Analog Devices Inc. ADM6713TAKS-REEL

Overview

ADM6713TAKS-REEL from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, designed to monitor 3.08 V supply rails with ±50 mV threshold accuracy over −40°C to +125°C. It provides open-drain active-low RESET output, 140–460 ms reset timeout, manual reset input with 1 μs minimum pulse width, and operates down to 1.0 V VCC. It is used in automotive engine control units for reliable power-on reset sequencing.

For engineers reviewing the ADM6713TAKS-REEL datasheet, ADM6713TAKS-REEL pinout, ADM6713TAKS-REEL application, or ADM6713TAKS-REEL equivalent, key selection criteria include reset threshold tolerance at temperature extremes, open-drain output compatibility with mixed-voltage logic, manual reset debounce timing, glitch immunity against sub-100 ns transients, and SC70 footprint constraints in space-constrained embedded designs.

Technical Context

The ADM6713TAKS-REEL implements a precision bandgap voltage reference with 30 ppm/°C temperature coefficient, feeding a comparator that asserts RESET when VCC falls below 3.08 V (typ) with hysteresis. Its internal debounce circuit rejects MR pulses shorter than 100 ns and guarantees response to ≥1 μs low-going edges.

RESET assertion persists for a minimum of 140 ms after VCC rises above threshold, with typical timeout of 240 ms - ensuring stable power rail establishment before microprocessor release. The open-drain output supports pull-up to voltages higher than VCC, enabling interface with 3.3 V or 5 V logic while powered from a 3.0 V rail.

FAQ

What is the exact reset threshold voltage of the ADM6713TAKS-REEL and how does it vary with temperature?

The ADM6713TAKS-REEL has a nominal reset threshold of 3.08 V at 25°C, with a guaranteed range of 3.00 V to 3.15 V over −40°C to +85°C and 2.95 V to 3.21 V over 85°C to +125°C. Its temperature coefficient is 30 ppm/°C, resulting in ≤±10 mV drift across the full operating range - sufficient for precise 3.0 V rail supervision without calibration.

Does the ADM6713TAKS-REEL support manual reset, and what are the timing requirements?

Yes, the ADM6713TAKS-REEL features a debounced manual reset (MR) input that accepts active-low pulses ≥1 μs in duration and rejects transients <100 ns. When MR is pulled low, RESET remains asserted for 240 ms (typical) after MR returns high - providing consistent, noise-immune reset initiation independent of power rail status.

What is the recommended pull-up resistor value for the open-drain RESET output of the ADM6713TAKS-REEL?

Analog Devices specifies no minimum pull-up resistance, but recommends values between 10 kΩ and 100 kΩ depending on rise time and bus loading. For standard 3.3 V logic interfacing, a 47 kΩ resistor is typical; for faster edges or higher noise immunity, 10 kΩ is used. The ADM6713TAKS-REEL RESET output can sink up to 1.2 mA at 0.3 V while VCC ≥ VTH min.

Can the ADM6713TAKS-REEL operate reliably during severe supply voltage droops?

Yes, the ADM6713TAKS-REEL asserts RESET down to 1.0 V VCC and maintains valid output states through brownout conditions. Its internal reference remains stable, and the open-drain RESET output continues sinking current until VCC drops below ~0.8 V - enabling clean system shutdown sequencing even during deep undervoltage events.

Is the ADM6713TAKS-REEL qualified for automotive applications, and what packaging does it use?

Yes, the ADM6713TAKS-REEL is rated for −40°C to +125°C operation and manufactured in Analog Devices' automotive-qualified process. It uses a 4-lead SC70 (KS-4) package with JEDEC-standard footprint and RoHS-compliant materials - meeting mechanical and thermal requirements for under-hood deployment in engine control and body electronics.
