MAX8555AEUB

OR Controllers, Ideal Diodes Overview

The MAX8555AEUB+ is a low-cost, high-reliability ORing MOSFET controller manufactured by Analog Devices Inc./Maxim Integrated. Designed for power distribution applications, it operates with an input voltage range of 0.5V to 3.3V and supports a supply voltage between 3V and 5.5V. The device features a single driver output capable of sourcing 30uA, with a fall time of 200ns. It functions as a gate driver for high-side and low-side configurations, consuming 3.3mA of operating current. The component is housed in a UMAX-10 surface-mount package and operates within a temperature range of -40°C to +85°C.

OR Controllers, Ideal Diodes Feature Summary

• Implements ORing logic using external MOSFETs to prevent reverse current flow and ensure load isolation
• Provides high-reliability power path management with low-cost implementation
• Supports both high-side and low-side driver configurations for flexible system design

OR Controllers, Ideal Diodes Applications

• Redundant power supply systems requiring automatic switchover
