Product details
Overview
MAX6711MEXS+T10 from Maxim Integrated is a precision microprocessor supervisory circuit with push-pull active-low RESET output, designed to monitor +3.3V power supplies in embedded systems. It features a 2.93V reset threshold (±0.03V at +25°C), 140ms minimum reset timeout, 12µA supply current at +25°C, and guaranteed reset validity down to VCC = +1V. It is used in portable battery-powered equipment requiring reliable power-on reset and manual reset capability.
For engineers reviewing the MAX6711MEXS+T10 datasheet, MAX6711MEXS+T10 pinout, MAX6711MEXS+T10 application, or MAX6711MEXS+T10 equivalent, key selection criteria include reset threshold accuracy for 3.3V systems, SC70-4 package footprint compatibility, manual reset input timing (200ns MR-to-reset delay), and operation across –40°C to +125°C industrial temperature range.
Technical Context
The MAX6711MEXS+T10 integrates a precision voltage comparator with 30ppm/°C tempco, internal 20kΩ MR pull-up resistor, and glitch-immune reset logic that ignores transients ≤100ns on MR and ≤20µs (at 100mV overdrive) on VCC. Its push-pull output drives CMOS/TTL loads directly without external components.
It operates across full VCC range of 1.2V to 5.5V (–40°C to +105°C), asserts RESET when VCC falls below 2.93V, holds RESET active ≥140ms after VCC recovers, and maintains valid logic states down to VCC = 1V - enabling robust brownout detection in low-voltage microcontroller systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93V ±0.03V at +25°C; ensures reliable reset assertion before 3.3V supply drops below 3.0V nominal operating margin. |
| Reset Timeout | 140ms min after VCC rise; guarantees µP initialization completes before release from reset state. |
| Supply Current | 12µA typical at +25°C; enables multi-year battery life in portable instrumentation and handheld devices. |
| Operating Temp | –40°C to +125°C; supports deployment in automotive under-hood, industrial PLC, and telecom infrastructure environments. |
| VCC Range | 1.2V to 5.5V; allows use with 2.5V, 3.0V, 3.3V, and 5.0V logic families without external level-shifting. |
| MR Input Logic | Active-low with 0.3×VCC VIH/0.7×VCC VIL thresholds; compatible with standard CMOS/TTL drivers and momentary switches to GND. |
| Output Type | Push-pull active-low RESET; eliminates need for external pull-up resistor and simplifies interface to µP reset inputs. |
Pinout & Package
Package: 4-pin SC70 (X4-1 outline, 21-0098 land pattern), 1.3mm × 1.1mm footprint, 0.65mm pitch, RoHS-compliant lead-free (+T suffix).
| 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 and noise immunity. |
| 2 RESET | Active-low push-pull reset output | Drives low during reset assertion; sinks up to 1.2mA at 0.3V max VOL; interfaces directly to µP reset pins without external components. |
| 3 MR | Manual reset input | Active-low input with internal 20kΩ pull-up; accepts TTL/CMOS logic or switch-to-ground; 1µs minimum pulse width required. |
| 4 VCC | Supply voltage input | Accepts 1.2V–5.5V; powers internal comparator and output stage; requires local 0.1µF bypass capacitor for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.93V threshold | ±0.03V tolerance at +25°C ensures reset triggers within 100mV of 3.3V supply collapse - tighter than standard ±5% supervisors. |
| No external components | Integrated MR pull-up, precision reference, and push-pull driver eliminate discrete resistors, capacitors, and comparators. |
| 140ms min reset timeout | Guaranteed hold time exceeds typical µP power-up sequencing requirements for ARM Cortex-M and PIC microcontrollers. |
| VCC = 1V reset validity | RESET remains asserted and electrically valid down to 1V supply - critical for detecting deep brownout in Li-ion powered systems. |
| SC70-4 footprint | Ultra-small 1.3mm × 1.1mm package enables high-density PCB layouts in space-constrained portable medical and IoT sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UR29 | 2.93V reset threshold, SOT23-3 package, no manual reset input, 1.6µA supply current | Lacks MR pin; suitable only for power-on reset-only designs without field service or test mode requirements | Select when board space is constrained and manual reset is unnecessary; requires redesign for MR functionality |
| TPS3808G33DBVR | 3.08V reset threshold, SOT23-6 package, adjustable delay, 2.5µA supply current, integrated watchdog timer | Higher threshold (3.08V) and added watchdog function increase complexity but improve noise margin on noisy 3.3V rails | Choose when system requires both reset supervision and watchdog timeout for firmware hang detection |
Compared with MAX6711MEXS+T10, MAX6326UR29 saves power and area but removes manual reset capability, while TPS3808G33DBVR adds watchdog functionality at the cost of larger footprint and higher threshold - making MAX6711MEXS+T10 optimal for compact, MR-enabled 3.3V systems needing precise 2.93V brownout detection.

FAQ
What is the exact reset threshold voltage of the MAX6711MEXS+T10?
The MAX6711MEXS+T10 has a nominal reset threshold of 2.93V at +25°C, with ±0.03V tolerance over temperature. This value is confirmed in the Selector Guide and Electrical Characteristics table for the "S" suffix variant, and applies across the full –40°C to +125°C operating range with 30ppm/°C tempco. The MAX6711MEXS+T10 is specifically calibrated for 3.3V supply monitoring.
Does the MAX6711MEXS+T10 require an external pull-up resistor on the RESET pin?
No, the MAX6711MEXS+T10 uses a push-pull output stage, so it actively drives both high and low states on the RESET pin without requiring an external pull-up resistor. This distinguishes it from the open-drain MAX6713 variants and simplifies PCB layout. The MAX6711MEXS+T10 RESET output sources up to 500µA and sinks up to 1.2mA while maintaining specified VOH/VOL levels.
What is the function of the MR pin on the MAX6711MEXS+T10 and how should it be used?
The MR (Manual Reset) pin on the MAX6711MEXS+T10 is an active-low input with an internal 20kΩ pull-up resistor. It can be left unconnected, tied to VCC, or pulled to ground via a momentary switch to initiate a system reset. The MAX6711MEXS+T10 holds RESET asserted for at least 140ms after MR is released, and ignores glitches shorter than 100ns. No external debounce circuitry is needed.
Can the MAX6711MEXS+T10 operate reliably at VCC = 1.2V?
Yes, the MAX6711MEXS+T10 is fully specified to operate down to VCC = 1.2V over the –40°C to +105°C temperature range, and its RESET output remains valid (asserted low) down to VCC = 1.0V. Below 1.0V, the output becomes high-impedance, but this is outside normal operating conditions. The MAX6711MEXS+T10's guaranteed functionality at 1.2V supports use with low-voltage microcontrollers and energy-harvesting systems.
What package type and dimensions does the MAX6711MEXS+T10 use?
The MAX6711MEXS+T10 uses a 4-pin SC70 package (outline X4-1, land pattern 21-0098), measuring 1.3mm × 1.1mm with 0.65mm pin pitch. It is RoHS-compliant and lead-free, indicated by the "+T" suffix. This ultra-compact footprint is ideal for space-constrained applications such as wearable sensors and miniaturized test equipment where the MAX6711MEXS+T10 provides critical power supervision without consuming board area.
