Analog Devices Inc. ADM6713RAKS-REEL

Overview

ADM6713RAKS-REEL from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, designed to monitor 2.5 V supply rails with a precision reset threshold of 2.63 V (typ), 140 ms minimum reset timeout, open-drain RESET output, and manual reset input. It asserts reset down to 1 V VCC and consumes only 12 μA typical supply current, enabling reliable power-on/power-down sequencing in space-constrained portable systems.

For engineers reviewing the ADM6713RAKS-REEL datasheet, ADM6713RAKS-REEL pinout, ADM6713RAKS-REEL application, or ADM6713RAKS-REEL equivalent, key selection criteria include its −40°C to +125°C operating range, SC70 footprint compatibility, open-drain output flexibility for mixed-voltage logic interfacing, and immunity to sub-100 ns supply glitches.

Technical Context

The ADM6713RAKS-REEL integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, debounced manual reset input (1 μs min pulse width, 100 ns glitch rejection), and internal reset timer generating ≥140 ms active-low assertion after VCC rise or MR activation. Its open-drain RESET output supports external pull-up to voltages exceeding VCC, enabling level-shifting across logic families.

Reset assertion occurs when VCC falls below 2.63 V (typ) and remains active for 240 ms (typ) after VCC recovers above threshold. The device operates from 1.0 V to 5.5 V supply, maintains valid reset down to VCC = 1 V, and features power supply glitch immunity up to 1000 mV overdrive with transient rejection per Figure 9.

FAQ

What is the exact reset threshold voltage of the ADM6713RAKS-REEL?

The ADM6713RAKS-REEL has a nominal reset threshold of 2.63 V at 25°C, with guaranteed range of 2.55 V to 2.70 V over −40°C to +85°C and 2.52 V to 2.74 V over 85°C to 125°C. This precise threshold is optimized for reliable supervision of 2.5 V power rails in industrial and automotive applications where tight voltage margins are critical.

Does the ADM6713RAKS-REEL require an external pull-up resistor on the RESET pin?

Yes, the ADM6713RAKS-REEL features an open-drain RESET output and requires an external pull-up resistor to establish a defined logic-high level. The resistor may connect to VCC or a higher voltage rail (e.g., 3.3 V or 5 V), enabling level-shifted reset signaling - a key design advantage not available with push-pull alternatives like the ADM6711 series.

What is the minimum pulse width accepted by the manual reset (MR) input of the ADM6713RAKS-REEL?

The ADM6713RAKS-REEL MR input accepts active-low pulses with minimum width of 1 μs and rejects transients shorter than 100 ns (typical). This built-in debounce eliminates need for external RC filtering in most designs, simplifying push-button integration and improving noise immunity in electrically hostile environments.

Can the ADM6713RAKS-REEL operate reliably at VCC = 1.0 V?

Yes, the ADM6713RAKS-REEL is fully specified to operate down to VCC = 1.0 V, with guaranteed reset assertion and functional MR input behavior. Its ability to assert valid RESET down to 1 V supports brownout detection in ultra-low-voltage systems and ensures safe shutdown before supply collapse.

What package type and dimensions does the ADM6713RAKS-REEL use?

The ADM6713RAKS-REEL uses a 4-lead SC70 (KS-4) package measuring 2.2 mm × 1.35 mm × 0.9 mm with 0.65 mm pin pitch. Its compact footprint and RoHS-compliant lead-free construction make it ideal for high-density PCB layouts in portable and automotive electronics where board space and thermal performance are constrained.
