VOLT (USB Li-Po Charger) The VOLT is a smart USB Li-Polymer battery charger. It features power management circuitry including the MCP73832 charge-controller, which can charge the battery from USB power. Using the provided screw terminals (VSYS and GND) the VOLT can also be used to power your target device from battery (Vbat) or USB (5V). When USB is connected the battery is charging and VSYS outputs 5V. The Power LED is active when either USB or the battery is connected, while the Charge LED lights up only when the battery is charging. Additional screw terminals with STAT and SENSE lines enable battery charge monitoring. R340  Qty: Add to Basket Price ex. VAT. Est. Weight: 10g. Stock: Lead-time applicable [i].

Charger click Charger click carries both a battery charger controller and a battery charge monitor, along with a battery connector. The smaller chip is MCP73831, a miniature single-cell Li-Ion and Li-Polymer charge management controller with a programmable charge current from 15 to 250 mA. The larger IC is DS2438, a smart battery monitor which integrates a temperature sensor, a timer, an ADC to measure the battery voltage and current, and a current accumulator that monitors the total amount of current going into and out of the battery. Charger click communicates with the target MCU through a 1-Wire interface. Charger click is designed to use a 5V power supply. R515  Qty: Add to Basket Price ex. VAT. Est. Weight: 20g.
