Product details
Overview
LM8364BALMFX30/NOPB from Texas Instruments is a micropower undervoltage sensing circuit with 3.0V detection threshold (±2.5% accuracy), 0.65μA quiescent current at VIN = 2.87V, and active-low open-drain RESET output - designed for battery-powered microprocessor reset control in portable embedded systems.
For engineers reviewing the LM8364BALMFX30/NOPB datasheet, LM8364BALMFX30/NOPB pinout, LM8364BALMFX30/NOPB application, or LM8364BALMFX30/NOPB equivalent, key selection criteria include precise 3.0V threshold hysteresis (0.150V typ), operation down to 1.0V supply, SOT-23-5 package compatibility, and verified performance across −40°C to +85°C.
Technical Context
The LM8364BALMFX30/NOPB integrates a precision voltage reference, comparator with built-in hysteresis (VHYS = 0.090–0.210V), and open-drain output stage. It monitors input voltage (PIN 2) against a factory-trimmed 3.0V threshold (VDET− = 2.925–3.075V) and asserts RESET low when VIN falls below VDET−, holding low until VIN rises above VDET+ = VDET− + VHYS.
Its ultra-low quiescent current (0.65μA typ at 2.87V) enables long-term battery monitoring without significant drain, while propagation delay (60–300μs) and output sink capability (1.0–2.5mA at VOL = 0.5V) support reliable microcontroller reset timing in low-power systems.

FAQ
What is the exact detection threshold voltage of LM8364BALMFX30/NOPB?
The LM8364BALMFX30/NOPB has a factory-trimmed detection threshold of 3.0V with ±2.5% accuracy (2.925V to 3.075V at TA = 25°C). This value is specified as VDET− in the Electrical Characteristics table and remains stable across −40°C to +85°C with a temperature coefficient of ±100 ppm/°C.
Does LM8364BALMFX30/NOPB require an external pull-up resistor on the RESET pin?
Yes, LM8364BALMFX30/NOPB features an open-drain RESET output and requires an external pull-up resistor to a valid supply rail (≤6.5V). Typical values range from 47kΩ to 470kΩ depending on rise time and bus loading requirements; TI recommends 470kΩ to VIN for ultra-low current applications.
Can LM8364BALMFX30/NOPB operate from a 1.2V supply?
Yes, LM8364BALMFX30/NOPB is fully functional down to 1.0V input voltage. At 1.2V, it maintains accurate 3.0V threshold detection and delivers guaranteed RESET assertion with propagation delay within specification (60–300μs), enabling use in deeply discharged battery scenarios.
What is the maximum sink current capability of the RESET output in LM8364BALMFX30/NOPB?
The RESET output of LM8364BALMFX30/NOPB can sink up to 2.5mA while maintaining VOL ≤ 0.5V (tested at VIN = 1.5V). Absolute maximum rating is 70mA, but sustained operation above 2.5mA may degrade long-term reliability and is not characterized across temperature.
Is LM8364BALMFX30/NOPB pin-compatible with other members of the LM8364 family?
Yes, all LM8364 variants-including LM8364BALMFX20/NOPB, LM8364BALMFX27/NOPB, and LM8364BALMFX45/NOPB-share identical SOT-23-5 (DBV) pinout, electrical interface, and functional behavior. Only the detection threshold differs between suffixes; no PCB changes are required when substituting within the family.
