Overview
The MAX6847KARD3-T is a low-power, adjustable battery monitor with hysteresis and an integrated microprocessor reset supervisor. It operates from a supply voltage of 1.6 V to 5.5 V and is housed in an SOT-23-8 package. The device supports an operating temperature range from -40°C to +85°C. It features user-adjustable thresholds for monitoring battery levels and provides active-low reset outputs. This component is designed for single-cell lithium-ion or multicell alkaline/NiCd/NiMH applications.
Feature Summary
- User-adjustable battery monitors with hysteresis
- Integrated microprocessor reset supervisor
- Low-power operation suitable for battery management
Applications
- Single-cell lithium-ion battery systems
- Multicell alkaline battery applications
- NiCd/NiMH battery monitoring circuits
Procurement Notes
Verify the exact suffix 'KARD3' against official Analog Devices documentation, as standard listings often use 'KASD3'. Confirm availability status directly with the manufacturer or authorized distributors due to potential discontinuation or limited stock issues associated with this specific part number variant.
Selection Notes
Select this component when adjustable low-battery detection thresholds are required alongside a dedicated microprocessor reset function. Ensure the application voltage range falls within 1.6 V to 5.5 V. Verify that the SOT-23-8 package fits the design constraints and that the operating temperature range meets environmental requirements.
Part Context
This part belongs to the MAX6846–MAX6849 family of ultra-low-power battery monitors. These devices integrate microprocessor supervisors with user-adjustable battery monitors. They signal when the battery is OK, low, or dead, providing independent reset outputs for system protection and control in portable electronic devices.
Replacement Considerations
Check for MAX6847KASD3+T or other variants within the MAX6846–MAX6849 family. Verify pinout compatibility and threshold adjustability before substitution.
