Adafruit Reset / Enable Controller - KA75330 3.3V Voltage Detector

A voltage detector ensures your microcontroller remains operational without suffering from low voltage issues. Perfect for setups like a Feather Huzzah running on a lipoly battery which can dip below 3.3V, leading to performance problems such as lockups or corrupted data.

This device monitors the input pin voltage, pulling the output pin low when levels drop below 3.3V, effectively preventing under-voltage operation. Connect it to the Enable pin to safeguard against insufficient voltage conditions that could prematurely activate your microcontroller.

The KA75330 activates at 0.8V, ensuring it's the initial component to power up in your circuit, alleviating start-up stress. It pairs best with boards featuring an Enable pin setup, facilitating safe operation. Proper functionality requires 2.2uF electrolytic capacitors on input and output for stabilization.
