NOTES:

Note 1: The diode, D, helps discharge the capacitor quickly when V DD powers down.

• 2: R1 = 1 k  to 10 k  will limit any current flowing into RESET from the external capacitor, C, in the event of RESET pin breakdown due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS).

NOTES:

Note 1: This parameter is periodically sampled and not 100% tested.
