Hence, pnp transistor Q 3 provides this high-side drive. Bipolar-junction transistors Q 1 and Q 3 meet cost considerations, but you could also use MOSFETs for slightly better performance. The ...

The LT Spice simulation output below shows the circuit breaker tripping. You can see the current ramping up and the output voltage dropping to zero when the current reaches about 750mA. I have used ...

2. The detailed circuit uses five standard transistors plus passive components to implement the one-pin battery-monitor solution. When the microcontroller decides it needs to know the battery ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.
