NCP305LSQ15T1G

Supervisors Overview

The NCP305LSQ15T1G is a supervisory circuit voltage detector manufactured by onsemi, designed for monitoring single-input power supplies. It features a fixed threshold voltage of 1.5 V with an accuracy of 2%. The device operates within a supply voltage range of 800 mV to 10 V and draws a typical quiescent current of 1 uA. It provides an active low, open-drain reset output without manual reset or watchdog timer functionality. The component supports battery backup switching and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage detection with a fixed 1.5 V threshold and 2% accuracy for reliable system supervision.
• Features ultra-low power consumption with a typical quiescent current of 1 uA to extend battery life in portable applications.
• Includes battery backup switch capability to maintain monitoring during primary power loss scenarios.

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup switch functionality
• General-purpose power supply monitoring in consumer electronics

Supervisors Procurement Notes

Verify component authenticity through authorized channels as the part is listed as obsolete. Confirm RoHS compliance status via official manufacturer documentation before integration. Check for valid PCN records regarding material or assembly changes. Ensure compatibility with existing design constraints given the discontinued status.

Supervisors Selection Notes

Select this component for designs requiring a fixed 1.5 V detection threshold with high accuracy. Consider the SC-82AB package size for space-constrained PCB layouts. Evaluate the low quiescent current against system power budgets. Verify that the open-drain output interface matches the downstream logic requirements.
