Product details
Overview
MAX6384XS23D6 from Maxim Integrated is a low-power microprocessor supervisory circuit with active-low push-pull reset output, factory-set 2.31V reset threshold (±2.5% over –40°C to +125°C), 560ms minimum VCC reset timeout, and debounced manual reset input (MR) with internal 63kΩ pullup. It monitors single-supply systems in battery-powered instrumentation and embedded controllers requiring reliable power-on reset and brownout protection.
For engineers reviewing the MAX6384XS23D6 datasheet, MAX6384XS23D6 pinout, MAX6384XS23D6 application, or MAX6384XS23D6 equivalent, this page delivers verified electrical parameters, SC70-4 package mapping, MR timing behavior, reset assertion guarantees down to VCC = 1V, and direct alternatives for supply-chain continuity and design flexibility.
Technical Context
The MAX6384XS23D6 implements a precision bandgap-based voltage comparator with ±2.5% threshold accuracy across –40°C to +125°C and a temperature-compensated internal timer that guarantees ≥560ms reset assertion after VCC rises above 2.31V. Its MR input features glitch rejection (100ns) and 1µs minimum pulse width support, with reset deassertion delayed by tRP after MR release.
This device uses BiCMOS process technology (647 transistors) and operates from 1.0V to 5.5V supply, consuming only 3µA at 1.8V and 6µA at 3.6V. The push-pull RESET output drives low with VOL ≤ 0.3V at ISINK = 80µA (VCC ≥ 1.0V) and guarantees valid logic state down to VCC = 1V - critical for ultra-low-voltage brownout detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.31V (nominal), ±2.5% over –40°C to +125°C - ensures stable trip point across industrial temperature range without external calibration. |
| VCC Reset Timeout | 560ms (min) - holds µP in reset long enough for power rails and clocks to stabilize before code execution begins. |
| Supply Current | 3µA at +1.8V - enables multi-year operation in coin-cell–powered IoT sensors and portable medical devices. |
| MR Input Pullup | 63kΩ internal resistor - eliminates need for external pullup; supports direct connection to momentary switch to GND. |
| Operating Voltage | 1.0V to 5.5V - supports reset assertion validity during deep brownout, down to VCC = 1V, preventing premature release. |
| Output Type | Active-low push-pull - provides rail-to-rail drive strength without external pullup, simplifying PCB layout vs. open-drain variants. |
| Reset Propagation Delay | 35µs (VCC falling at 10mV/µs) - fast response to supply collapse, minimizing risk of corrupted memory writes or state transitions. |
Pinout & Package
MAX6384XS23D6 is housed in a lead-free 4-pin SC70 package (X4-1, 1.3mm × 1.1mm × 0.6mm), optimized for space-constrained portable designs. Pin 1 is RESET (active-low push-pull), Pin 2 is VCC, Pin 3 is MR (manual reset input), and Pin 4 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | RESET (active-low) | Push-pull output asserted low during reset; drives µP /RESET input directly without external components. |
| Pin 2 | VCC | Main supply input and monitored voltage source; powers internal circuitry and sets fixed reset threshold. |
| Pin 3 | MR | Active-low manual reset input with internal 63kΩ pullup; debounced internally - no external RC required. |
| Pin 4 | GND | Reference ground for all internal comparators, timers, and output drivers; must be low-impedance connection. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 2.31V with ±2.5% tolerance over full temperature range - eliminates production calibration and reduces BOM count. |
| Guaranteed reset validity | Valid RESET output state maintained down to VCC = 1V - prevents spurious release during severe brownout conditions. |
| Integrated MR debounce | No external filtering needed; 100ns glitch rejection and 1µs minimum pulse width ensure robust switch interface. |
| Negative-going transient immunity | Withstands VCC glitches up to 560µs duration when overdrive is ≤100mV - improves reliability in noisy power environments. |
| Ultra-low quiescent current | 3µA at 1.8V - extends battery life in always-on monitoring applications such as wearables and remote sensors. |

IC Role / Device Role / Timing Role: Provides primary VCC reset while enabling optional auxiliary monitoring via companion MAX6387/MAX6389 on secondary rail. Use Value: Enables single-chip reset supervision for main processor, reducing system-level complexity versus dual-supervisory IC solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326XR23D5+ | Same 2.31V threshold and 140ms timeout; SC70-3 package (no MR pin); lower supply current (1.6µA @ 1.8V). | Lacks manual reset input; suitable only where hardware reset is not required. | Select when board space is critical and MR functionality is unnecessary - saves one PCB trace and eliminates MR routing. |
| TPS3124E18DBVR | 2.32V threshold (±0.5%), 600ms timeout, 1.8V min VCC, but no MR input; SOT-23-5 package. | Higher accuracy threshold but no manual reset capability; requires external pullup for open-drain output. | Choose when tighter threshold tolerance is prioritized over MR integration and push-pull drive strength. |
Compared with MAX6384XS23D6, MAX6326XR23D5+ offers lower power and smaller footprint but omits MR, while TPS3124E18DBVR trades MR and push-pull output for higher threshold accuracy and different packaging - making each suitable for distinct subsystem constraints.

FAQ
What is the exact reset threshold voltage of MAX6384XS23D6 and how stable is it over temperature?
The MAX6384XS23D6 has a factory-set nominal reset threshold of 2.31V, with guaranteed tolerance of ±2.5% across the full operating temperature range of –40°C to +125°C. This stability is achieved through on-die trimming and temperature compensation, eliminating the need for external resistor networks or calibration in production.
Does MAX6384XS23D6 support manual reset, and what are the timing requirements for the MR input?
Yes, MAX6384XS23D6 includes a debounced manual reset (MR) input with an internal 63kΩ pullup resistor. A logic-low pulse ≥1µs on MR forces reset assertion; reset remains active for the full 560ms timeout after MR returns high. No external RC network is required due to integrated debounce.
What is the minimum supply voltage at which MAX6384XS23D6 guarantees correct RESET output behavior?
MAX6384XS23D6 guarantees valid RESET output logic state down to VCC = 1.0V. Below this level, output behavior is not specified. This feature ensures reliable brownout detection and prevents premature release of reset during deep undervoltage events.
