概述

Description

AL5809-40P1-7 is a compact LED driver IC designed to power LEDs with a constant current. It is a switch-mode regulator (current-control) in a 7-pin package, intended for small lighting modules, indicators, and display backlighting.
Key points:
- Provides stable, adjustable LED current from a range of input voltages.
- Supports dimming (PWM or analog, depending on implementation).
- Includes protection features such as overcurrent, short-circuit, and thermal protection.
- Typically offered in a small SOT-23-7 or similar package, with suffixes indicating variant and packaging (e.g., 40P1-7).
Applications include LED backlights, portable lighting, and compact signage. For exact electrical specs (input voltage range, maximum LED current, dimming interface), refer to the manufacturer’s datasheet or product brief for the specific AL5809-40P1-7 revision. If you share the manufacturer or a link, I can pull the precise details.

Package

40-pin package. The exact body/lead style (QFP/TQFP/SSOP, etc.) is defined in the AL5809-40P1-7 datasheet—please confirm via the manufacturer or distributor listing.

Pinout

Pin count: 40 pins.
Function: I don’t have the AL5809-40P1-7 datasheet in my data. Without the datasheet/manufacturer reference, I can’t specify the exact pinout or function of each pin. Please share a datasheet link or the manufacturer to extract the precise pinout and roles.

Manufacturer

I can’t identify the manufacturer from that part number alone. Please share a datasheet link or a distributor page (or specify the product type). With that, I can confirm the exact manufacturer and describe the company (e.g., fabless semiconductor, analog IC maker, etc.).

Application

Common application areas for AL5809-40P1-7 (LED driver IC) include:
- Constant-current LED driving for LCD backlights, signage, and displays
- General/architectural lighting (downlights, lamp retrofit, decorative lighting)
- Automotive lighting and interior illumination
- Portable or battery-powered LED lamps with PWM dimming

Equivalent

I can’t identify AL5809-40P1-7 reliably without the datasheet. It may be a power-management or LED-driver IC. To give exact equivalents, please share the part’s function and key specs (input/output voltage, current, package, temp range). If unavailable, you can: 1) search DigiKey/Mouser/Octopart for AL5809 crossrefs by function and package; 2) check the manufacturer’s cross-reference; 3) compare pinout/features with candidates from TI, Analog Devices, RichTek, etc.
