Switching between battery and external power source : …
Hey there! Trying to design a circuit to automatically switch to use external 5V power source when available, otherwise use its non-rechargeable battery (could be 6V when new to 3.3V when device no longer operable). I am thinking to connect the battery to the ...
Switching between two power sources
I am designing a circuit, which can use either 5V from USB, or some higher voltage (7-12V) from a battery. If both power sources are connected at the same time, I want some kind of electrical switch, that would disconnect the battery and power the circuit just from ...
Power MUX – safely and easily controlling the switching between different power …
This requires a solution for seamlessly transitioning between the internal battery and the external power sources. But, connecting multiple power supplies to a single input without any protection can result in loss of power, power failure and short circuits. For that
Automatic Power Supply Switching For Battery …
In this switching circuit, the source of power supply to a load circuit is changed between the battery and DC power. The main components that play important role in the functioning of this circuit are …
FT930 RTC External Power Switch Circuit
The FT930/FT931 device contains an internal Real Time Clock (RTC) circuit with an external power pin (VDDBAT, PIN 63 of FT930 / PIN 54 of FT931). It is connected to a …
Switching and protecting electronics in battery-powered systems
Figure 1 A possible battery and load protection discrete circuit For a 3.7V Li-Ion cell, this level is around 2.5V. An undervoltage lockout (UVLO) circuit is needed to disconnect the battery from the load. This may be implemented with a comparator, reference voltage ...

Switching Between Battery and External Power Sources
Portable equipment that can operate from a battery pack or an external power source (such as a wall-adapter or external supply) needs to be able to smoothly switch between the two power sources. This application note describes a circuit (Figure 1) that switches power sources with good efficiency and without switching noise.
Arduino Transistor (NPN/PNP Switch) Tutorial
PNP Transistor Switching Circuit Diagram Here is a generic circuit diagram for an Arduino PNP Transistor switch that can be used to control any load (like DC Motor, LED, Heater, etc). The load supply is equal to the Arduino power supply (both are +5v) and they share a common ground as you can see in the diagram below.
Switch between 5V power supply and 6.6 battery
Let''s consider different situations. For the circuit below, I considered four different situations. 1)External 5v is connected and battery is at the maximum voltage(6.6v) Vgs=-1.6v : In this situation, for proper circuit operation, Q1 must be off. 2)External 5v is connected and battery is at the minimum voltage(4v) Vgs=1 : In this situation, for proper …
