Procurement Notes
Verify the exact suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer source is Analog Devices Inc. or Maxim Integrated. Ensure the part number matches the specific KARD7 variant for correct pinout and electrical characteristics. Check for RoHS compliance if required by your manufacturing standards.
Selection Notes
Select this component when both battery monitoring and system reset are required in a space-constrained design. The adjustable threshold allows flexibility for different battery discharge curves. Consider the SOT-23-8 package size for PCB layout constraints. Verify that the operating temperature range meets your environmental specifications.
Part Context
This part belongs to the MAX6846–MAX6849 family of ultra-low-power battery monitors. These devices combine battery monitoring with µP reset functionality. The family offers various package options and threshold settings. The MAX6848 specifically targets applications requiring multi-chemistry battery support.
Replacement Considerations
Check for MAX6846, MAX6847, or MAX6849 equivalents within the same family. Verify compatibility regarding package type and electrical parameters before substitution.
