0V to 16V, Dual Hot-Swap Controller with 10-Bit
Current and Voltage Monitor and 4 LED Drivers
All voltage measurement values are compared with the
contents of minimum- and maximum-value registers,
and if the most recent measurement exceeds the stored
maximum or is less than the stored minimum, the corre-
sponding register is updated with the new value. These
