The order of power supply turning on and off 1) Turning on sequence 1st time pin 2, pin 3 (12 V power supply) 2nd time pin 1 (12 V power supply) 2) Turning off sequence 1st time pin 1 (12 V power supply) 2nd time pin 2, pin 3 (12 V power supply) In the state that the pin 1 has been established, if pin 2 or pin 3 is decreased to under 5 V, an abnormal current of 50 mA to 300 mA flows to pin 1, so that there is a possibility of breakdown of the IC. The above setting sequence should be observed. It is confirmed that the IC operates normally after turning on and off SW 100 times at the interval of 1 second using the following circuit. Therefore, there will be no problem even if a current of 100 mA or less is allowed to flow to pin 1 for only about 50 ms at turning on and turning off the set power supply. However, we do not give guarantee by shipping test. 100 mA 12 GND2 GND1 11 10 9 8 7 6 GND3 5 4 VCC3 3 VCC2 2 VCC1 1 2.

The change in output voltage by the VCC2 and VCC3 voltage change 60 Ω V5 If pin 3 (VCC3) becomes a voltage of 8 V or less by making resistance value of R3 larger, the upper limit of output voltage for pin 7 and pin 8 is restricted and then the output becomes as shown in figure 1. Similarly, if pin 2 (VCC2) voltage becomes 8 V or less by making resistance value R2 larger, the output voltage of pin 10 and pin 11 becomes as shown in figure 2. A care must be taken in case of using VCC2 and VCC3 at a voltage of 8 V or less. 7 AN5452 ICs for TV ■ Usage Notes (continued) 3.
