SLDS231 August 2018 PGA305
PRODUCTION DATA.
The PGA305 fault-monitoring circuits monitor faults either at power up or periodically. Table 13 shos the fault-detection timing.
FAULT | POWER UP OR RUN TIME | MINIMUM TIME AFTER FAULT OCCURS | MAXIMUM TIME AFTER FAULT OCCURS |
---|---|---|---|
Digital-compensation execution-timing error | Run time | 500 ms | — |
Digital-compensation checksum error | Run time | 500 ms | — |
EEPROM is corrupted or EEPROM CRC = 0 | Power up only (EEPROM is accessed only at power up) | N/A | N/A |
Power supply and signal chain errors | Run time | 8 ms | 16 ms |
