Here is a Dual power source for the Home Security system which has to be switched on continuously. It is a power saving circuit that uses a Solar panel for providing power during day time and a ...

When either power supply is at 0V potential because that side of the circuit has been powered-down, all eight bus-related terminals are set to a high-impedance state, and any voltage up to 3.6V can be ...

Learn how to select a power-supply configuration based on PPG system requirements. Review the implementation of switched-mode power-supply reference circuits for both discrete (Part 1) and ...

These power-supply circuits will work with MAX86141-based PPG devices as well. In Part 2, we present pre-validated integrated power-supply circuits for use with both MAX86171- and MAX86141-based ...
