MAX6336US25D3+T

Overview

The MAX6336US25D3+T is a single-channel voltage supervisor IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a fixed threshold voltage of 2.5V and provides an active-low reset signal with push-pull/totem pole output capability. The device is designed for simple reset and power-on reset applications, monitoring one input voltage. It operates within a temperature range of -40°C to +125°C and is housed in a SOT-143-4 surface-mount package.

Feature Summary

• Provides active-low reset signal generation based on monitored supply voltage
• Features push-pull or totem pole output stage for robust drive capability
• Supports manual reset functionality via dedicated input pin
• Designed for low-power operation suitable for battery-backed systems

Applications

• Microprocessor reset circuits requiring precise voltage supervision
• Power-on reset generation for digital logic systems
• Battery backup switching supervision in portable electronics
• Manual reset input integration for system control interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status in some channels. Confirm RoHS compliance and REACH registration status prior to procurement. Check for alternative lead-free variants if environmental regulations require specific certifications. Ensure packaging matches design requirements for surface mount assembly processes.

Selection Notes

Select this component when a fixed 2.5V threshold is required for single-supervision applications. Consider the SOT-143-4 package size for space-constrained designs. Evaluate the push-pull output against open-drain alternatives if drive strength is critical. Verify operating temperature range compatibility with the intended environment before final selection.

Part Context

Part of the MAX6335-MAX6337 series of supervisory circuits offering various threshold voltages and timeout periods. The US25 suffix indicates the 2.5V threshold variant. The D3 suffix typically denotes the SOT-143-4 package configuration. This series is widely used in embedded systems requiring reliable power management supervision.

Replacement Considerations

MAX6336US25D3-T is the non-RoHS equivalent version. MAX6336US22D2+T offers a 2.2V threshold alternative. Cross-reference datasheets for pinout and electrical parameter compatibility before substitution.
