Product details
Overview
MAX6375XR31+T from Maxim Integrated is an ultra-low-power, active-low voltage detector in SC70-3 package with factory-trimmed 3.08V threshold, ±2.5% accuracy over temperature, 500nA supply current, and push-pull output. It monitors VCC in portable battery-powered systems and asserts OUT low when supply falls below threshold.
For engineers reviewing the MAX6375XR31+T datasheet, MAX6375XR31+T pinout, MAX6375XR31+T application, or MAX6375XR31+T equivalent, key selection criteria include reset threshold tolerance, supply current at ultra-low VCC (down to 1V), transient immunity, open-drain vs. push-pull logic compatibility, and SC70 footprint constraints in space-constrained designs.
Technical Context
The MAX6375XR31+T implements a precision bandgap reference and comparator with internally trimmed resistors to set its 3.08V trip point-no external components required. Its push-pull output drives logic directly without pull-up resistors and remains valid down to VCC = 1V.
Designed for immunity to fast transients, it suppresses output pulses for negative-going VCC glitches up to duration inversely proportional to overdrive (e.g., ~140µs at 100mV overdrive). Propagation delay is 6.3µs (typ) for falling edge at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08V ±2.5% over -40°C to +85°C - ensures reliable brown-out detection across industrial temperature range |
| Supply Current | 500nA typical at +25°C - enables multi-year operation on coin-cell batteries |
| Output Type | Active-low push-pull - drives CMOS/TTL loads directly; no external pull-up needed |
| VCC Operating Range | 1.2V to 5.5V - supports operation during deep brown-out and post-reset recovery |
| Propagation Delay | 6.3µs typical (falling edge) - provides timely reset assertion without excessive latency |
| Threshold Hysteresis | 100mV - prevents chatter near trip point during slow VCC recovery |
| Tempco | 40ppm/°C - limits drift-induced false triggers in thermally varying environments |
Pinout & Package
MAX6375XR31+T is housed in a 3-pin SC70-3 package (2.0mm × 2.1mm × 0.9mm), optimized for ultra-compact PCB layouts in wearables and IoT sensors.
| 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 microcontroller RESET or enable inputs directly |
| 3 | VCC | Supply input; powers internal circuitry and sets detection domain; operates down to 1.2V with full functionality |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 500nA enables >10-year battery life in always-on monitoring applications |
| Factory-trimmed threshold | 3.08V with ±2.5% tolerance eliminates calibration overhead and BOM cost of external resistors |
| Push-pull output stage | Drives high- and low-side logic without external pull-up, reducing component count and board area |
| Transient-immune design | Rejects VCC glitches ≤140µs (at 100mV overdrive), preventing spurious resets in noisy power domains |
| Wide VCC operating range | Functions reliably from 1.2V to 5.5V, supporting Li-ion, coin-cell, and regulated 3.3V/5V rails |
Applications
| Battery Voltage Monitoring | Microcontroller Power-On Reset |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3123QDBVRQ1 | 3.08V threshold, ±1.5% accuracy, 1.8µA supply current, SOT23-3 package | Higher supply current reduces battery life; automotive AEC-Q100 qualified | Select for automotive-grade designs where qualification outweighs ultra-low-power requirement |
| APX803SA-30SA-7 | 3.0V threshold, ±2% accuracy, 450nA supply current, SOT23-3 package | 0.08V lower threshold; identical SC70/SOT23 footprint but not pin-compatible due to different pin 1 assignment (GND vs VCC) | Choose when 3.0V trip is acceptable and SOT23-3 layout reuse is prioritized over SC70 size reduction |
Compared with TPS3123QDBVRQ1 and APX803SA-30SA-7, the MAX6375XR31+T delivers tighter thermal stability (40ppm/°C vs ≥60ppm/°C), lower supply current than automotive alternatives, and SC70-3 footprint advantage for miniaturized PCBs-making it optimal for consumer wearables and long-life battery systems where size and quiescent power are critical.

FAQ
What is the exact reset threshold voltage of the MAX6375XR31+T and how tightly is it specified?
The MAX6375XR31+T has a factory-trimmed nominal reset threshold of 3.08V, guaranteed over temperature from -40°C to +85°C with ±2.5% tolerance (i.e., 2.925V to 3.150V). This specification is verified per Electrical Characteristics table in the official datasheet and applies under all operating conditions within the rated VCC range.
Does the MAX6375XR31+T require external components to operate?
No, the MAX6375XR31+T requires no external components. Its precision bandgap reference, comparator, and threshold-setting resistors are fully integrated and factory-trimmed. The device functions immediately upon connection of VCC and GND, with OUT driving logic directly-no pull-up resistors, capacitors, or trimming networks are needed.
What is the minimum VCC voltage at which the MAX6375XR31+T guarantees correct output state?
The MAX6375XR31+T guarantees correct output logic state (active-low assertion when VCC < VTH) down to VCC = 1V. This is explicitly stated in the General Description and confirmed in the Absolute Maximum Ratings and Electrical Characteristics sections of the datasheet, enabling reliable operation during deep brown-out conditions.
How does the MAX6375XR31+T handle fast transients on the VCC line?
MAX6375XR31+T incorporates built-in transient immunity: it ignores negative-going VCC glitches whose duration is below a threshold inversely related to overdrive magnitude (e.g., ≤140µs for 100mV overdrive). This behavior is characterized in the Typical Operating Characteristics graph "Maximum Transient Duration vs. Threshold Overdrive" and prevents false resets in electrically noisy environments.
Is the MAX6375XR31+T pin-compatible with other devices in the MAX6375–MAX6380 family?
Yes, all MAX6375–MAX6380 variants-including MAX6375XR31+T-are pin-compatible within the same package type (SC70-3 or SOT23-3). Pin 1 is GND, Pin 2 is OUT, and Pin 3 is VCC across the entire family. However, output logic (active-low push-pull for MAX6375/MAX6378) differs from active-high (MAX6376/MAX6379) and open-drain (MAX6377/MAX6380), so functional substitution requires verification of logic polarity and drive strength.
