Product details
Overview
MAX6375UR22+ from Maxim Integrated is an ultra-low-power, active-low voltage detector IC with factory-trimmed 2.20V threshold, push-pull output, and SOT23-3 package. It monitors VCC supply voltage and asserts logic-low OUT when VCC drops below 2.20V ±2.5% over temperature, consuming only 500nA typical supply current. It operates from 1.2V to 5.5V VCC and is used in battery-powered microcontroller reset supervision.
For engineers reviewing the MAX6375UR22+ datasheet, MAX6375UR22+ pinout, MAX6375UR22+ application, or MAX6375UR22+ equivalent, key selection criteria include its 2.20V trip point, 500nA quiescent current, -40°C to +85°C operating range, push-pull active-low output configuration, and SOT23-3 footprint compatibility with space-constrained portable designs.
Technical Context
The MAX6375UR22+ integrates a precision bandgap reference, comparator, and laser-trimmed resistive divider to deliver fixed 2.20V detection without external components. Its internal architecture ensures stable operation down to 1V VCC while ignoring transients shorter than ~20µs at 20mV overdrive.
This device belongs to the MAX6375–MAX6380 family of single-function voltage detectors differentiated by threshold voltage and output type. The MAX6375UR22+ uses push-pull active-low output (OUT low when VCC < VTH), supports 1.2V–5.5V VCC range, and guarantees correct logic state across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Threshold Voltage | 2.20V ±2.5% over -40°C to +85°C - sets precise brown-out detection point for 2.2V nominal systems |
| Supply Current | 500nA typical - 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 - functions during deep brown-out and supports wide-input power rails |
| Propagation Delay | 6.3µs typical (falling edge) - provides fast response to supply collapse while rejecting sub-µs noise |
| Threshold Hysteresis | 100mV - prevents output oscillation near trip point during slow VCC recovery |

FAQ
What is the exact threshold voltage and tolerance of the MAX6375UR22+?
The MAX6375UR22+ has a nominal threshold voltage of 2.20V with ±2.5% accuracy over the full -40°C to +85°C operating temperature range. At +25°C, the typical threshold is 2.200V, with min/max limits of 2.167V/2.233V (room temperature) and 2.145V/2.250V (over temperature). This specification is factory-laser-trimmed and does not require external calibration.
Does the MAX6375UR22+ require any external components to operate?
No, the MAX6375UR22+ requires zero external components. Its precision bandgap reference, comparator, and trimmed resistor divider are fully integrated. Unlike adjustable supervisors, it needs only VCC, GND, and the OUT signal connection-no external resistors, capacitors, or pull-ups are necessary for basic voltage detection functionality.
What is the output configuration of the MAX6375UR22+ and how does it interface with a microcontroller?
The MAX6375UR22+ features an active-low push-pull output. When VCC drops below 2.20V, OUT drives logic-low (≤0.4V at 100µA sink); otherwise, OUT drives logic-high (≥0.8×VCC). It interfaces directly to standard CMOS reset inputs without external pull-up resistors, simplifying PCB layout and reducing component count compared to open-drain alternatives.
Can the MAX6375UR22+ operate reliably at very low supply voltages?
Yes, the MAX6375UR22+ is guaranteed to maintain correct output logic state down to VCC = 1.0V, and its internal circuitry remains functional across 1.2V–5.5V. This allows it to assert reset even during deep brown-out events where other supervisors may fail, making it suitable for applications powered by depleting batteries or unstable energy harvesters.
How does the MAX6375UR22+ handle power supply transients?
The MAX6375UR22+ incorporates built-in transient immunity: it ignores negative-going VCC glitches shorter than ~20µs when the overdrive (VTH – VCC) is 20mV. This rejection is characterized across temperature and eliminates need for external RC filters in noisy environments such as those with switching regulators or motor drivers.
