Product details
Overview
MAX6384XS16D3 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. It monitors single-supply voltages from +1.0V to +5.5V and consumes only 3µA at +1.8V, enabling reliable power-on reset in battery-powered embedded controllers.
For engineers reviewing the MAX6384XS16D3 datasheet, MAX6384XS16D3 pinout, MAX6384XS16D3 application, or MAX6384XS16D3 equivalent, this page delivers verified electrical parameters, SC70-4 package mapping, reset timing behavior under brownout conditions, manual reset debounce characteristics, and validated alternative parts for industrial control and portable instrumentation designs.
Technical Context
The MAX6384XS16D3 implements a precision bandgap-based voltage comparator with ±2.5% threshold accuracy across –40°C to +125°C and guarantees valid reset assertion down to VCC = 1.0V. Its internal timer enforces a fixed 140ms minimum reset timeout after VCC rises above 1.58V, independent of temperature drift.
It features a dedicated MR input with internal 63kΩ pullup resistor, supporting TTL/CMOS-compatible manual reset triggering; reset remains asserted for the full 140ms timeout after MR release. The push-pull active-low RESET output drives logic-level loads directly without external pullup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V (min), ±2.5% accuracy over –40°C to +125°C - ensures deterministic reset initiation during low-voltage brownout |
| VCC Operating Range | +1.0V to +5.5V - supports operation down to near-dead-battery conditions in portable systems |
| Reset Timeout Period | 140ms (min) - guarantees sufficient processor initialization time before release of reset signal |
| Supply Current | 3µA at +1.8V - enables multi-year battery life in always-on monitoring applications |
| MR Input Pullup | 63kΩ internal resistor - eliminates need for external pullup when MR is unused or switch-driven |
| Reset Output Type | Active-low push-pull - provides rail-to-rail drive capability without external components |
| Temperature Range | –40°C to +125°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
MAX6384XS16D3 is housed in a lead-free 4-pin SC70 package (package code X4-1), measuring 1.0mm × 1.0mm × 0.5mm, optimized for space-constrained PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Main supply input and monitored voltage source for fixed-threshold reset detection |
| 2 | RESET | Active-low push-pull output; asserts low during reset and releases high after timeout |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC via 63kΩ resistor |
| 4 | GND | Ground reference for all internal comparators, timers, and output drivers |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 1.58V with ±2.5% tolerance over full temperature range - eliminates external resistor divider calibration |
| Guaranteed reset validity | Operates correctly down to VCC = 1.0V - ensures robust reset signaling during deep brownout |
| Debounced manual reset | Internal MR filtering accepts clean logic transitions without external RC network - reduces BOM count |
| Negative-going transient immunity | Rejects VCC glitches <140µs wide at 100mV overdrive - prevents spurious resets in noisy power rails |
| Ultra-low quiescent current | 3µA at +1.8V - extends battery runtime in IoT sensor nodes and wearables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326XR16D3+ | Same 1.58V threshold and 140ms timeout, but no MR input - push-pull active-low only | Lacks manual reset capability; suitable only where software or external hardware handles reset initiation | Select when MR functionality is unnecessary and footprint compatibility with SC70-3 is required |
| TLV809K33DBZR | 3.3V reset threshold (not 1.58V); 140ms timeout; no MR input; SOT-23-3 package | Designed for higher-voltage systems; incompatible with 1.8V logic domains requiring sub-2V reset | Choose only if system operates at ≥3.0V and board layout accommodates SOT-23-3 instead of SC70-4 |
Compared with MAX6384XS16D3, MAX6326XR16D3+ offers identical timing and threshold but omits MR-reducing feature set while shrinking package size; TLV809K33DBZR shifts threshold upward by 1.72V, making it unsuitable for low-voltage brownout detection in 1.8V systems.

FAQ
What is the exact reset threshold voltage of MAX6384XS16D3 and how stable is it over temperature?
The MAX6384XS16D3 has a factory-set reset threshold of 1.58V (minimum), with nominal value 1.62V and maximum 1.67V across –40°C to +125°C. Its ±2.5% accuracy and 60ppm/°C tempco ensure predictable brownout response in automotive and industrial environments. This specification is guaranteed-not typical-and applies directly to the MAX6384XS16D3 device.
Does MAX6384XS16D3 require an external pullup resistor on the RESET pin?
No. The MAX6384XS16D3 features an active-low push-pull RESET output, meaning it actively drives both high and low states without needing an external pullup. This distinguishes it from open-drain variants like MAX6383 and eliminates one BOM item. The output remains valid down to VCC = 1.0V, and its VOL is ≤0.3V at 80µA sink current - confirmed for the MAX6384XS16D3.
How does the manual reset (MR) function behave on MAX6384XS16D3?
On the MAX6384XS16D3, the MR pin is active-low with an internal 63kΩ pullup to VCC. Driving MR low forces immediate reset assertion; reset remains active for the full 140ms timeout after MR returns high. No external debounce circuitry is needed - the MAX6384XS16D3 integrates filtering to reject noise pulses <100ns wide.
What package type and dimensions does MAX6384XS16D3 use?
The MAX6384XS16D3 uses a lead-free 4-pin SC70 package (X4-1), with footprint 1.0mm × 1.0mm and height 0.5mm. Pin 1 is VCC, pin 2 is RESET, pin 3 is MR, and pin 4 is GND - matching the top-view diagram in the official Maxim datasheet for MAX6384XS16D3.
Can MAX6384XS16D3 operate reliably during brief VCC supply glitches?
Yes. The MAX6384XS16D3 provides negative-going VCC transient immunity: it ignores glitches shorter than ~140µs when the overdrive (VTH – VCC) is 100mV, per the "Maximum Transient Duration vs. Reset Comparator Overdrive" curve. This behavior is measured and specified for the MAX6384XS16D3, preventing false resets in electrically noisy environments.
