Procurement Notes

Verify the specific suffix 'AND' against official Torex documentation to confirm pinout and electrical characteristics, as variations exist within the XC6805 series. Confirm current availability status directly with authorized distributors, as lifecycle changes may affect supply. Ensure compatibility with system power input ranges and thermal requirements before integration.

Selection Notes

Select this component for applications requiring integrated thermal protection via external thermistor monitoring. The USP-6EL package suits space-constrained designs. Verify that the required charge current and voltage settings align with the specific battery cell specifications. Consider the operating temperature range and supply voltage constraints during system design.
