Product details
Overview
MAX6710PUT+T from Analog Devices is a quad-voltage microprocessor supervisory IC in SOT23-6 package that monitors 5.0V, 3.3V, 2.5V, and one adjustable supply (down to 0.62V) with -10% tolerance, asserts active-low open-drain RESET on any undervoltage event, and guarantees 140ms minimum reset timeout - used in servers, networking equipment, and industrial controllers for reliable power-on sequencing and brownout protection.
For engineers reviewing the MAX6710PUT+T datasheet, MAX6710PUT+T pinout, MAX6710PUT+T application, or MAX6710PUT+T equivalent, this page delivers verified threshold accuracy (±1.5%), temperature-stable hysteresis (0.3% VTH), IN2-powered operation (1.0V–5.5V), 35μA supply current, and guaranteed -40°C to +105°C performance - critical for high-reliability embedded power monitoring.
Technical Context
The MAX6710PUT+T implements four independent voltage comparators tied to an internal 0.62V bandgap reference, with factory-trimmed resistor networks for fixed thresholds (5.0V/3.3V/2.5V) and direct comparator input access for adjustable channels. Its NOR-gated reset logic ensures single-point assertion when any monitored rail falls below its threshold.
Reset timing is governed by a dedicated timeout circuit: after all inputs rise above threshold, RESET remains low for ≥140ms (typ. 200ms), independent of supply slew rate. The open-drain output features a 10μA internal pullup to IN2, eliminating external components in many 3.3V logic interfaces while maintaining valid state down to IN2 = 1.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | 5.0V (-10%), 3.3V (-10%), 2.5V (-10%), and one adjustable channel (0.62V ref, supports down to 0.62V via external divider) |
| Reset Timeout Period | 140ms minimum - ensures stable processor initialization after power recovery in servers and telecom systems |
| Supply Current | 35μA typical - enables always-on supervision in battery-backed or low-power industrial nodes |
| Input Voltage Range (IN2) | 1.0V to 5.5V - allows operation from monitored 3.3V rail without separate VCC, simplifying BOM |
| Threshold Accuracy | ±1.5% over -40°C to +105°C - eliminates need for calibration in harsh-environment applications |
| Hysteresis | 0.3% of VTH - prevents chatter during slow-rising/falling supply transients without degrading trip point precision |

Key Features
| Feature | Design Value |
|---|---|
| Quad-voltage monitoring with mixed fixed/adjustable thresholds | Supports heterogeneous supply architectures (e.g., 5V/3.3V/2.5V core + 1.2V I/O) using single IC - reduces board area vs. discrete supervisors |
| Factory-trimmed -10% thresholds for 5.0V/3.3V/2.5V rails | Eliminates external resistor selection and calibration; meets JEDEC JESD8-12B tolerance requirements for server memory rails |
| 0.62V internal reference with ±1.5% accuracy | Enables precise low-voltage monitoring (e.g., 1.8V at -10% = 1.62V) using standard 1% resistors - no trimming required |
| 140ms minimum reset timeout | Guarantees sufficient hold time for x86 and ARM processors requiring >100ms reset assertion after power stabilization |
| IN2-powered operation with 1V minimum validity | Permits direct tie to monitored 3.3V rail - removes need for auxiliary bias supply and improves fault coverage |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6710AUT+T | Same package and pinout; monitors 5.0V (-10%), 3.3V (-10%), 2.5V (-10%), and adjustable - identical electrical specs but different top mark (AAZA vs AAZP) | Valid for same server/networking designs; differs only in factory-set threshold combination (IN4 = adjustable in both) | Select MAX6710AUT+T if 5V/3.3V/2.5V/adj configuration matches design; MAX6710PUT+T uses top mark AAZP per Selector Guide |
| TPS3808G33DBVR | Triple-monitor (not quad); fixed 3.3V threshold only; no adjustable channel; 200ms timeout; higher 45μA quiescent current | Lacks fourth monitoring channel and adjustable capability - unsuitable where 1.8V or custom rail supervision is required | Use only if design needs only three rails and accepts loss of IN4 flexibility; not drop-in due to pin count and function mismatch |
Compared with MAX6710PUT+T, MAX6710AUT+T offers identical functionality with alternate factory configuration, while TPS3808G33DBVR provides shorter feature set and no quad-monitoring capability - making MAX6710PUT+T the only option supporting simultaneous 5V/3.3V/2.5V/adj supervision in SOT23-6.

FAQ
What is the exact reset timeout duration for MAX6710PUT+T?
The MAX6710PUT+T guarantees a minimum reset timeout period of 140ms after all monitored voltages rise above their thresholds, with typical value of 200ms and maximum of 280ms over temperature. This timeout is generated internally and does not depend on external components - ensuring consistent processor initialization timing in servers and telecom gear where deterministic boot sequences are mandatory.
Does MAX6710PUT+T require a separate VCC supply?
No, MAX6710PUT+T is powered directly from the IN2 pin, which monitors the 3.3V supply in this variant. The device operates with IN2 between 1.0V and 5.5V and maintains valid RESET output as long as IN2 ≥ 1.0V - eliminating need for auxiliary VCC and simplifying power architecture in 3.3V-centric systems like networking switches and industrial controllers.
How accurate are the factory-set thresholds on MAX6710PUT+T?
The factory-trimmed thresholds for 5.0V (-10%), 3.3V (-10%), and 2.5V (-10%) on MAX6710PUT+T are specified at ±1.5% over -40°C to +105°C, with typical hysteresis of 0.3% of VTH. This accuracy is achieved via laser-trimmed resistor networks and validated across temperature - meeting stringent requirements for server memory rail supervision per JEDEC standards.
Can MAX6710PUT+T monitor a 1.8V supply?
Yes, MAX6710PUT+T monitors 5.0V, 3.3V, and 2.5V with fixed thresholds, and its fourth input (IN4) is adjustable - enabling 1.8V monitoring by configuring an external resistor divider to scale 1.8V down to the internal 0.62V reference. The device's ±0.2μA input bias on adjustable pins ensures <1% error with standard 1% resistors up to 100kΩ.
What is the purpose of the 10μA internal pullup on the RESET pin of MAX6710PUT+T?
The 10μA internal pullup on MAX6710PUT+T's open-drain RESET pin connects to IN2, allowing direct interface with 3.3V logic without external components. It ensures defined high-state voltage (≥0.8×IN2) when deasserted and eliminates floating conditions - critical for noise immunity in industrial environments where external pullups may introduce EMI coupling paths.
