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...
Simple current limiting circuit
When the current is below the specified threshold, the bias current supplied by resistor R1 causes transistor P3 to saturate and conduct. In this state, it is unable to regulate the current effectively. Conversely, when the current reaches or exceeds...
turn your power supply s power limit current limit
Through simple circuit modifications, designers can use peak current limiting to produce a constant current source.
A constant current source is an essential component in various electronic applications, providing a steady output current regardless of load fluctuations or variations in supply...
Lithium ion battery charging circuit diagram
A lithium-ion battery charging circuit is illustrated above. Initially, when charging begins, if the battery voltage is below 8.4V, the output of IC1 is inactive. As a result, Q2 remains off, and the LM317 operates in constant current mode. When...
