Product details
Overview
MAX6384XS17D3+ from Maxim Integrated is a low-power microprocessor supervisory circuit with factory-set 1.67V reset threshold, 140ms minimum VCC reset timeout, active-low push-pull reset output, and debounced manual reset input (MR). It monitors +1.8V to +5.0V supply rails in battery-powered embedded systems, ensuring reliable power-on reset and brownout protection for critical µP initialization.
For engineers reviewing the MAX6384XS17D3+ datasheet, MAX6384XS17D3+ pinout, MAX6384XS17D3+ application, or MAX6384XS17D3+ equivalent, key selection criteria include guaranteed reset assertion down to VCC = 1V, ±2.5% threshold accuracy over –40°C to +125°C, 3µA supply current at +1.8V, SC70-4 package compatibility, and MR input with internal 63kΩ pullup resistor.
Technical Context
The MAX6384XS17D3+ integrates a precision voltage comparator with a factory-trimmed 1.67V threshold (±2.5% over temperature), a monostable timer for 140ms minimum reset assertion after VCC recovery, and a dedicated MR input with internal pullup and 1µs minimum pulse width support. Its push-pull active-low RESET output guarantees valid logic state down to VCC = 1V.
It operates across 1.0V to 5.5V supply range, consumes only 3µA at +1.8V, and provides immunity to negative-going VCC transients via built-in glitch rejection (100ns MR debounce, 35µs VCC-to-reset delay). No external components are required for basic operation beyond VCC decoupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.67V ±2.5% (–40°C to +125°C); ensures reliable detection of 1.8V rail brownout before µP malfunctions |
| Reset Timeout Period | 140ms minimum (VCC recovery); holds µP in reset long enough for stable clock and supply settling |
| Supply Current | 3µA at +1.8V; enables multi-year battery life in portable instrumentation and IoT edge nodes |
| Operating Voltage Range | 1.0V to 5.5V; supports operation during deep brownout and compatibility with 1.2V–5V logic domains |
| MR Input Pullup | 63kΩ internal resistor; eliminates need for external pullup when using momentary switch to GND |
| RESET Output Type | Active-low push-pull; drives low without external pullup, sinks 3.2mA at VCC ≥ 4.5V for direct µP reset pin interface |
| Temperature Range | –40°C to +125°C; qualified for automotive under-hood, industrial control, and harsh-environment applications |
Pinout & Package
MAX6384XS17D3+ is housed in a lead-free 4-pin SC70 package (X4-1, 1.0mm × 1.3mm × 0.6mm), optimized for space-constrained PCB layouts in portable and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power supply input | Primary monitored voltage rail; powers internal circuitry and sets fixed reset threshold |
| 2 - RESET | Active-low push-pull reset output | Drives µP reset pin low during fault; remains asserted for full 140ms after VCC recovery |
| 3 - MR | Active-low manual reset input | Debounced input with internal 63kΩ pullup; asserts reset when pulled low, even during VCC brownout |
| 4 - GND | Ground reference | Return path for all internal currents; must be connected directly to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Factory-set 1.67V reset threshold | Eliminates external resistor divider; reduces BOM count and layout area in 1.8V systems |
| 140ms minimum reset timeout | Guarantees µP reset hold time exceeds typical oscillator startup and PLL lock durations |
| MR input with internal 63kΩ pullup | Enables single-switch manual reset without external components; supports TTL/CMOS drive |
| Valid RESET output down to VCC = 1V | Ensures deterministic reset behavior during deep undervoltage events, preventing runaway code execution |
| 3µA supply current at +1.8V | Extends battery runtime in always-on monitoring devices such as medical sensors and asset trackers |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar µP reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326XR17D3+ | Same 1.67V threshold and 140ms timeout, but no MR input; SC70-3 package (3-pin) | Lacks manual reset capability; suitable only for systems requiring VCC-only supervision | Select when board space is constrained and MR functionality is unnecessary |
| TPS3123E17DBVR | 1.67V threshold, 200ms timeout, 1.8V–5.5V range, but 10µA ICC at +1.8V and no internal MR pullup | Requires external MR pullup resistor; higher quiescent current reduces battery life in ultra-low-power designs | Choose only if TI supply chain alignment or qualification requirements override current consumption needs |
Compared with MAX6384XS17D3+, MAX6326XR17D3+ saves one pin and footprint but removes MR flexibility, while TPS3123E17DBVR trades higher supply current and external component dependency for alternate vendor sourcing-neither offers identical feature parity.

FAQ
What is the exact reset threshold voltage of the MAX6384XS17D3+?
The MAX6384XS17D3+ has a factory-set reset threshold of 1.67V, with ±2.5% accuracy over the full operating temperature range of –40°C to +125°C. This value is laser-trimmed during production and does not require external calibration. The '17' suffix in the part number explicitly denotes the 1.67V threshold per Maxim's ordering guide.
Does the MAX6384XS17D3+ require an external pullup resistor on the MR pin?
No, the MAX6384XS17D3+ includes an internal 63kΩ pullup resistor on the MR pin, allowing direct connection of a momentary switch to GND without external components. This simplifies design and reduces BOM count. The internal pullup ensures MR remains high when unconnected, preventing spurious resets.
What is the minimum reset timeout period for the MAX6384XS17D3+?
The MAX6384XS17D3+ provides a minimum reset timeout period of 140ms after VCC rises above the 1.67V threshold. This is specified as 'D3' in the part number and is guaranteed over temperature and process variation. The actual timeout may extend up to 280ms under worst-case conditions per the datasheet's electrical characteristics table.
Can the MAX6384XS17D3+ operate reliably at VCC = 1.0V?
Yes, the MAX6384XS17D3+ 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 throughout this range, enabling robust reset assertion during deep brownout conditions where other supervisors may fail.
Which package type does the MAX6384XS17D3+ use, and what are its dimensions?
The MAX6384XS17D3+ uses the 4-pin SC70 package (pkg code X4-1), measuring 1.0mm × 1.3mm × 0.6mm with standard SC70 lead pitch. This compact, surface-mount package supports high-density layouts in space-constrained applications such as wearables and modular sensor nodes.
