The IR2277S

The IR2277S is a high voltage current sensor, best suited for AC motor drive applications. An integrated

adaptive filter provides superior ripple rejection on phase current measurement being synchronous with

PWM carrier (SYNC input). A ratiometric analog output is provided by each device to the controller in a

controllers which do not use A/D converters for current measurement. Over current detection is also

available via open collector OC pins.

The stacked structure of HVIC demo boards

IRCS2277S demo board is fully compatible with

standard

pin

out

of

IRMD2214xSS

and

IRMD22381Q demo boards.

The HVIC demo boards are structured to work

together on top of an ECONO2 power module or

a PowerPCB.

Important Notice

IRCS2277S demo board is supplied with a tentative Bill of Material suitable for a generic 380V generic 3-

phase motor drive application. The BOM presented on page 12 provides just a suggestion.

It is strongly recommended to customize the demo board to fit the application requirements for the power

level that has been chosen.
