TLD23313EPXUMA1 Overview
A high-side LED driver is a constant-current source placed between the supply rail and the LED load; it regulates the LED current by modulating the high-side switch rather than the low-side return. Compared to low-side drivers, high-side topologies eliminate the need for the LED cathode to be tied to chassis ground, which simplifies PCB layout, removes ground-shift issues, and provides protection against single-LED short-to-ground faults. The LITIX Basic+ TLD2331-3EP is purpose-built for cost-sensitive automotive exterior and interior lighting applications where PCB area and BOM cost are tightly constrained.
Key features include three integrated output stages rated up to 80 mA per channel, digital PWM dimming capability, built-in over-temperature protection with thermal shutdown, and short-circuit / open-load detection. The PG-TSDSO-14 package offers an exposed thermal pad that keeps junction temperature manageable even when driving three parallel LED strings at full current, while the wide 5.5 V to 40 V input range tolerates load-dump transients common in 12 V automotive environments. Programmable output current is set by an external sense resistor on the IS pin.
Typical applications include automotive rear combination lamps, daytime running lights (DRL), interior ambient lighting, instrument-cluster backlighting, and motorcycle / e-bike tail-light clusters. The triple-channel integration lets a single IC drive stop / tail / turn or position / DRL / indicator functions that previously required two or three discrete channels.
Designers should note that adequate thermal copper under the exposed pad is essential: with three channels at 60 mA each from a 13 V supply, internal dissipation can approach 1 W and demands at least 1 square centimeter of copper pour for reliable operation. The PWM frequency should be selected above 100 Hz to avoid visible flicker in human-perception applications.

Typical Applications
TLD23313EPXUMA1 is suitable for 6 applications: Automotive Rear Combination Lamps, Daytime Running Lights (DRL), Interior Ambient Lighting, Instrument Cluster Backlighting, Motorcycle and E-Bike Tail Lights, Industrial Status Indicator LEDs.
Automotive Rear Combination Lamps
The TLD23313EPXUMA1 is purpose-built for automotive rear-lighting modules where three independently dimmable channels drive stop, tail, and turn-indicator LEDs from a single 14-pin IC. Its 5.5 V to 40 V input range covers 12 V body-net cold-crank and load-dump events per ISO 7637, eliminating the need for a pre-regulator on the lamp board. The 60 mA per-channel rating drives high-brightness LEDs used in modern rear lamp clusters, and the PG-TSDSO-14 exposed pad keeps the junction temperature within the -40 C to +150 C automotive envelope even with all three channels active. PWM dimming through a single input pin lets the body controller modulate tail/DRL brightness without external MOSFETs, replacing three discrete low-side channels that would otherwise consume more PCB area and BOM cost.
Recommended
Daytime Running Lights (DRL)
The TLD23313EPXUMA1 drives daytime running light LED strings from the 12 V board-net, with its high-side topology eliminating ground-shift concerns across long wiring harnesses from the BCM to the front lamp. Three integrated channels support position, DRL, and indicator functions from a single IC footprint, shrinking the front-lighting PCB by roughly 40 percent versus discrete low-side designs. Per the LITIX Basic+ datasheet, the wide 5.5 V to 40 V input tolerates cranking transients down to 6 V while maintaining constant LED current, which is critical for daytime safety lighting that must remain visible during engine start. Programmable output current via the IS pin lets one IC serve multiple DRL power levels without hardware changes.
Recommended
Interior Ambient Lighting
The TLD23313EPXUMA1 supports RGB ambient-lighting strips in vehicle cabins, where three independently PWM-dimmed channels map directly to red, green, and blue LED strings driven from the same IC. Its low quiescent current keeps standby drain below 1 mA on always-on ambient circuits that stay connected to battery during parking, while the small PG-TSDSO-14 outline fits behind door-panel trim and headliner modules. Per the Infineon LITIX portfolio, the PWM input responds in microseconds, enabling smooth color cross-fades driven by the body-controller LIN or CAN network. The exposed thermal pad keeps the junction cool under continuous RGB operation at 60 mA per channel, supporting long cabin-illumination duty cycles.
Recommended
Instrument Cluster Backlighting
The TLD23313EPXUMA1 provides uniform backlighting for instrument-cluster gauges and infotainment displays, where three channels can drive upper, lower, and accent zones from a single IC behind the cluster PCB. Its constant-current regulation matches LED brightness across production tolerances and temperature extremes, eliminating visible brightness variation in safety-critical gauges. Per the LITIX Basic+ datasheet, the part's PWM dimming allows day/night brightness transitions to be controlled by the cluster microcontroller without additional driver stages. The wide operating temperature range from -40 C to +150 C covers under-dash thermal stress in cold-start and direct-sunlight conditions typical of vehicle cockpits.
Recommended
Motorcycle and E-Bike Tail Lights
The TLD23313EPXUMA1 is well-suited to two-wheeler tail-light assemblies combining brake, tail, and turn-indicator functions in a compact housing where PCB area is at a premium. Its 14-pin PG-TSDSO package and integrated three-channel design replace three discrete transistor channels that would otherwise not fit on a small tail-light board, while the 5.5 V to 40 V input covers both 6 V and 12 V motorcycle electrical systems. Per the Infineon LITIX portfolio, thermal shutdown and short-circuit protection are essential for vibration-heavy two-wheeler environments where wiring faults can ground LED strings. PWM dimming through a single input simplifies the brake/tail intensity switching required for combined-function lamps.
Recommended
Industrial Status Indicator LEDs
The TLD23313EPXUMA1 drives multi-color status indicators on industrial control panels and PLCs, where three channels can independently control red/yellow/green machine-state lamps from a single 24 V supply. Its 40 V maximum input rating tolerates 24 V industrial-rail transients and reverse-battery events common in factory automation, while its exposed thermal pad handles continuous-on duty cycles in always-running production lines. Per the Infineon datasheet, the device's open-load detection reports broken-LED faults back to the PLC, supporting predictive-maintenance diagnostics in process-control applications. The PG-TSDSO-14 package enables compact DIN-rail indicator modules where multiple status lamps must coexist on a small front-panel footprint.

Key Differentiators
- Three independent 60 mA channels in a 14-pin package (vs TLE4242G)
- Higher channel count than single-channel LITIX devices (vs TLD1125ELXUMA1 / TLD1211SJFUMA1)
- Integrated high-side linear driver versus controller-plus-MOSFET (vs TLD5097EPXUMA1)
Design Notes
Estimated: with three channels at 60 mA each from a 13 V supply into LED forward voltage of 2.0 V, internal dissipation is roughly 3 * (13 V - 2.0 V) * 0.060 A = 1.98 W. The PG-TSDSO-14 package requires at least 1 square centimeter of top-layer copper (preferably 2-4 cm^2 with thermal vias to inner planes) to keep the junction below the 150 C automotive rating. For higher-current or higher-input-voltage applications, derate the per-channel current or add external heat-sinking. Verify with the Infineon thermal-derating curves in the manufacturer datasheet.
Place the ISET resistor as close as possible to the IS pin and GND to minimize noise injection into the current-sense loop. Keep the high-current OUT traces wide (>= 0.5 mm per 60 mA) and pair them with a ground-return path to avoid supply-voltage dips during PWM transitions. Per Infineon LITIX Basic+ layout guidance, place the input decoupling capacitor within 5 mm of the IN pin and connect the exposed thermal pad to a continuous copper pour with at least four thermal vias for proper heat extraction.
Do not exceed the 40 V absolute-maximum supply rating - load-dump transients on 12 V automotive rails can briefly reach 35 V to 40 V, so an external TVS diode is recommended for ISO 7637-2 compliance. Avoid PWM frequencies below 100 Hz in human-perception applications (ambient lighting, instrument clusters) to prevent visible flicker. Per the Infineon datasheet, leaving the SET pin floating forces the device into a defined default state - always tie SET to a defined logic level through a resistor or microcontroller GPIO to avoid startup glitches.
Route the PWM dimming trace away from switching power stages and away from the high-current OUT traces to avoid capacitive coupling that can distort the dimming waveform. Per the LITIX Basic+ reference designs, a 10 kHz to 1 kHz PWM range is supported; route the diagnostic output through a pull-up resistor to the logic-level rail if the body controller monitors fault conditions. Keep the ISET resistor ground node star-connected to the IC ground pin to prevent ground-bounce from corrupting the constant-current regulation.
