Product details
Overview
CY8CLED01D01-56LTXQT from Infineon Technologies (formerly Cypress Semiconductor) is a PowerPSoC® intelligent LED driver IC integrating an M8C 8-bit microcontroller 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 CY8CLED01D01-56LTXQT datasheet, CY8CLED01D01-56LTXQT pinout, CY8CLED01D01-56LTXQT application, or CY8CLED01D01-56LTXQT equivalent, this device is selected for embedded LED control requiring mixed-signal programmability, on-chip power regulation logic, and direct high-side FET gate drive capability - not general-purpose MCU use.
Technical Context
The CY8CLED01D01-56LTXQT implements a configurable mixed-signal architecture where the M8C CPU executes firmware to manage LED brightness, thermal foldback, and fault reporting via I²C. Its analog system includes dedicated current sense amplifiers (gain = 20 V/V), 12-bit SAR ADCs, and hysteretic controllers that directly modulate external N-channel MOSFETs without external compensation components.
Digital resources include programmable digital blocks for PWM generation, decimation filtering, and I²C slave interface (up to 400 kHz), while the power subsystem integrates gate drivers capable of 200 mA sink/source per channel with 25 ns propagation delay and 10 ns rise/fall times - enabling precise timing-critical LED switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | M8C 8-bit RISC CPU running at up to 24 MHz - enables real-time LED control loop execution with <10 µs interrupt latency. |
| LED Channels | 4 independent constant-current channels - supports multi-zone architectural lighting with per-channel dimming and fault isolation. |
| PWM Resolution | 12-bit (4096 steps) - provides smooth, flicker-free dimming across 0.1%–100% intensity range. |
| Supply Range | 5.5 V to 28 V VDD - allows direct operation from 12 V/24 V industrial LED power rails without pre-regulation. |
| Gate Drive | High-speed N-channel MOSFET drivers (200 mA sink/source, 25 ns delay) - eliminates need for external driver stages in buck/boost LED topologies. |
| Current Sense | Integrated CSA with 20 V/V gain and ±1% offset - enables accurate LED current regulation down to 10 mA with single-shunt configuration. |
| I²C Interface | Standard/fast-mode (100/400 kHz) slave-only - permits host MCU or lighting controller to configure dimming profiles and read fault status. |
Pinout & Package
Package: 56-pin QFN (8 mm × 8 mm, 0.5 mm pitch), thermally enhanced with exposed pad for LED driver thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply input | Accepts 5.5–28 V; powers digital core, analog blocks, and gate drivers - requires local 10 µF ceramic bypass. |
| VSS | Digital/analog ground reference | Common return for all circuits; must be low-impedance connection to minimize noise coupling into current sense path. |
| GD0–GD3 | Gate drive outputs | Four independent high-current (200 mA) push-pull outputs for driving external N-MOSFET gates in LED string switches. |
| CS0–CS3 | Current sense inputs | Differential inputs to integrated CSAs; connect to shunt resistors in LED cathode paths for closed-loop current regulation. |
| SCL/SDA | I²C serial interface | Two-wire bus interface for configuration and monitoring; supports standard/fast-mode timing with internal pull-ups disabled by default. |
| RESET | Active-low reset input | Asynchronous reset signal; asserted low resets CPU and peripherals - compatible with open-drain host reset generators. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Analog System | Configurable current sense amplifiers, comparators, and hysteretic controllers enable custom LED regulation algorithms without external op-amps or comparators. |
| Integrated Gate Drivers | Four 200 mA drivers with 25 ns propagation delay eliminate discrete driver ICs and reduce board space in multi-string LED drivers. |
| 12-bit PWM Dimming | Hardware-accelerated PWM generation with independent period/resolution per channel ensures synchronized, jitter-free dimming across all strings. |
| Thermal Foldback Protection | On-die temperature sensor triggers automatic current reduction above 125°C - prevents thermal runaway without external circuitry. |
| I²C Slave Configuration | Register-mapped I²C interface allows runtime adjustment of LED current targets, PWM frequency, and fault thresholds from host controller. |

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 or gate drivers - requires external FETs and microcontroller. | Best for low-power indicator lighting (≤25 mA/channel); lacks high-voltage capability and thermal protection for mains-connected LED loads. | Select when scaling to >4 channels with simple on/off or basic PWM control - not for constant-current regulation above 100 mA. |
| TPS92692QPWPRQ1 | Dedicated automotive LED controller with integrated 65 V boost controller; no programmable logic or multi-channel PWM flexibility. | Designed for automotive headlamp applications with AEC-Q100 qualification; lacks I²C configurability and thermal foldback algorithm customization. | Select for ASIL-B compliant vehicle lighting where safety certification and high-voltage boost integration outweigh programmability needs. |

FAQ
Is CY8CLED01D01-56LTXQT pin-compatible with other PowerPSoC LED driver variants?
Yes - it shares the same 56-pin QFN package and pinout with CY8CLED02D01, CY8CLED03D01, and CY8CLED04D01. Differences lie in configured analog/digital resources and channel count, but PCB layout and power delivery are identical across the D0x series.
Does this device require external programming hardware?
No - it supports in-system programming via SWD interface using standard Cypress/Infineon kits (e.g., KitProg3). Firmware can be updated in the field through I²C-hosted bootloader without removing the IC from the board.
What thermal management is required for full-load operation?
At maximum 28 V input and 4 × 150 mA LED current, junction temperature must be maintained below 125°C. A 4-layer PCB with 2 oz copper, thermal vias under the exposed pad, and ≥2 cm² copper pour reduces θJA to ≤35°C/W - enabling continuous operation at 70°C ambient.
Can the current sense amplifiers measure bidirectional current?
No - the integrated CSAs are unidirectional, optimized for cathode-side shunt measurement in high-side switch configurations. They accept only positive differential input voltage (0–100 mV) referenced to VSS, with fixed 20 V/V gain and no polarity reversal capability.
