... V CC point. RESET is asserted until V operating level and stabilizes. Four industry standard Vtrip thresholds are available. However, Intersil’s unique circuits allow the threshold to be reprogrammed to meet custom requirements or to fine-tune the threshold for applications requiring higher precision. ...
