Analog Devices Inc. ADM6711TAKS-REEL7

Overview

ADM6711TAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, designed to monitor 3.08 V power supplies with ±50 mV threshold tolerance over −40°C to +125°C, provide push-pull active-low RESET output, and assert reset for ≥140 ms after VCC rise. It supports manual reset input with 1 μs minimum pulse width and operates down to 1.0 V VCC.

For engineers reviewing the ADM6711TAKS-REEL7 datasheet, ADM6711TAKS-REEL7 pinout, ADM6711TAKS-REEL7 application, or ADM6711TAKS-REEL7 equivalent, key selection criteria include reset threshold accuracy at temperature extremes, low 12 μA supply current, glitch immunity against 100 ns transients, and compatibility with 3.3 V microprocessor systems requiring reliable power-on reset sequencing.

Technical Context

The ADM6711TAKS-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and a 240 ms typical reset timeout generator. Its internal debounce logic rejects MR pulses shorter than 100 ns while guaranteeing response to ≥1 μs low-going signals.

It features push-pull RESET output capable of sinking 1.2 mA at 0.3 V (for R/S/T/Z variants) and sourcing 500–800 μA at 0.8×VCC, eliminating need for external pull-up resistors. Reset assertion remains valid down to VCC = 1.0 V, and the device maintains immunity to fast supply glitches up to 1000 mV overdrive.

FAQ

What is the exact reset threshold voltage of ADM6711TAKS-REEL7 and how does it vary with temperature?

The ADM6711TAKS-REEL7 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. This 3.08 V specification targets reliable supervision of 3.3 V power rails, allowing margin for regulator dropout and noise. The device uses a trimmed bandgap reference with 30 ppm/°C temperature coefficient to maintain accuracy across its full operating range.

Does ADM6711TAKS-REEL7 support manual reset functionality, and what are the electrical requirements?

Yes, ADM6711TAKS-REEL7 includes a debounced manual reset (MR) input. It accepts active-low pulses ≥1 μs in duration and rejects transients <100 ns. The MR input threshold is defined as V_IL ≤ 0.3×V_CC and V_IH ≥ 0.7×V_CC. When MR is pulled low, RESET asserts immediately and remains low for 240 ms (typical) after MR returns high. No external RC network is required - the debounce is fully integrated.

What is the supply current consumption of ADM6711TAKS-REEL7 across its operating voltage and temperature range?

ADM6711TAKS-REEL7 draws 12 μA typical supply current when V_CC < 3.6 V and operating from −40°C to +85°C. At 85°C to +125°C, current increases to 60 μA maximum. Over the full V_CC range of 1.0 V to 5.5 V, current remains below 35 μA at room temperature. This ultra-low quiescent current enables multi-year battery life in always-on portable and sensor applications.

How does ADM6711TAKS-REEL7 handle power supply transients, and what is its glitch immunity specification?

ADM6711TAKS-REEL7 provides robust power supply glitch immunity: it ignores negative-going transients on V_CC shorter than 100 ns (typical), and Figure 9 in the datasheet confirms immunity to transients up to 1000 mV amplitude depending on duration. Internal filtering ensures no false reset occurs due to EMI, switching noise, or load-dump events - a key requirement for automotive and industrial deployments.

Is ADM6711TAKS-REEL7 pin-compatible with other members of the ADM6711/ADM6713 family, and what output type does it feature?

Yes, ADM6711TAKS-REEL7 shares identical 4-lead SC70 (KS-4) pinout with all ADM6711 and ADM6713 variants: Pin 1 = GND, Pin 2 = RESET, Pin 3 = MR, Pin 4 = V_CC. It features a push-pull RESET output - unlike ADM6713 variants which use open-drain - enabling direct interface to CMOS/TTL inputs without external pull-up resistors. This simplifies design and improves noise immunity.
