All rights reserved. www.rohm.com TSZ22111・15・001 ● Description of application operations in blocks (1) Start circuit (VH pin: 8 pin) This IC has a built-in start circuit (withstands 650 V). This enables both low standby mode power and high-speed startup. This start circuit operates only at startup. The current flow when operating is shown in Figure 5. After startup, the power consumed is only for the idling current I START3 (typ = 10 uA). ex) When Vac = 100 V, power consumption is from start circuit only PVH = 100 V* √2*10 uA = 1.41 mW ex) When Vac = 240 V, power consumption is from start circuit only PVH = 240 V* √2*10 uA = 3.38 mW Startup time is determined based on the inflow current for the VH pin and the capacitance for the VCC pin. Startup time reference values are shown in Figure 6. For example, when Cvcc = 10 uF, startup takes about 0.07 seconds. When the VCC pin has been shorted by GND, the ISTART1 current in Figure 5 flows. When the VH pin has been shorted by GND, a large current flows to GND from the VH line. To prevent this, insert resistor RVH (5 kΩ ~ 60 kΩ) to limit the current between the VH line and the VH pin of the IC. When the VH pin is shorted, the power of VH 2/R VH is applied to the resistor. Therefore, select a resistor size that is able to tolerate this amount of power. If one resistor is not enough for the allowable power, connect two or more resistors in series. Figure 4.
