Analog Devices Inc. ADM6711LAKSZ-REEL7

Overview

ADM6711LAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset generation for 5 V supply monitoring with 4.63 V threshold, 140 ms minimum active timeout, push-pull RESET output, and operation down to 1.0 V VCC. It ensures reliable power-up sequencing in embedded controllers and automotive ECUs.

For engineers reviewing the ADM6711LAKSZ-REEL7 datasheet, ADM6711LAKSZ-REEL7 pinout, ADM6711LAKSZ-REEL7 application, or ADM6711LAKSZ-REEL7 equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, low 12 μA quiescent current, manual reset debounce timing, glitch immunity against 100 ns transients, and compatibility with space-constrained portable designs requiring SC70 footprint.

Technical Context

The ADM6711LAKSZ-REEL7 integrates a precision voltage reference, comparator, and 240 ms typical reset timeout timer. Its reset assertion remains active until VCC exceeds 4.63 V (typ) and sustains for ≥140 ms after crossing threshold, ensuring stable power rail establishment before microprocessor release.

It features a debounced manual reset (MR) input rejecting <100 ns glitches and accepting ≥1 μs pulses, with internal pull-up resistance of 10–20 kΩ. The push-pull RESET output drives logic directly without external components, sinking up to 1.2 mA at 0.3 V while VCC > 1.0 V.

FAQ

What is the exact reset threshold voltage of ADM6711LAKSZ-REEL7 and how does it vary with temperature?

The ADM6711LAKSZ-REEL7 has a nominal reset threshold of 4.63 V at 25°C, with a guaranteed range of 4.50 V to 4.75 V over −40°C to +85°C and 4.44 V to 4.82 V over 85°C to +125°C. Its temperature coefficient is 30 ppm/°C, resulting in ≤±0.15 V total deviation across the full −40°C to +125°C range - confirmed in Table 1 and Figure 8 of the Rev. B datasheet.

Does ADM6711LAKSZ-REEL7 support manual reset functionality, and what are its timing requirements?

Yes, ADM6711LAKSZ-REEL7 includes a debounced manual reset (MR) input. It rejects negative-going pulses shorter than 100 ns (typical) and reliably accepts pulses ≥1 μs in width. When MR is asserted low, RESET remains low and stays active for 240 ms (typical) after MR returns high - detailed in Pin Function Descriptions (Table 4) and Circuit Description (Page 8).

What is the minimum supply voltage at which ADM6711LAKSZ-REEL7 can assert a valid RESET signal?

ADM6711LAKSZ-REEL7 asserts RESET down to VCC = 1.0 V, as specified in the Absolute Maximum Ratings (Table 2) and General Description. Below 0.8 V, the output enters high-impedance state; however, the device continues asserting low until VCC drops below 1.0 V - enabling fail-safe operation during deep brownouts.

Is ADM6711LAKSZ-REEL7 RoHS compliant and what packaging format does it use?

Yes, ADM6711LAKSZ-REEL7 is RoHS compliant (indicated by the "Z" suffix per Ordering Guide footnote), supplied in tape-and-reel format (REEL7 = 3 k unit reel), and packaged in a 4-lead SC70 (KS-4) outline measuring 2.20 mm × 1.35 mm - verified in the Ordering Guide (Page 9) and Outline Dimensions (Figure 11).

How does the push-pull RESET output of ADM6711LAKSZ-REEL7 differ from open-drain alternatives like ADM6713?

The ADM6711LAKSZ-REEL7 features a push-pull RESET output that actively drives both high and low states, eliminating the need for an external pull-up resistor. In contrast, ADM6713 uses an open-drain output requiring external pull-up. This makes ADM6711LAKSZ-REEL7 ideal for simplified BOMs and direct interfacing with standard CMOS inputs - confirmed in Features, Functional Block Diagrams, and Figure 3.
