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% 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 - used for precision brownout detection in Li+-powered microcontroller reset circuits.
For engineers reviewing the MAX6375XR22-T datasheet, MAX6375XR22-T pinout, MAX6375XR22-T application, or MAX6375XR22-T equivalent, key selection criteria include its 2.20V trip point, SC70-3 footprint compatibility, guaranteed logic state down to 1V VCC, immunity to sub-20µs transients, and absence of external components.
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 across -40°C to +85°C with ±2.5% accuracy and 40ppm/°C tempco.
This device implements a single-function power-supply monitor: it asserts an active-low push-pull output (OUT) only when VCC falls below 2.20V, and holds valid logic state down to 1V VCC. It rejects fast negative-going transients ≤20µs at 100mV overdrive, per typical operating characteristics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Threshold Voltage | 2.20V nominal, ±2.5% over -40°C to +85°C - enables precise brownout detection for 2.4V–2.8V Li+ battery discharge endpoints. |
| Supply Current | 500nA typical - extends battery life in always-on monitoring applications such as wearable sensors and IoT edge nodes. |
| Output Type | Active-low push-pull - drives logic inputs directly without pull-up resistor; sinks 100µA at 0.4V VOL (VCC ≥1.2V). |
| Propagation Delay | 20µs max (falling edge) - provides deterministic response timing for MCU reset assertion under undervoltage conditions. |
| VCC Operating Range | 1.2V to 5.5V - supports operation during deep brownout and compatibility with 1.8V/3.3V/5V system rails. |
| Hysteresis | 100mV - prevents output chatter near threshold during slow VCC recovery or noise. |
| Package | SC70-3 (1.25mm × 2.0mm × 0.95mm) - space-constrained PCB layout for compact portable electronics. |
Pinout & Package
MAX6375XR22-T is housed in a 3-pin SC70 package (1.25mm × 2.0mm × 0.95mm body, 0.65mm pitch). Pin 1 = GND, Pin 2 = OUT, Pin 3 = VCC. Top marking "ADH" identifies this specific 2.20V variant.
| 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 MCU /RESET pin directly; 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
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 500nA enables >10-year battery life in coin-cell–powered devices monitoring VCC continuously. |
| Factory-trimmed threshold | 2.20V ±2.5% eliminates calibration effort and reduces BOM count versus discrete resistor-divider solutions. |
| Transient immunity | Rejects VCC glitches <20µs duration (at 100mV overdrive), preventing false resets in noisy power environments. |
| No external components | Self-contained detection circuit - no resistors, capacitors, or trimming required for basic brownout function. |
| Guaranteed logic state down to 1V | Ensures predictable reset behavior even during severe battery sag or cold-temperature discharge. |
Applications
| Precision Battery Monitoring | Load Switching / Power Sequencing |

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 package, open-drain output. | Requires external pull-up; not pin-compatible due to different output structure and pin 2 function. | Select when lower 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 output, -40°C to +125°C rating. | Wider temperature range but higher ICC; same pinout as MAX6375XR22-T except GND/OUT swapped (pin 1 = OUT, pin 2 = GND). | Select for automotive-adjacent industrial use where extended temperature tolerance outweighs 1.6× higher ICC. |
Compared with TLV803EB22DBZR and APX803S-22SA-7, the MAX6375XR22-T offers optimal balance of ultra-low ICC (500nA), SC70-3 size, and push-pull simplicity - ideal for space- and energy-constrained consumer portables where pinout and footprint match existing designs.

FAQ
What is the exact threshold voltage and tolerance of the MAX6375XR22-T?
The MAX6375XR22-T has a factory-trimmed nominal threshold voltage of 2.20V, with guaranteed accuracy of ±2.5% over the full operating temperature range (-40°C to +85°C). This specification is confirmed in the Electrical Characteristics table and applies to all units shipped as MAX6375XR22-T, not just typical samples.
Does the MAX6375XR22-T require any external components to operate?
No, the MAX6375XR22-T requires no external components. Its precision bandgap reference, comparator, and laser-trimmed resistor network are fully integrated. Only VCC, GND, and the load on the OUT pin (e.g., a microcontroller /RESET input) are needed - eliminating calibration, BOM items, and layout area.
What is the output configuration of the MAX6375XR22-T, and how does it interface with a microcontroller?
The MAX6375XR22-T features an active-low push-pull output. When VCC drops below 2.20V, OUT is driven low (≤0.4V at 100µA sink); otherwise, OUT is driven high (≥0.8×VCC). It connects directly to standard CMOS /RESET inputs without pull-up resistors - simplifying interface and reducing power loss.
Can the MAX6375XR22-T operate reliably at very low supply voltages?
Yes, the MAX6375XR22-T guarantees correct output logic state down to VCC = 1V, enabling reliable brownout detection even during deep battery discharge. Its internal circuitry remains functional and deterministic below 1.2V - a key advantage over many competing detectors that cease operation near 1.5V.
What package type and markings identify the MAX6375XR22-T?
The MAX6375XR22-T is supplied exclusively in the SC70-3 package (1.25mm × 2.0mm × 0.95mm) with top-side marking "ADH". This marking is unique to the R22 (2.20V) variant in SC70 packaging and is verified in Maxim's official Selector Guide and Marking Code tables.
