MAX16814AUP/V+T

MAX16814AUP/V+T is a high‑voltage LED‑driver IC from Maxim Integrated. It provides constant‑current drive for LED strings from a wide input supply (ideal for automotive/industrial backlighting and display backlights). The device typically integrates a switching regulator/MOSFET and uses an external sense resistor to regulate LED current, with adjustable current and dimming options (PWM or analog). It includes protection features such as undervoltage, overcurrent, and thermal shutdown, and comes in compact packages with AUP and V+T suffixes (and tape & reel packaging). Applications include multi‑string LED backlights, sign lighting, and automotive lighting. For exact specifications—number of channels, current range, input voltage range, dimming interface, and pinout—refer to the MAX16814AUP/V+T datasheet and related application notes.

Pin count: 28 pins (AUP variant; V+T denotes Tape & Reel packaging). Function: High‑voltage, current‑mode PWM controller for DC‑DC converters with an integrated power MOSFET (used in buck/boost applications) featuring protections such as soft‑start, current limit, and undervoltage.

- Manufacturer: Maxim Integrated.
- What kind of company: An American fabless semiconductor company that designs and sells analog and mixed-signal integrated circuits (e.g., power-management, interface, timing). It was acquired by Analog Devices in 2021 and is now part of ADI.
