LM3909N product description

         1. Can be used for low voltage (1.5V to 3V) and low current (about 1mA) to work, suitable for portable equipment and energy-saving applications.

         2. The flash frequency and flash time can be automatically adjusted according to the voltage of the battery and the characteristics of the LED, without external components.

         3. It can drive many types of LEDs, including red, green, yellow, white, etc., just change the polarity of the battery.

         4. With high stability and reliability, it can work normally in the temperature range of -40°C to +85°C.

         5. It has the characteristics of low power consumption and long life, which can prolong the battery life.
