MAX8555A Evaluation Kit

General Description

Features

♦ 1+1 Redundant System for a 1.5V Bus

(0.5V to 3.3V with Modifications)

♦ Eliminates ORing Diode Power Dissipation

♦ Reverse-Current Detection

♦ Adjustable Undervoltage Threshold

(Configured to 0.75V)

The MAX8555A evaluation kit (EV kit) demonstrates the

functionality of the MAX8555A ORing MOSFET con-

troller, which provides redundancy and fault isolation to

highly reliable power systems. The EV kit is configured

for 1.5V operation, but can also be modified to operate

in 0.5V to 3.3V power systems.

During startup, the EV kit monitors the voltage differ-

ence between the power supplies VIN1 or VIN2 and a

system power bus VOUT. Once the voltage difference

is less than 50mV (typ), the MAX8555A turns on the two

associated ORing MOSFETs, connecting the power

supply to the system power bus. Once the MOSFETs

are fully on, the EV kit circuit monitors the supply cur-

rent and voltages to protect against undervoltage

(UVP), overvoltage (OVP), and reverse-current fault

conditions. PC board pads for fault output signals are

provided for circuit monitoring.

♦ Adjustable Overvoltage Threshold

(Configured to 2V)

♦ FAULT Output Status Indicator

♦ Adjustable Soft-Start

♦ Supports Up to 20A of Load Current

♦ Surface-Mount Construction

♦ Fully Assembled and Tested
