• Description: 0 To 16v, Quad, Hot-swap Controller With 10-bit Current And Voltage Monitor
• Manufacturer: Maxim Integrated Products, Inc.

0 to 16V, Quad, Hot-Swap Controller
with 10-Bit Current and Voltage Monitor
All current measurement values from the ADC are con-
tinuously compared with the contents of minimum- and
maximum-value registers, and if the most recent mea-
surement exceeds the stored maximum or is less than
the stored minimum, the corresponding register is

updated with the new value. These “peak detection”
registers are read/write accessible through the I
interface (Tables 13–16). The minimum-value registers
are reset to 0x3FF, and the maximum-value registers
are reset to 0x000. These reset values are loaded upon
startup of a channel or at any time as commanded by
register peak_log_rst (Table 36).
