ADCMP380-1ACBZ-RL7

Overview

The ADCMP380-1ACBZ-RL7 is an ultralow power voltage comparator with a 1 V internal reference, packaged in a 6-ball WLCSP. It operates on a supply voltage of 2 V to 5.5 V and consumes 92 nA typical current. The device features an open-drain output, an enable input, and input glitch immunity. It supports precision low voltage monitoring down to 0.5 V with ±1.6% accuracy at 1 V over the −40°C to +85°C temperature range.

Feature Summary

• Ultralow power consumption suitable for battery-operated equipment
• Precision internal reference level over full temperature range
• Enable input allows user to hold output low regardless of input state
• Input glitch immunity filters out fast transients

Applications

• Portable/battery-operated equipment
• Battery monitors
• Energy harvesting

Procurement Notes

Verify the specific suffix -RL7 indicates tape and reel packaging containing 3000 pieces. Confirm the -1 designation ensures the 1 V reference voltage variant rather than the 0.5 V option. Ensure the ACBZ package code matches the required 6-ball WLCSP footprint for your PCB layout.

Selection Notes

Select this part when system power efficiency is critical due to its 92 nA quiescent current. Choose the -1 suffix if the application requires a 1 V threshold; use -2 for 0.5 V monitoring. The open-drain output requires an external pull-up resistor. Consider the WLCSP size constraints as it is available only in a 6-ball package.

Part Context

This component belongs to the ADCMP380 family of ultralow power comparators. It shares the same package and general electrical characteristics with the ADCMP380-2ACBZ-RL7, differing only in the internal reference voltage setting. The evaluation board ADCMP380-EVALZ is available for testing this device family.

Replacement Considerations

ADCMP380-2ACBZ-RL7 (identical package and performance, but uses a 0.5 V internal reference instead of 1 V).
