MAX6333UR23D2

Overview

The MAX6333UR23D2+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.3 V. The device provides an active low, push-pull output with a reset delay time of 100 ms. It consumes a typical operating supply current of 3.3 uA and includes no manual reset, watchdog timer, or battery backup switch. The component supports surface mount installation in an SOT-23-3 package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides simple power-on reset functionality with a fixed 100 ms timeout period
• Features ultra-low quiescent current consumption for battery-powered applications
• Delivers a robust push-pull active low output signal

Applications

• Microprocessor system supervision
• Portable electronic devices requiring low power monitoring
• Battery-operated equipment protection

Procurement Notes

Verify the specific suffix D2 against official datasheets to confirm the exact 2.3 V threshold specification. Confirm RoHS compliance status and check for obsolescence notices from Analog Devices. Ensure the SOT-23-3 footprint matches your PCB design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 100 ms reset delay and 2.3 V threshold are required. Compare against other MAX6333 variants if different timeout periods or voltage thresholds are needed. Verify that the push-pull output type suits the downstream logic interface without requiring external pull-up resistors.

Part Context

This part belongs to the MAX6333 series of microprocessor supervisors designed for low-power applications. These circuits monitor voltage levels and generate reset signals to ensure system stability during power transitions. The series offers various threshold voltages and timeout options packaged in small form factors suitable for space-constrained designs.

Replacement Considerations

Check for direct substitutes within the MAX6333 family offering identical 2.3 V thresholds and 100 ms delays. Verify pin compatibility and electrical specifications before substituting with other voltage supervisor ICs.
