Low voltage flasher
Applying voltage to the circuit triggers SCR1. With SCR1 on, the voltage on the anode of SCR2 rises until SCR2 triggers to commutate SCR1. The voltage on the gate of SCR1 will swing negative at this time, and only after...
How to extend the battery life of your microcontroller based design
Battery-powered devices, such as electric toothbrushes, shavers, cell phones, PDAs, MP3 players, and remote controls, are integral to daily life. Consequently, power management has become a critical consideration for embedded designers. Microcontrollers (MCUs) provide various methods for managing power requirements...
Low voltage detector
The values of R1, R2, and D1 are selected based on the voltage applied. Using a 12-volt battery, R1 is set to 10 kΩ, R2 to 5 kΩ, and D1 is a 5-volt zener diode or a string of forward-biased...
smart amp delay
This system is designed as a Windows service that detects various power events, including Suspend, Hibernate, Reboot, and Shutdown. It can send appropriate responses to a control circuit, specifically a Heartbeat or Kill signal. The trigger mechanism is also regulated...
Simple low voltage Oscillator circuit
The frequency remains stable as the voltage decreases. It is referred to as the "backwards JT" because it operates optimally with a bifilar coil and a single transistor. With a modification to the circuit, it is possible to deplete a...
under?-over voltage detector
In Fig. 1 A precision DC undervoltage relay switch. The op-amp is wired as a voltage comparator, with a reference voltage applied to pin 2 and the test voltage applied to pin 3: the relay turns on when the pin...
Power Path Management Battery Charger
Powering the system is required by many applications while charging the battery simultaneously. Interaction between the system and charger may result in a...
Power management in electronic systems is critical, particularly in applications that necessitate simultaneous operation and battery charging. This...
Voltage detector relay
While the battery is charging, its voltage is measured at V. If the measured voltage is lower than the minimum threshold, the relay will be activated, connecting the charger circuit. When the battery voltage exceeds the maximum set point, the...
Computer Off Switch
How often does it happen that a user shuts down Windows and then forgets to turn off the computer? This circuit automates that process. After Windows is shut down, a click occurs a second later, disconnecting the PC from the...
