Product details
Overview
ADM6384YKS29D1Z-R7 from Analog Devices is a precision microprocessor supervisory circuit in a 4-lead SC70 package, monitoring VCC with a 2.93 V reset threshold and 1 ms minimum reset timeout. It features push-pull active-low RESET output, manual reset (MR) input with internal 52 kΩ pull-up, and guaranteed valid reset assertion down to VCC = 1 V. It is used in portable embedded systems requiring low-power, high-temperature reliability.
For engineers reviewing the ADM6384YKS29D1Z-R7 datasheet, ADM6384YKS29D1Z-R7 pinout, ADM6384YKS29D1Z-R7 application, or ADM6384YKS29D1Z-R7 equivalent, key selection criteria include reset threshold accuracy (±2.7% at 2.93 V), glitch immunity against <100 ns transients, supply current of 4–7 µA at 1.8–2.5 V, and operation across −40°C to +125°C.
Technical Context
The ADM6384YKS29D1Z-R7 implements a voltage-monitoring comparator with built-in hysteresis (2 × VTH), debounced manual reset logic, and fixed-timing reset timeout generation. Its reset generator asserts RESET low when VCC falls below 2.93 V or MR is pulled low for ≥1 µs, holding RESET active for ≥1 ms after recovery.
It uses an internal bandgap reference and temperature-compensated threshold (60 ppm/°C), ensuring stable trip points over industrial and automotive temperature ranges. The push-pull output drives loads up to 3.2 mA at VCC ≥ 4.5 V while maintaining VOL ≤ 0.4 V, eliminating need for external pull-ups.
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 |
|---|---|---|---|
| MAX6384XR29D1+T | 2.93 V threshold, 1 ms timeout, SOT-23-4 package; higher ICC (12 µA typ at 3.3 V) | Same functional role but larger footprint and higher supply current limits use in ultra-low-power designs | Select if SOT-23-4 PCB land pattern exists and 12 µA ICC is acceptable |
| TPS3808G18DBVR | 1.8 V threshold (fixed), 20 ms timeout, SC70-5 package; requires external pull-up on open-drain RESET | Not interchangeable due to different threshold and open-drain output - needs redesign of reset interface | Choose only for new designs targeting 1.8 V rails; not a drop-in replacement for ADM6384YKS29D1Z-R7 |
Compared with MAX6384XR29D1+T and TPS3808G18DBVR, the ADM6384YKS29D1Z-R7 offers the lowest ICC in its class (4 µA at 1.8 V), push-pull RESET eliminating external components, and SC70-4 footprint - making it optimal for miniaturized, battery-sensitive applications where 2.93 V threshold alignment is required.

FAQ
What is the exact reset threshold voltage of the ADM6384YKS29D1Z-R7?
The ADM6384YKS29D1Z-R7 has a nominal reset threshold of 2.93 V, with a typical tolerance of ±2.7% (2.85 V to 3.00 V) over −40°C to +125°C. This value is confirmed in Table 1 of the Rev. E datasheet under "ADM6384x29x" row and applies specifically to this orderable variant.
Does the ADM6384YKS29D1Z-R7 require an external pull-up resistor on the RESET pin?
No, the ADM6384YKS29D1Z-R7 features a push-pull active-low RESET output, meaning it actively drives both high and low states. Unlike open-drain supervisors, it does not require an external pull-up resistor - simplifying design and reducing BOM cost.
What is the minimum pulse width required on the MR pin to trigger a reset in the ADM6384YKS29D1Z-R7?
The ADM6384YKS29D1Z-R7 requires a minimum MR input pulse width of 1 µs to reliably assert RESET. This specification is verified across temperature and voltage ranges and is documented in the "MR Input Pulse Width" row of Table 1 in the datasheet.
Can the ADM6384YKS29D1Z-R7 operate with supply voltages below 2.0 V?
Yes - the ADM6384YKS29D1Z-R7 operates from VCC = 1 V to 5.5 V. Its RESET output remains valid down to VCC = 1 V, and supply current drops to 3–4 µA at 1.8 V, enabling use in ultra-low-voltage battery systems such as coin-cell-powered devices.
Is the ADM6384YKS29D1Z-R7 RoHS compliant and lead-free?
Yes, the "Z" suffix in ADM6384YKS29D1Z-R7 explicitly denotes RoHS compliance per EU Directive 2011/65/EU. The device uses lead-free terminations and meets Analog Devices' Pb-Free standard, with soldering profile rated for 260°C (40 sec) for Pb-free reflow.
