Product details
Overview
The MAX6384XS23D3+T 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), 140ms minimum VCC reset timeout, and debounced manual reset input. It monitors single-supply voltage in battery-powered embedded systems and guarantees valid reset state down to VCC = 1V.
For engineers reviewing the MAX6384XS23D3+T datasheet, MAX6384XS23D3+T pinout, MAX6384XS23D3+T application, or MAX6384XS23D3+T equivalent, key selection factors include its 4-pin SC70 package, 3μA supply current at 1.8V, ±2.5% threshold accuracy, and MR input with internal 63kΩ pullup - critical for portable equipment and industrial controllers requiring reliable power-on reset and field-serviceable manual reset capability.
Technical Context
This device implements a precision bandgap-based voltage comparator with hysteresis and an internal monostable timer. The reset assertion is triggered when VCC falls below 2.31V or when the MR pin is pulled low, with independent timeout periods for VCC recovery (140ms min) and MR release (140ms min).
It features guaranteed logic-level validity of the RESET output down to VCC = 1V, negative-going VCC transient immunity up to 100mV overdrive for ≤35µs, and operates across -40°C to +125°C with ±2.5% reset threshold stability over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.31V (nominal), ±2.5% over -40°C to +125°C - ensures stable brownout detection across automotive/industrial temperature range |
| VCC Reset Timeout | 140ms (minimum) - guarantees sufficient processor initialization time after power stabilization |
| Supply Current | 3μA at +1.8V - enables multi-year operation in coin-cell–powered IoT sensors |
| MR Pullup Resistance | 63kΩ (typical) - allows direct connection of momentary switch without external components |
| Operating Voltage Range | 1.0V to 5.5V - supports operation during deep brownout and compatibility with 1.2V–5V logic domains |
| Reset Output Type | Active-low push-pull - eliminates need for external pullup resistor and drives standard CMOS/TTL inputs directly |
| MR Input Pulse Width | 1μs minimum - rejects noise spikes while responding reliably to user-initiated resets |
Pinout & Package
MAX6384XS23D3+T is housed in a RoHS-compliant 4-pin SC70 package (outline 21-0098, land pattern 90-0187), measuring 2.0mm × 2.1mm × 0.95mm, optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary power supply input and monitored voltage source; accepts 1.0V–5.5V; powers internal circuitry and reference |
| 2 | RESET | Active-low push-pull reset output; sinks ≥1.2mA at VCC ≥2.5V; asserts low during VCC undervoltage or MR activation |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC via 63kΩ; requires <0.3×VCC to assert reset |
| 4 | GND | Analog and digital ground reference; must be connected to system ground plane for accurate threshold sensing |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 2.31V with ±2.5% tolerance over full temperature range - eliminates external resistor divider and calibration effort |
| Debounced manual reset input | Integrated 63kΩ internal pullup and 100ns glitch rejection - enables direct switch connection without RC filtering |
| Low-voltage operation guarantee | Valid RESET output state maintained down to VCC = 1V - ensures deterministic behavior during deep brownout |
| Negative-going VCC transient immunity | Rejects transients ≤35µs wide with 100mV overdrive - prevents spurious resets in noisy power environments |
| Ultra-low quiescent current | 3μA at 1.8V - extends battery life in always-on monitoring applications by >10× versus legacy supervisors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326XR23D3+T | Same 2.31V threshold and 140ms timeout, but no MR input; 3-pin SC70 package | Lacks manual reset capability; suitable only for fixed-reset applications without field service requirement | Select when board space is constrained and manual reset is unnecessary |
| TPS3124E18DBVR | 2.63V threshold (not 2.31V); 200ms timeout; 1.8V–5.5V operation; SOT-23-5 package | Different threshold and longer timeout; requires external pullup on MR; higher 8μA ICC at 1.8V | Select when 2.63V threshold aligns with system rail and SOT-23 footprint is preferred |
Compared with MAX6326XR23D3+T and TPS3124E18DBVR, the MAX6384XS23D3+T uniquely combines 2.31V threshold, 140ms timeout, integrated MR pullup, and 4-pin SC70 packaging - making it optimal for compact, manually serviceable, low-voltage embedded systems where precise brownout detection and field reset are mandatory.

FAQ
What is the exact reset threshold voltage of the MAX6384XS23D3+T?
The MAX6384XS23D3+T has a factory-set nominal reset threshold of 2.31V, with guaranteed tolerance of ±2.5% over the full operating temperature range (-40°C to +125°C). This value is confirmed in the Reset Thresholds table of the datasheet, where suffix "23" corresponds to VTH(nom) = 2.31V, VTH(min) = 2.26V, and VTH(max) = 2.37V at +25°C.
Does the MAX6384XS23D3+T support manual reset functionality?
Yes, the MAX6384XS23D3+T includes a debounced manual reset input (MR pin) with an internal 63kΩ pullup resistor to VCC. Driving MR low forces an immediate reset assertion, which remains active for 140ms after MR is released. This feature is explicitly documented in the General Description and Pin Description sections for MAX6384/MAX6385/MAX6386/MAX6390 variants.
What package type and dimensions does the MAX6384XS23D3+T use?
The MAX6384XS23D3+T uses a 4-pin SC70 package (outline number 21-0098, land pattern 90-0187), measuring 2.0mm × 2.1mm × 0.95mm. This RoHS-compliant, lead-free package is confirmed in the Ordering Information table under "MAX6384XS__D_+T" with "4 SC70" designation and thermal resistance data (θJA = 322.6°C/W).
What is the minimum supply voltage at which the MAX6384XS23D3+T guarantees valid reset output logic levels?
The MAX6384XS23D3+T guarantees correct RESET output logic state down to VCC = 1.0V, as stated in the Absolute Maximum Ratings and Detailed Description sections. This ensures deterministic reset behavior during deep brownout conditions where other supervisors may fail to drive valid logic levels.
How does the reset timeout behavior differ between VCC recovery and manual reset release on the MAX6384XS23D3+T?
For the MAX6384XS23D3+T, both VCC recovery and MR release trigger the same 140ms minimum reset timeout period (suffix D3), as confirmed in the Reset Timeout Delay table and General Description. Unlike MAX6390, this part does not implement separate VCC and MR timeout durations - both events hold RESET low for ≥140ms after the initiating condition ends.
