12. Errata
Issue: The internal fault counter will be reset when updating the Configuration Register, the T
HIGH
Limit Register, or the T
LOW
Limit Register.
Workaround: None. The current version of the device was intentionally designed to operate this way; however,
it has been discovered that resetting of the fault counter when updating the registers is not
preferred.
Resolution: The operation of the device will be changed with a new revision of the device (AT30TS75A) so
updating the Configuration Register, the T
HIGH
Limit Register, or the T
LOW
Limit Register will not
affect the internal fault counter. See the AT30TS75A datasheet.
12.1 ALERT Pin
Issue: Depending on Power supply Ramp time, the ALERT pin may not be configured in the
proper state to be a true open drain.
Workaround: The ALERT pin must be pulled-high using an external pull-up resistor even when it is not used.
Care must also be taken to prevent this pin from being shorted directly to ground without a resistor
at any time whether during testing or normal operation.
Resolution: The operation of the ALERT Pin will be changed with a new revision (AT30TS75A) of the device
so it is a true open drain. See the AT30TS75A datasheet.
12.2 ALERT Pin State
Issue: When switching between Comparator and Interrupt modes (or vice versa) while the ALERT
pin is active, the device will not retain its active alert state and will automatically deassert
the ALERT pin.
Workaround: None.
Resolution: The operation of the ALERT pin will be changed with a new revision of the device (AT30TS75A) so
it will properly retain the ALERT pin status when switching modes. See the AT30TS75A datasheet.
