Product details
Overview
ADM6384YKS23D3-RL7 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.
For engineers reviewing the ADM6384YKS23D3-RL7 datasheet, ADM6384YKS23D3-RL7 pinout, ADM6384YKS23D3-RL7 application, or ADM6384YKS23D3-RL7 equivalent, key selection criteria include reset threshold accuracy (±20 mV), glitch immunity against sub-100 ns transients, temperature-stable hysteresis (2 × VTH), and operation across −40°C to +125°C industrial range.
Technical Context
The ADM6384YKS23D3-RL7 implements a precision voltage comparator with internal reference and debounced manual reset logic. Its reset generator uses a fixed-time monostable circuit triggered by VCC crossing 2.31 V or MR assertion, with built-in hysteresis (4.62 mV) and temperature coefficient of 60 ppm/°C.
It features a push-pull RESET output capable of sinking 3.2 mA at 4.5 V while maintaining VOL ≤ 0.4 V, and an MR input with 52 kΩ internal pull-up, 1 µs minimum pulse width, and 100 ns glitch rejection - enabling robust integration into noisy embedded power rails without external RC filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.31 V (typ), ±20 mV tolerance - ensures reliable brownout detection for 2.5 V systems with margin. |
| Reset Timeout | 140 ms (min), 280 ms (max) - provides sufficient hold time for microcontroller initialization after power stabilization. |
| Supply Current | 4 µA (typ) at 1.8 V - enables multi-year battery life in always-on portable instrumentation. |
| Operating Temp | −40°C to +125°C - qualified for under-hood automotive, industrial PLC, and high-reliability edge nodes. |
| VCC Range | 1 V to 5.5 V - supports reset assertion even during deep brownout or partial power loss. |
| RESET Output | Active-low push-pull, VOL ≤ 0.4 V @ 3.2 mA - directly drives standard CMOS reset inputs without pull-up resistor. |
| MR Input | Internal 52 kΩ pull-up, 1 µs min pulse, 100 ns glitch rejection - allows direct connection to momentary switch or FPGA GPIO. |
Pinout & Package
ADM6384YKS23D3-RL7 is housed in a 4-lead SC70 (KS-4) package, 2.20 mm × 1.35 mm × 0.9 mm, with gull-wing leads and 0.65 mm pitch. Pin 1 (GND) is marked by a dot; device is RoHS-compliant and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground Reference | Primary return path for internal comparator, reset driver, and MR pull-up; must be low-impedance connection to system ground plane. |
| RESET (Pin 2) | Active-Low Reset Output | Push-pull output asserted low when VCC < 2.31 V or MR is pulled low; sinks up to 3.2 mA at 4.5 V with VOL ≤ 0.4 V. |
| MR (Pin 3) | Manual Reset Input | Active-low input with 52 kΩ internal pull-up; requires ≥1 µs low pulse to trigger reset; rejects transients <100 ns. |
| VCC (Pin 4) | Monitored Supply Voltage | Input for supply voltage supervision; device operates and asserts valid RESET down to VCC = 1 V. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Reset Threshold | 2.31 V with ±20 mV tolerance and 60 ppm/°C drift - eliminates need for external trimming in 2.5 V rail monitoring. |
| Fixed 140 ms Timeout | Guaranteed minimum assertion period ensures full microcontroller boot sequence completion before deassertion. |
| Push-Pull RESET Output | No external pull-up required; drives standard CMOS reset inputs directly and maintains logic low down to VCC = 1 V. |
| Integrated MR Debounce | On-chip timing and noise rejection eliminate need for external RC filter or firmware debounce on manual reset line. |
| Ultra-Low Quiescent Current | 4 µA at 1.8 V - extends battery life in portable medical sensors and wireless IoT endpoints without compromising supervision integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6384TTT+T | 2.32 V threshold, 140 ms timeout, SOT23-4 package, 10 µA typical ICC | Higher supply current reduces battery lifetime in ultra-low-power designs; same functional timing but less thermal stability (100 ppm/°C) | Select when legacy MAXIM footprint compatibility is required and higher ICC is acceptable. |
| TPS3808G33DBVR | 3.3 V fixed threshold, 200 ms timeout, 1.6 µA ICC, SOT23-5 package | Not pin-compatible; requires PCB redesign; lacks MR input; optimized for 3.3 V systems only | Choose only if system uses 3.3 V rail and lowest possible ICC is critical; not a drop-in replacement. |
Compared with MAX6384TTT+T and TPS3808G33DBVR, the ADM6384YKS23D3-RL7 offers superior low-voltage operation (valid RESET to 1 V), lower ICC at 1.8 V, tighter threshold tolerance, and integrated MR debounce - making it optimal for 2.5 V industrial and portable systems where reliability and power efficiency are co-prioritized.

FAQ
What is the exact reset threshold voltage of the ADM6384YKS23D3-RL7?
The ADM6384YKS23D3-RL7 has a nominal reset threshold of 2.31 V, with a guaranteed range of 2.26 V to 2.37 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.
Does the ADM6384YKS23D3-RL7 require an external pull-up resistor on the RESET pin?
No, the ADM6384YKS23D3-RL7 features a push-pull RESET output stage and does not require an external pull-up resistor. It actively drives low and high states, delivering VOL ≤ 0.4 V at 3.2 mA sink current and VOH ≥ 0.8 × VCC when sourcing 500–800 µA.
Can the ADM6384YKS23D3-RL7 operate reliably during cold-crank conditions in automotive applications?
Yes, the ADM6384YKS23D3-RL7 is rated for −40°C to +125°C and guarantees valid RESET output down to VCC = 1 V - enabling robust reset assertion during automotive cold-crank events where battery voltage may dip below 6 V and regulated 2.5 V rails collapse transiently.
What is the minimum pulse width required on the MR pin to trigger a reset on the ADM6384YKS23D3-RL7?
The ADM6384YKS23D3-RL7 requires a minimum 1 µs low pulse on the MR pin to initiate a reset. The internal debounce circuit rejects transients shorter than 100 ns, and the MR input includes a 52 kΩ internal pull-up, allowing direct connection to a momentary switch without external components.
How does the ADM6384YKS23D3-RL7 handle fast power supply transients?
The ADM6384YKS23D3-RL7 incorporates dedicated glitch rejection circuitry that ignores VCC transients shorter than 100 ns. As shown in Figure 10 of the datasheet, it tolerates defined combinations of magnitude and duration - e.g., a 100 mV dip below 2.31 V lasting ≤8 µs will not cause spurious reset assertion.
