MAX6328XR22+T

Overview

The MAX6328XR22+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed threshold voltage of 2.20 V. The device provides an active-low, open-drain reset output with a typical reset delay time of 200 ms. It is designed for ultra-low-power applications, drawing only 500 nA of quiescent current. Accuracy is specified at 1.5%, ensuring reliable monitoring. The component is housed in a compact SC-70-3 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact SC-70-3 surface-mount packaging for space-constrained designs
• Fixed threshold voltage ensures precise power supply monitoring

Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation and sensors
• Embedded systems needing reliable power-on reset signals

Procurement Notes

Verify the specific suffix 'R22' confirms the 2.20 V threshold voltage against official datasheets. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure compatibility with the required SC-70-3 footprint and verify RoHS compliance status for your region's regulatory requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 2.20 V threshold is required for system supervision. Consider the 500 nA quiescent current if battery life is critical. Verify that the SC-70-3 package dimensions fit the PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the MAX6328X series of ultra-low-power, microprocessor reset circuits. The series offers various fixed threshold voltages to accommodate different supply rails. The MAX6328XR22+T specifically targets applications requiring a 2.20 V monitoring level. It shares common family features such as low power consumption and compact packaging with other variants in the lineup.

Replacement Considerations

Cross-reference with other MAX6328 variants having the same threshold or compatible packages. Check for pin-compatible alternatives from other manufacturers offering similar threshold voltages and low-power specifications. Verify electrical parameters match exactly before substitution.
