Product details
Overview
MAX6713ZEXS+T from Maxim Integrated is a precision microprocessor supervisory circuit with open-drain active-low RESET output, designed to monitor +2.5V power supplies in embedded systems. It asserts reset when VCC falls below 2.32V (±0.03V at +25°C), guarantees valid reset down to VCC = +1V, and delivers ≥140ms reset timeout after power-up or manual reset deassertion. Used in battery-powered instrumentation and critical µP systems requiring low supply current (12µA typical) and high noise immunity.
For engineers reviewing the MAX6713ZEXS+T datasheet, MAX6713ZEXS+T pinout, MAX6713ZEXS+T application, or MAX6713ZEXS+T equivalent, key selection criteria include its Z-suffix 2.32V reset threshold, SC70-4 open-drain output architecture, guaranteed operation from -40°C to +125°C, and compatibility with manual reset pushbuttons without external debounce.
Technical Context
The MAX6713ZEXS+T implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to maintain tight reset threshold accuracy across temperature. Its internal 20kΩ MR pull-up resistor enables direct switch-to-ground connection for manual reset, with 1µs minimum pulse width and 100ns glitch immunity.
Reset assertion is latched and held for ≥140ms after VCC rises above 2.32V or MR returns high; the open-drain RESET output supports level-shifting up to +6.0V via external pull-up and remains functional down to VCC = +1V, where it transitions to high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32V ±0.03V at +25°C; ensures reliable brownout detection before µP operational failure at +2.5V supply. |
| Supply Current | 12µA typical at VCC = +2.5V, TA = -40°C to +85°C; enables multi-year battery life in portable equipment. |
| Reset Timeout | 140–460ms over temperature; guarantees sufficient µP initialization time after power stabilization. |
| VCC Operating Range | +1.0V to +5.5V; allows supervision of low-voltage logic while maintaining reset validity down to 1V. |
| MR Input Threshold | VIL = 0.3×VCC, VIH = 0.7×VCC; compatible with TTL/CMOS logic and open-drain drivers without level shifters. |
| RESET Output Type | Open-drain with ≤1µA leakage when deasserted; supports bidirectional µP reset pins and multi-supply level shifting. |
| Package | 4-pin SC70 (X4-1 outline); 1.25mm × 0.85mm footprint ideal for space-constrained portable designs. |
Pinout & Package
MAX6713ZEXS+T is housed in a lead-free 4-pin SC70 package (outline X4-1, land pattern 90-0187), measuring 1.25mm × 0.85mm × 0.55mm, optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Return path for all internal circuitry; must be connected directly to system ground plane for noise immunity. |
| 2 RESET | Open-drain active-low reset output | Drives low during reset; requires external pull-up (to 0–6V) for logic-high state; interfaces with bidirectional µP reset I/O. |
| 3 MR | Manual reset input (active-low) | Internally pulled up to VCC (20kΩ typ); assert by grounding via momentary switch; no external debounce needed. |
| 4 VCC | Supply voltage input | Monitored +2.5V supply rail; powers internal circuitry and sets MR logic thresholds; operates from +1.0V to +5.5V. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.32V reset threshold | Guaranteed ±30mV tolerance at +25°C and ±0.07V over -40°C to +105°C; eliminates need for external trimming. |
| 140ms min reset timeout | Ensures µP completes internal initialization before release; holds reset even if VCC dips briefly during startup. |
| 12µA supply current | Reduces quiescent power in always-on monitoring circuits; extends battery life in handheld instruments. |
| VCC = +1V reset validity | RESET remains asserted until VCC rises above 2.32V, then stays low ≥140ms - functional even as supply collapses. |
| SC70-4 package | 0.65mm pitch, 1.25mm × 0.85mm body; saves >60% board area vs. SOT-23 while maintaining thermal performance. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6713TEXS+T | 3.08V reset threshold (vs. 2.32V); identical SC70-4 package, open-drain output, and timing specs. | Designed for +3.3V systems; not suitable for 2.5V monitoring without risk of late reset assertion. | Select only when supervising 3.3V rails; verify VTH alignment with target supply nominal and tolerance. |
| TPS3123E18DBVR | 1.8V fixed reset threshold; SOT-23-5 package; 1.8µA ICC; no manual reset input. | Lacks MR pin and open-drain flexibility; intended for ultra-low-power ASIC reset, not general-purpose µP supervision. | Use where minimal current dominates and manual reset is unnecessary; not drop-in due to pin count and function mismatch. |
Compared with MAX6713ZEXS+T, the MAX6713TEXS+T shifts reset activation to higher voltage (3.08V), making it unsuitable for 2.5V systems, while the TPS3123E18DBVR sacrifices MR functionality and output flexibility to achieve lower ICC - neither offers pin-compatible replacement without schematic or layout changes.

FAQ
What is the exact reset threshold voltage for MAX6713ZEXS+T and how does it vary with temperature?
The MAX6713ZEXS+T has a nominal reset threshold of 2.32V at +25°C, with guaranteed limits of 2.25V to 2.38V over -40°C to +85°C and 2.21V to 2.45V over +85°C to +105°C. Its 30ppm/°C tempco ensures predictable drift, enabling robust brownout detection in 2.5V systems across full industrial temperature range.
Does MAX6713ZEXS+T require an external pull-up resistor on the RESET pin, and what voltage can it tolerate?
Yes, MAX6713ZEXS+T requires an external pull-up resistor on the RESET pin because it features an open-drain output. The pull-up may connect to any voltage between 0V and +6.0V - including supplies higher than VCC - enabling level-shifting for interfacing with µPs powered by different rails.
Can MAX6713ZEXS+T operate reliably when VCC drops below 1.0V, and what happens to the RESET output?
MAX6713ZEXS+T guarantees valid reset assertion down to VCC = +1.0V. Below 1.0V, the RESET output transitions to high-impedance (open-circuit) - it stops sinking current. To maintain defined logic low in such cases, a pull-down resistor (e.g., 100kΩ to GND) is recommended per Maxim's application guidance.
How is manual reset implemented on MAX6713ZEXS+T, and does it need external components?
MAX6713ZEXS+T includes an internal 20kΩ pull-up resistor on the MR pin, so a simple normally-open momentary switch from MR to GND provides full manual reset functionality. No external resistors or debounce circuitry are required, though a 0.1µF capacitor from MR to GND adds noise immunity in EMI-prone environments.
What package type and dimensions does MAX6713ZEXS+T use, and is it RoHS-compliant?
MAX6713ZEXS+T uses a lead-free 4-pin SC70 package (outline X4-1), measuring 1.25mm × 0.85mm × 0.55mm with 0.65mm pin pitch. The "+T" suffix confirms RoHS compliance and green packaging; land pattern 90-0187 is specified for PCB layout.
