KTA1170 Dual MOSFET Bridge Rectifier

Kinetic Technologies bridge rectifiers are designed to rectify independent DC channels into a single output

Image of Kinetic Technologies KTA1170 Dual MOSFET Bridge RectifierThe KTA1170 from Kinetic Technologies is a single-chip, highly integrated solution for voltage rectification on power over ethernet (PoE) powered devices. Applications include voice over IP (VoIP) phones, wireless LAN access points, security cameras, WiMAX terminals, point-of-sale (POS) terminals, RFID readers, thin clients, and notebook computers.

The KTA1170 is a dual ideal diode bridge designed to rectify independent DC channels into a single output. The KTA1170 can sense the input channels from |IN1-IN2| or |IN3-IN4| and connect them to the output with the correct polarity. KTA1170 can also sense the input channels from |IN1-IN2| and |IN3-IN4| together and connect them to the output with the correct polarity. A very common application is an IEEE 802.3af/at/bt-compliant powered device.
