Product details
Overview
ADM6713LAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, featuring open-drain RESET output, 4.63 V reset threshold (−40°C to +125°C), 140 ms minimum reset timeout, 12 μA typical supply current, and manual reset input with 1 μs minimum pulse width-used for reliable power-up sequencing in embedded microcontroller systems.
For engineers reviewing the ADM6713LAKSZ-REEL datasheet, ADM6713LAKSZ-REEL pinout, ADM6713LAKSZ-REEL application, or ADM6713LAKSZ-REEL equivalent, key selection criteria include reset threshold accuracy over temperature, open-drain output compatibility with mixed-voltage logic, glitch immunity against fast transients, and SC70 footprint constraints in space-constrained portable designs.
Technical Context
The ADM6713LAKSZ-REEL implements a precision bandgap voltage reference and comparator-based reset generator with internal debounce on the MR input. Its reset assertion remains active until VCC rises above 4.63 V (typ) and sustains low for ≥140 ms after threshold crossing.
It features open-drain RESET output requiring external pull-up, enabling level-shifting to voltages higher than VCC; manual reset is debounced to reject <100 ns glitches and guarantees response to ≥1 μs pulses, with reset holding low for 240 ms (typ) after MR release.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (typ) at 25°C; ±0.15 V over −40°C to +85°C - ensures reliable detection of 5 V supply brownout before microprocessor corruption. |
| Reset Timeout | 140–460 ms (min–max) - provides sufficient hold time for power rail stabilization and CPU core initialization. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V, −40°C to +85°C - enables battery-backed operation in always-on monitoring applications. |
| Operating Range | 1.2 V to 5.5 V (−40°C to +125°C) - supports valid reset assertion down to 1 V VCC and full functionality across industrial temperature range. |
| MR Input Pulse Width | ≥1 μs guaranteed acceptance - allows robust manual reset triggering via mechanical switches or digital logic without external timing components. |
| Glitch Immunity | Rejects transients <100 ns - prevents spurious resets during ESD events or switching noise on VCC line. |
| Output Type | Open-drain RESET - permits flexible pull-up to 5.5 V, enabling interface with 1.8 V, 3.3 V, or 5 V logic families. |
Pinout & Package
ADM6713LAKSZ-REEL uses a 4-lead SC70 (KS-4) package: 2.2 mm × 1.35 mm × 0.9 mm body, 0.65 mm lead pitch, coplanarity ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | 0 V return path for all internal circuitry; must be connected directly to system ground plane for stable threshold reference. |
| 2 RESET | Active-low open-drain output | Sinks current when asserted; requires external pull-up resistor to define logic-high level and drive strength for downstream logic. |
| 3 MR | Active-low manual reset input | Debounced input accepting ≥1 μs pulses; floating by default; tied low to force reset independent of VCC status. |
| 4 VCC | Monitored supply voltage input | Input for 1.2–5.5 V supply being supervised; also powers internal circuitry; reset asserts when VCC falls below 4.63 V (typ). |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 4.63 V ±0.15 V over −40°C to +85°C - eliminates need for external trimming in 5 V system supervision. |
| Ultra-low quiescent current | 12 μA typical - extends battery life in portable instrumentation and remote sensors. |
| Open-drain RESET output | Supports pull-up to 5.5 V - enables direct interfacing with mixed-voltage FPGA I/O banks or legacy 5 V peripherals. |
| Manual reset debounce | 100 ns glitch rejection + 1 μs minimum pulse guarantee - removes need for external RC filter or Schmitt trigger. |
| Power supply glitch immunity | Immune to transients <100 ns - maintains system reliability in electrically noisy automotive or industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326US46D3+T | 4.63 V threshold, push-pull output, 3 μA max supply current, SOT-23-3 package | Lacks manual reset input; no MR pin - unsuitable where field-service reset is required | Select when lowest possible quiescent current is critical and manual reset is unnecessary. |
| TPS3808G33DBVR | 3.3 V threshold (not 4.63 V), open-drain output, 16 μA typical supply current, SOT-23-5 package | Higher pin count; includes watchdog timer not present in ADM6713LAKSZ-REEL | Choose only if 3.3 V supply supervision is needed and watchdog functionality adds value. |
Compared with MAX6326US46D3+T and TPS3808G33DBVR, ADM6713LAKSZ-REEL uniquely combines 4.63 V threshold, manual reset input, open-drain output, and SC70 footprint - making it the only option among the three that satisfies simultaneous requirements for 5 V system supervision, field-reset capability, and ultra-compact layout.

FAQ
What is the reset threshold voltage of the ADM6713LAKSZ-REEL?
The ADM6713LAKSZ-REEL has a nominal reset threshold of 4.63 V at 25°C, with tolerance of ±0.15 V over the −40°C to +85°C operating range and ±0.24 V over −40°C to +125°C. This threshold is factory-trimmed and specified in the Ordering Guide and Table 1 of the Rev. B datasheet.
Does the ADM6713LAKSZ-REEL require an external pull-up resistor on the RESET pin?
Yes, the ADM6713LAKSZ-REEL features an open-drain RESET output and requires an external pull-up resistor. The resistor may be connected to VCC or to any other logic-compatible voltage up to 5.5 V, enabling level-shifting flexibility not available with push-pull alternatives like the ADM6711 series.
What is the minimum pulse width accepted on the MR pin of the ADM6713LAKSZ-REEL?
The ADM6713LAKSZ-REEL accepts manual reset pulses as short as 1 μs (guaranteed), with internal debounce rejecting transients shorter than 100 ns. This allows direct connection to mechanical switches without external filtering, and ensures robust operation in electrically noisy environments.
Can the ADM6713LAKSZ-REEL operate with supply voltages below 2.5 V?
Yes - the ADM6713LAKSZ-REEL operates from 1.2 V to 5.5 V over its full −40°C to +125°C temperature range. It asserts RESET down to 1 V VCC, making it functional even during deep brownout conditions where other supervisors may lose regulation.
Is the ADM6713LAKSZ-REEL RoHS compliant?
Yes, the "Z" suffix in ADM6713LAKSZ-REEL explicitly denotes RoHS compliance per the Ordering Guide footnote: "Z = RoHS Compliant Part." It meets EU Directive 2011/65/EU and is lead-free with NiPdAu terminal finish.
