Analog Devices Inc. ADM6713LAKSZ-REEL7

Overview

ADM6713LAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing open-drain active-low RESET output with 4.63 V threshold, 140 ms minimum reset timeout, and operation down to 1.0 V VCC. It monitors 5 V power supplies in embedded microprocessor systems requiring reliable power-on reset and brownout protection.

For engineers reviewing the ADM6713LAKSZ-REEL7 datasheet, ADM6713LAKSZ-REEL7 pinout, ADM6713LAKSZ-REEL7 application, or ADM6713LAKSZ-REEL7 equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, manual reset debounce timing, supply current under 30 μA at 3.6 V, and open-drain output compatibility with mixed-voltage logic interfaces.

Technical Context

The ADM6713LAKSZ-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and 240 ms typical reset timeout generator. Its internal debouncer rejects MR pulses shorter than 100 ns while guaranteeing response to ≥1 μs low pulses.

Designed for high-noise immunity, it withstands transients up to 1000 mV overdrive without false triggering and supports valid RESET assertion down to VCC = 1 V. The open-drain RESET output allows pull-up to voltages exceeding VCC, enabling interface with higher-voltage logic families.

FAQ

What is the reset threshold voltage of ADM6713LAKSZ-REEL7 and how does it vary with temperature?

The ADM6713LAKSZ-REEL7 has a nominal reset threshold of 4.63 V, with tolerance of ±0.07 V at 25°C. Over the full operating range of −40°C to +85°C, the threshold varies between 4.50 V and 4.75 V, and from 4.44 V to 4.82 V at 85°C to +125°C. This 30 ppm/°C temperature coefficient ensures stable 5 V supply supervision without calibration.

Does ADM6713LAKSZ-REEL7 support manual reset, and what are its timing requirements?

Yes, ADM6713LAKSZ-REEL7 includes a dedicated MR pin that accepts active-low manual reset signals. It features hardware debounce rejecting pulses shorter than 100 ns and guarantees recognition of any low pulse ≥1 μs. When asserted, MR forces RESET low and holds it for 240 ms after MR returns high - eliminating need for external timing components or firmware handling.

What is the function of the open-drain RESET output in ADM6713LAKSZ-REEL7?

The open-drain RESET output in ADM6713LAKSZ-REEL7 requires an external pull-up resistor, allowing the RESET signal to interface with logic systems operating at voltages higher than VCC. This enables direct connection to 3.3 V, 5 V, or even 12 V logic families without level shifters, while maintaining compatibility with the monitored 5 V supply.

Can ADM6713LAKSZ-REEL7 operate reliably during severe supply brownouts?

Yes, ADM6713LAKSZ-REEL7 asserts RESET down to VCC = 1.0 V and remains functional through deep brownouts. Its internal circuitry continues monitoring and asserting RESET until VCC rises above 4.63 V and sustains for ≥140 ms. This behavior prevents premature MCU release during marginal supply conditions common in automotive and industrial settings.

What package type and dimensions does ADM6713LAKSZ-REEL7 use?

ADM6713LAKSZ-REEL7 uses the 4-lead SC70 (KS-4) package, with body dimensions of 2.20 mm × 1.35 mm × 0.9 mm and 0.65 mm lead pitch. Its small footprint and low profile make it ideal for dense PCB layouts in portable and automotive electronics where board space is constrained.
