Analog Devices Inc. ADM6711LAKS-REEL7

Overview

ADM6711LAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset generation for 4.63 V supply monitoring with push-pull active-low RESET output, 140 ms minimum timeout, and operation down to 1.0 V VCC. It features manual reset debouncing, power supply glitch immunity, and low 12 μA quiescent current-used in automotive microcontroller power sequencing.

For engineers reviewing the ADM6711LAKS-REEL7 datasheet, ADM6711LAKS-REEL7 pinout, ADM6711LAKS-REEL7 application, or ADM6711LAKS-REEL7 equivalent, key selection criteria include reset threshold accuracy (±3% over −40°C to +125°C), SC70 footprint compatibility, push-pull drive capability eliminating external pull-up, and guaranteed reset assertion during brownout below 4.50 V.

Technical Context

The ADM6711LAKS-REEL7 integrates a precision voltage reference, comparator, and 240 ms typical reset timeout timer. Its reset assertion remains active until VCC exceeds 4.50 V (min) across full temperature range and sustains low state for ≥140 ms after threshold crossing.

It accepts a debounced manual reset input (MR) with 1 μs minimum pulse width and rejects transients <100 ns. The push-pull RESET output drives logic directly with 0.3 V max low-level voltage at 1.2 mA sink, supporting direct interface to CMOS microcontrollers without external components.

FAQ

What is the reset threshold voltage of ADM6711LAKS-REEL7 and how does it vary with temperature?

The ADM6711LAKS-REEL7 has a nominal reset threshold of 4.63 V, specified from 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, meaning threshold drift is tightly bounded-critical for maintaining reliable 5 V system supervision across automotive and industrial thermal profiles. This behavior is confirmed in Table 1 and Figure 8 of the ADM6711/ADM6713 Rev. B datasheet.

Does ADM6711LAKS-REEL7 require an external pull-up resistor on the RESET pin?

No, ADM6711LAKS-REEL7 does not require an external pull-up resistor because it features a push-pull RESET output. Unlike the open-drain ADM6713 variants, the ADM6711LAKS-REEL7 actively drives both high and low states: RESET goes low when VCC is below threshold or MR is asserted, and rises to ~0.8×VCC when released. This eliminates external components and simplifies PCB layout-confirmed in the Functional Block Diagram (Figure 1) and General Description section.

What is the minimum pulse width required on the MR pin of ADM6711LAKS-REEL7 to trigger a reset?

The MR pin of ADM6711LAKS-REEL7 requires a minimum pulse width of 1 μs to guarantee recognition, as specified in Table 1 under "Manual Reset (MR)" test conditions. Pulses shorter than 100 ns are rejected due to built-in debounce circuitry. This ensures noise immunity while remaining compatible with standard GPIO toggling or mechanical switch actuation-detailed in the Manual Reset Input section (Page 8) and Pin Function Descriptions (Page 6).

Can ADM6711LAKS-REEL7 operate reliably when VCC drops below 2.0 V?

Yes, ADM6711LAKS-REEL7 is fully specified to operate and assert RESET down to VCC = 1.0 V, per the "VCC Operating Voltage Range" parameter in Table 1. It maintains valid reset assertion even during deep brownout events, and its internal circuitry continues functioning reliably at 1.2 V minimum across −40°C to +125°C. This capability is explicitly called out in the General Description and Absolute Maximum Ratings sections of the datasheet.

What package type and dimensions does ADM6711LAKS-REEL7 use?

ADM6711LAKS-REEL7 uses the 4-lead SC70 package (package option KS-4), measuring 2.2 mm × 1.35 mm × 0.9 mm with 0.65 mm lead pitch. Its outline conforms fully to EIAJ SC82 except for pin 2 width, as shown in Figure 11. This compact footprint supports high-density PCB layouts in space-constrained applications like automotive sensors and portable medical devices-verified in the Ordering Guide and Outline Dimensions sections (Pages 9–10).
