Digitally controlled power multiplexing and monitoring system
PMP5927: PMP5927 is an I2C controlled 1:7 Power Mux and Monitoring System for DC distribution systems from 9 to 80 V. It is well suited for distributing power to TMAs (Tower Mounted Antennas), LED Arrays, and other DC systems needing sequencing, circuit protection, and monitoring via an I2C interface. With the built in USB to I2C converter, the PMP5927 can be easily used with only a USB to Mini USB cable and the downloadable GUI.
