• Manufacturer Part Number: max5965a
• Description: High-power, Quad, Monolithic, Pse Controllers For Power Over Ethernet
• Manufacturer: Maxim Integrated Products, Inc.

Writing a 1 to CLR_INT (Table 23) clears all the event
registers and the corresponding interrupt bits in regis-
ter R00h. Writing a 1 to RESET_P_ turns off power to the
corresponding port and resets only the status and
The ID register (Table 24) keeps track of the device ID
number and revision. The MAX5965A/MAX5965B’s

event registers of that port. After execution, the bits
reset to 0. Writing a 1 to RESET_IC causes a global
software reset, after which the register map is set back
to its reset state. A reset sets R1Ah = 00h.
