TLD700216ESXUMA1 - 16-CH 76.5mA LED Driver | Infineon LITIX
MPN： TLD700216ESXUMA1 ✓ 啟用中TLD700216ESXUMA1 概覽
A linear LED driver is an integrated circuit that regulates current through each LED string directly from the system supply using an internal low-side or high-side pass transistor. Compared with switched-mode LED drivers, linear drivers avoid switching noise and EMI, which simplifies EMC compliance at the cost of higher conduction loss when VIN substantially exceeds the LED forward voltage. The TLD7002-16ES belongs to the broader LED driver category inside the power management IC family, specifically targeting pixel-controlled rear-light applications in automotive lighting.
Key specifications include 16 independent constant-current outputs, 76.5 mA maximum per channel, 14-bit PWM dimming (16,384 steps), an analog dimming input for current setting, an operating supply range of 6 V to 20 V, and a load-dump tolerance up to 40 V. Integrated diagnostics include open-load, short-to-ground, and short-to-supply detection on every channel, plus an integrated thermal sensor and overtemperature shutdown. Communication is via SPI with a daisy-chain option for multi-device addressing across large pixel arrays.
Architecturally, the device uses an internal bandgap reference and per-channel current mirrors with low-side regulation, paired with a state machine for sequenced diagnostics and PWM generation. The 14-bit PWM timer is generated on-chip from an internal oscillator, eliminating the need for an external clock for dimming. Functional-safety features include ISO 26262 ASIL-B capability, allowing deployment in rear lamps where ASIL classification is required.
Typical applications include automotive dynamic rear lamps, sequential turn indicators, animated tail-light signatures, and pixel-controlled interior ambient lighting. Its small PG-TSDSO-24-5 footprint and SPI control suit it to distributed pixel-driver nodes connected to a central body or lighting ECU.
When designing with the TLD7002-16ES, ensure the supply is reverse-polarity protected and that the EP thermal pad receives a continuous copper pour sized to keep junction temperature within the -40 C to +125 C operating range. Use the SPI daisy-chain mode to expand channels without increasing microcontroller GPIO count.

典型應用
TLD700216ESXUMA1 適用於 6 應用s: Automotive Dynamic Rear Lamps, Sequential Turn Indicators, Animated Tail-Light Signatures, Pixel-Controlled Interior Ambient Lighting, Status and Decorative LED Matrix Displays, Automotive Diagnostic Warning Lamps.
Automotive Dynamic Rear Lamps
The TLD700216ESXUMA1's 16 individually controlled 76.5 mA channels and 14-bit PWM resolution make it ideal for animated rear-light signatures such as dynamic turn indicators and welcome/farewell sequences. Each channel's 14-bit dimming yields 16384 brightness steps, eliminating visible stepping during fade transitions. The SPI daisy-chain interface allows multiple ICs to be linked on one microcontroller bus, scaling pixel counts beyond 16 without increasing GPIO demand. Integrated open-load and short-circuit diagnostics on every channel help the body ECU meet ISO 26262 ASIL-B rear-lamp requirements, and the 40 V load-dump tolerance handles 12 V automotive transients directly without external TVS components.
推薦
Sequential Turn Indicators
Sequential turn indicators require per-LED precise timing and brightness control, which the TLD700216ESXUMA1 delivers via its on-chip 14-bit PWM generator. Channel-to-channel skew is locked to the SPI clock domain, so sweeping animations remain visually smooth even at refresh rates above 200 Hz. The 76.5 mA per channel is well-matched to typical 12 V automotive LED forward voltages of 2.0-3.5 V per die, supporting 3-LED strings. The exposed-pad PG-TSDSO-24-5 package keeps the PCB footprint small enough to mount the driver behind the lamp housing itself, simplifying wiring harness design and reducing EMI loop area.
推薦
Animated Tail-Light Signatures
For premium tail-light signatures with animated boot-up and shut-down sequences, the TLD700216ESXUMA1 provides the per-pixel resolution and dimming depth required. Its 14-bit PWM dimming, paired with per-channel analog current setting via ISET, enables both fine-grained color and brightness mixing. The PG-TSDSO-24-5 package allows the IC to be embedded directly inside the lamp module, close to the LED PCB, minimizing the high-current LED trace length and improving EMI. ISO 26262 ASIL-B capability supports functional-safety documentation required by OEMs for rear combination lamps.
推薦
Pixel-Controlled Interior Ambient Lighting
Interior ambient RGB lighting benefits from the TLD700216ESXUMA1's fine 14-bit PWM dimming, which produces smooth color-mixing transitions without visible flicker. With 16 channels, one driver can control a full RGB strip plus spare channels for footwell or door-panel lighting. The -40 C to +125 C operating range covers all cabin thermal conditions, including direct sunlight through windows. SPI daisy-chaining enables multiple lighting zones across the cabin to share a single microcontroller SPI port, reducing wiring complexity in the body harness.
推薦
Status and Decorative LED Matrix Displays
Beyond automotive lighting, the TLD700216ESXUMA1 suits any 16-pixel addressable LED matrix where SPI control and per-pixel PWM are needed. Its 76.5 mA per channel is sufficient for high-brightness single-die LEDs and for moderate-brightness multi-die packages. The 14-bit PWM resolution makes it useful for status-indicator panels where subtle breathing animations communicate device state without distracting the user. SPI daisy-chaining scales easily to larger matrices by stacking ICs along the same bus without additional microcontroller pins.
推薦
Automotive Diagnostic Warning Lamps
Warning lamps that must indicate fault conditions with high reliability benefit from the TLD700216ESXUMA1's per-channel open-load, short-to-ground, and short-to-supply diagnostics. These built-in checks enable the lamp ECU to detect LED failures in real time and report them over CAN or LIN to the instrument cluster. Combined with the device's ASIL-B capability, this supports functional-safety requirements for mandatory warning lamps such as brake, turn, and hazard indicators. The exposed-pad package and 40 V load-dump tolerance allow direct connection to the 12 V automotive battery rail.

主要差異化特點
- On-chip 14-bit PWM generator eliminates external timing MCU (對比TLD2331-3EP)
- Per-channel open-load, short-to-GND, and short-to-VS diagnostics (對比ITS4090QEPDXUMA1)
- SPI daisy-chain for scalable pixel arrays without extra GPIO (對比TLE94112ESXUMA1)
設計說明
The TLD700216ESXUMA1 dissipates up to 0.0765 A x (VS - VLED) per channel. At VS=12 V with 4 LEDs in series (VLED=12 V), dissipation is minimal, but at lower LED stack voltages dissipation rises quickly. Estimated: at VS=12 V, VLED=6 V, IOUT=76.5 mA on 16 channels, total dissipation is approximately 7.3 W. The PG-TSDSO-24-5 package requires a continuous copper pour of at least 1 square inch on the top and bottom layers tied with thermal vias directly under the exposed pad to keep junction temperature below 125 C in a 85 C ambient.
Place the ISET resistor within 5 mm of pin 18 to avoid noise pickup. Add a 100 nF decoupling capacitor within 3 mm of the VS pin (pin 1), plus a 10 uF bulk capacitor on the VS rail. Route the SPI traces (SDI, SDO, SCLK, CSN) as a 4-wire bus with ground guard traces; keep trace lengths matched if multiple ICs share the bus in daisy-chain mode. The exposed pad must be soldered to a copper pour covering at least 80% of the pad area.
Do not leave any OUT pin floating if unused - tie unused OUT pins to GND through a 10 kohm resistor so the open-load diagnostic does not trigger false faults. Ensure CSN is held low during SPI transactions and pulled high during power-up to avoid spurious configuration writes. The SPI clock frequency must not exceed the maximum specified in the datasheet, or register reads will return corrupted data. Finally, verify the LED stack forward voltage at the worst-case cold temperature (-40 C) to ensure VS - VLED_stack remains within the linear regulator dropout envelope.
