LP3470M5X-2.93/NOPB

Supervisors Overview

The LP3470M5X-2.93/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring power supply integrity in embedded systems. It operates within a maximum supply voltage of 5.5 V and features a precise reset threshold of 2.93 V with 1% accuracy. The device provides an active-low, open-drain output and includes a fixed reset delay time of 2 ms. It functions without manual reset or watchdog timer capabilities. The component supports surface-mount installation in a SOT-23-5 package and maintains low operating supply current of 16 uA across a temperature range of -20°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with 1% threshold accuracy
• Features active-low open-drain output for system reset signaling
• Operates with ultra-low quiescent current consumption
• Includes fixed 2 ms reset delay for stable power-up sequencing

Supervisors Applications

• Portable electronic devices requiring low-power voltage monitoring
• Battery-operated systems needing reliable power-fail detection
• Embedded controllers requiring stable power-on reset sequences

Supervisors Procurement Notes

Verify the specific suffix '2.93' confirms the 2.93 V threshold voltage variant. Confirm the 'M5X' designation corresponds to the SOT-23-5 package type. Ensure the 'NOPB' suffix indicates lead-free and RoHS compliance status as per manufacturer specifications. Cross-reference the full part number against official Texas Instruments documentation to confirm availability and lifecycle status before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.93 V reset threshold is required for single-input voltage monitoring. Choose this part if the application demands minimal standby current and does not require manual reset or watchdog functionality. Ensure the operating environment stays within the specified -20°C to +85°C temperature range. Verify that the SOT-23-5 package fits the available PCB footprint constraints.
