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 (XS16), 140ms minimum VCC reset timeout (D3), and debounced manual reset input (MR). It monitors single supply voltage (1.0V–5.5V), consumes only 3μA at 1.8V, and guarantees valid reset state down to VCC = 1V. Used in portable battery-powered equipment requiring reliable power-on reset and field-serviceable manual reset.
For engineers reviewing the MAX6384XS16D3+T datasheet, MAX6384XS16D3+T pinout, MAX6384XS16D3+T application, or MAX6384XS16D3+T equivalent, key selection criteria include reset threshold accuracy (±2.5% over –40°C to +125°C), MR internal pullup value (63kΩ), SC70-4 package footprint, and compatibility with dual-voltage system monitoring via external resistor divider on MR.
Technical Context
The MAX6384XS16D3+T implements a precision bandgap-based reset comparator with ±2.5% threshold accuracy across –40°C to +125°C and 60ppm/°C tempco. Its internal timer generates a guaranteed-minimum 140ms reset assertion after VCC rises above 1.58V or after MR release.
It features a debounced manual reset input with 1μs minimum pulse width support, 100ns glitch rejection, and 200ns MR-to-reset delay. The active-low push-pull RESET output drives low to 0.3V at 1.2mA sink (VCC ≥ 2.5V) and guarantees logic-high state (VOH ≥ 0.8×VCC) when deasserted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V (factory-trimmed XS16 suffix); ±2.5% tolerance over full temperature range ensures robust brownout detection in low-voltage systems. |
| VCC Reset Timeout | 140ms min (D3 suffix); holds μP in reset long enough for stable power rail settling and oscillator startup. |
| Supply Current | 3μA at +1.8V; enables multi-year operation in coin-cell–powered IoT sensors and wearables. |
| Operating Voltage Range | 1.0V to 5.5V; supports direct interface with 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifting. |
| Reset Output Type | Active-low push-pull; eliminates need for external pullup resistor and provides fast, low-impedance reset assertion/deassertion. |
| Manual Reset Input | MR with 63kΩ internal pullup; allows momentary switch connection to GND for field reset without external components. |
| Temperature Range | –40°C to +125°C; qualified for industrial and automotive under-hood applications. |
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, suitable for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary power supply input; monitored for reset generation and powers internal circuitry (1.0V–5.5V range). |
| 2 | RESET | Active-low push-pull reset output; drives low during fault conditions and remains asserted for 140ms after recovery. |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC (63kΩ); asserts reset when pulled ≤0.3×VCC. |
| 4 | GND | Analog and digital ground reference; must be connected to system ground plane for accurate threshold sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-set reset threshold | 1.58V (XS16) with ±2.5% accuracy over –40°C to +125°C-enables precise low-voltage brownout detection without external resistors. |
| Debounced manual reset input | MR pin includes 100ns glitch rejection and 1μs minimum pulse width support-eliminates need for external RC debounce networks. |
| Low supply current | 3μA at 1.8V-extends battery life in always-on portable instrumentation and sensor nodes. |
| Valid reset output down to VCC = 1V | Guaranteed logic-level integrity of RESET signal even during deep brownout-ensures deterministic μP initialization before power collapse. |
| Push-pull active-low output | No external pullup required; sinks 1.2mA at 0.3V (VCC ≥ 2.5V)-reduces BOM count and improves noise immunity vs. open-drain alternatives. |
Applications
| Portable/Battery-Powered Equipment | Critical μP and μC Power Monitoring |
|---|---|
Use Scenario: Coin-cell–powered environmental sensor node operating at 1.8V with intermittent BLE transmission.

Use Value: Enables zero-crossing–free calibration sequence initiation without software intervention, reducing firmware complexity and test time. |
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 manual reset input (MR); 3-pin SC70 package. | Lacks field-serviceable reset capability; suited for fixed-function embedded systems where manual intervention is unnecessary. | Select when board space is constrained and MR functionality is not required-saves one PCB trace and reduces routing complexity. |
| TPS3808G16DBVR | 1.6V threshold (±0.5% typical), 200ms timeout, 1.8V–6.5V VCC range; 5-pin SOT-23 package with enable input. | Includes EN pin for system-level reset control; higher accuracy but larger footprint and no integrated MR pullup. | Choose when tighter threshold tolerance and system-controlled reset gating are prioritized over compact size and hardware-button simplicity. |
Compared with MAX6326XR26D3+T, MAX6384XS16D3+T adds MR functionality in a 4-pin SC70 at minimal area cost; versus TPS3808G16DBVR, it trades threshold accuracy and enable flexibility for smaller size, lower quiescent current (3μA vs. 8μA), and integrated MR pullup-making it optimal for space- and power-sensitive portable designs.

FAQ
What is the exact reset threshold voltage and tolerance for MAX6384XS16D3+T?
The MAX6384XS16D3+T has a factory-set reset threshold of 1.58V (XS16 suffix), with guaranteed ±2.5% accuracy over the full operating temperature range of –40°C to +125°C. This means the actual threshold falls between 1.54V and 1.62V at +25°C, and between 1.52V and 1.64V across the entire temperature range-ensuring consistent brownout detection in low-voltage systems.
Does MAX6384XS16D3+T support manual reset, and what is the MR input behavior?
Yes, MAX6384XS16D3+T includes a debounced manual reset input (MR) with an internal 63kΩ pullup resistor to VCC. Driving MR low asserts the active-low RESET output immediately and holds it asserted for the full 140ms timeout period after MR is released. MR accepts TTL/CMOS logic levels and requires no external components-ideal for pushbutton integration in portable and field-serviceable equipment.
What package type and dimensions does MAX6384XS16D3+T use?
MAX6384XS16D3+T is packaged in a lead(Pb)-free, RoHS-compliant 4-pin SC70 (SOT-323) package, outline number 21-0098, with land pattern 90-0187. Its footprint measures 2.0mm × 2.1mm, height 0.95mm, and thermal resistance θJA = 322.6°C/W on a multilayer board-optimized for high-density PCB layouts in space-constrained portable electronics.
Can MAX6384XS16D3+T operate reliably at VCC = 1.0V?
Yes, MAX6384XS16D3+T guarantees correct RESET output logic state down to VCC = 1.0V. Its internal circuitry remains functional and the push-pull output maintains valid low/high levels even during deep brownout conditions-ensuring deterministic microprocessor initialization before complete power collapse, a critical requirement in battery-depleted scenarios.
Is MAX6384XS16D3+T pin-compatible with legacy Maxim reset ICs like MAX809?
Yes, MAX6384XS16D3+T is pin-compatible with MAX809/MAX810/MAX803 and other members of the MAX6326–MAX6348 series in the same 4-pin SC70 package. This allows drop-in replacement in existing designs-retaining identical PCB layout, footprint, and interconnect while upgrading to lower quiescent current (3μA vs. ~15μA), tighter threshold accuracy, and integrated MR functionality.
