Product Summary
The NCR90C26 is a dual feed active-ORing programmable hot swap controller. The NCR90C26 drives external power MOSFET switches that connect the supply to the load while reducing in-rush current and providing over-current protection. Its applications include Telecom Hot-Swap Card - AdvancedTCATM, Network Processors, Power-on Ethernet, IEEE 802.3af.
