The order of power supply turning on and off 1) Turning on sequence 2) Turning off sequence 1st time pin 2, pin 3 (12 V power supply) 2nd time pin 1 (12 V power supply) 1st time pin 1 (12 V power supply) 2nd time pin 2, pin 3 (12 V power supply) AN5452 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. 2. Circuit for checking abnormal current 10 11 11 GND1 12 VCC1 1 VCC2 2 VCC3 3 GND3 100 mA SW 55 Ω B A A VCC1 12 V B 1s 1s A B 3.

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. GND1 12 4 5 6 7 8 9 7 AN5452 s Usage Notes (continued) 3.
