Product details
Overview
MAX6710GUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC that monitors 5.0V, 3.3V, and two adjustable thresholds (down to 0.62V) with ±5% factory-trimmed accuracy, asserting a single active-low open-drain RESET output when any supply falls below its threshold - used in server power sequencing and industrial control systems requiring reliable multi-rail monitoring.
For engineers reviewing the MAX6710GUT+T datasheet, MAX6710GUT+T pinout, MAX6710GUT+T application, or MAX6710GUT+T equivalent, this device delivers deterministic 140ms min reset timeout, 35μA quiescent current, and guaranteed operation from −40°C to +105°C in a space-constrained SOT23-6 footprint.
Technical Context
The MAX6710GUT+T implements four independent voltage comparators with a shared 0.62V internal reference and precision resistor-divider networks for fixed thresholds (5.0V/3.3V), while two inputs accept external resistor dividers for adjustable monitoring. Its NOR-gated reset logic ensures assertion on any undervoltage event.
It features built-in 0.3% threshold hysteresis, immunity to ≤100µs input transients per typical characterization, and RESET validity maintained as long as IN1 or IN2 ≥ 1.0V - enabling robust operation during brown-out recovery without external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | 5.0V (−10%), 3.3V (−10%), two adjustable down to 0.62V - supports mixed-rail systems with no external components for fixed thresholds |
| Reset Timeout | 140ms minimum after all supplies recover - ensures full processor initialization before release |
| Supply Current | 35μA typical - enables always-on monitoring in battery-backed or low-power industrial nodes |
| Operating Temp | −40°C to +105°C - qualified for extended-temperature industrial and telecom equipment |
| Input Hysteresis | 0.3% of VTH - prevents chatter during slow-rising/falling supply edges |
| RESET Output | Open-drain with 10μA internal pullup to IN2 - eliminates need for external pullup in 3.3V logic domains |
| Threshold Accuracy | ±1.5% for adjustable inputs, ±2.5% for factory-trimmed 5.0V/3.3V - meets JEDEC JESD8-12A for system-level reset integrity |
Pinout & Package
Package: 6-pin SOT23-6, 1.6mm × 2.9mm × 1.1mm body, RoHS-compliant, tape-and-reel packaging (2500-piece minimum).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Fixed-threshold input | Monitors 5.0V supply at −10% threshold (4.50V min); referenced to internal bandgap |
| 2 - IN2 | Power supply & monitor input | Primary power source (3.3V) and monitored rail; RESET valid if ≥1.0V |
| 3 - IN3 | Adjustable-threshold input | 0.62V internal comparator reference; external resistor divider sets custom threshold |
| 4 - IN4 | Adjustable-threshold input | Second 0.62V-referenced input; supports dual auxiliary rail monitoring (e.g., 1.2V, 1.0V) |
| 5 - GND | Analog/digital ground | Common return for all comparators and RESET driver; requires low-impedance PCB connection |
| 6 - RESET | Active-low open-drain output | Asserts low on any undervoltage; pulls high via internal 10μA current source to IN2 |
Key Features
| Feature | Design Value |
|---|---|
| Quad-voltage monitoring | Simultaneously supervises four independent rails - reduces BOM count vs. discrete supervisors |
| Factory-trimmed thresholds | Guaranteed 5.0V/−10% and 3.3V/−10% detection without calibration - accelerates design validation |
| Adjustable inputs (2) | Supports monitoring of sub-1V rails (e.g., core voltages) using standard 1% resistors - no trimming required |
| Glitch-immune architecture | Rejects transients ≤100µs duration - prevents false resets during switching noise or load dumps |
| Extended temperature range | Full specification over −40°C to +105°C - suitable for uncooled industrial enclosures and base station gear |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710HUT+T | Same package and pinout; 5.0V/−5% and 3.3V/−5% fixed thresholds instead of −10% | Better suited for systems requiring tighter tolerance on primary rails (e.g., PCIe-compliant platforms) | Select when 4.75V min 5V rail detection is required instead of 4.50V |
| TPS3808G33DBVR | Triple-monitor only; 3.3V fixed threshold + two adjustable; 200ms timeout; 16μA ICC | Lacks fourth monitor channel; lower quiescent current but no 5V rail support | Choose for cost-sensitive 3-rail designs where 5V supervision is handled separately |
Compared with MAX6710HUT+T, the MAX6710GUT+T provides looser 5V/3.3V thresholds ideal for legacy or margin-tolerant systems; versus TPS3808G33DBVR, it adds critical fourth-rail coverage at the expense of 19μA higher ICC - a trade-off justified in complex multi-processor embedded systems.

FAQ
What is the exact reset timeout duration specified for MAX6710GUT+T?
The MAX6710GUT+T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their respective thresholds. Typical timeout is 200ms, with a maximum of 280ms over temperature. This fixed delay ensures sufficient time for microprocessors and FPGAs to complete internal initialization before release - a key requirement in server and telecom applications where MAX6710GUT+T is deployed.
Does MAX6710GUT+T support manual reset functionality?
Yes, the MAX6710GUT+T supports manual reset via its adjustable inputs (IN3 or IN4). As documented in Figure 6 of the datasheet, connecting a pushbutton switch between an adjustable input and ground initiates a reset pulse. The switch must remain open for at least 140ms to deassert RESET. No external debounce circuitry is needed, making MAX6710GUT+T suitable for field-serviceable industrial equipment requiring operator-initiated reboots.
What are the absolute maximum voltage ratings for the IN1 and IN2 pins of MAX6710GUT+T?
The absolute maximum rating for IN1 and IN2 pins of MAX6710GUT+T is −0.3V to +6V relative to GND. However, normal operating range for IN2 (which also powers the device) is 1.0V to 5.5V over temperature, and for IN1 (5.0V fixed threshold) it is specified up to 5.5V. Exceeding these limits risks latch-up or permanent damage - a critical constraint when integrating MAX6710GUT+T into systems with transient-prone power rails.
Can MAX6710GUT+T monitor a 1.2V supply, and how is the threshold set?
Yes, MAX6710GUT+T can monitor a 1.2V supply using either IN3 or IN4, both of which feature a 0.62V internal comparator reference. To monitor 1.2V, connect an external resistor divider such that VINx = 0.62V × (R1 + R2)/R2. For example, with R2 = 100kΩ, R1 ≈ 93.5kΩ yields ~1.2V threshold. Input bias current is ≤0.2μA, ensuring <1% error - a capability confirmed in the MAX6710GUT+T selector guide and electrical characteristics table.
Is the RESET output of MAX6710GUT+T compatible with 5V logic systems?
Yes, the open-drain RESET output of MAX6710GUT+T is compatible with 5V logic systems. While its internal 10μA pullup connects to IN2 (typically 3.3V), an external pullup resistor to 5V can safely overdrive it - internal circuitry prevents reverse current flow into IN2. This allows MAX6710GUT+T to drive 5V microcontrollers or CPLDs without level-shifting, as explicitly validated in Figure 4 of the MAX6710GUT+T datasheet.
