MAX6442KAEISD3-T

Overview

The MAX6442KAEISD3-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 an SOT-23-8 surface-mount package. The device supports an operating temperature range from -40°C to +85°C. Factory-trimmed thresholds are set for a reset voltage of 2.925 V, with high and low battery thresholds at 3.5 V and 3.0 V respectively.

Feature Summary

• Provides dual low-battery output options to signal battery status levels including OK, low, and dead conditions.
• Integrates an independent microprocessor supervisor that monitors VCC and provides an active-low reset output.
• Includes manual reset functionality allowing system reset via push-button without external components.
• Features factory-trimmed thresholds with hysteresis to eliminate output chattering in battery-operated systems.

Applications

• Single-cell lithium-ion battery monitoring
• Multicell alkaline battery management
• NiCd/NiMH battery applications
• Microprocessor system supervision

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details as specified in official documentation. Check lead time constraints and limited availability from distributors. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this variant for applications requiring specific factory-trimmed thresholds of 3.5 V and 3.0 V. Suitable for designs needing dual-level battery monitoring alongside microprocessor reset supervision. Consider the SOT-23-8 package for space-constrained surface-mount layouts. Verify compatibility with system voltage ranges between 1 V and 5.5 V.

Part Context
