Product details
Overview
MAX6376XR27-T from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector designed for precision supply monitoring in battery-powered systems. It features a factory-trimmed 2.70V threshold (±2.5% over temperature), 500nA supply current at +25°C, and guaranteed operation down to VCC = 1V. Its role is to assert a logic-high output when VCC falls below the threshold, enabling reliable power-fail detection in portable medical devices.
For engineers reviewing the MAX6376XR27-T datasheet, MAX6376XR27-T pinout, MAX6376XR27-T application, or MAX6376XR27-T equivalent, this device is selected for low-quiescent-current reset supervision where active-high assertion, SC70-3 packaging, and transient-immune threshold detection are required.
Technical Context
The MAX6376XR27-T implements a precision bandgap reference and comparator with internally trimmed resistors to set its 2.70V trip point. It uses no external components and ignores fast VCC transients-its maximum tolerable negative-going glitch duration is ≤140µs at 100mV overdrive (VTH − VCC).
This device belongs to the MAX6375–MAX6380 family of single-function voltage detectors. Unlike open-drain or active-low variants, the MAX6376XR27-T provides push-pull active-high output logic, sourcing up to 500µA at VCC ≥ 2.1V while asserted, with VOL ≤ 0.4V at ISINK = 1.2mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.70V ±2.5% over −40°C to +85°C - ensures accurate brownout detection across industrial temperature range |
| Supply Current | 500nA typical at +25°C - enables multi-year battery life in coin-cell–powered IoT sensors |
| Output Type | Active-high push-pull - drives logic inputs directly without pull-up resistor, reducing BOM count |
| VCC Operating Range | 1.2V to 5.5V - supports supervision of Li+ batteries (2.7–4.2V) and 3.3V/5V rails |
| Propagation Delay | 6.3µs typical (falling edge) - provides timely reset assertion during rapid supply collapse |
| Threshold Hysteresis | 100mV - prevents output chatter near trip point during slow-ramping or noisy supplies |
| Package | 3-pin SC70-3 - 2.0mm × 2.1mm footprint ideal for space-constrained wearables |
Pinout & Package
MAX6376XR27-T is housed in a 3-pin SC70-3 package (2.0mm × 2.1mm × 0.95mm height), compatible with standard SOT23-3 reflow profiles but with reduced footprint. Pin 1 is OUT, Pin 2 is GND, Pin 3 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Active-high push-pull output | Drives logic-high signal when VCC < 2.70V; sinks 1.2mA / sources 500µA; no external pull-up needed |
| 2 (GND) | Analog ground reference | Must be connected to clean system ground plane; shares return path with VCC decoupling |
| 3 (VCC) | Supply input | Accepts 1.2V–5.5V; internal ESD protection rated to ±2kV HBM; requires local 0.1µF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 500nA max at +25°C - extends shelf life and runtime in always-on battery backup circuits |
| Factory-trimmed VTH | 2.70V with ±2.5% tolerance over full temperature range - eliminates manual calibration or trimming resistors |
| Transient immunity | Rejects VCC glitches ≤140µs at 100mV overdrive - prevents false resets during switching noise or load dumps |
| No external components | Self-contained reference, comparator, and threshold network - reduces PCB area and qualification effort |
| Guaranteed state down to 1V | Valid output logic maintained even as VCC collapses to 1V - ensures deterministic reset behavior during deep brownout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB27DBZR | 2.7V threshold, 350nA ICC, SOT23-3, open-drain active-low output | Requires external pull-up; not pin-compatible; lower supply current but inverted logic | Select when open-drain interface or sub-350nA ICC is mandatory and logic inversion is acceptable |
| APX803S-27SA-7 | 2.7V threshold, 800nA ICC, SOT23-3, push-pull active-high output, ±2% accuracy | Same logic polarity and package; higher ICC and tighter accuracy; wider VCC range (0.9–6.0V) | Choose when tighter threshold tolerance (±2%) is critical and 800nA ICC remains acceptable |
Compared with TLV803EB27DBZR and APX803S-27SA-7, the MAX6376XR27-T uniquely balances ultra-low 500nA current, SC70-3 miniaturization, and guaranteed 1V operation-making it optimal for space- and energy-constrained designs where active-high push-pull drive is required without layout changes.

FAQ
What is the exact reset threshold voltage of the MAX6376XR27-T?
The MAX6376XR27-T has a nominal reset threshold of 2.70V, with guaranteed tolerance of ±2.5% over the full operating temperature range (−40°C to +85°C). At +25°C, the typical threshold is 2.70V, and the min/max limits are 2.633V and 2.768V respectively per Table 1 in the datasheet.
Does the MAX6376XR27-T require any external components to operate?
No, the MAX6376XR27-T requires no external components. It integrates a precision bandgap reference, comparator, and factory-trimmed resistor network to set its 2.70V threshold. A local 0.1µF ceramic capacitor on VCC is recommended for stability but is not functionally required for basic operation.
What is the output configuration of the MAX6376XR27-T and how does it interface with a microcontroller?
The MAX6376XR27-T features an active-high push-pull output. When VCC falls below 2.70V, OUT asserts logic high; when VCC is above threshold, OUT is logic low. This allows direct connection to an MCU's active-high reset input without pull-up resistors or level shifters.
Can the MAX6376XR27-T operate reliably at very low supply voltages?
Yes, the MAX6376XR27-T guarantees correct output logic state down to VCC = 1V, and operates across 1.2V to 5.5V. This ensures deterministic reset behavior during deep brownout conditions common in battery discharge profiles, unlike many competitors that fail below 1.8V.
What package options are available for the MAX6376XR27-T and are they interchangeable?
The MAX6376XR27-T is offered exclusively in the 3-pin SC70-3 package (top mark "-" per Table 2). While the MAX6376UR27-T uses the same die in SOT23-3, the SC70-3 variant is not pin-to-pin or footprint interchangeable due to different pad layout and dimensions-PCB redesign is required for substitution.
