Product details
Overview
MAX6376XR30-T from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector IC designed for precision supply monitoring in battery-powered systems. It features a factory-trimmed 3.00V threshold (±2.5% over temperature), 500nA supply current, and guaranteed operation down to 1V VCC. It asserts a logic-high output when VCC falls below the threshold and is used in portable equipment power sequencing and microcontroller reset supervision.
For engineers reviewing the MAX6376XR30-T datasheet, MAX6376XR30-T pinout, MAX6376XR30-T application, or MAX6376XR30-T equivalent, this page delivers verified specifications, SC70-3 package details, real-world use scenarios, and two validated alternative parts with documented functional and application differences.
Technical Context
The MAX6376XR30-T implements a precision bandgap reference and comparator with internally trimmed resistors to set its 3.00V trip point. Its active-high push-pull output drives high without external pull-up, simplifying interface with 1.8V–5V logic domains.
It incorporates transient immunity circuitry that rejects fast negative-going VCC glitches up to 200µs at 100mV overdrive, and guarantees correct output state across -40°C to +85°C while consuming only 500nA typical supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.00V ±2.5% over -40°C to +85°C - ensures reliable brown-out detection for 3.3V or Li-ion systems. |
| Supply Current | 500nA typical - enables multi-year battery life in coin-cell–powered IoT sensors and wearables. |
| Output Type | Active-high push-pull - eliminates need for external pull-up resistor, reducing BOM count and PCB area. |
| VCC Operating Range | 1.2V to 5.5V - supports operation during deep brown-out and compatibility with wide-input DC/DC converters. |
| Propagation Delay | 6.3µs typical (falling edge) - provides fast response to supply faults without false triggering on noise. |
| Threshold Hysteresis | 100mV - prevents output oscillation during slow VCC recovery near trip point. |
| Tempco | 40ppm/°C - maintains tight threshold stability across industrial temperature range. |
Pinout & Package
MAX6376XR30-T 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 and RoHS-compliant, supplied in tape-and-reel format.
| 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-high push-pull output - sources up to 500µA and sinks up to 1.2mA; directly interfaces with µP reset inputs or enable pins. |
| 3 | VCC | Supply input - powers internal circuitry; operates from 1.2V to 5.5V and defines monitored rail. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low 500nA supply current | Extends battery life in always-on monitoring applications such as smart locks and medical patches. |
| ±2.5% threshold accuracy over temperature | Eliminates need for calibration or margining in production test for 3.0V nominal systems. |
| Active-high push-pull output | Reduces component count by removing external pull-up resistor and avoids bus contention in shared reset lines. |
| 1.2V minimum VCC operation | Ensures valid reset assertion even during deep discharge of single-cell Li-ion or alkaline batteries. |
| SC70-3 footprint | Matches SOT23-3 layout for drop-in replacement flexibility while offering smaller thermal mass and lower parasitic inductance. |

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 supply current, open-drain output, SOT23-3 only. | Requires external pull-up; not pin-compatible due to different output polarity and drive type. | Select when lowest possible current is critical and system already uses pull-up architecture. |
| APX803S-30SA-7 | 3.0V threshold, 1.1µA supply current, active-high push-pull, SOT23-3 only. | Higher quiescent current; same output behavior but larger package footprint than SC70-3. | Select when SC70-3 assembly capability is unavailable and 1.1µA is acceptable for target battery life. |
Compared with MAX6376XR30-T, TLV803EB30DBZR offers lower current but requires board-level redesign for pull-up support, while APX803S-30SA-7 matches output behavior but increases solution size and doubles supply current-making MAX6376XR30-T optimal for ultra-compact, ultra-low-power designs requiring active-high push-pull in SC70.

FAQ
What is the exact reset threshold voltage of the MAX6376XR30-T?
The MAX6376XR30-T has a nominal reset threshold of 3.00V, with guaranteed accuracy of ±2.5% over the full operating temperature range (-40°C to +85°C). At +25°C, the typical threshold is 3.00V, and the device maintains this specification across its 1.2V to 5.5V VCC range. This value is factory-trimmed and does not require external calibration - the "R30" suffix in MAX6376XR30-T explicitly denotes the 3.00V variant.
Does the MAX6376XR30-T require an external pull-up resistor on its OUT pin?
No, the MAX6376XR30-T does not require an external pull-up resistor because it features an active-high push-pull output stage. Unlike open-drain detectors, this configuration actively drives the OUT pin high (up to 0.8×VCC) when VCC falls below 3.00V and low (≤0.4V) otherwise. This eliminates BOM cost and layout area associated with external resistors and ensures robust interfacing with standard CMOS reset inputs.
Can the MAX6376XR30-T operate reliably at VCC = 1.2V?
Yes, the MAX6376XR30-T is fully specified to operate and assert its output correctly down to VCC = 1.2V. Its internal bandgap reference and comparator remain functional across this range, and the output maintains valid logic levels (VOH ≥0.8×VCC, VOL ≤0.4V) even at minimum supply. This capability is critical for detecting brown-out conditions in deeply discharged single-cell battery systems where voltage may dip to 1.2V before shutdown.
What is the supply current consumption of the MAX6376XR30-T at room temperature?
The MAX6376XR30-T consumes 500nA typical supply current at +25°C, with a maximum of 1.0µA over temperature. This ultra-low quiescent current is measured with no load on the OUT pin and VCC within specification. It enables multi-year operation on coin-cell batteries - for example, a CR2032 (220mAh) could power the MAX6376XR30-T continuously for over 28 years at 500nA average draw.
Is the MAX6376XR30-T pin-compatible with other devices in the MAX6375–MAX6380 family?
Yes, the MAX6376XR30-T shares identical pinout (GND, OUT, VCC) and SC70-3 package dimensions with all MAX6375–MAX6380 variants in the XR suffix series. However, output logic polarity differs: MAX6376/MAX6379 are active-high push-pull, while MAX6375/MAX6378 are active-low push-pull and MAX6377/MAX6380 are active-low open-drain. Therefore, direct substitution requires verification of output polarity and drive strength requirements in the target circuit.
