概述

Description

LP8860CQVFPRQ1 is a Texas Instruments automotive-grade LED driver IC (LP8860 family). It provides multi-channel, constant-current control to drive LED strings for automotive lighting (dash, indicators, exterior lighting, etc.). The device supports programmable current per channel, enables/disables control, and includes protection features such as fault/short-open LED detection and protection against adverse supply conditions. It is designed to withstand automotive environments and typically comes in a Pb-free QFN package with an automotive-grade (Q1) qualification level. For exact electrical specs, pinout, and programming details, consult the TI datasheet and application notes.

Package

QFN (Quad Flat No-Lead) package, RoHS-compliant.

Pinout

Pin count: 16 pins (QFN package).
Function: LP8860CQVFPRQ1 is a three-channel constant-current LED driver with an integrated boost regulator (LED current sinks) suitable for PWM dimming and LED protection.

Manufacturer

- Manufacturer: Lumissil Microsystems.
- What kind of company: A fabless semiconductor company that designs LED drivers and power-management ICs, relying on external foundries for fabrication.

Application

LP8860CQVFPRQ1 is a multi‑channel LED driver. Typical applications include:
- Automotive lighting (exterior and interior)
- LCD/LED display backlighting (TVs, monitors, signage)
- Architectural and decorative signage lighting
- Portable or battery-powered LED lighting requiring constant-current control and PWM dimming
