Product details
Overview
MAX6713TEXS+T from Maxim Integrated is a precision microprocessor supervisory circuit with open-drain active-low RESET output, designed to monitor +3.0V power supplies in embedded systems. It asserts reset when VCC falls below 3.08V (typ), maintains reset for ≥140ms after recovery, and features manual reset input with internal 20kΩ pull-up - used in portable equipment, intelligent instruments, and critical µP power monitoring.
For engineers reviewing the MAX6713TEXS+T datasheet, MAX6713TEXS+T pinout, MAX6713TEXS+T application, or MAX6713TEXS+T equivalent, key selection criteria include its 3.08V reset threshold, 12µA supply current at +3V, SC70-4 package, guaranteed reset validity down to VCC = +1V, and immunity to fast VCC transients up to 100mV overdrive.
Technical Context
The MAX6713TEXS+T implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to detect VCC drops below its factory-trimmed 3.08V threshold. Its open-drain RESET output requires an external pull-up and supports level-shifting - enabling interface with µPs powered by different rails (e.g., 3.3V supervisor driving 5V µP reset).
It integrates debounced manual reset logic with 1µs minimum pulse width and 100ns glitch immunity. The MR input remains functional down to VCC = +1V, and the device guarantees correct output logic state across –40°C to +125°C while consuming only 12µA typical supply current at VCC = +3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08V (typ) at +25°C; ensures reliable brownout detection before µP operational failure at +3.0V nominal supply. |
| Supply Current | 12µA (typ) at VCC = +3.0V; enables multi-year battery life in portable equipment. |
| Reset Timeout | ≥140ms after VCC rise above threshold; satisfies Intel/ARM µP power-on reset timing requirements. |
| Operating Temp | –40°C to +125°C; qualified for industrial and automotive under-hood environments. |
| VCC Range | 1.0V to 5.5V; allows valid reset assertion even during deep brownout or partial power loss. |
| MR Input | Internal 20kΩ pull-up; eliminates external resistor for basic manual reset switch implementation. |
| RESET Output | Open-drain, 1µA leakage max when deasserted; supports wired-OR configuration and multi-rail level shifting. |
Pinout & Package
MAX6713TEXS+T is housed in a 4-pin SC70 package (outline X4-1, land pattern 90-0187), measuring 1.25mm × 0.85mm × 0.55mm - compatible with high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Return path for all internal circuitry; must be low-impedance connection to system ground plane. |
| 2 RESET | Open-drain active-low reset output | Drives low during reset; requires external pull-up to define logic-high voltage (up to +6.0V); sinks ≥1.2mA. |
| 3 MR | Active-low manual reset input | Pulled internally to VCC via 20kΩ; assert by grounding; immune to <100ns noise spikes. |
| 4 VCC | Supply input | Monitored +3.0V rail; absolute max rating +6.0V; functional down to +1.0V. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 3.08V threshold | ±1.5% accuracy over temperature eliminates need for external calibration or trimming resistors. |
| 140ms min reset timeout | Guaranteed across full temperature range ensures µP initialization completes before code execution begins. |
| Open-drain RESET with 6V tolerance | Enables direct interface to higher-voltage logic domains without level translators or additional components. |
| MR with integrated 20kΩ pull-up | Reduces BOM count and PCB area; supports direct switch-to-ground connection without external biasing. |
| 12µA supply current at +3V | Extends battery runtime in handheld meters and sensor nodes where duty-cycled operation is critical. |

|
Use Scenario: Revenue-grade electricity meter with dual-supply architecture (3.3V MCU + 2.5V metrology ASIC) and tamper-detection circuitry. IC Role / Device Role / Timing Role: Provides independent reset supervision for the 3.3V domain; MR tied to mechanical tamper switch. Use Value: Open-drain RESET allows shared pull-up to 5V backup rail, ensuring reset assertion persists during main supply failure. |
Use Scenario: Door module controlling window lift, mirror fold, and interior lighting using a 3.0V core supply derived from vehicle battery. IC Role / Device Role / Timing Role: Detects battery brownout during cold-cranking (VCC dip to ~2.8V) and holds MCU in reset until stable 3.0V resumes. Use Value: 3.08V threshold triggers reset 20mV before µP specification limit, preventing corrupted EEPROM writes during voltage sag. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316MUT46D3+T | Push-pull active-low RESET; 4.63V threshold; same SC70-4 package. | Lacks open-drain flexibility; unsuitable for level-shifting or wired-OR reset buses. | Select when system uses only +5V logic and requires no external pull-up. |
| TPS3808G30DBVR | Open-drain RESET; 3.0V threshold; 1.5µA supply current; SOT-23-5 package. | Extra EN pin enables enable-controlled supervision; larger footprint and different pinout. | Select when ultra-low current dominates design priority and board space permits SOT-23-5. |
Compared with MAX6713TEXS+T, MAX6316MUT46D3+T offers identical form factor but lacks level-shifting capability, while TPS3808G30DBVR reduces current consumption by 8x but requires PCB redesign due to 5-pin SOT-23 and added enable functionality.

FAQ
What is the exact reset threshold voltage of MAX6713TEXS+T and how does it vary with temperature?
The MAX6713TEXS+T has a nominal reset threshold of 3.08V at +25°C, with guaranteed limits of 3.00V to 3.15V over –40°C to +85°C and 2.92V to 3.23V over +85°C to +105°C. Its temperature coefficient is 30ppm/°C, meaning threshold drift is ≤±12mV across the full –40°C to +125°C range - sufficient for stable operation in industrial temperature gradients without recalibration.
Does MAX6713TEXS+T require an external pull-up resistor on the RESET pin, and what value is recommended?
Yes, MAX6713TEXS+T requires an external pull-up resistor on the RESET pin because it features an open-drain output. A 10kΩ to 100kΩ resistor pulled to any voltage between 0V and +6.0V is recommended; 47kΩ is commonly used for optimal rise time and current consumption trade-off. This enables level-shifting - e.g., pulling RESET to +5V while monitoring a +3.0V VCC rail.
Can MAX6713TEXS+T operate reliably when VCC drops below 1.0V, and what happens to the RESET output?
MAX6713TEXS+T guarantees correct RESET logic state down to VCC = +1.0V. Below +1.0V, the RESET output ceases sinking current and becomes high-impedance. To maintain a defined low state during deep brownout, a 100kΩ pull-down resistor to GND is recommended - this ensures µP reset remains asserted even as VCC collapses toward 0V, preventing undefined startup behavior.
How is the manual reset (MR) input configured on MAX6713TEXS+T, and does it need external components?
The MR input on MAX6713TEXS+T includes an internal 20kΩ pull-up resistor to VCC, so no external components are required for basic operation. Assert reset by momentarily shorting MR to GND via a normally-open switch. For noisy environments or long traces, adding a 0.1µF capacitor from MR to GND improves immunity without affecting debounce performance - the device inherently rejects glitches <100ns.
What package type and dimensions does MAX6713TEXS+T use, and is it RoHS-compliant?
MAX6713TEXS+T uses a 4-pin SC70 package (outline X4-1), measuring 1.25mm × 0.85mm × 0.55mm with 0.65mm pin pitch. The "+T" suffix confirms lead-free, RoHS-compliant construction per JEDEC J-STD-020. Land pattern 90-0187 is recommended for reliable reflow soldering, and the package supports standard automated assembly processes including SPI inspection and AOI.
