I encountered some difficulties in the process of making a magnetically controlled lamp for a model, and I would like to ask for help from an expert. As shown in the figure, a control circuit is connected through a 6207 Hall switch and a flashing IC. Both ICs are sot23 packages. The Hall switch is triggered by a magnet to achieve the function of switching the LED long-on-flashing-fast flashing-off. The following is the schematic diagram of the Hall switch and the flashing IC. Finally, this is the circuit diagram drawn by my personal understanding. I am not sure if the circuit diagram is correct. Please help me. Thank you very much.

The circuit you drew at the end is wrong. The output of CC6207 is valid at high level, and TR needs a low level trigger, so the VOUT of 6207 is connected to a resistor (about 10K) and then connected to an NPN transistor (such as 9013). The transistor should be connected to the TR pin.

Your circuit is wrong. The 6207 should burn out as soon as the power is turned on.

The actual voltage is 3v. It shouldn't burn. The main reason is that I have no basic knowledge and am not good at circuit design. I am not sure if this circuit is correct.
