14) Noise Filter on RST_TH and OV_TH Terminals (C9, C10)
These capacitors may be required in some applications to filter the noise on RST_TH and OV_TH pins. Typical
capacitor values for RST_TH and OV_TH pins are between 10 pF to 100 pF for total resistance on
RST_TH/OV_TH divider of less than 200 kΩ. See discussion on Noise Filter on RST_TH and OV_TH Terminals.
