产品详情
The MAX25608/MAX25608B/MAX25608C 12-switch matrix manager ICs for automotive lighting applications include a 12-switch array for bypassing individual LEDs in a single- or dual-string application. They feature 12 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 of the LEDs connected in series. Individual LEDs can be dimmed by turning on and off the bypass switches across each LED. The devices can also be configured in dual-string applications with six switches in series per string. Each switch can be connected across one, two, or three LEDs in series. These devices also allow for parallel connection of two switches to bypass high-current LEDs. The ICs also include an internal charge pump that provides power for the gate drive for the LED bypass switches.
The MAX25608/MAX25608B/MAX25608C feature a serial interface (UART) for serial communication. The MAX25608/MAX25608C can be used in full-duplex applications, and the MAX25608B can be used in half-duplex applications, such as with CAN transceivers. The MAX25608 has spread spectrum enabled on the charge pump clock, and the MAX25608B/MAX25608C have spread spectrum disabled on the charge pump clock. Each switch can be turned fully on, fully off, or dimmed with or without fade transitions through the serial interface. The ICs feature open-LED protection as well as open- and short-LED fault reporting through the serial interface. The devices are available in a 28-pin TSSOP package with exposed pad.
