High current draw following a negative current injection on PA2 pin

Revisions Affected

Rev C

Details

A negative current injection into the PA2 pin can lead to an unexpected and sustained high current draw in the device.

Workaround 1

If the PA2 is used in ROSC mode (100kΩ resistor is populated between ROSC and VSS), no additional handling is required.

Workaround 2

Place a series resistor with a typical value of 100 Ω between the PA2 pin and any connected circuit, with the resistor placed near to the PA2 pin. This resistor is intended to limit fast transients seen at the PA2 pin and is sufficient to prevent this scenario from occuring.

Workaround 3

Avoid using the PA2 pin and use an alternate pin instead.
