Product details
Overview
ADM6384YKS29D1-RL7 from Analog Devices is a precision microprocessor supervisory circuit in 4-lead SC70 package, monitoring VCC with 2.93 V reset threshold, 1 ms minimum reset timeout, and active-low push-pull RESET output. It guarantees valid reset assertion down to VCC = 1 V and consumes only 4–6 µA at 1.8–2.5 V, enabling use in battery-powered portable equipment and automotive control modules.
For engineers reviewing the ADM6384YKS29D1-RL7 datasheet, ADM6384YKS29D1-RL7 pinout, ADM6384YKS29D1-RL7 application, or ADM6384YKS29D1-RL7 equivalent, key selection criteria include reset threshold accuracy (±20 mV), MR input glitch rejection (100 ns), guaranteed reset validity at low VCC, and SC70 footprint compatibility for space-constrained embedded designs.
Technical Context
The ADM6384YKS29D1-RL7 implements a precision voltage comparator with internal 52 kΩ MR pull-up and on-chip debounce logic. Its reset generator uses a fixed-time delay circuit triggered by either VCC falling below 2.93 V or MR assertion, with reset deassertion delayed by exactly 1 ms after recovery.
It features power supply glitch immunity via transient rejection circuitry validated for 100 mV overdrive and sub-10 µs transients, and operates across −40°C to +125°C with 60 ppm/°C reset threshold temperature coefficient - critical for under-hood automotive and industrial controller applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6384TTUT+T | 2.93 V threshold, 1 ms timeout, SOT-23-5 package (5-pin), higher 10 µA ICC | Requires external pull-up for open-drain RESET; larger footprint than SC70 | Select when SOT-23-5 is already standardized in design and MR debouncing is handled externally |
| TPS3808G18DBVR | 1.8 V threshold (not 2.93 V), 20 ms default timeout, adjustable via capacitor, SC70-5 | Not drop-in: different threshold, longer timeout, extra capacitor pin; requires layout change | Choose only if system requires programmable timeout and lower threshold; not suitable for direct replacement |
Compared with MAX6384TTUT+T and TPS3808G18DBVR, the ADM6384YKS29D1-RL7 offers the only SC70-4 solution with factory-trimmed 2.93 V threshold and guaranteed 1 ms timeout - delivering smallest footprint and highest threshold accuracy for 3.0 V rail supervision without design compromises.

FAQ
What is the exact reset threshold voltage of ADM6384YKS29D1-RL7?
The ADM6384YKS29D1-RL7 has a nominal reset threshold of 2.93 V, with a guaranteed range of 2.85 V to 3.00 V at TA = 25°C. This value is factory-trimmed and specified across the full −40°C to +125°C operating temperature range with 60 ppm/°C drift, making it suitable for precise 3.0 V rail supervision in automotive and industrial applications where margin is critical.
Does ADM6384YKS29D1-RL7 require an external pull-up resistor on the RESET pin?
No, ADM6384YKS29D1-RL7 does not require an external pull-up resistor because its RESET output is push-pull active-low. The internal driver can sink up to 3.2 mA at 4.5 V, allowing direct connection to standard microcontroller reset inputs without additional components - reducing BOM cost and PCB area versus open-drain alternatives.
What is the minimum pulse width required on the MR pin of ADM6384YKS29D1-RL7?
The ADM6384YKS29D1-RL7 requires a minimum 1 µs low pulse on the MR pin to initiate a reset. This specification is guaranteed across −40°C to +125°C and enables reliable triggering from mechanical push buttons, GPIO outputs, or logic gates without external timing circuits or Schmitt triggers.
Can ADM6384YKS29D1-RL7 operate reliably at VCC = 1.2 V?
Yes, ADM6384YKS29D1-RL7 guarantees valid RESET output assertion down to VCC = 1 V, including at 1.2 V. Its internal circuitry remains fully functional and the reset signal remains asserted as long as VCC stays below 2.93 V - a key capability for fail-safe operation during severe brownout conditions in battery-backed systems.
What package type and dimensions does ADM6384YKS29D1-RL7 use?
ADM6384YKS29D1-RL7 uses the 4-lead SC70 (KS-4) package: 2.2 mm × 1.35 mm body size, 0.65 mm lead pitch, and 0.9 mm maximum height. This compact outline occupies ~40% less area than SOT-23-5, enabling high-density routing in space-limited applications such as wearable medical devices and automotive body control modules.
