MAX6336US20D3

Overview

The MAX6336US20D3 is a fixed-threshold microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8V to 3.3V and features a fixed reset threshold voltage of 2.0V. The device utilizes a push-pull, active-low output configuration and is housed in a 4-pin SOT-143 package. It supports an operating temperature range from -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Fixed 2.0V reset threshold for precise power monitoring
• Push-pull active-low output driver
• Ultra-low-voltage operation suitable for 1.8V–3.3V systems

Applications

• 1.8V digital system supervision
• 3.3V digital system supervision
• Microprocessor reset circuits

Procurement Notes

Verify the specific suffix (e.g., +T) against the manufacturer's current datasheet to confirm tape-and-reel packaging and lead-free status. Ensure the part number matches the exact threshold voltage requirement of 2.0V. Cross-reference the package type as SOT-143 to avoid confusion with other pinout variants.

Selection Notes

Select this component when a fixed 2.0V threshold is required for 1.8V to 3.3V logic families. The push-pull output eliminates the need for external pull-up resistors. Verify that the fixed threshold meets the system's brown-out detection requirements without needing adjustable potentiometers.

Part Context

This part belongs to the MAX6336 family of ultra-low-voltage, low-power microprocessor reset circuits. These devices are designed to monitor supply voltages and generate reset signals for digital systems. The US20 variant specifically denotes the 2.0V threshold setting within the series.

Replacement Considerations

Compatible substitutes include MAX6336US16D3 (1.6V threshold) or MAX6336US25D3 (2.5V threshold) if the threshold voltage can be adjusted. Ensure the replacement maintains the SOT-143-4 package and push-pull output characteristics.
