Product details
Overview
MAX6713SEXS+T10 from Maxim Integrated is a precision microprocessor supervisory circuit with open-drain active-low RESET output, designed to monitor +2.93V power supplies in embedded systems. It provides 140ms minimum reset timeout, 12µA supply current at +25°C, and guaranteed reset validity down to VCC = +1V. Used in portable equipment and critical µP systems for reliable power-on/brownout detection.
For engineers reviewing the MAX6713SEXS+T10 datasheet, MAX6713SEXS+T10 pinout, MAX6713SEXS+T10 application, or MAX6713SEXS+T10 equivalent, key selection criteria include reset threshold accuracy (2.93V ±30mV at +25°C), SC70-4 package compatibility, manual reset input timing (200ns MR-to-reset delay), and open-drain output flexibility for multi-supply level-shifting.
Technical Context
The MAX6713SEXS+T10 implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to detect VCC drops below its 2.93V threshold. Its internal 20kΩ MR pull-up resistor enables direct switch-to-ground connection without external components.
Reset assertion is latched and held for ≥140ms after VCC recovery or MR deassertion, independent of temperature (100–460ms range over -40°C to +125°C). The open-drain RESET output supports pull-up to any voltage ≤6.0V, enabling interface with µPs having bidirectional reset pins or higher-voltage logic domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93V ±30mV at +25°C; ensures reliable detection before 5% supply deviation from nominal +3.0V rail |
| Supply Current | 12µA typical at +25°C; enables >1-year battery life in coin-cell-powered instrumentation |
| Reset Timeout | 140ms minimum after VCC rise; meets µP minimum reset pulse width requirements across full temperature range |
| VCC Operating Range | +1.0V to +5.5V; guarantees functional reset assertion even during deep brownout conditions |
| MR Input Threshold | 0.3×VCC low / 0.7×VCC high; compatible with TTL and CMOS logic families without level-shifting |
| RESET Output Type | Open-drain; allows pull-up to voltage higher than VCC for mixed-supply system interfacing |
| Package | 4-pin SC70 (X4-1 outline); 1.3mm × 0.8mm footprint ideal for space-constrained portable designs |
Pinout & Package
MAX6713SEXS+T10 is housed in a 4-pin SC70 package (outline X4-1), measuring 1.3mm × 0.8mm × 0.6mm with gull-wing leads. This ultra-compact leaded package supports reflow soldering and is RoHS-compliant (indicated by '+' suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Return path for all internal circuitry; must be connected directly to system ground plane |
| 2 RESET | Open-drain active-low reset output | Sinks current when asserted; requires external pull-up resistor to define logic-high voltage level |
| 3 MR | Active-low manual reset input | Internally pulled up to VCC via 20kΩ resistor; driven low to initiate reset sequence |
| 4 VCC | Supply voltage input | Monitored +2.93V rail; powers internal circuitry and sets MR logic thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.93V threshold | ±30mV tolerance at +25°C ensures reset occurs within 1% of nominal +3.0V supply, eliminating uncertainty zones |
| 140ms min reset timeout | Guaranteed minimum pulse width satisfies µP reset timing requirements across -40°C to +125°C operating range |
| 12µA supply current | Enables use in always-on battery-backed applications without compromising runtime |
| Open-drain RESET output | Supports level-shifting to higher-voltage logic domains (e.g., 5V µP reset input from 3.0V monitored rail) |
| MR glitch immunity | 100ns minimum pulse rejection prevents spurious resets from EMI or switch bounce |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6713TEXS+T10 | 3.08V reset threshold (vs. 2.93V); identical SC70-4 package and open-drain output | Targeted for +3.3V systems with tighter margin; not suitable for 2.93V LDO outputs | Select when monitoring +3.3V rails where 3.08V threshold provides optimal noise margin |
| TPS3808G12DBVR | 3.08V threshold, push-pull output, 1.5µA quiescent current; SOT-23-5 package | Lacks manual reset input; optimized for ultra-low-power applications without operator intervention | Choose for battery-critical designs where MR functionality is unnecessary and 1.5µA ICC is mandatory |
Compared with MAX6713SEXS+T10, the MAX6713TEXS+T10 offers higher threshold accuracy for +3.3V systems but cannot replace it in 2.93V applications, while the TPS3808G12DBVR reduces supply current by 8x but removes manual reset capability and changes package pinout.

FAQ
What is the exact reset threshold voltage for MAX6713SEXS+T10 and how does it vary with temperature?
The MAX6713SEXS+T10 has a nominal reset threshold of 2.93V at +25°C, with ±30mV initial tolerance. Over the full -40°C to +125°C operating range, the threshold drifts no more than ±75mV (2.855V to 3.005V) due to its 30ppm/°C tempco. This stability ensures consistent brownout detection across extreme environments without recalibration.
Does MAX6713SEXS+T10 require an external pull-up resistor on the RESET pin, and what value is recommended?
Yes, MAX6713SEXS+T10 requires an external pull-up resistor on the RESET pin because it features an open-drain output. A 10kΩ to 100kΩ resistor pulled to the target logic voltage (e.g., 3.3V or 5.0V) is recommended. Lower values improve noise immunity but increase quiescent current; higher values reduce current but may slow rise time in high-capacitance nodes.
Can MAX6713SEXS+T10 operate reliably when VCC drops below 1.0V, and what happens to the RESET output?
MAX6713SEXS+T10 guarantees reset functionality down to VCC = +1.0V, but below this voltage, the RESET output stops sinking current and becomes high-impedance. To maintain valid logic levels in systems requiring RESET assertion to ground at VCC = 0V, a 100kΩ pull-down resistor on the RESET line is recommended per Maxim's application guidance for MAX6713SEXS+T10.
How does the manual reset (MR) input of MAX6713SEXS+T10 behave during power-up and what is its minimum pulse width requirement?
The MR input of MAX6713SEXS+T10 is internally pulled up to VCC with a 20kΩ resistor and triggers reset when driven low. It requires a minimum 1µs pulse width to register, with 200ns propagation delay from MR deassertion to RESET deassertion. During power-up, MR remains inactive until VCC exceeds 1.0V, preventing spurious resets during supply ramp-up.
Is MAX6713SEXS+T10 pin-compatible with other members of the MAX6711/MAX6712/MAX6713 family, and what are the key functional differences?
Yes, MAX6713SEXS+T10 shares identical SC70-4 pinout and footprint with all MAX6711/MAX6712/MAX6713 variants. Key functional differences include reset threshold voltage (2.93V for 'S' suffix), output type (open-drain vs. push-pull in MAX6711/MAX6712), and reset polarity (active-low only). No PCB changes are needed when substituting within the same suffix group.
