Keywords:IRS2166D IR2166 comparison? HVIC IR2166? IRS2166D difference?

The IRS2166D replaces IR2166 HVIC advantageously with the following enhancements:

? Improved VBUS regulation voltage tolerance;
? Improved frequency tolerance;
? Increased SD pin shutdown voltage threshold hysteresis;
? Changed EOL pin internal 2V bias to a +/-10?A OTA;
? Internal bootstrap MOSFET;
? Undervoltage lockout on the floating supply;
? Improved EOL pin shutdown threshold tolerance.

It is based on the same core design (but with the addition of the integrated bootstrap functionality) and is pin-to-pin compatible, allowing minimum changes to the previous design. This application note describes the differences between the IR2166 HVIC and the IRS2166D.
