Analog Devices Inc. ADM6713SAKSZ-REEL7

Overview

ADM6713SAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, featuring open-drain RESET output, 2.93 V reset threshold (±0.04 V at 25°C), 140–460 ms reset timeout, 12 μA supply current at VCC < 3.6 V, and operation from −40°C to +125°C. It monitors 3.3 V power supplies in embedded microcontroller systems requiring reliable power-on reset and manual reset capability.

For engineers reviewing the ADM6713SAKSZ-REEL7 datasheet, ADM6713SAKSZ-REEL7 pinout, ADM6713SAKSZ-REEL7 application, or ADM6713SAKSZ-REEL7 equivalent, this device delivers precision voltage supervision with glitch immunity, low-power operation, and manual reset debouncing - critical for automotive ECUs, portable instrumentation, and industrial controllers where supply stability and brownout resilience are mandatory.

Technical Context

The ADM6713SAKSZ-REEL7 implements a bandgap-based voltage reference and comparator architecture to assert RESET when VCC falls below 2.93 V (typical), with ±0.15 V tolerance over −40°C to +85°C. Its internal debounce logic rejects MR pulses shorter than 100 ns and guarantees response to ≥1 μs pulses.

It features open-drain RESET output requiring an external pull-up resistor, enabling level-shifting to voltages higher than VCC. Reset assertion remains active down to VCC = 1 V, and the device maintains immunity to transients up to 1000 mV overdrive with durations under 10 μs (depending on amplitude), per Figure 9.

FAQ

What is the exact reset threshold voltage of ADM6713SAKSZ-REEL7 and how does it vary with temperature?

The ADM6713SAKSZ-REEL7 has a nominal reset threshold of 2.93 V at 25°C, with guaranteed range of 2.85 V to 3.00 V over −40°C to +85°C and 2.81 V to 3.05 V over 85°C to +125°C. This 2.93 V threshold is selected to reliably supervise 3.3 V supplies while allowing for typical tolerance and droop, and its temperature coefficient is specified at 30 ppm/°C - ensuring predictable behavior across automotive and industrial operating conditions.

Does ADM6713SAKSZ-REEL7 require an external pull-up resistor on the RESET pin?

Yes, ADM6713SAKSZ-REEL7 features an open-drain RESET output and requires an external pull-up resistor to establish the logic-high level. The resistor may be connected to VCC or to a higher voltage rail (up to +6 V), enabling level translation. Typical values range from 10 kΩ to 100 kΩ depending on rise time and bus loading requirements - unlike the push-pull ADM6711 variant, which needs no external components.

What is the minimum pulse width accepted on the MR (manual reset) input of ADM6713SAKSZ-REEL7?

The MR input of ADM6713SAKSZ-REEL7 guarantees recognition of active-low pulses ≥1 μs in duration and rejects transients <100 ns (typical). This built-in hardware debounce eliminates the need for external RC filters, simplifying layout and improving reliability in noisy environments such as automotive or factory-floor applications where switch bounce or EMI could otherwise trigger spurious resets.

Can ADM6713SAKSZ-REEL7 operate with supply voltages below 2.93 V and still generate a valid RESET signal?

Yes - ADM6713SAKSZ-REEL7 asserts RESET down to VCC = 1.0 V and remains functional across a 1.0 V to 5.5 V supply range. When VCC drops below ~0.8 V, the internal output stage ceases sinking current; for guaranteed logic-low behavior near 0 V, a 100 kΩ pull-down resistor from RESET to GND is recommended per Figure 10 in the datasheet to prevent floating states during deep brownout or power removal.

What package type and RoHS status does ADM6713SAKSZ-REEL7 use?

ADM6713SAKSZ-REEL7 uses the 4-lead SC70 (KS-4) package - measuring 2.20 mm × 1.35 mm × 0.90 mm with 0.65 mm lead pitch - and is RoHS-compliant, as indicated by the "Z" suffix in the part number. The "REEL7" denotes tape-and-reel packaging with 3,000-unit reels, suitable for automated SMT assembly in high-volume production environments.
