Product details
Overview
MAX6806XR23+T from Maxim Integrated is a precision voltage detector IC designed for reliable 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 robust brownout detection in battery-powered instrumentation and portable controllers.
For engineers reviewing the MAX6806XR23+T datasheet, MAX6806XR23+T pinout, MAX6806XR23+T application, or MAX6806XR23+T equivalent, key selection considerations include its SC70-3 package footprint, 35µA quiescent current, hysteresis-enabled noise immunity, and compatibility with low-voltage µP reset interfaces requiring valid logic levels below 1.8V.
Technical Context
The MAX6806XR23+T implements a precision bandgap-based voltage comparator with internal hysteresis (VHYST = 0.02–0.03 × VTH−), ensuring stable reset assertion/deassertion during supply transients. Its push-pull output drives CMOS inputs directly without external pull-up components.
It operates across −40°C to +85°C with supply voltage range 1.0V to 5.5V, and features a manual-reset–capable variant only in SOT143 - not applicable to this SC70-3 version. The device asserts RESET when VCC falls below 2.254V (min) and releases it when VCC rises above 2.346V (max), per ±2% threshold accuracy at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.30V ±2% (2.254V–2.346V at +25°C); ensures reliable detection of 2.5V supply droop before system ICs fail. |
| Supply Current | 35µA typical at VCC = 3.6V; enables multi-year battery life in portable equipment. |
| RESET Valid Down To | VCC = 1.0V; guarantees clean reset assertion even during deep brownout or partial power collapse. |
| Hysteresis | 0.02–0.03 × VTH−; prevents output chatter near threshold during slow-rising/falling supplies. |
| Output Type | Active-low push-pull; eliminates need for external pull-up resistor and supports direct CMOS interface. |
| Operating Temp | −40°C to +85°C; qualified for industrial and extended-temperature embedded applications. |
| Package | 3-pin SC70 (X3-2 outline); 1.25mm × 0.85mm footprint ideal for space-constrained portable designs. |
Pinout & Package
MAX6806XR23+T is housed in a 3-pin SC70 package (outline X3-2), with pin 1 = RESET (active-low push-pull), pin 2 = GND, and pin 3 = VCC. No manual reset (MR) input is present - that function is exclusive to the 4-pin SOT143 variant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-low push-pull output; sinks current when asserted, sources current when deasserted - no external pull-up required. |
| 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; powers internal circuitry and drives RESET output high-level voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.3V Threshold | ±2% accuracy over temperature ensures consistent reset timing across −40°C to +85°C without calibration. |
| Ultra-Low ICC | 35µA typical supply current minimizes loading on weak or battery-backed supplies. |
| Push-Pull Output | Eliminates external pull-up resistor, reduces BOM count, and guarantees defined logic levels at all VCC ≥ 1.0V. |
| Transient Immunity | Immune to negative-going VCC transients ≤100µs (at 100mV overdrive), improving reliability in noisy power environments. |
| SC70-3 Footprint | 1.25mm × 0.85mm package enables high-density layout in handheld and IoT sensor nodes. |
Applications
| Portable Medical Instrumentation | Industrial Controller Power Monitoring |
|---|---|
|
Use Scenario: Battery-powered handheld blood glucose meters require reliable reset during Li-ion discharge from 3.6V to 2.2V. IC Role / Device Role / Timing Role: Voltage detector asserting RESET when supply crosses 2.3V threshold to prevent firmware corruption. Use Value: Guaranteed 2.3V ±2% trip point ensures reset occurs before MCU enters undefined state, preserving data integrity. |
Use Scenario: PLC I/O modules powered from isolated 3.3V rails must detect undervoltage before fieldbus communication fails. IC Role / Device Role / Timing Role: Primary supervisor IC generating clean, fast reset pulse (<30µs delay) upon rail collapse. Use Value: 35µA quiescent current avoids loading sensitive isolated supplies; push-pull output drives optocoupler inputs directly. |
| Barcode Scanner Logic Supervision | Smart Sensor Node Power Management |
|
Use Scenario: USB-powered barcode scanners experience rapid VBUS drop during cable disconnect; must reset cleanly before re-enumeration. IC Role / Device Role / Timing Role: Reset generator with fast response (<30µs) to falling VCC, synchronized to USB enumeration timing. Use Value: Valid RESET down to VCC = 1.0V ensures reset remains asserted through full VBUS decay, preventing partial initialization. |
Use Scenario: LoRaWAN end-node sensors operate intermittently on coin-cell batteries; supply may sag to 2.1V during RF transmit bursts. IC Role / Device Role / Timing Role: Low-power supervisor detecting 2.3V threshold violation to trigger graceful shutdown or sleep-state recovery. Use Value: SC70-3 size fits sub-10mm² PCB area; ±2% threshold accuracy avoids false resets during normal load transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB23DBZR | 2.32V threshold, ±1% accuracy, SOT23-3, 300nA ICC, open-drain output | Requires external pull-up; lower ICC but no push-pull drive capability | Select when ultra-low power dominates over output drive strength and board space allows pull-up resistor |
| TPS3808G23DBVR | 2.3V threshold, ±0.5% accuracy, SOT23-6, 8µA ICC, active-low push-pull, programmable delay | Larger package, includes adjustable reset timeout; higher cost and complexity | Select when reset timeout functionality is required to avoid premature release during supply recovery |
Compared with TLV803EB23DBZR and TPS3808G23DBVR, the MAX6806XR23+T offers optimal balance of precision (±2%), ultra-low ICC (35µA), push-pull output, and minimal SC70-3 footprint - making it ideal for cost- and space-sensitive portable systems where fixed-delay reset is sufficient.

FAQ
What is the exact reset threshold voltage of the MAX6806XR23+T?
The MAX6806XR23+T has a factory-trimmed nominal reset threshold of 2.30V with ±2% accuracy over temperature, meaning the actual threshold falls between 2.254V and 2.346V at +25°C. This value is guaranteed across the full −40°C to +85°C operating range, with a tempco of ≤30ppm/°C.
Does the MAX6806XR23+T support manual reset functionality?
No, the MAX6806XR23+T does not support manual reset. Manual reset (MR) is only available on the 4-pin SOT143 package variants (e.g., MAX6806US23-T). The MAX6806XR23+T uses a 3-pin SC70 package with RESET, GND, and VCC pins only - no MR terminal is present or internally connected.
What is the minimum supply voltage at which the MAX6806XR23+T guarantees valid RESET output?
The MAX6806XR23+T guarantees valid RESET output down to VCC = 1.0V. Specifically, the RESET pin is guaranteed to sink ≥20µA while asserted (low) and maintain VOL ≤ 0.3V at VCC = 1.0V, ensuring interoperability with low-voltage logic families during deep brownout conditions.
Can the MAX6806XR23+T be used with a 1.8V supply rail?
Yes, the MAX6806XR23+T operates fully within specification on a 1.8V supply: its supply voltage range is 1.0V to 5.5V, and its 2.3V reset threshold remains accurate and functional. At VCC = 1.8V, RESET will assert low whenever the rail drops below ~2.25V - a condition indicating imminent failure of downstream 1.8V logic, making it suitable for early-warning supervision.
What package type and footprint does the MAX6806XR23+T use?
The MAX6806XR23+T uses a 3-pin SC70 package (outline X3-2), measuring 1.25mm × 0.85mm with 0.65mm lead pitch. Its land pattern matches standard SC70-3 footprints (e.g., Maxim's land pattern no. 90-0208), and it is supplied in tape-and-reel format with a 2500-piece minimum order quantity.
