Product details
Overview
MAX6376XR22+ 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 2.20V 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 threshold and is used in portable equipment power sequencing and microcontroller reset supervision.
For engineers reviewing the MAX6376XR22+ datasheet, MAX6376XR22+ pinout, MAX6376XR22+ application, or MAX6376XR22+ equivalent, key selection criteria include its active-high push-pull output configuration, SC70-3 package, 2.20V trip point, transient immunity, and compatibility with low-voltage microcontrollers requiring clean reset assertion during brownout conditions.
Technical Context
The MAX6376XR22+ implements a precision bandgap reference and comparator with internally trimmed resistors to set its 2.20V detection threshold. Its active-high push-pull output drives high (VOH ≥ 0.8×VCC) when VCC drops below VTH and low (VOL ≤ 0.4V at 1.2mA sink) otherwise, eliminating external pull-up components.
It operates across -40°C to +85°C with ±2.5% threshold accuracy and 40ppm/°C tempco, and rejects fast VCC transients via built-in hysteresis (100mV typical) and propagation delay filtering (20µs typical falling edge). No external components are required for basic operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.20V ±2.5% over -40°C to +85°C - sets precise brownout detection point for 2.4–2.8V nominal battery systems |
| Supply Current | 500nA typical - enables multi-year battery life in always-on monitoring applications |
| Output Type | Active-high push-pull - provides rail-to-rail logic-level output without external pull-up resistor |
| VCC Operating Range | 1.2V to 5.5V - supports operation during deep brownout and compatibility with 1.8V/3.3V/5V systems |
| Propagation Delay | 20µs typical (falling edge) - ensures stable reset assertion without chatter on slow-supply ramps |
| Threshold Hysteresis | 100mV typical - prevents output oscillation during noisy or slowly recovering supply conditions |
| Tempco | 40ppm/°C - maintains tight threshold stability across industrial temperature range |
Pinout & Package
MAX6376XR22+ 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 (denoted by '+' suffix).
| 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 - drives high (≥0.8×VCC) when VCC < 2.20V; sinks up to 1.2mA when deasserted |
| 3 | VCC | Supply input - powers internal circuitry and defines detection domain; operates from 1.2V to 5.5V |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 500nA enables >10-year coin-cell battery life in always-monitoring mode |
| Factory-trimmed threshold | 2.20V with ±2.5% tolerance eliminates calibration overhead and external resistor networks |
| Push-pull active-high output | Direct interface to 1.8V/3.3V microcontroller reset inputs without pull-up or level-shifting |
| Transient immunity | Rejects VCC glitches <20µs duration at 2.1V (100mV overdrive), preventing false resets |
| Full-temperature operation | Guaranteed functionality from -40°C to +85°C with no output state ambiguity down to 1V VCC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803R22DBVR | 2.2V threshold, open-drain active-low output, 350nA supply current, SOT23-3 only | Requires external pull-up; incompatible with active-high reset inputs without inversion logic | Select when lowest possible current is critical and system design accommodates active-low signaling |
| APX803S-22SA-7 | 2.2V threshold, push-pull active-low output, 650nA supply current, SOT23-3 only | Asserts low on fault - requires inverter or MCU with active-low reset pin; no SC70 option | Select when board layout already uses SOT23-3 and active-low reset architecture is fixed |
Compared with TLV803R22DBVR and APX803S-22SA-7, the MAX6376XR22+ uniquely delivers active-high push-pull output in SC70-3 with industry-leading 500nA current and guaranteed 1V operation - enabling direct, area-efficient integration into compact, low-power, active-high reset systems without redesign.

FAQ
What is the exact reset threshold voltage of the MAX6376XR22+?
The MAX6376XR22+ has a factory-trimmed nominal reset threshold of 2.20V, with guaranteed accuracy of ±2.5% over the full operating temperature range (-40°C to +85°C). At +25°C, the typical threshold is 2.200V, and the device maintains this specification without external calibration or trimming components.
Does the MAX6376XR22+ require any external components to operate?
No, the MAX6376XR22+ requires no external components for basic voltage monitoring operation. Its precision bandgap reference, comparator, and threshold-setting resistors are fully integrated and factory-trimmed. Only decoupling capacitance (recommended 0.1µF near VCC/GND) is advised for noise immunity - no pull-up resistors, dividers, or compensation networks are needed.
What package type and dimensions does the MAX6376XR22+ use?
The MAX6376XR22+ is supplied in a 3-pin SC70-3 package measuring 2.0mm × 2.1mm × 0.95mm. This lead-free, RoHS-compliant package is marked "ADL" on the top surface and is optimized for high-density portable PCB layouts. It is not available in SOT23-3 for this specific variant (R22 suffix).
How does the MAX6376XR22+ behave during fast VCC transients?
The MAX6376XR22+ ignores fast negative-going VCC transients up to 20µs in duration when the supply drops 100mV below threshold (i.e., to 2.10V). This built-in transient immunity prevents false resets caused by switching noise or load-step events, as confirmed by the Maximum Transient Duration vs. Threshold Overdrive graph in the datasheet.
Can the MAX6376XR22+ operate reliably below 1.8V VCC?
Yes, the MAX6376XR22+ is fully specified to operate down to 1.2V VCC and guarantees correct output logic state (high when VCC < 2.20V) even as low as 1.0V. This enables robust brownout detection in deeply discharged lithium-based batteries or during low-voltage power-up sequences where other detectors may fail silently.
