Product details

Overview

AL5887JAZW52-13 from Diodes Incorporated is a 36-channel I²C/SPI RGB LED driver IC with 12-bit per-channel PWM, 70mA max sink current per channel, ±2% current accuracy (7–70mA), and integrated open/short fault detection - deployed in smart home appliance status lighting and EV charging station indicator arrays.

For engineers reviewing the AL5887JAZW52-13 datasheet, AL5887JAZW52-13 pinout, AL5887JAZW52-13 application, or AL5887JAZW52-13 equivalent, key selection criteria include programmable bank control (A/B/C), 30kHz noise-free PWM, thermal-aware current scaling, and dual-protocol interface flexibility with hardware address pins for multi-device I²C daisy-chaining.

Technical Context

The AL5887 operates as a digitally controlled constant-current LED sink array with independent 12-bit PWM generators per channel, supporting both I²C (400kHz, up to 4 devices via ADDR0/ADDR1) and SPI (4MHz, INT_SEL = HIGH) protocols. It integrates pre-UVLO warning, OTP with pre-warning, and per-channel open/short diagnostics routed to an open-drain FAULT pin.

Each of its 36 OUT pins delivers up to 70mA with <2% matching across channels at 7–70mA, set globally by R_SET and scaled via 6-bit global dimming plus per-channel brightness/color-mix registers. The device supports logarithmic or linear brightness curves and PWM phase shifting to suppress beat frequencies.

Key Specifications

Parameter	Value and Actual Design Meaning
Interface	I²C (400kHz default) or SPI (4MHz); selected via INT_SEL pin - enables firmware-compatible migration between bus types without PCB change.
LED Channels	36 independent constant-current sinks - supports up to 12 RGB modules (3 channels/module) with bank A/B/C software grouping.
PWM Resolution	12-bit (4096 steps) at 30kHz - eliminates audible noise while enabling smooth color transitions in human-visible lighting effects.
Current Accuracy	±2% (7–70mA), ±3.5% (1–7mA) - ensures consistent luminance across modules without per-unit calibration.
Supply Range	2.7V to 5.5V V_CC; OUT pins tolerate up to 5.5V - compatible with 3.3V and 5V microcontroller I/O domains and common DC-DC rails.
Fault Detection	Per-channel open/short detection + pre-OTP/UVLO warnings - reduces system-level diagnostic firmware overhead and improves field reliability.
Quiescent Current	1μA shutdown (EN low >25ms), 15μA power-saving mode (EN high, all LEDs off >30ms) - extends battery life in always-on IoT indicators.

Pinout & Package

Package: W-QFN6060-52/SWP (Type A1), 6mm × 6mm, wettable flank, thermal exposed pad.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Primary power supply input	Supplies internal logic and gate drivers; must be decoupled locally to support transient current demands of 36-channel switching.
GND	Ground reference	Common return for logic, analog, and power paths; connects to thermal pad for heat dissipation and EMI control.
OUT0–OUT35	LED current sink outputs	36 individually controllable constant-current outputs; each drives cathode of external LED with up to 70mA and 5.5V compliance voltage.
IREF	Global current reference input	Connects to external R_SET resistor to define full-scale current for all 36 channels simultaneously.
INT_SEL	Interface selection control	High = SPI mode (SPISDO/SPISDA/SPICS/SPISCL active); Low = I²C mode (SDA/SCL active) - sets physical layer at power-up.
FAULT	Open-drain fault indicator	Asserts low on any detected fault (open/short LED, UVLO, OTP); requires external pull-up for interrupt-driven host response.
RSTn	Active-low hardware reset	Asynchronous reset that clears all registers and reinitializes PWM state - used for recovery after brown-out or configuration error.
EN	Enable control input	Active-high enable; asserts shutdown mode (<1μA) when held low >25ms - enables system-level power gating.

Key Features

Feature	Design Value
Three programmable banks (A/B/C)	Enables grouped control of RGB modules (e.g., Bank A = front panel, Bank B = side indicators) without register-by-register writes.
PWM phase shifting	Reduces peak current demand and conducted EMI by staggering PWM edges across channels - critical for compact PCB layouts.
Auto-increment register access	Allows writing brightness values to 36 channels in one I²C/SPI transaction - cuts firmware execution time by >70% vs. individual writes.
Per-channel color-mixing register	Stores independent red/green/blue intensity weights per channel - enables precise white-point tuning and dynamic hue adjustment per LED.
Individual channel fault masking	Allows disabling fault reporting for known non-critical channels (e.g., unused indicators), preventing false system alerts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar RGB LED driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLC59731 (Texas Instruments)	12-channel, 16-bit PWM, SPI-only, no fault detection, 25mA/channel max	Limited to smaller LED arrays; lacks open/short diagnostics and thermal warning	Choose for cost-sensitive, low-channel-count designs where diagnostics are handled externally.
IS31FL3733 (Lumissil)	28-channel, I²C-only, 32mA/channel, integrated dot correction, no PWM phase shift	Higher channel density but lower current drive; no hardware bank grouping or phase control	Prefer when precise per-LED grayscale correction is required over thermal-aware current scaling.

Compared with TLC59731 and IS31FL3733, the AL5887JAZW52-13 uniquely combines 36-channel drive, 70mA capability, real-time fault diagnostics, and dual-protocol flexibility - making it optimal for thermally constrained, safety-aware RGB lighting in industrial and transportation equipment.

FAQ

What is the maximum allowable voltage on the OUT pins?

The OUT pins support a maximum voltage of 5.5V, enabling direct connection to common 5V LED strings without external level-shifting. This rating is independent of VCC and applies under all operating conditions, including fault states. Exceeding 5.5V risks permanent damage to the internal current-sink transistors.

How does the AL5887 handle thermal overload?

The AL5887 integrates overtemperature protection (OTP) with a pre-OTP warning flag. When die temperature exceeds 140°C, the pre-warning activates the FAULT pin; at 155°C, OTP triggers automatic shutdown of all channels. Both thresholds are factory-trimmed and do not require external components or configuration.

Can multiple AL5887 devices share the same I²C bus?

Yes - two hardware address pins (ADDR0, ADDR1) allow up to four AL5887 devices on a single I²C bus. Each device responds to a unique 7-bit slave address (0x60–0x63). Broadcast addressing also enables simultaneous register writes across all connected devices without individual addressing overhead.

Is the AL5887JAZW52-13 qualified for automotive use?

No - the AL5887JAZW52-13 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AL5887Q) with PPAP support, IATF 16949 manufacturing, and extended temperature validation. For automotive applications, contact Diodes directly to evaluate qualified alternatives with full change control documentation.
