The latest addition to our growing range of semiconductors and components at Tronixlabs Australia is the interesting Reset / Enable Controller - KA75330 3.3V Voltage Detector. Thus unassuming little item will monitor your 3.3V power channel - and when this drops below 3.3V, the KA's output pin will switch state from HIGH to LOW.
The KA75330 starts running at voltages as low as 0.8V so it'll be the first thing in your circuit that starts up. This little helper can really ease power start-up issues! Works best with microcontrollers and boards that have an Enable pin that is normally pulled high to enable function, and pulled to ground to disable.
