Analog Devices Inc. ADM6384YKS23D3Z-R7

Overview

ADM6384YKS23D3Z-R7 from Analog Devices is a precision microprocessor supervisory circuit in a 4-lead SC70 package, monitoring VCC with a fixed 2.31 V reset threshold, 140 ms minimum reset timeout, and guaranteed active-low push-pull RESET output valid down to VCC = 1 V. It supports manual reset via MR input and consumes only 4–7 µA at 1.8–2.5 V, making it suitable for low-power portable microcontroller systems requiring brownout protection.

For engineers reviewing the ADM6384YKS23D3Z-R7 datasheet, ADM6384YKS23D3Z-R7 pinout, ADM6384YKS23D3Z-R7 application, or ADM6384YKS23D3Z-R7 equivalent, key selection criteria include reset threshold accuracy (±2.37 V typ), temperature coefficient (60 ppm/°C), glitch immunity against sub-100 ns transients, and compatibility with wide VCC range (1–5.5 V) in automotive-grade −40°C to +125°C operation.

Technical Context

The ADM6384YKS23D3Z-R7 implements a precision bandgap-based voltage reference with internal hysteresis (2 × VTH) and a debounced manual reset input featuring 52 kΩ internal pull-up. Its reset generator uses analog timing to guarantee ≥140 ms assertion after VCC rise or MR release.

It delivers push-pull RESET output with VOL ≤ 0.3 V at ISINK = 80 µA (VCC ≥ 1 V), enabling direct interface with CMOS inputs without external pull-ups. The device rejects fast VCC transients-e.g., 100 mV overdrive below VTH for up to ~8 µs-without false triggering.

FAQ

What is the exact reset threshold voltage of ADM6384YKS23D3Z-R7?

The ADM6384YKS23D3Z-R7 has a nominal reset threshold of 2.31 V, with a typical tolerance of ±0.06 V (2.25 V to 2.37 V) over −40°C to +125°C. This value is factory-trimmed and specified in Table 1 of the Rev. E datasheet under "ADM6384x23x" row. It is designed to reliably supervise 2.5 V rails during brownout conditions without false triggering.

Does ADM6384YKS23D3Z-R7 support manual reset functionality?

Yes, ADM6384YKS23D3Z-R7 includes an active-low manual reset input (MR, Pin 3) that asserts RESET when pulled low for ≥1 µs. It features an internal 52 kΩ pull-up resistor and on-chip debounce, allowing direct connection to a push-button switch without external components. MR-to-RESET delay is 200 ns, and it rejects glitches <100 ns.

What is the minimum VCC level at which ADM6384YKS23D3Z-R7 guarantees valid RESET output?

ADM6384YKS23D3Z-R7 guarantees valid active-low RESET output down to VCC = 1 V, as confirmed in the "RESET OUTPUT VOLTAGE" section (VOL ≤ 0.3 V at ISINK = 80 µA, VCC ≥ 1.0 V). This ensures fail-safe behavior during severe brownout-unlike many competitors that cease operation below 1.5 V.

What package type and dimensions does ADM6384YKS23D3Z-R7 use?

ADM6384YKS23D3Z-R7 uses a 4-lead SC70 package (package code KS-4), measuring 2.20 mm × 1.35 mm × 0.9 mm with 0.65 mm lead pitch. Per Figure 14 in the datasheet, it conforms fully to EIAJ SC82 except for pin 2 width, and is RoHS-compliant (Z suffix).

How does ADM6384YKS23D3Z-R7 handle power supply transients?

ADM6384YKS23D3Z-R7 incorporates built-in glitch rejection: it ignores VCC transients ≤100 ns and tolerates short dips based on overdrive magnitude (e.g., a 100 mV dip below 2.31 V lasting ≤8 µs typically avoids reset). An optional 0.1 µF bypass capacitor on VCC further enhances immunity, as detailed in Figure 10 and Applications Information.
