7 Circuit Performance for EFT Tests

The TPS2662 device has integrated back to back MOSFETs which provide overvoltage protection, reverse input polarity protection, reverse output polarity protection and fast reverse current blocking to achieve a Criteria-A performance for EFT tests. Table 7-1 summarizes the results for circuit performance for EFT protection with TPS2662.

Table 7-1 Circuit perfprmance with TPS2662 for EFT protection
EFT level Voltage (kV) Pass/Fail on input (VIN) Pass/Fail on output (VOUT)
1 ±0.5 Pass with Criteria-A performance(1) Pass with Criteria-A performance(1)
2 ±1 Pass with Criteria-A performance(1) Pass with Criteria-A performance(1)
3 ±2 Pass with Criteria-A performance(1) Pass with Criteria-A performance(1)
