Product details
Overview
LM8364BALMF30/NOPB from Texas Instruments is a micropower undervoltage sensing circuit with 3.0 V ±2.5% threshold, 0.65 μA quiescent current at VIN = 2.87 V, open-drain active-low RESET output, and operation down to 1.0 V input - designed for battery-powered microprocessor reset supervision in portable embedded systems.
For engineers reviewing the LM8364BALMF30/NOPB datasheet, LM8364BALMF30/NOPB pinout, LM8364BALMF30/NOPB application, or LM8364BALMF30/NOPB equivalent, key selection criteria include threshold accuracy over temperature (±100 ppm/°C), built-in 0.150 V hysteresis, SOT-23-5 package compatibility, and guaranteed reset assertion below 1.0 V supply.
Technical Context
The LM8364BALMF30/NOPB integrates a precision voltage reference, comparator with trimmed detection threshold, and internal hysteresis to prevent oscillation near VDET−. It operates across −40°C to +85°C with thermal resistance θJA = 265°C/W and requires no external components beyond a pull-up resistor on the open-drain RESET output.
Its input voltage range spans 1.0 V to 6.0 V, enabling use in single-cell Li-ion, multi-cell alkaline, or low-voltage logic rails. Propagation delay is specified at 60–300 μs with 470 kΩ pull-up and 10 pF load, and output sink capability reaches 2.5 mA at VIN = 1.5 V and VOL = 0.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Threshold Voltage | 3.0 V ±2.5% (VDET−), ensuring reliable reset activation at precisely defined supply drop |
| Quiescent Current | 0.65 μA typical at VIN = 2.87 V - enables multi-year battery life in always-on monitoring |
| Hysteresis | 0.150 V typical (VHYS) - prevents chatter during slow or noisy supply recovery |
| Input Range | 1.0 V to 6.0 V - supports single-cell LiFePO₄ (2.0–3.6 V), 3.3 V logic, and dual-cell alkaline (up to ~3.2 V) |
| Output Type | Active-low open-drain RESET - allows wired-OR configuration and flexible pull-up voltage selection |
| Temp Coefficient | ±100 ppm/°C - maintains threshold stability across industrial temperature range |
| Propagation Delay | 60–300 μs - ensures timely system reset without excessive latency or false triggering |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, gull-wing leads, RoHS-compliant matte tin lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Open-drain output | Active-low reset signal; requires external pull-up; sinks up to 2.5 mA at 1.5 V supply |
| 2 - INPUT | Voltage sense input | Monitors supply rail; threshold detection occurs when VIN falls below 3.0 V (VDET−) |
| 3 - GND | Ground reference | Analog and digital ground return; must be low-impedance connection for accurate threshold tracking |
| 4 - N/C | No connect | Internally unconnected; must remain floating or tied to GND per layout guidelines |
| 5 - N/C | No connect | Internally unconnected; must remain floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |

Applications
| Battery-Powered Microcontroller Reset | Low-Voltage Power Fail Detection |
|---|---|
Use Scenario: Portable medical sensor with CR2032 coin cell powering an ARM Cortex-M0+ MCU. IC Role / Device Role / Timing Role: Monitors VDD and asserts active-low RESET when voltage drops below 3.0 V to prevent corrupted flash writes or RAM loss. Use Value: 0.65 μA quiescent current extends battery life by >30% versus higher-current supervisors; hysteresis avoids repeated resets during marginal supply recovery. | Use Scenario: Industrial PLC I/O module with dual 3.3 V/5 V supplies requiring coordinated power-fail signaling. IC Role / Device Role / Timing Role: Detects undervoltage on primary 3.3 V rail and triggers controlled data save before backup capacitor depletes. Use Value: Guaranteed operation down to 1.0 V input ensures reset assertion even as bulk capacitance discharges below LDO dropout. |
| Single-Cell Li-ion Voltage Monitor | Backup Power Supervision |
Use Scenario: Wearable fitness tracker using single-cell Li-ion (2.8–4.2 V) with fuel gauge and sleep-mode wake-up logic. IC Role / Device Role / Timing Role: Triggers system shutdown when cell voltage falls to 3.0 V, preserving minimum charge for safe recharge initiation. Use Value: ±2.5% threshold accuracy prevents premature shutdown above usable capacity; ±100 ppm/°C drift ensures consistent behavior across operating temperature. | Use Scenario: Smart meter with supercapacitor backup maintaining real-time clock and nonvolatile registers during AC mains failure. IC Role / Device Role / Timing Role: Supervises supercapacitor voltage and asserts RESET when falling below 3.0 V to initiate data flush and enter ultra-low-power retention mode. Use Value: Open-drain output allows direct interface to microcontroller's dedicated reset pin while sharing pull-up with other supervisory circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar undervoltage sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB30DBVR | 3.0 V threshold, 0.5 μA IQ, but only rated down to 1.5 V input (not 1.0 V) | Lacks guaranteed reset assertion below 1.5 V - unsuitable for deep brown-out scenarios | Select if lower quiescent current is prioritized and minimum operating voltage ≥1.5 V |
| MAX809SEUR+T | 3.08 V threshold, 12 μA IQ, push-pull output (not open-drain) | Higher current draw reduces battery life; push-pull limits wiring flexibility vs. open-drain | Select if board already uses push-pull reset architecture and 12 μA IQ is acceptable |
Compared with TLV803EB30DBVR and MAX809SEUR+T, the LM8364BALMF30/NOPB uniquely combines sub-μA quiescent current, 1.0 V operational floor, and open-drain output - making it optimal for long-life, low-voltage, and multi-rail reset coordination designs.

FAQ
What is the exact threshold voltage tolerance of the LM8364BALMF30/NOPB?
The LM8364BALMF30/NOPB has a detector threshold voltage (VDET−) of 3.0 V with a guaranteed tolerance of ±2.5%, meaning the actual trip point falls between 2.925 V and 3.075 V at 25°C. This specification is ensured across the full operating temperature range of −40°C to +85°C, with additional drift limited to ±100 ppm/°C.
Does the LM8364BALMF30/NOPB require external components to function?
No, the LM8364BALMF30/NOPB operates autonomously with only an external pull-up resistor on the RESET pin. The device integrates a precision voltage reference, comparator, and hysteresis - eliminating need for external resistors, capacitors, or bias networks. A 470 kΩ pull-up to VIN or another rail is recommended for timing compliance per the datasheet.
Can the LM8364BALMF30/NOPB assert reset when supply voltage drops below 1.5 V?
Yes - the LM8364BALMF30/NOPB is fully specified to operate and assert RESET down to 1.0 V input voltage. Its internal circuitry remains functional and guarantees correct threshold comparison and output state transition even at 1.0 V, unlike many competitors that cease operation above 1.5 V.
What is the maximum sink current capability of the LM8364BALMF30/NOPB RESET pin?
The RESET pin of the LM8364BALMF30/NOPB can sink up to 2.5 mA when VIN = 1.5 V and VOL = 0.5 V. At higher supply voltages (e.g., VIN = 3.3 V), sink current increases slightly but remains within the 70 mA absolute maximum rating. For standard microcontroller reset inputs, a 10–100 kΩ pull-up suffices.
Is the LM8364BALMF30/NOPB pin-compatible with the MC33464 series?
Yes - the LM8364BALMF30/NOPB is explicitly stated in its datasheet as pin-for-pin compatible with the MC33464 family. Both devices use identical SOT-23-5 pinout (RESET, INPUT, GND, N/C, N/C), enabling direct substitution without PCB modification, provided the threshold voltage and hysteresis requirements align.
