Figure 9-11 Chassis Ground Reference RISO1 Selection
In order to protect the TPSI2240-Q1, RISO1 must be sized to limit the current in an overvoltage condition. The amount of resistance required to protect the TPSI2240-Q1 depends on the amount of overvoltage applied. For example, during a dielectric withstand voltage test (HiPot) of 3500V for 60 seconds, the S1 to S2 voltage will be clamped to 1300V (VAVA minimum) by the TPSI2240-Q1 and the RISO1 resistance required to keep the current under 1mA would be 2.2MΩ.
