MCHPHV96001-E/NFA
Overview
The HV96001-E/NFA is a secondary-side LED controller designed for high-brightness lighting applications. It features a micro-interface for advanced control, supporting both deep PWM dimming and linear analog dimming across a wide 8V to 60V input range. The device integrates essential protections including overvoltage, overcurrent, and short-circuit detection with an auto-retry delay mechanism.
Why Choose This Part
This controller offers versatile dimming options with a low 1.5 microampere sleep current for high energy efficiency. Its integrated fault recovery logic, including stuck-at-zero detection for the DIM signal, enhances system reliability without requiring complex external supervisory circuits.
Applications
Getting Started
Designers should begin by selecting a timing capacitor to set the desired auto-retry delay for fault recovery. Evaluation can be performed by integrating the 16-VQFN package into a flyback or boost topology and interfacing the PWM input with a standard 5V microcontroller logic signal.
