Product details
Overview
CY8CLED02D01-56LTXI from Infineon Technologies (formerly Cypress Semiconductor) is a PowerPSoC® intelligent LED driver IC integrating an M8C 8-bit CPU core, programmable analog/digital peripherals, and high-voltage gate drivers for LED current regulation. It supports up to 4 independent LED channels with 12-bit PWM dimming resolution, operates from 5.5 V to 28 V input, and features integrated current sense amplifiers and hysteretic controllers for constant-current LED driving in architectural lighting systems.
For engineers reviewing the CY8CLED02D01-56LTXI datasheet, CY8CLED02D01-56LTXI pinout, CY8CLED02D01-56LTXI application, or CY8CLED02D01-56LTXI equivalent, key selection considerations include its integrated gate driver voltage rating (up to 40 V), on-chip current sense amplifier gain (10 V/V), 12-bit digital PWM resolution, and 56-pin QFN package with thermal pad - all critical for compact, thermally constrained LED driver designs.
Technical Context
This device combines a configurable mixed-signal array with a dedicated PSoC core to implement closed-loop LED current control without external op-amps or PWM generators. Its hysteretic controller operates at up to 2 MHz switching frequency, and the integrated 10-bit SAR ADC enables real-time current monitoring with ±1% full-scale accuracy.
The PowerPSoC architecture uses a global digital interconnect (GDI) and row-level digital interconnect (RDI) to route signals between analog blocks (e.g., comparators, DACs) and digital resources (e.g., timers, state machines), enabling user-defined LED drive topologies including buck, boost, and SEPIC configurations via firmware configuration.

Applications
| Architectural Linear Lighting | Commercial Downlight Arrays |
|---|---|

Use Value: Maintains Δu'v' < 0.003 over 0–60°C using per-channel current adjustment derived from ADC-measured Vf and thermal sensor data - no external color sensor required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar intelligent LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS31FL3731-QFLS4-TR | 18-channel LED driver with I²C interface; no integrated MCU, gate drivers, or current sense amps - requires external MOSFETs and control logic. | Best suited for low-power indicator lighting (≤20 mA/channel); lacks high-voltage capability and closed-loop current regulation. | Select when driving many low-current LEDs from 3.3 V/5 V rails with minimal firmware overhead. |
| MPQ3367GR-AEC1-P | 6-channel automotive-grade LED driver with integrated boost controller and 50 V switch; no programmable logic or ADC - fixed-function analog control. | Designed for automotive headlight modules; lacks I²C configurability and thermal derating logic for commercial lighting. | Select for ASIL-B compliant applications requiring AEC-Q100 qualification and high-temperature operation (−40°C to +125°C). |
Compared with IS31FL3731-QFLS4-TR and MPQ3367GR-AEC1-P, CY8CLED02D01-56LTXI uniquely integrates MCU control, high-voltage gate drivers, and closed-loop current sensing in a single 56-pin QFN - enabling firmware-defined LED topologies and adaptive thermal management not possible with fixed-function alternatives.

FAQ
Is CY8CLED02D01-56LTXI pin-compatible with other PowerPSoC LED driver variants?
Yes - it shares the identical 56-pin QFN footprint and pin mapping with CY8CLED04D01, CY8CLED03D01, and CY8CLED01D01 per TRM 001-46778 Section 1.1.5. Differences lie in channel count, memory size, and peripheral enablement, allowing drop-in replacement with firmware reconfiguration for reduced-channel designs.
Does this device support DALI or DMX512 protocol natively?
No - CY8CLED02D01-56LTXI does not include native DALI or DMX512 transceivers. However, its I²C interface and M8C CPU enable firmware implementation of DALI-2 command parsing and DMX512 frame reception using external UART or optocoupled isolation components.
What is the maximum continuous LED current per channel?
The device itself does not source LED current directly; it drives external N-MOSFETs. With appropriate MOSFET selection (e.g., 100 mΩ RDS(on)) and heatsinking, continuous channel currents up to 1.5 A are achievable - limited by PCB thermal design and gate driver thermal dissipation, not the IC's internal circuitry.
Can the internal oscillator replace an external crystal for timing-critical PWM?
Yes - the internal main oscillator (IMO) delivers ±2% accuracy across temperature and voltage, sufficient for LED dimming PWM where absolute timing precision is less critical than stability. For applications requiring <±0.1% jitter (e.g., synchronized multi-luminaire strobing), an external crystal or TCXO is recommended via the XTAL pins.
