MAX6436UT-T

Overview

The MAX6436UT+T is a low-power battery monitor designed for single or dual-cell alkaline, NiCd, and NiMH batteries. It operates within a supply voltage range of up to 5.5V and features an operating temperature range of -40°C to +85°C. The device is housed in a compact SOT-23-6 surface-mount package. It provides internal hysteresis to prevent output chatter during threshold transitions and includes an integrated microprocessor reset supervisor with manual reset functionality.

Feature Summary

• Provides single or dual-level battery status monitoring for multi-chemistry cells
• Integrates a microprocessor supervisor with active-low reset output
• Features internal hysteresis to ensure stable switching without external components

Applications

• Portable electronic devices requiring battery level indication
• Systems utilizing alkaline, NiCd, or NiMH battery packs
• Microprocessor-based circuits needing power supervision and manual reset

Procurement Notes

Verify the exact suffix (e.g., +T) against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure the source document explicitly identifies the component as the MAX6436 series. Cross-reference the package type SOT-23-6 and voltage limits with official Analog Devices documentation before integration.

Selection Notes

Select this component when designing systems that require dedicated battery health monitoring alongside processor reset supervision. It is suitable for applications where minimizing external component count is critical. Verify that the specific battery chemistry (alkaline, NiCd, or NiMH) matches the device's configured thresholds. Confirm that the SOT-23-6 footprint aligns with the PCB layout constraints.

Part Context

The MAX6436 belongs to a family of ultra-low-power battery monitors from Maxim Integrated, now part of Analog Devices. This series typically includes variants like the MAX6439 through MAX6442, offering different threshold configurations. These devices are engineered to replace discrete comparator solutions, providing a compact alternative for portable equipment power management.

Replacement Considerations

Consult the official Analog Devices cross-reference guide for verified substitutes. Ensure any replacement maintains the SOT-23-6 package and compatible voltage thresholds. Do not assume functional equivalence between different suffixes without explicit datasheet confirmation.
