Overview
The MAX6439UTEHRD3+ 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 is housed in a SOT-23-6 package. The device supports surface-mount installation and functions across a temperature range of -40°C to +85°C. It provides active-low reset outputs and low-battery alerts without requiring external components.
Feature Summary
- Integrates ultra-low-power battery monitoring with independent microprocessor supervision capabilities
- Offers factory-trimmed low-battery threshold combinations for various battery chemistries
- Provides manual reset functionality via push-button input for system control
Applications
- Single-cell lithium-ion battery monitoring systems
- Multicell alkaline, NiCd, or NiMH battery management applications
- Microprocessor reset supervision in portable electronic devices
Procurement Notes
Verify the specific suffix 'EHR' against official Maxim Integrated documentation to confirm the exact low-battery threshold configuration. Ensure compatibility with the target operating voltage range and thermal requirements. Confirm RoHS compliance status through current manufacturer datasheets prior to procurement.
Selection Notes
Select this component when designing systems requiring simultaneous battery health monitoring and processor reset supervision. The integrated hysteresis prevents output oscillation during voltage transitions. Consider the available threshold options to match specific battery discharge curves for optimal system protection and operational efficiency.
Part Context
This part belongs to the MAX6439–MAX6442 family of battery monitors. These devices are designed to replace discrete solutions by combining battery monitoring and reset generation into a single compact package. The family offers multiple threshold configurations to suit different battery types and system requirements.
Replacement Considerations
Cross-reference with other MAX6439 variants (e.g., MAX6439UTLTYD3+) to find matching threshold specifications. Verify pinout compatibility and electrical characteristics before substitution.
