LP3470M5-2.63

Supervisors Overview

The LP3470M5-2.63 is a tiny power-on reset circuit manufactured by Texas Instruments, designed for monitoring supply voltages in portable and battery-powered applications. It features an active-low open-drain output that asserts when the supply voltage drops below a precise threshold of 2.63 V with 1% accuracy. The device operates within a supply voltage range up to 5.5 V and includes a programmable reset delay time of 2 ms, adjustable via an external capacitor. It functions reliably across an extended temperature range from -20°C to +85°C and consumes low quiescent current, making it suitable for space-constrained designs requiring reliable system supervision.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 1% reset threshold accuracy
• Features an active-low open-drain output for direct interface with digital logic
• Includes a programmable reset delay controlled by an external capacitor
• Operates with low quiescent current to extend battery life in portable devices

Supervisors Applications

• Portable consumer electronics requiring reliable power management
• Battery-operated systems needing voltage supervision
• Embedded controllers requiring stable power-on reset signals
• Space-constrained mobile devices utilizing SOT-23-5 packaging

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with your design requirements. Confirm the operating temperature range and reset threshold voltage match your application needs. Check for end-of-life status or recommended new designations if sourcing for long-term production. Ensure the supplier provides authentic components with proper traceability documentation.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for system supervision. Consider the 2 ms programmable delay feature for managing power-up sequences. Evaluate the SOT-23-5 package size for PCB space constraints. Compare quiescent current specifications against other supervisors in the LP3470 family to optimize power efficiency for battery-dependent applications.

Supervisors Part Context

This part belongs to the LP3470 series of tiny power-on reset circuits from Texas Instruments. The series offers various fixed threshold voltages to accommodate different supply rails. The M5 suffix indicates the SOT-23-5 package option. These devices are designed for low-power applications where precise voltage monitoring and small form factors are critical for system reliability and portability.

Supervisors Replacement Considerations

Check for LP3470M5-2.63/NOPB as a potential equivalent designation. Verify pinout compatibility with other LP3470 variants before substitution. Ensure the replacement part meets the same electrical specifications and package dimensions.
