IRS2052M
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=10V, VCC=VCC2=12V, COM2=COM and VB-
VS=12V. All voltage parameters are absolute voltages referenced to COM; all currents are defined positive
into any lead.

†
Logic operational for Vsn equal to –5V to +200V. Logic state held for Vsn equal to –5V to –VBSn
.
††
Nominal voltage for VREF is 5.1V. IOREF of 0.3 – 0.8mA dictates total external resistor value on VREF
to be 6.3k to 16.7k ohm.
†††
GND input voltage is limited by IIN-n.
†††† Vss ramps up from 0V to 200V.
