LP3470IM5X-2.63

Supervisors Overview

The LP3470IM5X-2.63 is a voltage supervisor circuit manufactured by Texas Instruments, designed for monitoring power supply rails in electronic systems. It operates within a maximum supply voltage of 5.5 V and features an active-low, open-drain output type. The device provides a reset threshold voltage of 2.63 V with a fixed reset delay time of 2 ms. It is housed in a SOT-23-5 surface-mount package and supports a single monitored input without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Provides active-low open-drain reset signaling for monitored voltage rails
• Features a fixed 2 ms reset delay to ensure stable power-up conditions
• Designed for compact surface-mount integration in space-constrained applications

Supervisors Applications

• Power-on reset generation for microcontrollers and digital logic
• Voltage supervision for battery-powered portable devices
• System reset management in embedded control circuits

Supervisors Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact electrical characteristics and packaging options. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary based on production lifecycle status.

Supervisors Selection Notes

Select this component when a precise 2.63 V threshold is required for system supervision. Ensure the application environment remains within the specified operating temperature range and that the open-drain output interface is compatible with the downstream logic levels.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on reset circuits from Texas Instruments. The series offers various threshold voltages to accommodate different supply rail requirements while maintaining a consistent low-power profile and small footprint suitable for modern portable electronics.

Supervisors Replacement Considerations

Direct substitutes include other LP3470 variants with adjusted threshold voltages, such as LP3470IM5-3.08/NOPB, provided the reset timing and output configuration remain compatible with the existing design constraints.
