LP3470IM5X-2.93

Supervisors Overview

The LP3470IM5X-2.93 is a voltage supervisory circuit manufactured by Texas Instruments, formerly National Semiconductor. It monitors a single input with a threshold voltage of 2.93 V and features an active-low, open-drain output. The device operates within a supply voltage range up to 5.5 V and includes a reset delay time of 2 ms. It is housed in a SOT-23-5 package and supports surface-mount installation across a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single-input systems
• Features active-low open-drain output for flexible interfacing
• Includes a fixed 2 ms reset delay to ensure stable power-up sequences

Supervisors Applications

• Portable equipment power management
• Battery-powered system monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the manufacturer origin as Texas Instruments acquired National Semiconductor. Confirm the specific suffix indicates the 2.93 V threshold variant. Check RoHS compliance status and current production lifecycle status before procurement.

Supervisors Selection Notes

Select this component when a 2.93 V threshold is required for single-channel supervision. Ensure the SOT-23-5 package fits the design constraints. Verify that the open-drain output type matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the LP3470 family of tiny power-on reset circuits. The IM5X suffix denotes the SOT-23-5 surface-mount package configuration. The 2.93 designation specifies the exact voltage threshold for this specific variant within the broader series.

Supervisors Replacement Considerations

Direct substitutes include other LP3470 variants with different thresholds or the LP3470A series. Verify pin compatibility and threshold voltage accuracy when replacing.
