You can use monolithic linear regulators at currents lower than 5 A for most applications. Most manufacturers of these devices integrate current-limiting and thermal shutdown to prevent damage during fault conditions. For currents greater than 5 A, ...
The ATtiny45/85 USB Phone Charge Guard controls and monitors the charging of phones and other devices (Figure 1). Voltage, current, power and energy are constantly measured via the INA219 and compared with the user limit values. It cuts off the ...
TinyCharger is an ATtiny25/45/85-based, single-cell Li-ion battery charger with selectable charging current limit (100 mA - 1000 mA) and an OLED display for monitoring. For Power Connecting device is equipped with a Micro-USB and a USB-C connector ...
Because the 8-pin ATtinys only have a few GPIO pins available, they are usually operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its 10% accuracy is often ...
Motivation This is a simple and fully automatic, 12 V uninterruptible power supply system for small/medium power appliances (Figure 1). This power supply specifically designs to drive routers and modems to provide uninterrupted internet and ...
Many switch-mode power supplies use “kick-start” circuits to initialize their offline operation. These circuits may be simple resistors, such as IRIS4015 , or more complicated arrangements built with bipolar transistors or MOSFETs. ...
Hackster.io With a code size of 1 KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps. There are a lot of so-called USB doctor modules which are used for monitoring currents flowing through a USB ...
Lukas Fässler soldernerd.com Some of you may have seen my arduino-based inductance meter in the article [1]. The arduino-based meter works well and made a great proof-of-concept. But for everyday use you’re probabely not looking for an ...
Although quartz crystals have served as temperature sensors, designers haven't taken advantage of the technology because few manufacturers offer the sensors as standard products (references 1 and 2 ). In contrast to conventional resistance- or ...
