Description

The IR5001STRPBF is a universal high-speed controller and N-channel power MOSFET driver designed for Active ORing and reverse polarity protection applications. It is suitable for both input ORing in carrier-class telecom equipment and output ORing in redundant DC-DC and AC-DC power supplies. The IR5001S can quickly switch the Active ORing FET off in case of a short-circuit failure, minimizing voltage sags on the redundant DC voltage.

Specifications and features

- Controller/driver IC in an SO-8 package - Implementation of Active ORing/reverse polarity protection using N-channel Power MOSFETs - 130ns typical turn-off delay time - 3A peak turn-off gate drive current - Asymmetrical offset voltage of the internal high-speed comparator prevents potential oscillations at light load - Ability to withstand continuous gate short conditions - Integrated voltage clamps on both comparator inputs allow continuous application of up to 100V - Option to be powered either directly from 36-75V universal telecom bus (100V max) or from an external bias supply and bias resistor - Input/Output pins to determine the state of the Active ORing circuit and power system redundancy

Application Scenarios

- -48V/-24V Input Active ORing for carrier-class communication equipment - Reverse input polarity protection for DC-DC power supplies - 24V/48V output active ORing for redundant AC-DC rectifiers - Low output voltage (12V, 5V, 3.3V...) active ORing for redundant DC-DC and AC-DC power supplies - Active ORing of multiple voltage regulators for redundant processor power

Comparison

- Universal high-speed controller and N-channel power MOSFET driver - Suitable for both input ORing and output ORing applications - Quick turn-off delay of only 130ns - Integrated voltage clamps for continuous application of up to 100V - Ability to withstand continuous gate short conditions - None mentioned in the description.
