Analog Devices Inc. ADM6713MAKSZ-REEL7

Overview

ADM6713MAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing open-drain active-low RESET output with 2.63 V reset threshold, 140 ms minimum timeout, and operation down to 1.0 V VCC. It monitors 3 V supply rails in embedded controllers and portable systems requiring low-power (12 μA typical) brownout protection.

For engineers reviewing the ADM6713MAKSZ-REEL7 datasheet, ADM6713MAKSZ-REEL7 pinout, ADM6713MAKSZ-REEL7 application, or ADM6713MAKSZ-REEL7 equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, manual reset debounce timing, open-drain output flexibility for mixed-voltage logic interfacing, and SC70 footprint compatibility in space-constrained designs.

Technical Context

The ADM6713MAKSZ-REEL7 implements a precision bandgap voltage reference with 30 ppm/°C temperature coefficient and internal comparator monitoring VCC against a fixed 2.63 V threshold (typical at 25°C, 2.55–2.70 V over −40°C to +85°C). Its reset generator asserts RESET low during power-up, brownout, or manual reset, holding it active for ≥140 ms after VCC exceeds threshold.

It features a debounced manual reset (MR) input rejecting <100 ns glitches and guaranteeing response to ≥1 μs pulses, plus power supply glitch immunity validated up to 1000 mV overdrive. The open-drain RESET output supports external pull-up to voltages higher than VCC, enabling level-shifting across logic families.

FAQ

What is the exact reset threshold voltage of ADM6713MAKSZ-REEL7 and how does it vary with temperature?

The ADM6713MAKSZ-REEL7 has a nominal reset threshold of 2.63 V at 25°C, with guaranteed range of 2.55 V to 2.70 V over −40°C to +85°C and 2.52 V to 2.74 V over 85°C to +125°C. Its temperature coefficient is 30 ppm/°C, meaning threshold drift is tightly bounded and predictable across its full operating range - critical for stable 3 V rail supervision in automotive and industrial environments where ADM6713MAKSZ-REEL7 is deployed.

Does ADM6713MAKSZ-REEL7 support manual reset, and what are the timing requirements?

Yes, ADM6713MAKSZ-REEL7 includes a dedicated MR (manual reset) pin that accepts active-low signals. It guarantees recognition of input pulses ≥1 μs in width and rejects transients <100 ns, providing robust debouncing without external components. When MR is pulled low, ADM6713MAKSZ-REEL7 asserts RESET for 240 ms (typical) after MR returns high - a timing profile confirmed in the functional block diagram and specifications table for ADM6713MAKSZ-REEL7.

What is the output configuration of ADM6713MAKSZ-REEL7 and why does it matter for system design?

ADM6713MAKSZ-REEL7 features an open-drain RESET output, unlike the push-pull variant ADM6711. This requires an external pull-up resistor but enables critical design flexibility: the pull-up can connect to a voltage higher than VCC (e.g., 5 V or 3.3 V) to interface with different logic families. This capability is explicitly documented in the ADM6713 functional diagram and "Circuit Description" section, making ADM6713MAKSZ-REEL7 ideal for mixed-voltage systems where the monitored supply (3 V) differs from the target logic domain.

Can ADM6713MAKSZ-REEL7 operate reliably during severe supply brownouts?

Yes, ADM6713MAKSZ-REEL7 is specified to assert RESET down to VCC = 1.0 V and remains functional over a 1.0 V to 5.5 V supply range. Its internal reference and comparator continue accurate operation even as VCC collapses, ensuring no premature release from reset during deep brownouts. This behavior is verified in the Absolute Maximum Ratings and General Description sections of the ADM6713MAKSZ-REEL7 datasheet and distinguishes it from supervisors that cease functioning below ~1.8 V.

What package type and footprint does ADM6713MAKSZ-REEL7 use, and are there layout considerations?

ADM6713MAKSZ-REEL7 uses a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm with 0.65 mm lead pitch. Layout best practices include placing a 0.1 μF ceramic decoupling capacitor between VCC and GND as close as possible to the device, and adding a 0.1 μF capacitor from MR to GND if routed over long traces - both recommendations directly cited in the ADM6713MAKSZ-REEL7 datasheet's "Circuit Description" and "Power Supply Glitch Immunity" sections to ensure robust operation.
