• Manufacturer Part Number: max5961
• Description: 0 To 16v, Quad, Hot-swap Controller With 10-bit Current And Voltage Monitor
• Manufacturer: Maxim Integrated Products, Inc.

When an overcurrent event causes the MAX5961 to
shut down a channel, a corresponding open-drain
FAULT_ output alerts the system. Figure 3 shows the
