Frequently Asked Questions
How does the MCP73853-I/ML handle battery safety during USB charging at elevated temperatures?
The MCP73853-I/ML includes an integrated temperature sensing input that allows the charge controller to reduce or suspend the charge current when the battery or ambient temperature exceeds a safe threshold. This thermal regulation protects single-cell Li-Ion batteries from damage during charging, particularly when operating across the -40°C to +85°C industrial temperature range.
For a wearable device powered from a single Li-Ion cell, what package does the MCP73853-I/ML use and how does it affect PCB layout?
The MCP73853-I/ML is housed in a 16-pin VQFN package with an exposed thermal pad, providing a small footprint suitable for compact wearable PCBs. The exposed pad improves thermal conductivity to the board, enabling higher sustained charge currents without overheating in designs where board area is limited to a few square centimeters.
When comparing MCP73853-I/ML to a basic charge IC without temperature sensing, what risk does the temperature feature mitigate in USB applications?
USB ports may deliver current up to 500 mA (USB 2.0) or 900 mA (USB 3.0), and without temperature monitoring a basic charger can overheat the battery if the device is in an enclosed enclosure or charging in a high-temperature environment. The MCP73853-I/ML's thermal sensing circuit prevents Li-Ion cell damage by throttling the charge current when the 1-channel charger detects unsafe thermal conditions.
