Product details
Overview
MAX6806UR23-T from Maxim Integrated is a precision voltage detector IC designed for power-supply monitoring in microprocessor-based systems. It features a factory-preset 2.3V ±2% reset threshold, active-low push-pull RESET output, and guaranteed operation down to VCC = 1.0V - enabling reliable brownout detection in battery-powered embedded controllers and portable instrumentation.
For engineers reviewing the MAX6806UR23-T datasheet, MAX6806UR23-T pinout, MAX6806UR23-T application, or MAX6806UR23-T equivalent, key selection criteria include its 2.3V threshold accuracy, 35µA supply current, SOT23-3 package compatibility, and immunity to sub-100µs negative VCC transients in critical µP power monitoring.
Technical Context
The MAX6806UR23-T implements a precision bandgap-based voltage comparator with internal hysteresis (VHYST = 0.02–0.03 × VTH−), ensuring stable reset assertion/deassertion during supply ramp-up and brownout conditions. Its push-pull output drives CMOS logic directly without external pullup components.
It operates across −40°C to +85°C with supply voltage range 1.0V to 5.5V, and features no external component requirements - eliminating trimming resistors or capacitors typically needed in discrete reset circuits. The device asserts RESET when VCC falls below 2.254V (min) and releases it only after VCC rises above 2.346V (max), per ±2% threshold tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.30V ±2% (2.254V–2.346V at +25°C); ensures accurate power-fail detection for 2.5V/3.3V systems operating near minimum supply limits |
| Supply Current | 35µA typical at VCC = 3.6V; enables ultra-low-power operation in battery-backed or energy-constrained applications |
| RESET Valid Down To | VCC = 1.0V; guarantees logic-low output even during deep brownout, supporting fail-safe shutdown before system lockup |
| Output Type | Active-low push-pull; eliminates need for external pullup resistor and supports direct interface to µP reset inputs |
| Hysteresis | 0.02–0.03 × VTH− (≈46–69mV); prevents output chatter during slow or noisy supply transitions near threshold |
| Operating Temp Range | −40°C to +85°C; qualified for industrial and portable equipment environments without derating |
| VCC Transient Immunity | Immune to negative-going VCC transients ≤100µs (at 100mV overdrive); suppresses false resets from switching noise or ESD coupling |
Pinout & Package
MAX6806UR23-T is housed in a 3-pin SOT23 package (JEDEC MO-178AA), with 1.3mm × 2.9mm footprint and 0.95mm height - optimized for space-constrained PCB layouts in portable electronics.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET (active-low) | Push-pull output asserted low when VCC < 2.3V; sinks up to 1mA at VCC = 2.0V; valid down to VCC = 1.0V |
| 2 | GND | Ground reference for internal comparator and output stage; must be connected to system ground plane |
| 3 | VCC | Supply input; accepts 1.0V–5.5V; internal circuitry remains functional and RESET valid across full range |
Key Features
| Feature | Design Value |
|---|---|
| ±2% threshold accuracy | Guarantees reset assertion before downstream ICs (e.g., µCs rated for 2.5V ±10%) drop out of spec |
| No external components | Eliminates BOM cost and layout area for trimming resistors, capacitors, or pullups - reduces design cycle time |
| 35µA quiescent current | Extends battery life in always-on monitoring applications such as barcode scanners and handheld instruments |
| 1.0V minimum VCC operation | Enables full reset functionality during deep discharge states where other detectors lose output drive capability |
| Transient immunity | Rejects short-duration VCC dips (≤100µs) caused by digital switching or EMI, preventing spurious system resets |
Applications
| Portable/Battery-Powered Equipment | Intelligent Instruments |
|---|---|
|
Use Scenario: Power monitoring in handheld multimeters and portable data loggers with Li-ion or alkaline battery supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB23DBZR | 2.3V ±1% threshold; 0.5µA max ICC; open-drain output; requires external pullup | Lower power but needs pullup resistor; not push-pull - unsuitable for direct µP reset without level-shifting | Select when ultra-low ICC (<1µA) is mandatory and board space allows pullup; avoid if direct push-pull drive is required. |
| ADM6706SARZ-23 | 2.32V ±1.5% threshold; 15µA ICC; push-pull output; includes watchdog timer and manual reset | Higher integration (watchdog + MR) increases cost and complexity; overkill for pure voltage monitoring | Choose only if watchdog or manual reset functionality is needed; otherwise MAX6806UR23-T offers lower cost and simpler BOM. |
Compared with TLV803EB23DBZR and ADM6706SARZ-23, the MAX6806UR23-T delivers optimal balance of precision (±2%), ultra-low ICC (35µA), and true push-pull drive - making it ideal for cost-sensitive, space-constrained µP reset applications without added features.

FAQ
What is the exact reset threshold voltage of the MAX6806UR23-T?
The MAX6806UR23-T has a factory-trimmed nominal reset threshold of 2.30V with ±2% accuracy over temperature, meaning the actual threshold falls between 2.254V (min) and 2.346V (max) at +25°C. This value is guaranteed across −40°C to +85°C per the datasheet's electrical characteristics table, and applies specifically to the falling VCC condition (VTH−).
Does the MAX6806UR23-T require any external components to operate?
No, the MAX6806UR23-T requires no external components - it integrates the voltage reference, comparator, hysteresis, and push-pull output driver in a single die. Unlike discrete solutions or older supervisors, it needs only VCC, GND, and the RESET load (e.g., µP reset pin); no pullup resistors, timing capacitors, or trimming networks are necessary for basic operation.
Can the MAX6806UR23-T drive a standard microprocessor reset input directly?
Yes, the MAX6806UR23-T features an active-low push-pull RESET output capable of sinking ≥1mA at VCC = 2.0V and sourcing sufficient current to drive typical CMOS µP reset inputs without external buffering. Its output remains valid down to VCC = 1.0V, ensuring reliable assertion even during deep brownout - unlike open-drain alternatives that require pullup resistors.
What is the supply current consumption of the MAX6806UR23-T?
The MAX6806UR23-T draws 35µA typical supply current at VCC = 3.6V and 50–80µA maximum at VCC = 5.5V, as specified in the Electrical Characteristics table. This ultra-low ICC enables multi-year battery life in always-on monitoring applications such as portable instrumentation and handheld scanners - confirmed across the full −40°C to +85°C operating range.
Is the MAX6806UR23-T compatible with noisy power rails?
Yes, the MAX6806UR23-T is explicitly designed to reject short-duration negative-going VCC transients - it remains immune to pulses ≤100µs wide when the overdrive (VTH− − VCC) is ≤100mV. This immunity, combined with internal hysteresis, prevents false resets caused by switching noise, ESD coupling, or inductive kickback on shared power rails.
