Product details
Overview
MAX6710PUT from Maxim Integrated is a precision quad-voltage microprocessor supervisory circuit that monitors four independent supply rails-including one 3.0V monitored input (IN2), one 1.8V monitored input (IN3), and two adjustable-threshold inputs (IN1, IN4) set via external resistor dividers-and asserts a single active-low open-drain RESET output if any falls below its threshold. It operates from -40°C to +85°C with 140ms minimum reset timeout and 35µA supply current, used in telecom power sequencing and industrial embedded systems.
For engineers reviewing the MAX6710PUT datasheet, MAX6710PUT pinout, MAX6710PUT application, or MAX6710PUT equivalent, this page delivers verified specifications, SOT23-6 terminal mapping, factory-trimmed and adjustable threshold behavior, reset timing constraints, and real-world supervisory use cases-enabling rapid validation for multi-rail voltage monitoring in space-constrained designs.
Technical Context
The MAX6710PUT uses an internal 0.62V bandgap reference and four precision comparators with 0.3% threshold hysteresis to detect undervoltage conditions across its four inputs. Its power is derived solely from IN2 (3.0V), eliminating need for separate VCC; RESET remains valid as long as IN1 or IN2 >1V.
Adjustable inputs (IN1, IN4) accept external resistor dividers to monitor voltages down to 0.62V with ±1.5% accuracy; fixed thresholds for IN2 (3.0V ±5%) and IN3 (1.8V ±5%) are factory-trimmed. The device ignores transients <100µs at typical overdrive levels, confirmed by glitch immunity characterization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | IN2 = 1.2V to 5.5V - powers device and defines operating window; RESET valid down to IN2 = 1V |
| Fixed Thresholds | IN2 = 3.0V ±5%, IN3 = 1.8V ±5% - factory-trimmed, no external components needed |
| Adjustable Threshold | IN1/IN4 = 0.62V ±1.5% - enables monitoring of any rail ≥0.62V using external R-divider |
| Reset Timeout Period | 140ms (min) - ensures reliable µP reset hold time after all supplies stabilize |
| Supply Current | 35µA (typ) - ultra-low quiescent current supports battery-backed or low-power systems |
| Input Hysteresis | 0.3% of VTH - prevents chatter during slow-moving or noisy supply transitions |
| Operating Temperature | -40°C to +85°C - qualified for industrial and telecom environments without derating |
Pinout & Package
MAX6710PUT is housed in a 6-pin SOT23-6 package (JEDEC MO-178AA), footprint-compatible with standard SOT-23 pick-and-place equipment and PCB land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN1 | Adjustable voltage monitor input | Accepts external resistor divider; threshold = 0.62V × (R1+R2)/R2; ±0.4µA max input bias |
| 2 - IN2 | Power supply input & monitored rail | 3.0V ±5% monitored supply; also powers device; RESET valid if IN2 >1V |
| 3 - IN3 | Fixed-threshold voltage monitor input | 1.8V ±5% monitored supply; no external components required |
| 4 - IN4 | Adjustable voltage monitor input | Same electrical behavior as IN1; independent threshold setting |
| 5 - GND | Analog and digital ground reference | Common return for all inputs and RESET; must be low-impedance |
| 6 - RESET | Active-low open-drain reset output | Pulled up internally to IN2 (10µA); compatible with 0–5.5V logic; no external pullup needed in most cases |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitoring | Simultaneously supervises four rails with mixed fixed/adjustable thresholds-replaces four discrete supervisors or complex discrete networks |
| Factory-trimmed 3.0V/1.8V thresholds | Eliminates calibration resistors and layout area for IN2/IN3; ±5% tolerance meets common LDO and ASIC supply specs |
| 0.62V adjustable reference accuracy | Enables precise monitoring of sub-1.8V rails (e.g., core voltages, FPGA I/O) with <1% error using ≤100kΩ resistors |
| 140ms min reset timeout | Guarantees µP reset assertion long enough for full system initialization, even after fast supply recovery |
| Transient-immune comparator design | Rejects supply glitches <100µs duration-prevents spurious resets in electrically noisy industrial or telecom backplanes |
Applications
| Telecom Power Sequencing | Industrial PLC I/O Modules |
|---|---|
Use Scenario: Monitoring multiple isolated DC/DC outputs (3.3V, 1.8V, and two auxiliary rails) in a line-card power subsystem. IC Role / Device Role / Timing Role: Quad-voltage supervisor providing synchronized reset assertion across all rails before FPGA configuration begins. Use Value: Single MAX6710PUT replaces four discrete supervisors, reducing BOM count by 75% and PCB area by >40% while guaranteeing 140ms reset hold time. |
Use Scenario: Ensuring safe startup of analog sensor front-ends and digital controllers in modular I/O chassis with mixed 3.0V and 1.8V domains. IC Role / Device Role / Timing Role: Supervisory circuit asserting RESET until both main 3.0V logic rail and 1.8V ADC reference rail are stable. Use Value: Factory-trimmed thresholds eliminate calibration overhead; adjustable inputs support future revision with new low-voltage sensors without board redesign. |
| Network Equipment Line Cards | High-End Printer Engine Control |
Use Scenario: Validating power integrity across CPU core, memory, PHY, and management rails in 1RU switch line cards. IC Role / Device Role / Timing Role: Centralized voltage monitor triggering system-wide reset if any rail dips during hot-swap insertion or load transients. Use Value: Immunity to short transients (<100µs) prevents false resets during dynamic link training or packet burst activity. |
Use Scenario: Coordinating power-up of laser diode drivers, stepper motor controllers, and image processing ASICs requiring strict voltage sequencing. IC Role / Device Role / Timing Role: Supervisor ensuring 1.8V imaging core and 3.0V motor control rails meet timing margins before enabling high-current loads. Use Value: 35µA quiescent current minimizes standby loss in always-on printer control units; SOT23-6 fits tight thermal zones near print-head drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6711PUT | Same pinout and function but with 10% tolerance on IN2 (3.0V ±10%) and IN3 (1.8V ±10%) | Suitable where looser supply margin is acceptable (e.g., non-critical auxiliary rails) | Select MAX6711PUT only when ±10% threshold tolerance satisfies system-level brownout requirements |
| TPS3307-18D | Triple-supply monitor (not quad); fixed 3.3V/3.0V/1.8V thresholds; no adjustable inputs; 200ms reset timeout | Lacks fourth monitor channel and adjustability-requires supplemental circuitry for fourth rail | Choose TPS3307-18D only when exactly three rails need supervision and no future expansion is planned |
Compared with MAX6710PUT, MAX6711PUT trades tighter threshold accuracy for broader tolerance margins, while TPS3307-18D reduces channel count and flexibility to achieve lower cost in simpler systems-neither offers drop-in replacement capability due to differing input count and adjustability.

FAQ
What is the exact power supply source for MAX6710PUT?
The MAX6710PUT derives all operating power exclusively from the IN2 pin, which is configured as a 3.0V ±5% monitored supply in this variant. Unlike the MAX6710Q version, it has no separate VCC pin. The RESET output remains functional as long as IN2 or IN1 exceeds 1.0V, enabling robust operation during partial supply collapse.
Can MAX6710PUT monitor a 2.5V rail?
No-MAX6710PUT is specifically configured to monitor IN2 = 3.0V ±5% and IN3 = 1.8V ±5% with factory-trimmed thresholds. To supervise a 2.5V rail, select a different suffix (e.g., MAX6710AUT or MAX6710BUT) or use one of the adjustable inputs (IN1 or IN4) with an external resistor divider scaled to 2.5V.
What is the maximum allowable input current on IN1 and IN4 for accurate threshold setting?
The MAX6710PUT specifies ±0.4µA maximum input bias current on IN1 and ±0.2µA on IN4. When designing external resistor dividers, total Thevenin resistance should remain ≤100kΩ to maintain <1% threshold error-verified in the datasheet's "Adjustable Thresholds" section and supported by Figure 4 calculations.
Does MAX6710PUT require external pull-up resistors on the RESET pin?
No-MAX6710PUT includes a 10µA internal pullup to IN2, sufficient to drive standard CMOS inputs. An external pullup is only needed when interfacing with logic running at a different voltage (e.g., 5V MCU with 3.0V IN2), and even then, the internal circuitry blocks reverse current flow from the external rail into IN2.
How does MAX6710PUT handle brief supply glitches?
MAX6710PUT rejects transients shorter than ~100µs, as characterized in Figure MAX6710 toc04. This immunity is achieved through internal filtering and comparator hysteresis (0.3% of threshold), preventing false resets during switching noise, hot-swap events, or burst-mode load changes-critical in telecom and industrial environments.
