- Low-power battery management circuits
Procurement Notes
Verify the component origin and authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status, as sources indicate non-compliance for this specific part number. Ensure the package type matches the required SOT-23-4 footprint. Check operating temperature specifications against environmental requirements. Validate datasheet revisions for any functional updates.
Selection Notes
Select this component when dual-level battery detection with hysteresis is required for multi-chemistry batteries. Consider the 1.2V to 5.5V operating voltage range and -40°C to +85°C temperature limits. The SOT-23-4 package suits space-constrained designs. Verify power consumption needs align with its low-power design characteristics.
Part Context
This part belongs to the Maxim Integrated (now Analog Devices Inc.) battery management portfolio. It serves as a specialized monitor for detecting battery states in portable devices. The TO-253/TO-253AA references in some listings appear inconsistent with the standard SOT-23-4 package; the SOT-23-4 designation is the primary verified package type for this model.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer cross-reference guides for potential alternatives.
