Overview
The MAX6442KANRRD7+T is a low-power, single/dual-level battery monitor with hysteresis and an integrated microprocessor reset supervisor. It operates within a supply voltage range of 1 V to 5.5 V and features factory-trimmed low-battery thresholds for lithium-ion or multicell alkaline/NiCd/NiMH applications. The device provides active-low outputs indicating battery status (OK, low, dead) and includes a manual reset function via push-button. It is housed in an SOT-23-8 package and supports surface-mount installation across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides dual low-battery output options to signal battery health states including OK, low, and dead conditions.
- Integrates an independent microprocessor supervisor that monitors VCC and generates an active-low reset output.
- Supports manual system reset functionality through an external push-button connection.
- Requires no external components for operation due to internal trimming and integrated circuit design.
Applications
- Single-cell lithium-ion battery monitoring systems
- Multicell alkaline battery management applications
- NiCd and NiMH battery pack supervision
- Microprocessor reset circuits in portable devices
Procurement Notes
Verify the specific suffix KANRRD7+ against official Analog Devices documentation to confirm exact threshold combinations and package variants. Cross-reference datasheet revision history for any functional updates. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component when requiring precise, factory-trimmed battery voltage thresholds without external calibration. Consider the integrated µP reset feature for simplified system architecture. Evaluate the SOT-23-8 package constraints for space-limited designs. Confirm that the specified operating temperature range meets environmental demands.
Part Context
This part belongs to the MAX6439–MAX6442 family of ultra-low-power battery monitors manufactured by Maxim Integrated, now part of Analog Devices. These devices are designed for power management ICs (PMIC) applications, specifically focusing on battery supervision and microprocessor reset generation in portable electronics.
Replacement Considerations
Direct substitutes within the same family include MAX6441KACJSD7+T and MAX6442KAEJTD7+T. Verify pinout compatibility and threshold specifications before substitution. Consult official cross-reference guides for alternative packages or updated revisions.
