概要

Description

MAX16814AUP/V+T is Maxim Integrated’s (now Analog Devices) high‑voltage LED driver/power‑management IC designed for constant‑current LED lighting. It combines a switching regulator and current‑sense feedback to drive LED strings efficiently over a wide input voltage range, with dimming options (PWM or DC) and programmable LED current via an external sense resistor. It includes protection features such as overcurrent, overvoltage, thermal shutdown, and short‑circuit protection. The AUP suffix indicates automotive/industrial‑grade relevance, and V+T denotes specific packaging/tape‑and‑reel options for manufacturing. Typical applications include automotive exterior lighting, display backlights, signage, and other high‑efficiency LED lighting where reliable current regulation is needed. For exact specifications (input range, max LED current, number of channels if applicable, dimming interface), refer to the MAX16814AUP/V+T datasheet and product page.

Features

Here are the typical features of MAX16814AUP/V+T (as in the MAX16814 family). For exact numbers, please consult the datasheet.
- High-efficiency buck regulator controller (synchronous/async options)
- Wide input voltage range suitable for many dc-dc apps
- Adjustable output via resistor divider (fixed versions available)
- Current‑mode PWM with cycle-by-cycle current limiting
- Programmable switching frequency; may support synchronization
- Start-up control with soft-start
- Protection: UVLO, OVP, overcurrent/short-circuit protection, thermal shutdown
- Enable/shutdown input
- Power-good/status indication
- RoHS-compliant packaging; AUP variant with Tape & Reel (+T option) available
Note: exact electrical specs (ranges, timing, and integration level) vary by variant; verify with the current Maxim datasheet for MAX16814AUP/V+T.

Package

Package type: 16‑pin TQFN (3×3 mm) with an exposed pad. +T indicates Tape & Reel packaging; AUP is the package family designation.

Pinout

Pin count: 8 pins (SO-8/TDFN variants).
Function: High-voltage buck regulator/LED driver controller with constant-current output (drives LED strings with adjustable/set current, typically for automotive/applications). Integrates switching regulator control and feedback for LED current regulation.

Manufacturer

- Manufacturer: Maxim Integrated (MAXIM). It is a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (e.g., power management, LED drivers, data converters). In 2021, Maxim was acquired by Analog Devices, so MAXIM products are now under Analog Devices.

Application

Applications of MAX16814AUP/V+T:
- LCD backlight drivers
- Automotive lighting (exterior/interior)
- Signage and display lighting
- Architectural/decorative and high-brightness general lighting
- Portable/battery-powered LED lighting with dimming control

Equivalent

I need the function and key specs to give accurate equivalents. Please confirm what MAX16814AUP/V+T does (DC-DC regulator, LED driver, battery charger, etc.) and provide core specs (input/output voltage, current, package). Then I’ll supply concise cross‑references (TI, Analog Devices, ON Semiconductor, etc.).
