Product details
Overview
MAX6710HUT+T from Analog Devices is a precision quad-voltage microprocessor supervisory IC that monitors 5.0V, 3.3V, and two adjustable inputs (down to 0.62V) and asserts a single active-low open-drain RESET output when any supply falls below its threshold. It provides 140ms minimum reset timeout, -40°C to +105°C operation, and 35μA supply current - used in servers, networking equipment, and industrial controllers for reliable power-on reset and brownout detection.
For engineers reviewing the MAX6710HUT+T datasheet, MAX6710HUT+T pinout, MAX6710HUT+T application, or MAX6710HUT+T equivalent, key selection considerations include factory-trimmed 5V/3.3V thresholds with ±5% tolerance, dual adjustable monitoring capability, SOT23-6 package constraints, and guaranteed reset validity down to IN1 = 1V or IN2 = 1V.
Technical Context
The MAX6710HUT+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) and direct comparator inputs for adjustable channels. Its NOR-gated reset logic ensures assertion if any input drops below its threshold.
It features built-in 0.3% threshold hysteresis, immunity to ≤100µs supply transients, and a weak 10µA internal pullup to IN2 on the open-drain RESET pin. Reset remains asserted for ≥140ms after all monitored voltages recover, meeting JEDEC JESD84-B51 requirements for processor reset timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | 5.0V (-5%), 3.3V (-5%), two adjustable inputs (0.62V reference, supports monitoring down to 0.62V via external divider) |
| Reset Timeout Period | 140ms minimum - ensures stable processor initialization after power recovery in server and telecom systems |
| Supply Current | 35μA typical - enables use in always-on, low-power subsystems without impacting system budget |
| Operating Temperature | -40°C to +105°C - qualified for industrial and extended-temperature embedded applications |
| Input Voltage Range (IN1/IN3/IN4) | 0.611V to 0.629V threshold accuracy (±1.5%) - enables precise undervoltage detection for sub-1V rails |
| RESET Output Type | Open-drain with 10μA internal pullup to IN2 - eliminates need for external pullup in many 3.3V logic interfaces |
| Reset Validity Condition | RESET remains valid as long as IN1 ≥ 1V or IN2 ≥ 1V - supports partial power-up sequencing in multi-rail systems |
Pinout & Package
MAX6710HUT+T is housed in a 6-pin SOT23-6 package (JEDEC MO-178AA), footprint-compatible with industry-standard 2.9mm × 1.6mm layouts and reflow-solderable per IPC/JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN1 | Fixed 5.0V (-5%) monitor input - connects to main 5V rail; threshold = 4.50V min |
| 2 | IN2 | Fixed 3.3V (-5%) monitor input and primary power supply - powers device; threshold = 3.00V min |
| 3 | IN3 | Adjustable monitor input - referenced to 0.62V internal comparator; requires external resistor divider for >0.62V rails |
| 4 | IN4 | Adjustable monitor input - identical function to IN3; supports independent monitoring of second auxiliary rail |
| 5 | GND | Analog ground reference - must be connected to system power ground plane for accurate threshold sensing |
| 6 | RESET | Active-low open-drain reset output - sinks up to 2mA; pulled up internally to IN2 (10μA); asserts when any IN_ falls below threshold |
Key Features
| Feature | Design Value |
|---|---|
| Quad-supply monitoring with mixed fixed/adjustable thresholds | Supports simultaneous validation of legacy 5V/3.3V rails plus two modern low-voltage rails (e.g., 1.2V, 0.9V) using same IC |
| Factory-trimmed ±5% threshold accuracy | Eliminates external calibration for 5.0V and 3.3V rails - reduces BOM count and improves production yield |
| 140ms minimum reset timeout | Meets Intel VRD/IMVP and AMD PSP boot timing requirements without external RC timing components |
| 0.3% threshold hysteresis | Prevents chatter during marginal supply conditions - critical for noisy industrial power environments |
| Immunity to ≤100µs supply transients | Rejects ESD-induced glitches and switching noise without false resets - verified per Typical Operating Characteristics graph |
Applications
| Telecom Line Cards | Industrial PLC Controllers |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710GUT+T | Same package and pinout; fixed 5V/3.3V thresholds but with -10% tolerance (4.25V/2.85V min) instead of -5% | Suitable where looser supply margin is acceptable (e.g., non-critical auxiliary rails) | Select MAX6710GUT+T only if system tolerances permit lower trip points; MAX6710HUT+T preferred for tighter 5V/3.3V specs. |
| TPS3808G33DBVR | Triple-monitor (not quad); fixed 3.3V threshold only; no adjustable inputs; 200ms timeout; 1.8V–6.5V VCC range | Lacks dual adjustable monitoring - requires additional supervisor or discrete solution for fourth rail | Choose TPS3808G33DBVR only when monitoring three rails suffices and TI ecosystem integration is prioritized. |
Compared with MAX6710GUT+T and TPS3808G33DBVR, the MAX6710HUT+T uniquely delivers quad monitoring with precisely matched -5% 5V/3.3V thresholds plus two flexible adjustable inputs - eliminating component count while maintaining full system visibility across four independent power domains.

FAQ
What is the exact reset timeout duration for MAX6710HUT+T?
The MAX6710HUT+T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their thresholds. Typical duration is 200ms, with a maximum of 280ms over temperature. This timing is internally generated and requires no external components - a key differentiator from adjustable-reset supervisors.
Does MAX6710HUT+T support monitoring a 1.2V supply?
Yes, MAX6710HUT+T supports monitoring a 1.2V supply using either IN3 or IN4 adjustable inputs. With the internal 0.62V reference, a resistor divider (e.g., R1 = 93.5kΩ, R2 = 100kΩ) sets the trip point precisely at 1.2V ±1.5%, validated across -40°C to +105°C.
Can MAX6710HUT+T operate with IN2 below 3.3V?
Yes, MAX6710HUT+T operates with IN2 as low as 1.0V (at 0°C to +105°C) or 1.2V (at -40°C to +105°C). The RESET output remains valid as long as IN2 ≥ 1V, and the device draws only 35μA - enabling use in ultra-low-voltage backup power paths.
Is an external pullup resistor required for MAX6710HUT+T's RESET pin?
No external pullup is required for MAX6710HUT+T's RESET pin in 3.3V systems, as it includes a 10μA internal pullup to IN2. For interfacing with 5V or 1.8V logic, an external pullup may be added - internal circuitry prevents reverse current flow into IN2.
How does MAX6710HUT+T handle short voltage transients on monitored inputs?
MAX6710HUT+T rejects transients ≤100µs in duration, as confirmed in the Typical Operating Characteristics plot "Maximum IN_ Transient Duration vs. Reset Threshold Overdrive." This immunity prevents false resets caused by switching noise or ESD events without compromising response to sustained brownouts.
