Product details
Overview
MAX6375XR22+T from Maxim Integrated is an ultra-low-power, active-low voltage detector in SC70-3 package with factory-trimmed 2.20V threshold, ±2.5% accuracy over temperature, 500nA supply current, and push-pull output. It monitors VCC supply voltage in portable battery-powered systems and asserts OUT low when VCC drops below threshold.
For engineers reviewing the MAX6375XR22+T datasheet, MAX6375XR22+T pinout, MAX6375XR22+T application, or MAX6375XR22+T equivalent, key selection criteria include reset threshold tolerance, supply current at 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 MAX6375XR22+T integrates a precision bandgap reference, comparator, and laser-trimmed resistive divider to set a fixed 2.20V detection threshold. Its internal architecture ensures stable operation from VCC = 1.2V to 5.5V and guarantees correct output state down to 1V.
It features built-in immunity to fast negative-going VCC transients-maximum allowable glitch duration decreases as threshold overdrive increases-and delivers propagation delay of 6.3µs (falling) with 100mV hysteresis to prevent chatter near trip point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.20V ±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 battery life in coin-cell–powered devices |
| Output Type | Active-low push-pull - drives logic-low directly without external pull-up; sinks 100µA at 0.4V VOL |
| VCC Operating Range | 1.2V to 5.5V - supports monitoring of Li+ cells, 3.3V/5V rails, and post-LDO supplies |
| Propagation Delay | 6.3µs (falling edge) - provides timely reset assertion during rapid supply collapse |
| Hysteresis | 100mV - prevents oscillation during slow or noisy VCC recovery near threshold |
| Tempco | 40ppm/°C - contributes to tight threshold stability over full temperature range |
Pinout & Package
MAX6375XR22+T is housed in a 3-pin SC70-3 package (2.0mm × 2.1mm × 0.95mm), optimized for high-density portable PCB layouts.
| 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; drives logic-low when VCC < 2.20V; no external pull-up required |
| 3 | VCC | Supply input; powers internal circuitry and defines monitored rail; operates from 1.2V to 5.5V |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB22DBZR | 2.2V threshold, 350nA ICC, SOT23-3, open-drain output | Requires external pull-up; lower ICC but incompatible logic drive without redesign | Select when lowest possible supply current is critical and system already uses open-drain reset buses |
| APX803S-22SA-7 | 2.2V threshold, 800nA ICC, SOT23-3, push-pull active-low, -40°C to +125°C rating | Higher temperature range and ICC; same pinout but wider VCC range (up to 6V) | Select for automotive under-hood or extended-temperature industrial use where 125°C operation is required |
Compared with TLV803EB22DBZR and APX803S-22SA-7, the MAX6375XR22+T offers optimal balance of ultra-low ICC (500nA), guaranteed 1V operation, and SC70-3 size-making it preferred for space- and battery-limited consumer portables where -40°C to +85°C suffices.

FAQ
What is the exact reset threshold voltage of MAX6375XR22+T and how tightly is it specified?
The MAX6375XR22+T has a 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, with min/max bounds of 2.167V and 2.233V. This tight tolerance ensures consistent brown-out behavior across production units and environmental conditions without calibration.
Does MAX6375XR22+T require any external components to operate?
No, the MAX6375XR22+T requires no external components. Its precision bandgap reference, comparator, and factory-laser-trimmed resistor network are fully integrated. The device functions with only three connections: VCC, GND, and OUT. This eliminates BOM cost, layout area, and calibration effort-making MAX6375XR22+T ideal for high-volume, space-constrained applications.
What is the minimum VCC voltage at which MAX6375XR22+T guarantees correct output logic state?
The MAX6375XR22+T guarantees correct output logic state (OUT = low when VCC < 2.20V, OUT = high otherwise) down to VCC = 1V. This is explicitly specified in the datasheet and enables reliable reset assertion even during deep battery discharge or severe brown-out conditions where other detectors may fail or behave unpredictably.
How does MAX6375XR22+T handle short voltage transients on the VCC line?
The MAX6375XR22+T incorporates inherent immunity to fast negative-going VCC transients. Its internal design filters glitches up to 200µs in duration when the overdrive (VTH – VCC) is 20mV, and shorter durations at larger overdrives. This prevents false resets caused by switching noise or load dumps-ensuring MAX6375XR22+T asserts reset only during genuine supply failures.
Is MAX6375XR22+T pin-compatible with other packages in the MAX6375–MAX6380 family?
The MAX6375XR22+T uses the SC70-3 package, while its SOT23-3 counterpart is MAX6375UR22+T. Both share identical pinout (GND, OUT, VCC) and electrical specifications, but SC70-3 has smaller footprint (2.0mm × 2.1mm vs. 2.9mm × 1.6mm) and different thermal characteristics. Layouts must be adapted for SC70-3 dimensions, though schematic symbols and net connectivity remain identical.
