Overview
The MAX6428ORUR+T is a low-power single-level battery monitor featuring internal hysteresis, designed for monitoring single lithium-ion cells or multicell alkaline/NiCd/NiMH power supplies. It operates within a supply voltage range of 1V to 5.5V and consumes only 300nA of quiescent current. The device provides an active-low open-drain output that asserts when the supply voltage drops below the specified threshold, ensuring reliable system protection against deep discharge conditions in portable applications.
Feature Summary
- Internal hysteresis prevents output oscillation during slow voltage transitions
- Ultra-low quiescent current consumption extends battery life
- Active-low open-drain output compatible with standard logic levels
- Single-level monitoring for critical battery depletion detection
Applications
- Monitoring single lithium-ion (Li+) cell voltage levels
- Detecting low-battery conditions in multicell alkaline power supplies
- Power management in NiCd and NiMH battery systems
- Portable electronic devices requiring efficient battery supervision
Procurement Notes
Verify the specific suffix ORUR against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints and thermal requirements. Cross-reference the manufacturer's latest datasheet for any pinout revisions or handling instructions prior to integration into final designs.
Selection Notes
Select this component when a single-threshold battery monitor with minimal standby current is required. It is suitable for applications where detecting a single low-voltage state is sufficient, rather than dual-stage warnings. Consider the operating temperature range and package availability relative to the target product constraints.
Part Context
This part belongs to the MAX6427–MAX6438 family of low-power battery monitors. These devices are engineered to indicate three battery conditions: good, weak, or empty. The MAX6428 specifically offers a single low-battery output indicator, making it distinct from dual-output variants within the same series.
FAQ
Does the MAX6428ORUR+T include a manual reset function?
No, the MAX6428 does not feature a manual reset input; operation is automatic based on monitored voltage thresholds.
What is the typical quiescent current for this device?
The typical quiescent current is 300nA, supporting ultra-low power applications.
