Analog Devices Inc. ADM6384YKS31D2Z-R7

Overview

ADM6384YKS31D2Z-R7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision power supply monitoring with 3.08 V reset threshold, 20 ms minimum reset timeout, push-pull active-low RESET output, and manual reset (MR) input. It ensures reliable system initialization in brownout conditions for embedded controllers operating from 1 V to 5.5 V supply.

For engineers reviewing the ADM6384YKS31D2Z-R7 datasheet, ADM6384YKS31D2Z-R7 pinout, ADM6384YKS31D2Z-R7 application, or ADM6384YKS31D2Z-R7 equivalent, key selection criteria include guaranteed reset validity down to VCC = 1 V, internal 52 kΩ MR pull-up, glitch immunity against ≤100 ns transients, and operation across −40°C to +125°C.

Technical Context

The ADM6384YKS31D2Z-R7 implements a precision voltage comparator with hysteresis (2 × VTH) and temperature-compensated reference (60 ppm/°C), enabling stable reset assertion during VCC ramp-up and brownout. Its internal debounce logic filters MR input pulses ≥1 µs and rejects noise spikes <100 ns.

Reset timing is governed by a fixed timeout period (20 ms min) after VCC rises above 3.08 V or MR transitions high; the push-pull output drives low with VOL ≤ 0.3 V at ISINK = 80 µA (VCC ≥ 1 V), ensuring compatibility with TTL and CMOS inputs across its full operating range.

FAQ

What is the exact reset threshold voltage for ADM6384YKS31D2Z-R7?

The ADM6384YKS31D2Z-R7 has a nominal reset threshold of 3.08 V, with a guaranteed range of 3.00 V to 3.15 V at TA = 25°C. This value is factory-trimmed and specified over the full −40°C to +125°C operating temperature range with a temperature coefficient of 60 ppm/°C, ensuring predictable brownout behavior in automotive and industrial environments.

Does ADM6384YKS31D2Z-R7 support manual reset functionality?

Yes, ADM6384YKS31D2Z-R7 includes a dedicated MR (manual reset) input (Pin 3) that is active-low and features an internal 52 kΩ pull-up resistor. Driving MR low for ≥1 µs asserts the RESET output, and the device maintains reset for the full 20 ms timeout period after MR returns high - enabling reliable push-button or logic-controlled system reset without external components.

What is the minimum VCC level at which ADM6384YKS31D2Z-R7 guarantees valid RESET output?

The ADM6384YKS31D2Z-R7 guarantees valid active-low RESET output down to VCC = 1 V. At this voltage, the output sinks ≥80 µA while maintaining VOL ≤ 0.3 V, ensuring compatibility with microcontrollers and logic devices that require defined reset states during deep brownout conditions.

What package type and dimensions does ADM6384YKS31D2Z-R7 use?

ADM6384YKS31D2Z-R7 uses a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.95 mm. Its small outline and low profile enable high-density PCB layouts in portable and automotive electronics, and it complies with RoHS Directive 2011/65/EU as indicated by the "Z" suffix in the part number.

How does ADM6384YKS31D2Z-R7 handle power supply transients?

The ADM6384YKS31D2Z-R7 incorporates built-in glitch rejection circuitry that ignores fast negative-going VCC transients ≤100 ns in duration. For example, with its 3.08 V threshold, a 100 mV dip lasting ≤8 µs typically does not trigger reset - preventing false resets caused by switching noise or load transients while maintaining responsiveness to genuine brownout events.
