Intelligent Battery-Charging Circuit Circuit
Intended for a NiCad application, this charging circuit can be used with a wide range of batteries. A low-battery detector is included, and the trip voltage is set via a 500 kΩ potentiometer. Select the resistor for the battery you...
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...
variable voltage and current power supply
An alternative method for utilizing operational amplifiers (op-amps) to regulate a power supply is illustrated below. The power transformer necessitates an additional winding to provide the op-amps with a bipolar voltage of +/- 8 volts. This negative voltage is also...
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...
Regulated 12 Volt Supply
This circuit utilizes a 13-volt zener diode (D2) for voltage regulation. Approximately 0.7 volts are dropped across the base-emitter junction of the transistors, resulting in a higher current output of 12.3 volts. The circuit is capable of supplying loads up...
A Power Management Interface Circuit For Telecom Hot Swap With Local Dc/dc Conve
New cellular phones have incorporated high-resolution cameras that require bright illumination of the surrounding area to achieve high-quality pictures. Traditional xenon-filled photo flashes cannot be used due to the limited space available in cellular phone cameras. Instead, design engineers utilize...
