Product details
Overview
MAX6375XR31+ from Maxim Integrated is an ultra-low-power, active-low voltage detector in SC70-3 package, designed for precision supply monitoring in battery-powered systems. It features a factory-trimmed 3.08V threshold (±2.5% over temperature), 500nA supply current, and push-pull output that asserts logic low when VCC falls below VTH. Used in portable equipment power sequencing and microcontroller reset supervision.
For engineers reviewing the MAX6375XR31+ datasheet, MAX6375XR31+ pinout, MAX6375XR31+ application, or MAX6375XR31+ equivalent, key selection criteria include threshold accuracy, ultra-low quiescent current, transient immunity, and compatibility with 1.2V–5.5V VCC operation and open-drain/push-pull interface requirements.
Technical Context
The MAX6375XR31+ implements a precision bandgap reference and comparator with internally trimmed resistors to set its 3.08V detection threshold. Its push-pull output drives actively high or low without external pull-up, and it guarantees correct logic state down to VCC = 1V.
Designed to reject fast negative-going VCC transients, the device specifies maximum allowable glitch duration versus threshold overdrive (e.g., ≤20µs for 100mV overdrive). Propagation delay is 6.3µs (typ) at +25°C with 200mV overdrive, and hysteresis is 0.1mV - enabling stable reset assertion without chatter during brownout recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Threshold Voltage | 3.08V ±2.5% over -40°C to +85°C - ensures reliable reset assertion across industrial temperature range |
| Supply Current | 500nA typical at +25°C - enables multi-year battery life in coin-cell–powered devices |
| Output Type | Active-low push-pull - eliminates need for external pull-up resistor and supports direct MCU reset input |
| VCC Operating Range | 1.2V to 5.5V - supports operation during deep brownout and across diverse supply rails |
| Propagation Delay | 6.3µs typical (falling edge, VOD = 200mV) - provides fast response to supply collapse while avoiding false triggers |
| Threshold Hysteresis | 0.1mV - minimizes sensitivity to noise near trip point without compromising detection resolution |
| Tempco | 40ppm/°C - maintains tight threshold stability across temperature without calibration |
Pinout & Package
MAX6375XR31+ is housed in a 3-pin SC70-3 package (2.0mm × 2.1mm × 0.95mm), optimized for space-constrained portable designs. The package is lead-free, tape-and-reel compatible, and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal bandgap and comparator - must be low-impedance connection to system ground plane |
| 2 | OUT | Active-low push-pull output - sinks current when asserted (VCC < VTH); drives logic low directly into MCU reset pin |
| 3 | VCC | Supply input - powers internal circuitry; operates from 1.2V to 5.5V; monitors this rail for undervoltage condition |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 500nA supply current | Extends battery service life in always-on monitoring applications such as wearables and IoT sensors |
| ±2.5% threshold accuracy over temperature | Eliminates need for external trimming or calibration in production, reducing BOM and test cost |
| Factory-trimmed 3.08V threshold | Matches common Li-ion battery discharge end-point (3.0–3.1V), enabling precise EOL detection |
| Push-pull active-low output | Directly interfaces with standard microcontroller reset inputs without pull-up resistor or level-shifting |
| Immunity to VCC transients ≤20µs | Prevents spurious resets during switching noise or load-dump events in DC/DC converter outputs |
Applications
| Portable Battery-Powered Device | Microcontroller Reset Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB30DBZR | 3.0V threshold, 350nA ICC, SOT23-3, open-drain output | Requires external pull-up; lower threshold and current, but no push-pull drive | Select when lowest possible current is critical and system can accommodate open-drain interface |
| TPS3801K30DBVR | 3.0V threshold, 1.6µA ICC, SOT23-5, active-low push-pull, higher supply current | Includes manual reset input and watchdog timer - adds functionality but increases complexity and power | Select when additional supervisory features (e.g., manual reset) are required beyond basic voltage detection |
Compared with TLV803EB30DBZR and TPS3801K30DBVR, the MAX6375XR31+ uniquely balances ultra-low 500nA current, factory-trimmed 3.08V threshold, and push-pull output in a 3-pin SC70 - making it optimal for compact, battery-sensitive designs where simplicity and minimal external components are mandatory.

FAQ
What is the exact factory-trimmed threshold voltage of the MAX6375XR31+?
The MAX6375XR31+ has a nominal threshold voltage of 3.08V, with ±2.5% accuracy over the full -40°C to +85°C operating temperature range. This value is laser-trimmed at wafer test and confirmed per Table 1 in the datasheet, where suffix "R31" explicitly denotes the 3.08V variant within the MAX6375 series.
Does the MAX6375XR31+ require an external pull-up resistor on its OUT pin?
No, the MAX6375XR31+ features an active-low push-pull output, meaning it actively drives both high and low states without needing an external pull-up resistor. This simplifies PCB layout and reduces BOM count compared to open-drain alternatives like the MAX6377XR31+.
Can the MAX6375XR31+ operate reliably below 2.0V VCC?
Yes - the MAX6375XR31+ is fully specified to guarantee correct output logic state down to VCC = 1.0V, and its internal bandgap reference remains functional across the full 1.2V to 5.5V operating range. This makes it suitable for deep brownout detection in low-voltage systems.
What is the propagation delay of the MAX6375XR31+ during a falling VCC event?
The MAX6375XR31+ exhibits a typical propagation delay of 6.3µs (falling edge) when VCC drops below the 3.08V threshold with 200mV overdrive, measured at +25°C. This delay is consistent across the MAX6375/MAX6376/MAX6377 group and ensures timely reset assertion without excessive latency.
Is the MAX6375XR31+ pin-compatible with other variants in the MAX6375–MAX6380 family?
Yes - all MAX6375–MAX6380 devices share identical SC70-3 and SOT23-3 pinouts. The MAX6375XR31+ uses Pin 1 = GND, Pin 2 = OUT, Pin 3 = VCC, matching the pin configuration shown in the datasheet's top-view diagrams for both packages.
