The grounding pin for 12 V system. n Terminal Equivalent Circuits (continued) GND19 n Usage Notes 1. The sequence of power supply turning on and off 1) Turning on sequence: First time: Pin 2 (12 V power supply) Second time: Pin 1 (12 V power supply) 2) Turning off sequence: First time: Pin 1 (12 V power supply) Second time: Pin 2 (12 V power supply) If pin 2 voltage is decreased to 4.5 V or less under the established state of pin 1, an abnormal current of 20 mA to 50 mA flows to pin 1, so that there is a possibility of breakdown of the IC. The above setting sequence should be observed. The normal operation of the IC has been confirmed after tuning on and off SW 100 times at the interval of 1 second with the following testing circuit. Therefore, there will be no problem even if a current under 50 mA is allowed to flow to pin 1 for only about 1 second at turning on and turning off the set power supply. However, we do not give you guarantee by our shipping test.

n Usage Notes (continued) 4. The change in the output voltage by VCC2 voltage change. If pin 2 voltage becomes a voltage of 8.3 V or less by making R2 value larger, the upper limit of TILT output voltage is restricted and becomes as shown in figure 1. Care must be taken at using VCC2 at a voltage of 8.3 V or less. V CC1 V CC
