MAX16805ATP規(guī)格書詳情

General Description

The MAX16805/MAX16806 LED drivers eliminate the need for microcontrollers or switch-mode converters. An EEPROM-programmable LED current-sense reference simplifies production by using one sense resistor to set the LED current for all LED bins. A dual-mode DIM pin and an onboard 200Hz ramp generator allow for PWM dimming with an analog or PWM control signal. The analog control signal at dimming input DIM allows for the theater dimming effect to be implemented. Fast turn-on/-off times ensure a wide-range PWM operation, while waveshaping circuitry minimizes EMI.

Features

● EEPROM or I2C Dynamically Programmable:

??? ? LED Current Foldback for High Input Voltage

● On-Board 200Hz Ramp Generator Eliminates the Need for μC PWM Signal

● Flexible Analog or PWM Control for PWM or Theater Dimming

● Wetting Current and Debounce for Momentary Switch (MAX16806)

● 5.5V to 40V Input with Up to 39V Output Capability

● 35mA to 350mA Adjustable LED Current

● Waveshaping Minimizes EMI During Dimming

● Output Short-Circuit and Overtemperature Protection

● -40°C to +125°C Operating Temperature Range

Applications

● Emergency Vehicle Warning Lights

● Navigation and Marine Indicators
