Battery Chargers Procurement Notes

Verify the product status as obsolete before procurement planning. Confirm package compatibility with the 10-VFDFN exposed pad footprint. Ensure design-in accounts for the limited operating temperature range of -20°C to 70°C. Check for available replacement components from Renesas due to end-of-life status.

Battery Chargers Selection Notes

Select this component for applications requiring integrated monitoring of cell voltage and temperature. Consider the 6.5V maximum supply limit when designing input circuits. Evaluate the 1.5A current limit against load requirements. Verify thermal performance within the specified ambient temperature range during operation.
