描述

The MAX25608 12-switch matrix manager IC for automotive lighting applications includes a 12-switch array for bypassing individual LEDs in a single or dual string application. It features twelve individually controlled n-channel MOSFET switches rated for 14V with an on-resistance of 0.06Ω. A single current source can be used to power all the LEDs connected in series. Individual LEDs can be dimmed by turning on and off the bypass switches across each LED. The device can also be configured in two string applications with six switches in series per string. Each switch can be connected across one, two, or three LEDs in series. It also allows for parallel connection of two switches to bypass high-current LEDs. The IC also includes an internal charge pump that provides power for the gate drive for the LED bypass switches.

The MAX25608 features a serial peripheral interface (UART) for serial communication. Each switch can be turned fully on, fully off, or dimmed with or without fade transitions through the serial interface. The IC features open-LED protection as well as open and short LED fault reporting through the serial interface. The device is available in a 28-pin TSSOP package with exposed pad.
