Analog Devices Inc. ADM6713RAKS-REEL7

Overview

ADM6713RAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, designed to monitor 2.5 V power supplies with a precision reset threshold of 2.63 V (typ), 140 ms minimum reset timeout, open-drain active-low RESET output, and debounced manual reset input - used for reliable power-up/power-down sequencing in portable microcontroller systems.

For engineers reviewing the ADM6713RAKS-REEL7 datasheet, ADM6713RAKS-REEL7 pinout, ADM6713RAKS-REEL7 application, or ADM6713RAKS-REEL7 equivalent, key selection criteria include supply voltage monitoring accuracy over −40°C to +125°C, low 12 μA quiescent current, glitch-immune MR input, open-drain output flexibility, and SC70 footprint compatibility for space-constrained designs.

Technical Context

The ADM6713RAKS-REEL7 implements a precision bandgap-based voltage reference and comparator to assert RESET when VCC falls below 2.63 V (typ), with ±0.05 V threshold tolerance over temperature and 30 ppm/°C drift. Its internal debounce logic rejects MR pulses shorter than 100 ns while guaranteeing response to ≥1 μs pulses.

RESET remains active for ≥140 ms after VCC rises above threshold, with typical 240 ms timeout; the open-drain output supports pull-up to voltages higher than VCC, enabling level-shifting across logic families. Power supply glitch immunity is validated up to 1000 mV overdrive with transient rejection per Figure 9.

FAQ

What is the exact reset threshold voltage of ADM6713RAKS-REEL7 at 25°C?

The ADM6713RAKS-REEL7 has a nominal reset threshold voltage of 2.63 V at 25°C, with a guaranteed range of 2.59 V to 2.66 V. This value is factory-trimmed and specified across the full operating temperature range of −40°C to +125°C, making ADM6713RAKS-REEL7 suitable for precise 2.5 V supply supervision where margin against brownout is critical.

Does ADM6713RAKS-REEL7 support manual reset functionality, and how is it implemented?

Yes, ADM6713RAKS-REEL7 includes a dedicated debounced manual reset (MR) input on Pin 3. It accepts active-low pulses ≥1 μs in width and rejects transients <100 ns, eliminating need for external RC filtering. When asserted, MR forces RESET low for 240 ms (typical) after release - a feature confirmed in the functional block diagram and Table 4 of the Rev. B datasheet for ADM6713RAKS-REEL7.

What is the recommended pull-up resistor value for the open-drain RESET output of ADM6713RAKS-REEL7?

Analog Devices does not specify a single pull-up resistor value for ADM6713RAKS-REEL7, as the choice depends on system voltage, speed, and bus loading. Typical values range from 10 kΩ to 100 kΩ. The open-drain output can sink ≥1.2 mA at 0.3 V (for R/S/T/Z variants), allowing direct interface to 1.8 V, 3.3 V, or 5 V logic families - a key advantage of ADM6713RAKS-REEL7 over push-pull alternatives.

Can ADM6713RAKS-REEL7 operate reliably below 1.8 V supply voltage?

Yes, ADM6713RAKS-REEL7 is fully specified down to 1.0 V VCC and asserts RESET down to 1 V, with guaranteed operation across −40°C to +125°C. Its internal reference remains stable at low VCC, and the RESET output maintains valid logic levels even during deep brownout - a capability explicitly documented in the General Description and Absolute Maximum Ratings sections for ADM6713RAKS-REEL7.

Is ADM6713RAKS-REEL7 RoHS compliant and what packaging format is supplied?

Yes, ADM6713RAKS-REEL7 is RoHS compliant (denoted by "Z" suffix in ordering guide variants) and supplied in tape-and-reel format per the "REEL7" designation - meaning 3,000 units per reel. The device uses a Pb-free, halogen-free 4-lead SC70 (KS-4) package with JEDEC-standard dimensions and moisture sensitivity level (MSL) 1 rating.
