LM3710YQMM-232/NOPB

Supervisors Overview

The LM3710YQMM-232/NOPB is a voltage supervisor and reset IC manufactured by Texas Instruments. It features an adjustable output threshold with a factory-set trip point of 2.32V, ensuring precise monitoring of power supply rails. The device includes a programmable delay timer ranging from 50ms to 640s for controlled reset assertion. It operates within a supply voltage range of 1.2V to 5.5V and draws a maximum quiescent current of 10µA. The component is housed in a VSSOP-8 package and supports automotive applications with AEC-Q100 qualification.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a fixed 2.32V threshold for reliable power supervision
• Features a user-programmable external capacitor delay timer allowing flexible reset timing configurations
• Provides a push-pull active-low reset output compatible with various digital logic families

Supervisors Applications

• Automotive electronic control unit (ECU) power management systems
• Battery-powered portable devices requiring low standby current
• Industrial embedded systems needing robust brown-out protection

Supervisors Procurement Notes

Verify the specific suffix '232' confirms the 2.32V trip voltage setting required for your design. Ensure the 'NOPB' designation indicates lead-free and RoHS compliance status. Confirm the 'YQ' prefix aligns with the required automotive reliability standards and extended temperature range specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.32V supervision threshold is necessary rather than an adjustable resistor network. Consider the programmable delay feature if system startup sequencing requires specific timing margins. Evaluate the low quiescent current consumption against battery life requirements for portable applications.

Supervisors Part Context

This part belongs to the LM3710 family of voltage supervisors designed for critical power monitoring tasks. It replaces older discrete monitoring solutions by integrating threshold detection and reset generation into a single compact integrated circuit. The automotive-grade variant ensures durability under harsh environmental conditions typical in vehicle electronics.

Supervisors Replacement Considerations

Direct substitutes include other LM3710 variants with different voltage thresholds or delay capabilities. Verify pin compatibility and electrical characteristics when considering alternative manufacturers' voltage supervisors.
