP) affect thermal performance?

The exposed pad must be soldered to a minimum 300 mm² copper pour connected to GND. On a 2s2p FR4 board, this achieves R_thJA ≈ 43 K/W at 135°C ambient, allowing full 120 mA per channel at ≤105°C junction temperature. Omitting EP connection degrades R_thJA by >25 K/W.

Does the device support daisy-chained communication or I²C configuration?

No - the TLD1310ELXUMA1 is an analog-controlled, pin-strapped LED driver with no serial interface. Configuration is done exclusively via external resistors (R_SET) and logic inputs (EN). For I²C-configurable alternatives, consider Infineon's LITIX™Smart family.
