Product details
Overview
TLD11141EPXUMA1 from Infineon is a single-channel automotive-grade high-side LED driver IC with integrated protected current source output stage, designed to drive up to 360 mA into LEDs in stop/tail, turn indicator, and DRL applications. It features external resistor–controlled output current (180 mA nominal at 8–18 V), reverse polarity protection, and sleep-mode current of 0.1 µA.
For engineers reviewing the TLD11141EPXUMA1 datasheet, TLD11141EPXUMA1 pinout, TLD11141EPXUMA1 application, or TLD11141EPXUMA1 equivalent, key selection criteria include its AEC-Q100 qualification, dual-output configuration (OUTH/OUTL), Power Shift capability for thermal load offloading, and ERRN-based fault reporting in multi-driver systems.
Technical Context
The TLD11141EPXUMA1 implements a programmable high-side current source with two parallel output paths-OUTH for high-current/low-drop operation (up to 370 mA) and OUTL for precision low-current control (up to 200 mA). Its IN_SET pin accepts either a voltage reference or an external resistor (e.g., 10 kΩ) to set nominal current with ±3.33% accuracy.
It integrates reverse-battery protection, thermal shutdown, and overload detection with open-drain ERRN signaling. The device supports direct cascading via OUT_SET → IN_SET between LITIX™ Basic+ family members and enables power redistribution using PWR_SHG/PWR_SHS pins to drive external NMOS for thermal management.
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 typical start) and load-dump transients. |
| Nominal Output Current | 180 mA at 8–18 V supply - calibrated for stable red LED string driving without thermal derating in standard PCB layouts. |
| Max Output Current | 360 mA - achievable with optimized thermal resistance (RthJA) and Power Shift activation using external NMOS. |
| Sleep Current | 0.1 µA - enables always-on vehicle functions (e.g., position lights) with negligible battery drain over weeks. |
| Fault Current (ERRN active) | ≤850 µA - ensures minimal system-level current draw during fault condition while maintaining diagnostic flag integrity. |
| Current Accuracy | ±3.33% at RSET = 10 kΩ - eliminates need for post-production calibration in cost-sensitive lighting modules. |
| Junction Temp Range | −40°C to +150°C - qualified per AEC-Q100 Grade 0, enabling placement near headlamp heat sources or under-hood locations. |
Pinout & Package
Package: PG-TSDSO-14 (exposed pad), thermally enhanced SOIC variant with GND-connected EP for improved heat dissipation in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS (Pin 9) | Supply input | Connects directly to battery or switched 12 V rail; handles 40 V transients and reverse polarity down to −18 V. |
| GND (Pin 7) | Signal ground | Reference for all analog and digital logic; tied to exposed pad (EP) for thermal and EMI performance. |
| IN_SET (Pin 4) | Current programming input | Accepts resistor divider or voltage reference to set output current; supports daisy-chaining from another LITIX™ driver's OUT_SET. |
| OUT_SET (Pin 2) | Current reference output | Provides matched reference voltage to drive IN_SET of secondary TLD1114-1EP for synchronized multi-channel control. |
| OUTH (Pin 12) | High-current output | Low-VPS path for ≥250 mA loads; used when minimizing forward voltage drop is critical (e.g., high-power tail lamps). |
| OUTL (Pin 13) | Precision low-current output | Higher-resolution path for ≤200 mA; preferred for dimmable ambient lighting or RGB channel control requiring fine-grained current steps. |
| ERRN (Pin 14) | Fault flag I/O | Open-drain error signal shared across multiple drivers; pulls low on thermal overload, short-circuit, or open-load detection. |
| EN (Pin 8) | Enable control | Logic-level or resistor-divider controlled enable; allows centralized power gating of lighting subsystems. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the function of the PWR_SHG and PWR_SHS pins?
PWR_SHG drives the gate of an external NMOS transistor, while PWR_SHS sources current to a power resistor or NMOS source terminal. Together they implement the Power Shift feature, redirecting >50% of power dissipation away from the IC die to maintain safe junction temperature during 360 mA operation on standard PCBs.
Can TLD11141EPXUMA1 drive multiple LED strings simultaneously?
No-it is a single-channel driver. However, its OUT_SET pin provides a buffered current reference that can be connected to the IN_SET pin of additional TLD1114-1EP devices, enabling synchronized current control across up to eight channels without external DACs or microcontroller intervention.
How does the ERRN pin behave during fault conditions?
ERRN is an open-drain output that pulls low during thermal shutdown, output short-to-ground, open-load, or overvoltage events. It remains latched low until the fault clears and EN is toggled, allowing host ECUs to detect and log faults using a single GPIO with pull-up resistor.
Is external compensation required for stability with capacitive LED loads?
No-internal compensation ensures stable operation with up to 100 nF total output capacitance (including PCB trace and LED package parasitics). This eliminates need for external compensation networks, reducing design iterations and qualifying faster for automotive EMC testing.
