LP3470A293DBVR

Supervisors Overview

The LP3470A293DBVR is an ultra-low-power active-low reset integrated circuit manufactured by Texas Instruments. It monitors a single input voltage with a fixed threshold of 2.93 V and provides a reset signal when the supply drops below this level. The device features a programmable delay time set by an external capacitor, ensuring stable power-up sequencing. It operates within a supply voltage range up to 10 V and maintains accuracy within 1%. The component is housed in a compact SOT-23-5 package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low quiescent current consumption for battery-powered applications
• Programmable reset delay using an external capacitor
• High precision voltage monitoring with 1% threshold accuracy
• Active-low open-drain output compatible with various logic families

Supervisors Applications

• Portable electronic devices requiring low standby power
• Microcontroller system power supervision
• Battery-operated equipment voltage monitoring
• Industrial control systems operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific threshold voltage suffix matches the design requirement of 2.93 V. Confirm the DBVR package variant availability through authorized distributors. Check for RoHS compliance status as indicated in official documentation. Ensure the ordering part number aligns with the required tape and reel or cut tape packaging options specified by the manufacturer.

Supervisors Selection Notes

Select this component when a precise 2.93 V monitoring point is required with minimal static current draw. The programmable delay feature allows customization of reset timing via external capacitance. Consider the SOT-23-5 footprint for space-constrained PCB layouts. Verify that the 10 V maximum supply rating exceeds the system's peak voltage conditions.

Supervisors Part Context

This part belongs to the LP3470A family of voltage supervisors designed for high-accuracy power management. It serves as a direct upgrade to previous generations with improved threshold precision. The device integrates essential reset functionality without requiring additional manual reset inputs or watchdog timers, simplifying circuit design for standard supervisory roles.

Supervisors Replacement Considerations

LP3470A293DBVT is the tape-and-reel equivalent of the DBVR cut-tape version. LP3470M5-2.93/NOPB offers similar functionality but may differ in temperature range and supply voltage limits; verify compatibility before substitution.
