Product details
Overview
MAX6384XS16D3-T from Maxim Integrated is a low-power microprocessor supervisory circuit with active-low push-pull reset output, factory-set 1.58V reset threshold (±2.5% over -40°C to +125°C), 140ms minimum VCC reset timeout, and debounced manual reset input (MR). It monitors single supply voltage in battery-powered or space-constrained embedded systems where reliable power-on reset and brownout protection are critical.
For engineers reviewing the MAX6384XS16D3-T datasheet, MAX6384XS16D3-T pinout, MAX6384XS16D3-T application, or MAX6384XS16D3-T equivalent, key selection criteria include its 4-pin SC70 package, guaranteed reset validity down to VCC = 1V, ±2.5% threshold accuracy across automotive temperature range, and integrated MR pullup resistor (63kΩ).
Technical Context
The MAX6384XS16D3-T implements a precision bandgap-based reset comparator with 60ppm/°C tempco and guarantees reset assertion during VCC drop below 1.58V, holding reset for ≥140ms after VCC recovers above threshold. Its internal MR pullup resistor (63kΩ) enables direct connection of a momentary switch to GND without external components.
It features negative-going VCC transient immunity up to 100µs at 100mV overdrive and ensures valid reset logic state even as VCC declines to 1.0V - critical for orderly shutdown in low-voltage portable systems. The device operates from 1.0V to 5.5V and draws only 3µA at 1.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V (factory-trimmed), ±2.5% accuracy over -40°C to +125°C - ensures consistent reset point across automotive temperature range |
| Reset Timeout | 140ms minimum - provides sufficient hold time for microprocessor initialization after power recovery |
| Supply Current | 3µA at VCC = 1.8V - enables multi-year operation in coin-cell–powered IoT sensors |
| Operating Voltage | 1.0V to 5.5V - supports direct interface with 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic domains |
| MR Input Pullup | 63kΩ internal resistor - eliminates need for external pullup; allows direct switch-to-GND manual reset |
| Reset Output Type | Active-low push-pull - drives RESET low without external pullup; sinks 3.2mA at VCC ≥ 4.5V |
| VCC Reset Validity | Guaranteed down to VCC = 1.0V - maintains correct reset polarity during deep brownout |
Pinout & Package
MAX6384XS16D3-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 high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary supply input and monitored voltage rail; powers internal circuitry and reset comparator |
| 2 | RESET | Active-low push-pull output; asserts low during reset condition and remains low for ≥140ms after VCC recovery |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC via 63kΩ resistor; initiates reset when driven low |
| 4 | GND | Ground reference for all internal circuits and reset comparator; must be connected to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 1.58V with ±2.5% tolerance over full -40°C to +125°C range - eliminates external calibration and reduces BOM count |
| Debounced manual reset input | Integrated 63kΩ MR pullup and 1µs glitch rejection - enables direct switch interface without RC network or firmware debounce |
| Negative-going VCC transient immunity | Withstands ≤100µs transients at 100mV overdrive - prevents false resets in electrically noisy environments |
| Low-voltage operation | Functional down to VCC = 1.0V with guaranteed reset state - supports graceful shutdown in ultra-low-power systems |
| Small-footprint packaging | 4-pin SC70 (2.0mm × 2.1mm) - saves >60% board area vs. traditional SOT-23 while maintaining hand-solderability |

IC Role / Device Role / Timing Role: Supervises 3.3V supply and triggers system-wide reset via MR-linked GPIO; operates across -25°C to +70°C ambient. Use Value: 4-pin SC70 footprint minimizes layout area in compact enclosure; ±2.5% threshold stability avoids spurious resets in temperature-cycling environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326XR26D3+T | Same 1.58V threshold and 140ms timeout, but no MR input; 3-pin SC70 package | Lacks manual reset capability; suitable only for systems with software-only reset control | Select when MR functionality is unnecessary and board area is constrained to 3-pin footprint |
| TPS3123E15DBVR | 1.55V threshold (±0.5%), 200ms timeout, 1.8–5.5V operation, 1.6µA ICC at 3.3V | Higher accuracy and lower current, but requires external pullup for open-drain RESET; no MR input | Prefer for ultra-low-power designs needing tighter threshold tolerance, accepting added external component |
Compared with MAX6384XS16D3-T, MAX6326XR26D3+T saves one pin but removes manual reset flexibility, while TPS3123E15DBVR offers superior accuracy and lower current at the cost of open-drain output and no MR - making MAX6384XS16D3-T optimal for space-limited designs requiring both precise threshold and hardware-initiated reset.

FAQ
What is the exact reset threshold voltage of MAX6384XS16D3-T and how stable is it over temperature?
The MAX6384XS16D3-T has a factory-set reset threshold of 1.58V, specified with ±2.5% accuracy over the full operating temperature range of -40°C to +125°C. Its reset threshold tempco is 60ppm/°C, ensuring minimal drift across thermal extremes. This stability is verified per Maxim's production test flow and documented in the Electrical Characteristics table of the official datasheet.
Does MAX6384XS16D3-T support manual reset, and what is the internal MR pullup value?
Yes, MAX6384XS16D3-T includes a debounced manual reset input (MR) with an internal 63kΩ pullup resistor to VCC. This allows direct connection of a normally open momentary switch between MR and GND - no external components required. The MR input accepts TTL/CMOS logic levels and features 1µs minimum pulse width and 100ns glitch rejection.
What package type and dimensions does MAX6384XS16D3-T use?
MAX6384XS16D3-T is supplied in a 4-pin SC70 package (outline number 21-0098), measuring 2.0mm × 2.1mm × 0.95mm. It is RoHS-compliant (+ suffix), with land pattern 90-0187. This package provides superior thermal performance (θJA = 322.6°C/W) versus larger alternatives while enabling high-density routing in portable designs.
Can MAX6384XS16D3-T operate reliably at VCC = 1.2V, and what happens to the RESET output?
Yes, MAX6384XS16D3-T is guaranteed to maintain valid RESET output logic state down to VCC = 1.0V. At 1.2V, the active-low push-pull RESET output continues to sink ≥80µA with VOL ≤ 0.3V when asserted, and sources sufficient current to drive standard CMOS inputs when deasserted - ensuring robust interface with sub-1.8V microcontrollers.
Is MAX6384XS16D3-T pin-compatible with any legacy Maxim reset ICs?
MAX6384XS16D3-T is pin-compatible with other members of the MAX6384–MAX6386 series in the same 4-pin SC70 package, including MAX6384XS26D3-T and MAX6385XS16D3-T. It is not pin-compatible with 3-pin SC70 devices (e.g., MAX6326) or 6-pin µDFN variants due to differing pin count and MR placement.
