• Manufacturer: Maxim Integrated Products, Inc.

0 to 16V, Quad, Hot-Swap Controller
with 10-Bit Current and Voltage Monitor
The MAX5961 provides detailed information about any
fault conditions that have occurred. Independent
FAULT_ outputs specifically indicate circuit-breaker
shutdown events, while an ALERT output is asserted
whenever a problem has occurred that requires atten-
tion or interaction.

If a fault event occurs (digital UV warning/critical, digital
OV warning/critical, or digital overcurrent warning) the
fault is logged by setting a corresponding bit in regis-
ters fault0, fault1, or fault2 (see Tables 47, 48, and 49).
Likewise, circuit-breaker shutdown events are logged in
register status0[7:0] (see Table 50).
