MAX25605 Six-Channel Sequential LED Controller

Analog Devices MAX25605 Six-Channel Sequential LED Controller implements a sequential turn function or any other sequential light animation without the use of a microcontroller or software. The Analog Devices MAX25605 integrates six cascoded low R_DSON N-channel MOSFETs suitable for LED lighting applications up to 750mA. Each switch supports up to three series LEDs per switch. The entire LED string supports voltages up to 60V. The N-channel MOSFETs are divided into two groups of three, allowing a single device to sequence either one or two strings of LEDs. Integrated gate drivers and level shifters for the switches are supplied by an internal charge-pump regulator, supporting buck-boost and boost-to-battery applications, in addition to ground-referenced LED driver topologies.
