Product details
Overview
The MAX6382XR24D6 from Maxim Integrated is a single-channel, active-high push-pull microprocessor supervisory circuit designed to monitor +2.4V supply rails in low-power embedded systems. It features a factory-set reset threshold of +2.40V (±2.5% over –40°C to +125°C), 560ms minimum reset timeout, 3µA supply current at +1.8V, and guaranteed valid reset output down to VCC = 1V. It is used in battery-powered controllers and portable instrumentation requiring reliable power-on reset.
For engineers reviewing the MAX6382XR24D6 datasheet, MAX6382XR24D6 pinout, MAX6382XR24D6 application, or MAX6382XR24D6 equivalent, key selection considerations include its SC70-3 package, active-high push-pull RESET output, precise +2.4V threshold, 560ms timeout, and compatibility with 1.8V–5.5V VCC operation in space-constrained industrial and portable designs.
Technical Context
This device implements a precision bandgap-based voltage comparator with internal hysteresis and a digital timeout counter. The reset assertion is triggered when VCC falls below +2.40V, and the active-high RESET output remains asserted for ≥560ms after VCC rises above the threshold.
No manual reset (MR) or auxiliary RESET IN inputs are present on the MAX6382XR24D6 variant - it is a minimal-feature member of the MAX6381–MAX6390 family optimized for fixed-threshold, single-supply monitoring with ultra-low quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | +2.40V (nominal), ±2.5% over –40°C to +125°C - ensures accurate brownout detection across automotive and industrial temperature ranges |
| Reset Timeout | 560ms (minimum) - provides sufficient hold time for µP initialization before release |
| Supply Current | 3µA at +1.8V - enables multi-year battery life in always-on sensor nodes |
| VCC Range | +1.0V to +5.5V - supports operation during deep brownout and compatibility with 1.8V/2.5V/3.3V/5V logic domains |
| Output Type | Active-high push-pull - eliminates need for external pull-up resistor and drives high directly |
| Reset Validity | Guaranteed down to VCC = 1V - maintains defined logic state even during severe undervoltage conditions |
| Tempco | 60ppm/°C - limits threshold drift to <±15mV over full temperature range |
Pinout & Package
MAX6382XR24D6 is housed in a 3-pin SC70-3 package (package code X3-2), measuring 2.0mm × 2.1mm × 0.95mm, with gull-wing leads and lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and output driver; must be connected to system ground plane |
| 2 | RESET | Active-high push-pull output; asserts high during reset condition and deasserts low upon timeout completion |
| 3 | VCC | Power supply input and monitored voltage rail; powers internal circuitry and serves as primary reset trigger source |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed threshold | +2.40V with ±2.5% accuracy over –40°C to +125°C - eliminates external resistor network and calibration |
| Ultra-low ICC | 3µA at +1.8V - reduces standby power in energy-harvesting and coin-cell applications |
| Push-pull active-high output | Drives high directly without pull-up; compatible with CMOS/TTL inputs and eliminates BOM cost |
| Valid reset at low VCC | RESET logic state guaranteed down to VCC = 1V - prevents undefined behavior during deep brownout |
| Negative transient immunity | Rejects VCC glitches ≤560µs (at 100mV overdrive) - improves robustness in noisy power environments |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |
|---|---|
Use Scenario: Wearable ECG sensor operating from a 2.4V lithium-thionyl chloride cell with strict 10-year shelf-life requirement. IC Role / Device Role / Timing Role: Monitors VCC during cold-start and brownout; asserts active-high RESET to hold MCU in reset until stable 2.4V rail is confirmed. Use Value: 3µA quiescent current extends battery life; 560ms timeout ensures reliable bootloader execution before firmware launch. | Use Scenario: DIN-rail mounted analog input module powered by isolated 2.4V DC-DC converter in factory automation cabinet. IC Role / Device Role / Timing Role: Detects undervoltage on 2.4V logic rail caused by transformer saturation or cable fault; triggers system-wide reset via active-high signal. Use Value: ±2.5% threshold accuracy prevents nuisance resets during line fluctuations; SC70-3 footprint saves PCB area in dense I/O layouts. |
| Smart Utility Meters | Automotive Body Control Units |
Use Scenario: AMI meter with dual-supply architecture where 2.4V rail powers real-time clock and secure element. IC Role / Device Role / Timing Role: Supervises 2.4V RTC supply independently; generates clean, glitch-free active-high reset pulse synchronized to power stabilization. Use Value: 60ppm/°C tempco ensures threshold stability across –40°C to +85°C meter operating range; no MR pin simplifies layout. | Use Scenario: Low-voltage sub-module (e.g., mirror control) powered from vehicle's 2.4V auxiliary domain during start-stop cycles. IC Role / Device Role / Timing Role: Detects VCC sag below +2.4V during cranking; holds microcontroller in reset until rail recovers and remains stable for ≥560ms. Use Value: Guaranteed operation down to VCC = 1V prevents spurious reset release during transient dips; AEC-Q100 qualification supported per family data. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326XR24D5 | Same +2.4V threshold and SC70-3 package, but 20ms reset timeout (vs. 560ms) | Suitable for fast-boot systems where short reset hold time is required | Select when faster release is needed; not drop-in due to timeout mismatch |
| TPS3124E18DBVR | +2.4V threshold, 500ms timeout, SOT-23-3 package, 1.5µA ICC at +1.8V | Lower supply current but different pinout (GND/VCC/RESET vs. GND/RESET/VCC); requires PCB redesign | Choose for ultra-low-power priority if layout revision is acceptable |
Compared with MAX6382XR24D6, MAX6326XR24D5 offers significantly shorter reset hold time (20ms vs. 560ms), while TPS3124E18DBVR delivers lower ICC but incompatible pin mapping - both require design validation for timing margins and board layout changes.

FAQ
What is the exact reset threshold voltage of the MAX6382XR24D6?
The MAX6382XR24D6 has a factory-set nominal reset threshold of +2.40V, with guaranteed tolerance of ±2.5% over the full operating temperature range (–40°C to +125°C). This value is laser-trimmed during production and does not require external components. The MAX6382XR24D6 datasheet specifies min/max bounds of +2.34V and +2.46V at +25°C, tightening to +2.31V and +2.49V across temperature.
Does the MAX6382XR24D6 include a manual reset input (MR)?
No, the MAX6382XR24D6 does not feature a manual reset input. It belongs to the MAX6381/MAX6382/MAX6383 subgroup, which omits MR and RESET IN pins to minimize size and cost. Only MAX6384–MAX6390 variants include MR; the MAX6382XR24D6 relies solely on VCC monitoring and provides no provision for external reset initiation.
What is the function of the RESET pin on the MAX6382XR24D6?
The RESET pin on the MAX6382XR24D6 is an active-high push-pull output. It drives high (to VCC level) when VCC falls below +2.40V or during power-up, and remains high for ≥560ms after VCC rises above the threshold. It drives low when deasserted, requiring no external pull-up resistor - unlike open-drain variants in the same family.
Can the MAX6382XR24D6 operate reliably at VCC = 1.2V?
Yes, the MAX6382XR24D6 guarantees correct RESET output logic state down to VCC = 1.0V, per its Absolute Maximum Ratings and Electrical Characteristics table. At VCC = 1.2V, the device continues to monitor the supply and assert RESET appropriately, with VOL ≤ 0.3V and VOH ≥ 0.8×VCC under specified load conditions - enabling use in deep brownout recovery scenarios.
Which package does the MAX6382XR24D6 use, and what are its dimensions?
The MAX6382XR24D6 uses the 3-pin SC70-3 package (package code X3-2), with overall dimensions of 2.0mm × 2.1mm × 0.95mm and gull-wing surface-mount leads. Its pinout is GND (pin 1), RESET (pin 2), VCC (pin 3), matching JEDEC MO-203AA standard - distinct from the 4-pin SC70 and 6-pin µDFN variants in the same family.
