Product details
Overview
MAX6713LEXS 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 or power-up events. It features a 4.63V reset threshold (±0.5% over temperature), 140ms minimum reset timeout, 12µA supply current, and guaranteed operation down to VCC = +1V. Used in automotive and industrial controllers for reliable µP initialization.
For engineers reviewing the MAX6713LEXS datasheet, MAX6713LEXS pinout, MAX6713LEXS application, or MAX6713LEXS equivalent, key selection considerations include its SC70-4 open-drain reset architecture, manual reset input with internal 20kΩ pull-up, transient-immune reset comparator, and compatibility with multi-supply reset bus topologies.
Technical Context
The MAX6713LEXS implements a precision bandgap-based voltage comparator that monitors VCC against a factory-trimmed 4.63V threshold, with ±0.5% accuracy over –40°C to +125°C. Its reset logic includes built-in 140ms timer and debounced manual reset input (MR) with 100ns glitch immunity.
As an open-drain device, MAX6713LEXS requires an external pull-up resistor on RESET, enabling level-shifting to higher-voltage rails (up to +6.0V) and direct interfacing with bidirectional µP reset pins. The output remains valid and sinks current reliably down to VCC = +1V, with leakage <0.3µA at VCC = +1V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63V ±0.5% - precisely matches +5.0V nominal supply with 7.4% headroom before reset assertion. |
| Reset Timeout | ≥140ms - ensures µP completes power stabilization and clock lock before release. |
| Supply Current | 12µA max - enables use in always-on battery-backed systems without significant drain. |
| VCC Operating Range | +1.0V to +5.5V - guarantees functional reset assertion even during deep brownout conditions. |
| MR Input Threshold | VIL ≤ 0.3·VCC, VIH ≥ 0.7·VCC - compatible with TTL/CMOS logic and open-drain drivers. |
| RESET Output Type | Open-drain - supports wired-OR reset buses, level shifting, and bidirectional µP interfaces. |
| Temp Range | –40°C to +125°C - qualified for under-hood automotive and industrial embedded environments. |
Pinout & Package
MAX6713LEXS is housed in a 4-pin SC70-4 package (2.0mm × 2.1mm, 0.65mm pitch), optimized for space-constrained PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: RESET | Open-drain active-low reset output | Sinks current when asserted; requires external pull-up to define logic-high level and enable multi-supply interfacing. |
| 2: GND | Ground reference | Return path for VCC, MR, and RESET; must be low-impedance connection to system ground plane. |
| 3: MR | Active-low manual reset input | Internally pulled up to VCC (20kΩ); driven low by switch or logic to initiate reset; immune to <100ns noise spikes. |
| 4: VCC | Power supply input | Monitored +5.0V rail; powers internal circuitry and defines MR logic thresholds; accepts 1.0V–5.5V range. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.63V threshold | ±0.5% tolerance over full temperature range eliminates need for external calibration or trimming. |
| 140ms power-on reset pulse | Guaranteed minimum duration ensures µP clocks, PLLs, and memory initialize fully before release. |
| Open-drain RESET with 6V tolerance | Enables reset bus sharing across mixed-voltage domains (e.g., 3.3V µP controlled by 5V supervisor). |
| MR with internal 20kΩ pull-up | Reduces BOM count; allows direct switch-to-ground connection without external resistor. |
| Valid reset down to VCC = +1V | Prevents undefined µP state during deep brownout-critical for fail-safe automotive control units. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC I/O Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326LUR29 | Push-pull active-low RESET; fixed 2.93V threshold; no MR input; SOT23-3 package. | Lacks manual reset capability and open-drain flexibility; suited for simple 3.3V systems only. | Select when board space is constrained and MR functionality is unnecessary. |
| TPS3808G12DBVR | Adjustable reset threshold via external resistor divider; 200ms timeout; push-pull output; SOT23-6 package. | Requires two external resistors; larger footprint; higher quiescent current (15µA typical). | Choose when programmable threshold or longer timeout is required, accepting added components. |
Compared with MAX6713LEXS, MAX6326LUR29 offers smaller size but sacrifices MR and open-drain versatility, while TPS3808G12DBVR provides adjustability at the cost of layout complexity and reduced integration-making MAX6713LEXS optimal for fixed 5V systems needing robust, minimal-BOM supervision.

FAQ
What is the exact reset threshold voltage of the MAX6713LEXS?
The MAX6713LEXS has a factory-trimmed reset threshold of 4.63V with ±0.5% accuracy over –40°C to +125°C. This value is specified in the Electrical Characteristics table of the datasheet and applies to the "L" suffix variant, which is calibrated for +5.0V systems. The threshold remains stable across temperature and load, eliminating need for external calibration.
Does the MAX6713LEXS require an external pull-up resistor on the RESET pin?
Yes, the MAX6713LEXS features an open-drain RESET output and requires an external pull-up resistor to establish a defined logic-high level. The resistor may connect to any voltage between 0V and +6.0V-including rails higher than VCC-enabling level-shifting. Typical values range from 10kΩ to 100kΩ depending on bus capacitance and drive strength requirements.
Can the MAX6713LEXS operate with VCC below 2.5V?
Yes, the MAX6713LEXS functions down to VCC = +1.0V, and its RESET output remains valid (sinking current) throughout this range. However, the reset threshold of 4.63V means it will assert reset continuously when VCC falls below that level. Operation below 2.5V is intended for brownout detection-not normal regulation-and is fully characterized per datasheet specifications.
How does the manual reset (MR) input behave on the MAX6713LEXS?
The MR input on the MAX6713LEXS is active-low with an internal 20kΩ pull-up resistor to VCC. When pulled low (≤0.3·VCC), it asserts RESET immediately and holds it active for ≥140ms after MR returns high. It accepts TTL/CMOS logic levels and is immune to glitches <100ns, making external debounce circuitry unnecessary in most implementations.
Is the MAX6713LEXS pin-compatible with other MAX671x variants like MAX6711LEXS or MAX6712LEXS?
No, the MAX6713LEXS is not pin-compatible with MAX6711LEXS or MAX6712LEXS in terms of output behavior-though all share identical SC70-4 pinout and pin functions. The key difference is output stage: MAX6713LEXS uses open-drain RESET, while MAX6711LEXS uses push-pull active-low and MAX6712LEXS uses push-pull active-high. Circuit design must account for this fundamental interface distinction.
