Analog Devices Inc. ADM6384YKS17D3Z-R7

Overview

ADM6384YKS17D3Z-R7 from Analog Devices is a microprocessor supervisory circuit in a 4-lead SC70 package that monitors VCC supply voltage and asserts an active-low reset signal when voltage falls below 1.67 V threshold. It provides 140 ms minimum reset timeout, manual reset input with 52 kΩ internal pull-up, guaranteed reset validity down to VCC = 1 V, and consumes only 4–7 µA at 1.8–2.5 V. It is used in portable microcontroller systems requiring reliable power-on and brownout reset.

For engineers reviewing the ADM6384YKS17D3Z-R7 datasheet, ADM6384YKS17D3Z-R7 pinout, ADM6384YKS17D3Z-R7 application, or ADM6384YKS17D3Z-R7 equivalent, key selection criteria include reset threshold accuracy (±30 mV), temperature coefficient (60 ppm/°C), glitch immunity (100 ns MR rejection), push-pull output drive capability (up to 3.2 mA sink), and operation across −40°C to +125°C.

Technical Context

The ADM6384YKS17D3Z-R7 implements precision voltage monitoring using an internal bandgap reference and comparator with hysteresis (2 × VTH). Its reset generator includes a fixed-time delay circuit for the 140 ms timeout (D3 variant), independent of VCC level or temperature drift.

It integrates debounced manual reset logic with 1 µs minimum pulse width requirement and 200 ns MR-to-reset propagation delay. The push-pull RESET output ensures fast, low-impedance assertion without external pull-up, supporting valid logic levels even as VCC drops to 1 V.

FAQ

What is the exact reset threshold voltage of the ADM6384YKS17D3Z-R7?

The ADM6384YKS17D3Z-R7 has a nominal reset threshold of 1.67 V, with a guaranteed range of 1.62 V to 1.71 V at TA = 25°C. This value is factory-trimmed and specified over the full −40°C to +125°C operating range, with a temperature coefficient of 60 ppm/°C. The ADM6384YKS17D3Z-R7 uses this precise threshold to detect brownout conditions on 1.8 V supply rails.

Does the ADM6384YKS17D3Z-R7 require an external pull-up resistor on the RESET pin?

No, the ADM6384YKS17D3Z-R7 features a push-pull RESET output stage that actively drives low and high states without external components. It can sink up to 3.2 mA at VCC ≥ 4.5 V and source current when deasserted. Unlike open-drain supervisors, the ADM6384YKS17D3Z-R7 eliminates the need for an external pull-up resistor, reducing BOM count and PCB area.

How does the manual reset (MR) input behave on the ADM6384YKS17D3Z-R7?

The MR input on the ADM6384YKS17D3Z-R7 is active-low with a 52 kΩ internal pull-up resistor, ensuring a defined high state when unconnected. Driving MR low for ≥1 µs asserts RESET, and the output remains asserted for the full 140 ms timeout period after MR returns high. The ADM6384YKS17D3Z-R7 also rejects noise pulses shorter than 100 ns, providing robust switch debounce.

Can the ADM6384YKS17D3Z-R7 operate reliably at VCC = 1.0 V?

Yes, the ADM6384YKS17D3Z-R7 guarantees valid RESET output behavior down to VCC = 1.0 V, including proper logic-level assertion and timing. Its internal circuitry remains functional and the push-pull output maintains specified VOL (≤0.3 V at 80 µA sink) even at this minimum supply. This capability makes the ADM6384YKS17D3Z-R7 suitable for deep brownout recovery in ultra-low-voltage systems.

What package type and dimensions does the ADM6384YKS17D3Z-R7 use?

The ADM6384YKS17D3Z-R7 uses a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.9 mm, with 0.65 mm pin pitch. This compact outline matches EIAJ SC82 standards and is optimized for high-density PCB layouts in portable and automotive electronics. The ADM6384YKS17D3Z-R7's SC70 footprint enables drop-in replacement for other 4-pin supervisory ICs in space-constrained designs.
