MAX6332UR23D3+T

Overview

The MAX6332UR23D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8V to 5.5V and features a fixed reset threshold of 2.3V. The device provides an active-high push-pull RESET output with a typical timeout period of 100ms. It is housed in a compact SOT-23-3 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides active-high reset signal via push-pull output
• Monitors single power supply input for undervoltage conditions
• Eliminates need for external components or adjustments

Applications

• Microprocessor system supervision
• Digital system power monitoring
• Battery-powered equipment reset control

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot details prior to integration. Ensure the selected variant matches the required active-high output specification, as other family members may offer different logic polarities.

Selection Notes

Select this part when an active-high reset signal is required for the host processor. Compare against MAX6333 variants if an active-low output is preferred instead. Verify that the 2.3V threshold aligns with the minimum operating voltage of the monitored circuit to ensure reliable assertion during brown-out events.

Part Context

This component belongs to the MAX6332/MAX6333/MAX6334 series of ultra-low-voltage, low-power µP reset circuits. These devices are designed to increase system reliability by asserting a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for a preset timeout period after VCC has risen above the reset threshold.

Replacement Considerations
