Critical loads often employ parallel-connected power

supplies with redundancy in order to enhance system

reliability. The MAX8535/MAX8536/MAX8585 are highly

integrated but inexpensive MOSFET controllers that pro-

vide isolation and redundant power capability in high-reli-

ability systems. The MAX8535/MAX8585 are used in 12V

systems, and have an internal charge pump to drive the

♦ Eliminates ORing Diode Power Dissipation and

gates of the n-channel pass elements to V + 10V. The

MAX8536 is used in 3.3V and 5V systems, with a charge-

pump output of V + 5V.

Highly Reliable Systems

MOSFETs a re turne d on. The MAX8535/MAX8536/

MAX8585 feature a dual-purpose TIMER input. A single

external resistor from TIMER to ground sets the turn-on

speed of the external MOSFETs. Optionally, the TIMER

input can be used as a logic-enable pin. Once the

device is turned on, the MAX8535/MAX8536/MAX8585

monitor the load, protecting against overvoltage, under-

voltage, and reverse-current conditions.
