Analog Devices Inc. ADM6713ZAKSZ-REEL7

Overview

ADM6713ZAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing open-drain active-low RESET output with 2.32 V reset threshold, 140 ms minimum timeout, and operation down to 1.0 V VCC. It monitors 2.5 V supply rails in portable embedded systems requiring low-power (12 μA typical) and temperature-stable (−40°C to +125°C) power-on reset functionality.

For engineers reviewing the ADM6713ZAKSZ-REEL7 datasheet, ADM6713ZAKSZ-REEL7 pinout, ADM6713ZAKSZ-REEL7 application, or ADM6713ZAKSZ-REEL7 equivalent, key selection criteria include reset threshold accuracy over temperature, manual reset debounce timing, open-drain output flexibility for mixed-voltage logic interfacing, and SC70 footprint compatibility in space-constrained designs.

Technical Context

The ADM6713ZAKSZ-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and debounced manual reset input with 100 ns glitch immunity and ≥1 μs pulse acceptance. Its reset generator asserts RESET low during power-up until VCC exceeds 2.32 V (typ), then holds active for 140–460 ms depending on temperature.

As an open-drain variant, it requires an external pull-up resistor-enabling RESET to interface with logic supplies higher than VCC-and maintains valid output down to VCC = 1.0 V, with leakage current ≤1 μA when deasserted. The device achieves power supply glitch immunity up to 1000 mV overdrive with transient rejection <100 ns.

FAQ

What is the exact reset threshold voltage of ADM6713ZAKSZ-REEL7 at room temperature?

The ADM6713ZAKSZ-REEL7 has a nominal reset threshold of 2.32 V at 25°C, with a specified range of 2.28 V to 2.35 V. This value is factory-trimmed and guaranteed across production lots, enabling precise supervision of 2.5 V power rails without external calibration. The ADM6713ZAKSZ-REEL7 maintains this accuracy with ±0.05 V variation over −40°C to +85°C ambient conditions.

Does ADM6713ZAKSZ-REEL7 support manual reset functionality, and how is it implemented?

Yes, ADM6713ZAKSZ-REEL7 includes a dedicated MR (manual reset) pin (Pin 3) that accepts active-low logic signals or mechanical switch inputs. It features built-in debounce with guaranteed recognition of pulses ≥1 μs and rejection of transients <100 ns. When MR is pulled low, ADM6713ZAKSZ-REEL7 asserts RESET for 240 ms after MR returns high-ensuring clean system-level reset without external timing components.

What package type and dimensions does ADM6713ZAKSZ-REEL7 use, and is it compatible with standard reflow profiles?

ADM6713ZAKSZ-REEL7 uses the 4-lead SC70 (KS-4) package, measuring 2.20 mm × 1.35 mm × 0.9 mm with 0.65 mm lead pitch. It complies with JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for standard Pb-free reflow profiles (peak temperature 260°C). The SC70 footprint is pin-compatible with other KS-4 devices, simplifying layout reuse in space-constrained designs.

How does the open-drain output of ADM6713ZAKSZ-REEL7 differ from push-pull alternatives like ADM6711ZAKSZ-REEL7?

The ADM6713ZAKSZ-REEL7 features an open-drain RESET output requiring an external pull-up resistor, allowing the RESET signal to interface with logic supplies higher than its monitored VCC (e.g., pulling RESET to 3.3 V while supervising a 2.5 V rail). In contrast, ADM6711ZAKSZ-REEL7 uses a push-pull output that drives high to ~0.8×VCC-limiting interoperability with mixed-voltage systems unless level shifters are added.

What is the minimum VCC voltage at which ADM6713ZAKSZ-REEL7 continues to assert a valid RESET signal?

ADM6713ZAKSZ-REEL7 guarantees RESET assertion down to VCC = 1.0 V, with full functionality-including threshold comparison and MR response-maintained across the entire 1.0 V to 5.5 V operating range. Below 0.8 V, the output enters high-impedance state; a 100 kΩ pull-down resistor is recommended to prevent floating logic levels in deep brownout scenarios involving ADM6713ZAKSZ-REEL7.
