Analog Devices Inc. ADM6711ZAKS-REEL7

Overview

ADM6711ZAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset generation for 2.5 V supply monitoring with 2.32 V threshold, 140 ms minimum reset timeout, push-pull active-low RESET output, and manual reset input. It ensures reliable power-up sequencing in portable microcontroller systems.

For engineers reviewing the ADM6711ZAKS-REEL7 datasheet, ADM6711ZAKS-REEL7 pinout, ADM6711ZAKS-REEL7 application, or ADM6711ZAKS-REEL7 equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, low 12 μA quiescent current, glitch immunity to 100 ns transients, and compatibility with brownout detection in space-constrained embedded designs.

Technical Context

The ADM6711ZAKS-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, debounced manual reset input (1 μs minimum pulse width), and internal 240 ms typical reset assertion timer. Its reset generator asserts RESET low during power-up until VCC exceeds 2.32 V and remains asserted for ≥140 ms after threshold crossing.

Designed for single-supply operation from 1.0 V to 5.5 V, it maintains valid reset assertion down to 1 V VCC and features power supply glitch immunity via internal filtering-rejecting transients ≤100 ns while responding reliably to longer supply dips. The push-pull output eliminates need for external pull-up components.

FAQ

What is the exact reset threshold voltage of ADM6711ZAKS-REEL7 at 25°C?

The ADM6711ZAKS-REEL7 has a nominal reset threshold of 2.32 V at 25°C, with a typical range of 2.28 V to 2.35 V. This value is specified in Table 1 of the Rev. B datasheet and is optimized for monitoring 2.5 V power supplies within standard ±4% tolerance bands. The ADM6711ZAKS-REEL7 maintains this accuracy across its full operating temperature range.

Does ADM6711ZAKS-REEL7 support manual reset functionality, and how is it implemented?

Yes, ADM6711ZAKS-REEL7 includes a debounced manual reset (MR) input on Pin 3. It is an active-low input that ignores transients shorter than 100 ns and guarantees recognition of pulses ≥1 μs. When asserted, MR forces RESET low for 240 ms (typical) after release. No external RC network is needed-the debounce is fully integrated, simplifying design and improving reliability in noisy environments.

What is the minimum supply voltage at which ADM6711ZAKS-REEL7 continues to assert a valid RESET signal?

The ADM6711ZAKS-REEL7 asserts a valid active-low RESET signal down to VCC = 1.0 V, as confirmed by Absolute Maximum Ratings and functional specifications. Below 1.0 V, the device may cease operation-but crucially, it maintains correct reset behavior throughout the entire 1.0 V to 5.5 V operating range, including during brownout conditions common in battery-powered systems.

How does the push-pull output of ADM6711ZAKS-REEL7 differ from open-drain alternatives like ADM6713ZAKS-REEL7?

The ADM6711ZAKS-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, ADM6713ZAKS-REEL7 uses an open-drain output requiring a pull-up to define the high state. This makes ADM6711ZAKS-REEL7 ideal for direct interface with MCUs lacking internal pull-ups and reduces component count in compact designs.

Is ADM6711ZAKS-REEL7 RoHS compliant, and what does the 'Z' suffix indicate in its part number?

Yes, ADM6711ZAKS-REEL7 is RoHS compliant-the 'Z' in the part number explicitly denotes RoHS-compliant packaging per the Ordering Guide footnote. The 'AKS' indicates 4-lead SC70 (KS-4) package, '-REEL7' specifies 3 k unit reel quantity, and 'Z' confirms lead-free, halogen-free construction meeting EU Directive 2011/65/EU requirements.
