USB battery chargers are increasingly popular. Today we present you a smart little one we call VOLT.
We wanted to make something that you can easily integrate in your devices and have fully functional battery charger as well as battery powering solution.
It features power management circuitry which can charge the battery over USB connector. Using provided screw terminals (VSYS and GND) VOLT can also be used to power your target device from battery (Vbat) or USB (5V). When USB is connected battery is charging and VSYS outputs 5V. Power LED is active when either USB or battery is connected, while Charge LED lights up only when battery is charging. Additional screw terminals with STAT and SENSE lines enable battery charge monitoring.
