MAX6432ORUS-T

Overview

The MAX6432ORUS-T is a dual-level battery monitor with an integrated microprocessor supervisor, manufactured by Maxim Integrated (Analog Devices). It operates within a voltage range of 1.6V to 5.5V and features a fixed low-battery threshold of 2.1V and a high threshold of 2.5V. The device provides active-low outputs for both battery status and reset functions. It utilizes a 6-pin USON package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-output architecture providing independent indicators for battery health and microprocessor supervision
• Integrated hysteresis prevents output oscillation during voltage transitions near threshold levels
• Manual reset input allows system initialization via push-button without external components
• Factory-trimmed thresholds ensure accurate detection of low-battery conditions

Applications

• Monitoring single lithium-ion cells in portable electronics
• Supervising multi-cell alkaline or NiMH/NiCd power supplies
• Microprocessor reset generation in embedded systems
• Low-power mode signaling in battery-operated devices

Procurement Notes

Verify the specific suffix ORUS against the manufacturer's official datasheet to confirm package type and thermal characteristics. Ensure the order matches the exact part number including the trailing T for tape-and-reel configuration. Cross-reference the revision level to guarantee compatibility with current design specifications.

Selection Notes

Select this component when dual monitoring capabilities are required for both battery integrity and processor stability. It is suitable for designs needing fixed thresholds without external resistor networks. Consider the USON package size for space-constrained layouts. Verify that the fixed voltage thresholds align with the specific battery chemistry being monitored.

Part Context

This device belongs to the MAX6439–MAX6442 family of ultra-low-power battery monitors. These parts share common architectural features such as integrated supervisors and manual reset inputs. The MAX6432 variant specifically offers dual low-battery outputs, distinguishing it from single-output counterparts in the series.

Replacement Considerations

Check for MAX6432ORUS+T for lead-free compliance if RoHS requirements differ. Other family members like MAX6431 or MAX6437 may offer similar functionality but with different pinouts or threshold configurations.
