• Manufacturer Part Number: max5961
• 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
The voltage at the load (MON_ inputs) is sampled by
the internal ADC. The MON_ full-scale voltage for each
channel can be set to 16V, 8V, 4V, or 2V by writing to
Table 19. ADC Voltage Conversion Result Register Format (High-Order Bits)
