Product details
Overview
MAX6713LEXS+T10 from Maxim Integrated is a precision microprocessor supervisory circuit with open-drain active-low RESET output, designed to monitor +5.0V power supplies and assert reset during brownout, power-up, or manual reset events. It features a 4.63V reset threshold (±0.07V at +25°C), 140ms minimum reset timeout, 12µA supply current at +25°C, and guaranteed operation down to VCC = +1V. Used in critical µP systems requiring reliable power monitoring and manual reset capability.
For engineers reviewing the MAX6713LEXS+T10 datasheet, MAX6713LEXS+T10 pinout, MAX6713LEXS+T10 application, or MAX6713LEXS+T10 equivalent, key selection considerations include its open-drain RESET output for level-shifting or bidirectional µP interface, SC70-4 package footprint compatibility, -40°C to +125°C operating range, and precise 4.63V threshold optimized for +5V systems.
Technical Context
The MAX6713LEXS+T10 implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to detect VCC drops below 4.63V, asserting an open-drain RESET signal that remains active for ≥140ms after recovery. Its MR input includes internal 20kΩ pull-up and accepts TTL/CMOS logic or switch-to-ground activation.
Unlike push-pull variants (MAX6711/MAX6712), the MAX6713LEXS+T10's open-drain output requires an external pull-up resistor-enabling interface with higher-voltage logic domains (up to +6.0V) or bidirectional reset pins-and guarantees valid output state down to VCC = +1V, with leakage <1µA when deasserted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63V ±0.07V at +25°C; ensures reliable detection of +5V supply brownout before µP instability occurs. |
| Reset Timeout | 140ms min after VCC rise; provides sufficient hold time for µP initialization and peripheral stabilization. |
| Supply Current | 12µA typical at +25°C; enables use in battery-powered equipment without significant standby drain. |
| VCC Operating Range | +1.0V to +5.5V; supports valid reset assertion even during deep brownout conditions down to 1V. |
| Output Type | Open-drain RESET; allows flexible pull-up to any voltage ≤+6.0V for level-shifting or shared-bus applications. |
| MR Input Threshold | VIL = 0.3×VCC, VIH = 0.7×VCC; compatible with standard TTL/CMOS logic families without level translation. |
| Temp Range | -40°C to +125°C; qualified for industrial and extended-temperature embedded control environments. |
Pinout & Package
Package: 4-pin SC70 (X4-1 outline, 21-0098 land pattern), surface-mount, lead-free (RoHS-compliant).
| 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 comparator operation. |
| 2 RESET | Open-drain active-low reset output | Sinks current when asserted; requires external pull-up resistor to define high-level voltage and drive strength. |
| 3 MR | Manual reset input (active-low) | Internal 20kΩ pull-up enables direct switch-to-ground connection; no external components needed for basic reset function. |
| 4 VCC | Supply voltage input | Monitored +5.0V rail; powers internal circuitry and defines MR logic thresholds; operates from +1.0V to +5.5V. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.63V threshold | ±0.07V tolerance at +25°C and ±0.25V over -40°C to +85°C ensures deterministic reset timing in +5V systems. |
| Open-drain RESET output | Enables level-shifting to higher-voltage domains (e.g., +3.3V µP reset driven from +5V monitored rail) and bidirectional I/O compatibility. |
| 140ms minimum reset pulse width | Guarantees µP core and peripherals complete power-up sequencing before release, eliminating race conditions. |
| 12µA supply current | Reduces battery load in portable equipment; maintains full functionality without trade-offs in accuracy or timing. |
| Valid reset down to VCC = +1V | Prevents undefined µP behavior during deep brownout by maintaining known reset state until near-complete power loss. |
Applications
| Critical µP Power Monitoring | Portable/Battery-Powered Equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6711LEXS+T10 | Push-pull active-low RESET output; no external pull-up required; VOH = 0.8×VCC at 500µA. | Better suited for single-supply +5V systems where level-shifting or bidirectional reset is unnecessary. | Select when simplifying design with fixed +5V logic domain and avoiding pull-up resistor placement. |
| TLV803EC26DBVR | Fixed 2.63V threshold, SOT-23-3 package, 1.6µA quiescent current, no manual reset input. | Limited to lower-voltage systems; lacks MR pin and open-drain flexibility; smaller footprint but no manual override. | Choose for ultra-low-power +3.3V or +2.5V applications where manual reset is not required and board space is critical. |
Compared with MAX6711LEXS+T10 and TLV803EC26DBVR, the MAX6713LEXS+T10 uniquely combines open-drain output for voltage-domain bridging, precise +5V threshold, and integrated manual reset-making it optimal for robust, multi-rail embedded controllers needing field-serviceable reset capability.

FAQ
What is the reset threshold voltage for MAX6713LEXS+T10?
The MAX6713LEXS+T10 has a nominal reset threshold of 4.63V, with ±0.07V tolerance at +25°C and guaranteed operation from 4.50V to 4.75V over -40°C to +85°C. This value is factory-trimmed and applies specifically to the L-suffix variant, making MAX6713LEXS+T10 suitable for monitoring +5.0V supplies with tight margin requirements.
Does MAX6713LEXS+T10 require an external pull-up resistor on the RESET pin?
Yes, MAX6713LEXS+T10 uses an open-drain RESET output and requires an external pull-up resistor to establish a defined high logic level. The resistor may connect to any voltage between 0V and +6.0V-including supplies different from VCC-enabling level-shifting. Typical values range from 10kΩ to 100kΩ depending on bus capacitance and drive strength needs.
Can MAX6713LEXS+T10 operate with VCC below 1.0V?
MAX6713LEXS+T10 guarantees valid RESET output behavior down to VCC = +1.0V. Below this, the output transitions to high-impedance; for applications requiring defined logic state down to 0V, a pull-down resistor (e.g., 100kΩ) on the RESET line is recommended. This behavior is explicitly characterized and confirmed for MAX6713LEXS+T10 in the datasheet.
What is the minimum reset pulse width provided by MAX6713LEXS+T10?
MAX6713LEXS+T10 asserts RESET for a minimum of 140ms after VCC rises above the threshold or after MR is released. This timeout is guaranteed over -40°C to +85°C and extends up to 460ms at elevated temperatures. The fixed delay eliminates need for external timing components and ensures reliable µP initialization across environmental conditions.
How is the manual reset (MR) input configured on MAX6713LEXS+T10?
The MR input on MAX6713LEXS+T10 is active-low with an internal 20kΩ pull-up resistor, allowing direct connection of a momentary switch to ground-no external components required. It accepts TTL/CMOS logic levels and features 100ns glitch immunity. MR assertion holds RESET active, and reset remains asserted for ≥140ms after MR returns high, providing clean debounced reset initiation.
