Home|FAQ Search| Please provide the value for ICT for cases where the applied voltage to the power supply is greater than the detection voltage (BD52xx/BD53xx series. (In the specifications the ICT value is listed for VDD=0.95V and 1.5V)
According to the specifications listed in the data sheet, since ICT is the discharge current from the capacitor connected to the CT terminal, VDD will become lower than the detection voltage. For example, in the BD5223 when VDD falls below 2.3V, for power supply voltages greater than 2.3V the capacitor at the CT terminal wil become charged. The discharge current ICT for power supplies at 3.0V will be out of specifications.
