Analog Devices Inc. ADM6713ZAKS-REEL7

Overview

ADM6713ZAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, featuring open-drain RESET output, 2.32 V reset threshold (typ), 140 ms minimum reset timeout, and operation down to 1.0 V VCC. It monitors 2.5 V supply rails in portable embedded systems requiring reliable power-on reset and brownout protection.

For engineers reviewing the ADM6713ZAKS-REEL7 datasheet, ADM6713ZAKS-REEL7 pinout, ADM6713ZAKS-REEL7 application, or ADM6713ZAKS-REEL7 equivalent, key selection criteria include reset threshold accuracy over temperature, manual reset debounce timing, low 12 μA quiescent current, and compatibility with 1.0–5.5 V supply domains in space-constrained designs.

Technical Context

The ADM6713ZAKS-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and debounced manual reset input with 1 μs minimum pulse width acceptance. Its reset generator asserts active-low RESET for ≥140 ms after VCC rises above 2.32 V (typ) and maintains assertion during VCC drops below threshold.

Unlike the push-pull ADM6711 variant, the ADM6713ZAKS-REEL7 uses an open-drain RESET output requiring an external pull-up resistor-enabling level-shifting to voltages higher than VCC-and supports valid reset signaling down to VCC = 0 V when paired with a 100 kΩ pull-down resistor.

FAQ

What is the reset threshold voltage of the ADM6713ZAKS-REEL7?

The ADM6713ZAKS-REEL7 has a nominal reset threshold of 2.32 V at 25°C, with a guaranteed range of 2.25 V to 2.38 V over −40°C to +85°C. This value is factory-trimmed and specified in Table 1 of the Rev. B datasheet. The threshold remains stable across temperature with a 30 ppm/°C coefficient, making ADM6713ZAKS-REEL7 suitable for precise monitoring of 2.5 V supply rails where margin against brownout is critical.

Does the ADM6713ZAKS-REEL7 support manual reset functionality?

Yes, the ADM6713ZAKS-REEL7 includes a dedicated MR (manual reset) pin (Pin 3) that accepts active-low signals. It features built-in debounce with guaranteed acceptance of pulses ≥1 μs and rejection of glitches <100 ns. When MR is pulled low, ADM6713ZAKS-REEL7 asserts RESET for 240 ms (typical) after MR returns high-ensuring complete system reset without external timing components.

What type of RESET output does the ADM6713ZAKS-REEL7 provide?

The ADM6713ZAKS-REEL7 provides an open-drain RESET output (Pin 2), unlike the push-pull version in the ADM6711 family. This requires an external pull-up resistor, which can be connected to any voltage up to 6 V-even higher than VCC-enabling flexible interfacing with diverse logic families. The output sinks up to 1.2 mA at 0.3 V while asserted, ensuring solid low-level drive into standard CMOS inputs.

Can the ADM6713ZAKS-REEL7 operate with supply voltages below 2.5 V?

Yes, the ADM6713ZAKS-REEL7 operates over a VCC range of 1.0 V to 5.5 V and asserts RESET down to VCC = 1.0 V. Its internal circuitry remains functional and accurate even at 1.0 V, allowing reliable brownout detection during deep undervoltage events. For operation down to VCC = 0 V, a 100 kΩ pull-down resistor on the RESET line is recommended to prevent floating states, as documented in Figure 10 of the datasheet.

What package and lead count does the ADM6713ZAKS-REEL7 use?

The ADM6713ZAKS-REEL7 is packaged in a 4-lead SC70 (KS-4) outline, measuring 2.20 mm × 1.35 mm × 0.9 mm. This RoHS-compliant, surface-mount package supports high-density PCB layouts and standard reflow soldering processes. Pin configuration is GND (1), RESET (2), MR (3), and VCC (4), as shown in Figure 4 of the Rev. B datasheet.
