C1 has a minimum value of 1000 F , this enables an open circuit or missing component to be detected. There is no maximum limit other than extended charge time. 2. MTH100 charges the Hold-up capacitor C1 to 45 V max when charge voltage programming (CVP) pin is connected or 35 V when not connected. 3. Input DC fail programming (DCFP) sets the power fail voltage threshold using resistor R1. See formula for the value required. 4. Input DC fail detect (DCFD) is an open collector circuit which changes state when the input voltage fails below the set threshold. 5. Charge/discharge detect (CDD) is an open collector circuit which goes low when C1 is charged to 90% of Vcap or high when C1 discharges down to 30% of Vcap. 6.
