Analog Devices Inc. ADM6384YKS26D3-RL7

Overview

ADM6384YKS26D3-RL7 from Analog Devices is a precision microprocessor supervisory circuit in a 4-lead SC70 package, monitoring VCC with a 2.63 V reset threshold and 140 ms minimum reset timeout. It features push-pull active-low RESET output valid down to VCC = 1 V, manual reset input with 52 kΩ internal pull-up, and consumes only 4–7 µA at 1.8–2.5 V. It is used in portable microcontroller systems requiring reliable brownout detection and system initialization.

For engineers reviewing the ADM6384YKS26D3-RL7 datasheet, ADM6384YKS26D3-RL7 pinout, ADM6384YKS26D3-RL7 application, or ADM6384YKS26D3-RL7 equivalent, key selection criteria include reset threshold accuracy (±20 mV), temperature coefficient (60 ppm/°C), glitch immunity against sub-100 ns transients, and guaranteed operation across −40°C to +125°C.

Technical Context

The ADM6384YKS26D3-RL7 implements a precision voltage comparator with hysteresis (2 × VTH) and integrated debounce logic for both power-on and manual reset events. Its reset generator uses a fixed-time delay circuit with four selectable timeout options - this variant selects the 140 ms minimum period (D3 suffix).

It operates across 1 V to 5.5 V supply range and guarantees valid RESET assertion even as VCC falls to 1 V, enabled by a robust push-pull output stage capable of sinking 80 µA at 1 V and up to 3.2 mA at 4.5 V. The MR input accepts logic-level or push-button signals with 1 µs minimum pulse width and rejects noise spikes under 100 ns.

FAQ

What is the exact reset threshold voltage range for ADM6384YKS26D3-RL7?

The ADM6384YKS26D3-RL7 has a guaranteed reset threshold range of 2.56 V (minimum) to 2.69 V (maximum) at 25°C, with 60 ppm/°C temperature coefficient. This corresponds to the "26" threshold code in the ordering nomenclature and is validated per Table 1 of the Rev. E datasheet.

Does ADM6384YKS26D3-RL7 support manual reset, and what are its electrical requirements?

Yes, ADM6384YKS26D3-RL7 includes an active-low manual reset (MR) input with 52 kΩ internal pull-up. It requires a minimum 1 µs low pulse width, accepts VIL ≤ 0.3 × VCC (or ≤0.8 V when VCC > 4 V), and rejects transients under 100 ns - enabling direct push-button use without external RC networks.

What is the reset timeout duration for ADM6384YKS26D3-RL7, and how is it specified?

The ADM6384YKS26D3-RL7 features a D3-coded reset timeout of 140 ms minimum (up to 280 ms maximum). This is the guaranteed minimum assertion time after VCC rises above threshold or after MR returns high - critical for ensuring full microcontroller initialization before release.

Can ADM6384YKS26D3-RL7 operate reliably at VCC = 1.2 V, and what is its reset output behavior?

Yes, ADM6384YKS26D3-RL7 guarantees valid active-low RESET output down to VCC = 1 V. At 1.2 V, it can sink ≥80 µA while maintaining VOL ≤ 0.3 V, ensuring compatible logic-level reset signaling to modern ultra-low-voltage MCUs such as ARM Cortex-M23 or RISC-V cores.

What package type and dimensions does ADM6384YKS26D3-RL7 use, and is it RoHS-compliant?

ADM6384YKS26D3-RL7 uses the 4-lead SC70 (KS-4) package: 2.2 mm × 1.35 mm × 0.9 mm body, 0.65 mm lead pitch, and coplanarity ≤ 0.10 mm. The "-RL7" suffix denotes a 3,000-piece RoHS-compliant tape-and-reel shipment per JEDEC standard.
