IRS2092
Recommended Operating Conditions
For proper operation, the device should be used within the recommended conditions below. The Vs and COM offset ratings
are tested with supplies biased at VAA-VSS=10 V, VCC=12 V and VB-VS=12 V. All voltage parameters are absolute voltages
referenced to COM; all currents are defined positive into any lead.

Note 1: Logic operational for Vs equal to –5 V to +200 V. Logic state held for Vs equal to –5 V to –VBS.
Note 2: Nominal voltage for VREF is 5.1 V. IOREF of 0.3 – 0.8 mA dictates total external resistor value on VREF to be 6.3 kꢀ to
16.7 kꢀ.
Note 3: GND input voltage is limited by IAAZ and ISSZ
Note 4: VSS ramps up from 0 V to 200 V.
.
Note 5: Output logic status may not respond correctly if input pulse width is smaller than the minimum pulse width.
