Product details
Overview
MAX6713LEXS-T 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. It is used in critical µP systems requiring reliable power monitoring and manual reset capability.
For engineers reviewing the MAX6713LEXS-T datasheet, MAX6713LEXS-T pinout, MAX6713LEXS-T application, or MAX6713LEXS-T equivalent, key selection considerations include its open-drain output architecture, 4-pin SC70 package, -40°C to +125°C operating range, compatibility with 5V systems, and absence of external components for basic reset functionality.
Technical Context
The MAX6713LEXS-T implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to detect VCC falling below its 4.63V threshold. Its reset assertion is synchronized to VCC recovery with a guaranteed 140ms minimum timeout after VCC exceeds VTH, independent of temperature across -40°C to +125°C.
It integrates a debounced manual reset input (MR) with internal 20kΩ pull-up, supporting TTL/CMOS logic drive and switch-to-ground interfaces. The open-drain RESET output requires an external pull-up resistor and supports level-shifting-e.g., pulling up to a voltage higher than VCC-enabling interoperability with bidirectional µP reset pins like those on Motorola 68HC11.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63V ±0.07V at +25°C; ensures reset assertion before 5V supply drops beyond 5% nominal tolerance. |
| Reset Timeout | 140ms min after VCC rise above threshold; guarantees µP initialization completes before release. |
| Supply Current | 12µA typical at +25°C; enables use in battery-powered equipment without significant drain. |
| Operating Range | -40°C to +125°C; supports industrial and automotive-adjacent embedded applications. |
| VCC Validity | RESET remains valid down to VCC = +1V; prevents undefined logic states during deep brownout. |
| Output Type | Open-drain active-low RESET; allows wired-OR configuration and level-shifting with external pull-up. |
| Transient Immunity | Rejects VCC glitches ≤20µs at 100mV overdrive; avoids spurious resets in noisy power environments. |
Pinout & Package
MAX6713LEXS-T is housed in a 4-pin SC70 package (outline X4-1), measuring 2.0mm × 2.1mm × 0.95mm, with gull-wing leads and RoHS-compliant lead-free finish (denoted by "+T" suffix; "-T" indicates standard leaded).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Return path for internal circuitry and MR input; must be low-impedance connection to system ground plane. |
| 2 RESET | Open-drain active-low reset output | Sinks current when asserted; requires external pull-up to define high state-supports voltages up to +6.0V. |
| 3 MR | Manual reset input | Active-low; internally pulled up to VCC via 20kΩ; accepts TTL/CMOS logic or momentary switch to GND. |
| 4 VCC | Supply voltage input | Accepts +2.5V to +5.5V; powers internal comparator and logic; reset function remains valid down to +1.0V. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.63V threshold | Enables tight margining for +5V systems-asserts reset before supply falls below 4.6V, avoiding marginal µP operation. |
| 140ms min reset pulse width | Guarantees sufficient time for µP clock stabilization and register initialization before release. |
| Open-drain RESET output | Permits shared reset bus with other open-drain devices and level-shifting to higher-voltage domains (e.g., 5V reset control of 3.3V µP). |
| MR with internal 20kΩ pull-up | Eliminates need for external pull-up; simplifies PCB layout and supports direct switch-to-ground manual reset. |
| 12µA supply current | Reduces quiescent load on battery or low-power rails-critical for portable instrumentation and handheld controllers. |
Applications
| Critical µP Power Monitoring | Portable/Battery-Powered Equipment |
|---|---|
Use Scenario: Monitoring +5V rail in industrial PLC controller during cold start and line sag.

Use Value: Guaranteed 140ms reset hold-off ensures all peripherals are fully powered before µP begins I²C initialization. |
Use Scenario: Compact embedded PC motherboard using Intel Atom processor with 5V auxiliary rail. IC Role / Device Role / Timing Role: Secondary reset supervisor for peripheral controller FPGA, triggered by manual reset button or VCC brownout. Use Value: MR input debouncing eliminates external RC filter; open-drain RESET interfaces directly with FPGA's bidirectional reset I/O pin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6711LEXS-T | Push-pull active-low RESET output; no external pull-up required; same 4.63V threshold and 140ms timeout. | Preferred where single-supply reset signaling is sufficient and board space prohibits pull-up resistor placement. | Select when system does not require level-shifting or wired-OR reset bus capability. |
| TPS3808G18DBVR | Fixed 1.8V reset threshold; push-pull output; 200ms reset timeout; 1.4µA typical ICC; SOT-23-5 package. | Designed for low-voltage µPs (e.g., 1.8V core); incompatible with 5V monitoring without external divider. | Choose only for sub-2V supply supervision-not a functional substitute for MAX6713LEXS-T's 4.63V 5V-rail role. |
Compared with MAX6711LEXS-T, MAX6713LEXS-T provides open-drain flexibility for multi-rail systems but requires a pull-up; compared with TPS3808G18DBVR, it serves a fundamentally different voltage domain and cannot replace 5V supervision without redesign.

FAQ
What is the reset threshold voltage of the MAX6713LEXS-T?
The MAX6713LEXS-T has a nominal reset threshold of 4.63V at +25°C, with a tolerance of ±0.07V. Over temperature (-40°C to +125°C), the threshold varies within 4.40V to 4.86V for the L-grade version. This value is factory-trimmed and specified in the Electrical Characteristics table of the MAX6713LEXS-T datasheet, ensuring precise detection of +5V supply brownout conditions.
Does the MAX6713LEXS-T require an external pull-up resistor on the RESET pin?
Yes, the MAX6713LEXS-T features an open-drain RESET output and requires an external pull-up resistor to establish a defined high logic state. The pull-up may connect to any voltage between 0V and +6.0V-including supplies higher than VCC-enabling level-shifting. Typical values range from 10kΩ to 100kΩ depending on bus capacitance and drive strength requirements.
Can the MAX6713LEXS-T operate with VCC below 1.0V?
The MAX6713LEXS-T guarantees correct reset behavior down to VCC = +1.0V. Below this, the RESET output ceases sinking current and becomes high-impedance. For applications requiring valid RESET down to 0V, a 100kΩ pull-down resistor on the RESET line is recommended to prevent floating states, as documented in the MAX6713LEXS-T application note on "Ensuring a Valid Reset Output Down to VCC = 0".
What is the function of the MR pin on the MAX6713LEXS-T?
The MR (Manual Reset) pin on the MAX6713LEXS-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 at the other end. MR deassertion triggers a 140ms minimum reset timeout, matching the power-on reset duration. No external debounce components are needed due to built-in glitch immunity.
Is the MAX6713LEXS-T compatible with bidirectional µP reset pins?
Yes-the open-drain architecture of the MAX6713LEXS-T RESET output makes it inherently compatible with bidirectional reset pins, such as those found on Motorola 68HC11 and certain ARM-based microcontrollers. When connected via a shared pull-up resistor, either the MAX6713LEXS-T or the µP can assert reset on the same line, enabling coordinated system-level reset control without additional logic.
