This is a Shutdown Schemes of MAX1044/ICL7660. Additional capacitive loading on the OSC pin of the device will reduce the oscillator frequency, so we should be aware when using the circuit. Compared with other circuits, the first circuit has the least loading on the OSC pin. Using a high or low logic level this circuit has the added advantage of […]

The circuit diagram below show us a typical circuit for welding equipment. Accurate control of the maximum turn-on delay can be reached using potentiometer P2. C1 can be discharged using DB1 diode bridge and R6-R7 resistors at each line zero voltage. This will maintain the same turn-on delay and resets the voltage charge at each new half line cycle. Power […]
