Product details
Overview
MAX6711TEXS+T from Maxim Integrated is a precision microprocessor supervisory circuit with push-pull active-low RESET output, designed to monitor +3.0V supply rails in embedded digital systems. It asserts reset when VCC falls below 3.08V (typ), maintains reset for ≥140ms after power-up, and features a debounced manual reset input (MR) with internal 20kΩ pull-up. Used in portable equipment, critical µP power monitoring, and intelligent instruments.
For engineers reviewing the MAX6711TEXS+T datasheet, MAX6711TEXS+T pinout, MAX6711TEXS+T application, or MAX6711TEXS+T equivalent, key selection factors include its 3.0V-specific reset threshold, 12µA supply current at +25°C, guaranteed reset validity down to VCC = +1V, and SC70-4 package compatibility with space-constrained designs.
Technical Context
The MAX6711TEXS+T implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to detect VCC drops below its factory-trimmed 3.08V threshold. Its push-pull output drives low actively and high via internal transistor-no external pull-up required. Reset assertion is immune to transients ≤20µs at 100mV overdrive.
Manual reset (MR) is an active-low input with TTL/CMOS-compatible thresholds (VIL = 0.3×VCC, VIH = 0.7×VCC), 1µs minimum pulse width, and 100ns glitch immunity. The device guarantees correct logic state for VCC as low as 1V and operates across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08V (typ) at +25°C; ensures reliable brownout detection before µP operational failure on 3.0V rails |
| Supply Current | 12µA (typ) at VCC < 3.6V and TA = –40°C to +85°C; enables multi-year battery life in portable equipment |
| Reset Timeout | 140ms min after VCC rise above threshold; meets JEDEC JESD78 requirement for power-on reset duration |
| Operating Temp | –40°C to +125°C; supports industrial and automotive under-hood applications without derating |
| VCC Range | 1.0V to 5.5V; allows valid reset signaling during deep brownout and full-system power sequencing |
| Output Type | Active-low push-pull RESET; eliminates need for external pull-up resistor and simplifies µP interface |
| MR Input | Internal 20kΩ pull-up; enables direct switch-to-ground connection with no external components |
Pinout & Package
MAX6711TEXS+T is housed in a 4-pin SC70 package (outline X4-1, land pattern 90-0187), measuring 1.25mm × 0.85mm × 0.55mm. This ultra-small outline supports high-density PCB layouts in handheld and IoT edge devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Return path for all internal circuitry; must be connected to system ground plane for stable reset threshold |
| 2 RESET | Active-low push-pull reset output | Drives µP /RESET pin low during fault; returns high actively-no external pull-up needed |
| 3 MR | Active-low manual reset input | Asserts reset when pulled low; internal 20kΩ pull-up allows direct switch connection to GND |
| 4 VCC | Supply voltage input | Monitored +3.0V rail; powers internal circuitry and defines MR logic thresholds (VIL/VIH) |
Key Features
| Feature | Design Value |
|---|---|
| Precision 3.0V reset threshold | Factory-trimmed 3.08V ±0.04V at +25°C with 30ppm/°C tempco-enables tight margining on 3.0V systems |
| No external components | Integrated MR pull-up, push-pull output, and voltage reference eliminate BOM cost and layout area |
| 140ms min reset timeout | Guaranteed minimum pulse width ensures µP completes internal initialization before release |
| VCC = +1V reset validity | RESET remains functional down to 1V supply-critical for controlled shutdown in battery-powered systems |
| Transient immunity | Rejects VCC glitches ≤20µs at 100mV overdrive-prevents spurious resets in noisy power environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6711TES+T | Same 3.08V threshold and push-pull output, but in leaded (non-RoHS) SC70 package | Requires leaded assembly process; not suitable for RoHS-compliant production | Select MAX6711TEXS+T for lead-free manufacturing; use MAX6711TES+T only if legacy leaded process is mandated |
| TPS3123E18DBVR | 3.08V threshold, open-drain output, 1.8V–5.5V VCC range, 2.5µA quiescent current | Lacks manual reset input; requires external pull-up; optimized for ultra-low-power, not manual intervention | Choose TPS3123E18DBVR only when minimal current draw (<3µA) outweighs need for MR functionality |
Compared with MAX6711TEXS+T, MAX6711TES+T offers identical electrical performance but incompatible RoHS status, while TPS3123E18DBVR trades manual reset capability and push-pull drive for lower supply current-making it unsuitable as a drop-in replacement.

FAQ
What is the reset threshold voltage of the MAX6711TEXS+T?
The MAX6711TEXS+T has a factory-trimmed reset threshold of 3.08V (typical) at +25°C, with guaranteed limits of 3.04V to 3.11V across temperature. This precise threshold ensures reliable detection of brownout conditions on +3.0V supply rails without false triggering during normal operation.
Does the MAX6711TEXS+T require an external pull-up resistor on its RESET pin?
No. The MAX6711TEXS+T features a push-pull RESET output, meaning it actively drives both high and low states. Unlike open-drain supervisors, the MAX6711TEXS+T does not require an external pull-up resistor-reducing BOM count and simplifying layout.
Can the MAX6711TEXS+T operate with supply voltages below 3.0V?
Yes. The MAX6711TEXS+T functions across a VCC range of 1.0V to 5.5V. While it is optimized for monitoring +3.0V rails, its internal circuitry remains operational down to 1.0V, and the RESET output is guaranteed valid until VCC reaches +1V-critical for controlled shutdown sequences.
What is the purpose of the MR pin on the MAX6711TEXS+T?
The MR (Manual Reset) pin on the MAX6711TEXS+T is an active-low input that forces RESET assertion when pulled low. It includes an internal 20kΩ pull-up resistor, allowing direct connection to a momentary switch grounded to initiate system reset-no external components or debounce circuitry required.
Is the MAX6711TEXS+T compatible with lead-free PCB assembly processes?
Yes. The "+T" suffix in MAX6711TEXS+T explicitly denotes lead-free (RoHS-compliant) packaging. It uses matte tin lead finish and is qualified for standard Pb-free reflow profiles, making it suitable for modern environmentally compliant manufacturing.
