Product details
Overview
TLD21313EPXUMA1 from Infineon Technologies is a triple-channel automotive-grade high-side LED driver IC with integrated protected current sources, designed for precise 60 mA (nominal) per channel LED control in 8–18 V systems. It features 0.1 µA sleep-mode current, ±5% current accuracy at RSET = 10 kΩ, and reverse polarity protection - enabling cost-effective tail/stop light implementations with shared or separated LEDs.
For engineers reviewing the TLD21313EPXUMA1 datasheet, TLD21313EPXUMA1 pinout, TLD21313EPXUMA1 application, or TLD21313EPXUMA1 equivalent, key selection criteria include its PG-TSDSO-14 package, ERRN-based fault network scalability (up to 16 devices), SLS_REF/DS-based single-LED short detection, and direct LITIX™ Companion compatibility for expanded channel count without external components.
Technical Context
The TLD21313EPXUMA1 implements three independent high-side current-regulated output stages controlled via IN_SET (current reference input) and OUT_SET (current reference output), enabling daisy-chained multi-device configurations. Each channel supports up to 80 mA load current with thermal shutdown and reverse-battery protection built-in.
Its diagnostic architecture uses open-drain ERRN for shared error signaling, D-pin configurable delay/restart behavior, and dedicated SLS_REF/DS pins for adaptive single-LED short detection with capacitor-timed retry strategies - all operating across -40°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 5.5 V to 40 V - supports full automotive battery range including cold-crank (4.5 V not guaranteed, but functional down to 5.5 V nominal) |
| Output Current (per channel) | 60 mA nominal / 80 mA max - set by external RSET, stable over supply and load variations |
| Current Accuracy | ±5% at RSET = 10 kΩ - enables predictable LED brightness without calibration |
| Sleep Mode Current | 0.1 µA typical - minimizes parasitic drain in always-on vehicle modules |
| Fault Reporting Current | ≤850 µA on ERRN during inter-device fault - ensures low-power error network operation |
| Junction Temp Range | -40°C to +150°C - qualified per AEC-Q100 Grade 0, suitable for under-hood and lamp housing placement |
| Package | PG-TSDSO-14 (exposed pad) - provides enhanced thermal dissipation for sustained 60 mA/channel operation |
Pinout & Package
Package: PG-TSDSO-14 with exposed thermal pad (EP) connected to GND in PCB layout for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SLS_REF) | Single LED Short reference input | Adjusts internal SLS threshold voltage via external resistor; connect to GND if unused |
| 2 (OUT_SET) | Current reference output | Drives IN_SET of companion device for synchronized current setting; leave open if unused |
| 4 (IN_SET) | Current reference input | Sets all three output currents via external RSET; accepts voltage or current reference from another driver |
| 5 (DS) | Single LED short delay/restart control | Configures retry timing for SLS faults using external capacitor; open or GND for fixed behavior |
| 6 (PWMI) | PWM dimming input | Accepts external PWM signal for digital dimming; tie to GND if analog-only control used |
| 7 (D) | Disable/delay error input | Controls fault response timing and retry strategy via capacitor or GND connection |
| 9 (EN/DEN) | Enable/diagnosis control input | Activates outputs and diagnostics when pulled above threshold; supports Zener/resistor divider biasing |
| 10 (VS) | Main supply input | Connects to battery or switched 12 V rail; includes internal ESD and reverse-polarity protection |
| 11–13 (OUT3–OUT1) | High-side output channels | Each drives LED anode directly; supports up to 40 V load voltage swing relative to GND |
| 14 (ERRN) | Open-drain error flag I/O | Active-low shared fault bus; requires external pull-up; supports wired-OR network of ≤16 devices |
| 8, EP (GND) | Signal and thermal ground | Pin 8 is signal GND; exposed pad (EP) must be soldered to PCB GND plane for thermal and EMI integrity |
Key Features
| Feature | Design Value |
|---|---|
| Triple high-side current sources | Three independent 60 mA (nominal) regulated outputs eliminate need for external current-setting resistors per channel |
| Shared ERRN fault network | Enables up to 16 devices on one error line with single external pull-up resistor - reduces wiring and MCU GPIO count |
| Reverse polarity protection | Operates down to 5.5 V supply and withstands -18 V reverse battery - removes need for external reverse-protection diode |
| Single LED short (SLS) diagnosis | Detects short-circuit in individual LED within multi-LED string using SLS_REF/DS pins - prevents false OL/SC flags |
| LITIX™ Companion direct drive | OUT_SET → IN_SET daisy-chain allows expansion to >3 channels without additional controllers or level-shifting circuitry |
Applications
| Automotive Tail/Stop Lights | Animated Turn Indicators |
|---|---|
|

Use Scenario: Sequential turn indicator with dynamic "wiping" effect across multiple LED positions using timed channel enable/disable. IC Role / Device Role / Timing Role: Three-channel driver executing phase-shifted PWM via PWMI and IN_SET modulation, coordinated through MCU-controlled EN/DEN sequencing. Use Value: Enables smooth animation without external MOSFETs or timing ICs - all timing and current regulation handled internally with <1% channel-to-channel mismatch. |
| Daytime Running Light (DRL) | RGB Ambient Interior Lighting |
|
Use Scenario: Constant-current DRL module powered directly from vehicle battery, requiring stable output despite wide input voltage swings (9–16 V). IC Role / Device Role / Timing Role: High-side current source maintaining 60 mA per channel across full VS range, with thermal foldback activated only above 150°C junction temperature. Use Value: Delivers consistent luminance without feedback loop or microcontroller intervention - meets ECE R87 photometric stability requirements. |
Use Scenario: RGB dashboard lighting system where each color channel (R/G/B) is driven by one TLD21313EPXUMA1 output for independent current tuning. IC Role / Device Role / Timing Role: Per-color current regulator accepting separate IN_SET references for white-point calibration and PWMI inputs for synchronized dimming. Use Value: Achieves <±2% chromaticity deviation across temperature via matched current accuracy - eliminates need for per-channel ADC calibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-channel high-side LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ASL3416SHY | Quad-channel, 120 mA max per channel, SPI interface, no SLS detection | Requires MCU for configuration and fault interpretation; lacks integrated single-LED short diagnosis | Select when higher per-channel current and digital control outweigh need for analog simplicity and autonomous SLS handling |
| TLD20313EPXUMA1 | Same pinout and feature set, but rated for 45 mA nominal (vs. 60 mA); identical package and diagnostics | Lower thermal derating required; suitable for lower-brightness interior functions where 60 mA is excessive | Select when thermal budget is constrained or target LED forward voltage is <2.2 V, reducing power dissipation needs |
Compared with ASL3416SHY and TLD20313EPXUMA1, the TLD21313EPXUMA1 uniquely balances 60 mA nominal drive capability, autonomous SLS diagnosis, and analog-only configurability - making it optimal for cost-sensitive, MCU-light automotive lighting nodes requiring robust open/short detection without communication overhead.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TLD21313EPXUMA1 is rated for continuous operation up to +150°C junction temperature, validated per AEC-Q100 Grade 0. Thermal shutdown activates above this threshold, and the device resumes normal operation once TJ falls below 140°C hysteresis. PCB layout with full EP grounding is required to sustain 60 mA/channel at ambient >105°C.
Can the ERRN pin be used without an external pull-up resistor?
No - ERRN is an open-drain output requiring an external pull-up resistor to VS or a logic rail. Typical value is 10 kΩ; values <4.7 kΩ increase fault-reporting speed but raise quiescent current. Without pull-up, ERRN cannot assert active-low fault signals to other devices or the MCU.
How does the device handle single LED short (SLS) detection in a multi-LED string?
SLS detection compares voltage drop across a reference resistor (SLS_REF) against internal thresholds. When one LED shorts, current redistribution raises voltage at DS, triggering a timed fault response. The DS capacitor sets retry interval; open DS enables immediate retry, while GND forces latched-off behavior until reset via EN/DEN.
Is OUT_SET compatible with non-Infineon LED drivers?
OUT_SET provides a buffered 1.25 V reference current source optimized for driving IN_SET of other LITIX™ Basic+ devices. While it may interface with third-party drivers having compatible input impedance (<10 kΩ) and voltage range (0–6 V), functionality and accuracy are not guaranteed outside Infineon's validated companion ecosystem.
