Product details
Overview
MAX6382XR24D6-T from Maxim Integrated is a push-pull active-high microprocessor supervisory circuit with factory-set 2.40V reset threshold, 560ms minimum VCC reset timeout, and guaranteed operation down to VCC = 1.0V. It monitors single supply voltage in low-power embedded systems, asserts RESET high during brownout or power-up, and maintains valid logic state across -40°C to +125°C for critical μP initialization in portable equipment and industrial controllers.
For engineers reviewing the MAX6382XR24D6-T datasheet, MAX6382XR24D6-T pinout, MAX6382XR24D6-T application, or MAX6382XR24D6-T equivalent, key selection criteria include its active-high push-pull output, ±2.5% threshold accuracy over temperature, 3μA supply current at 1.8V, and SC70-3 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX6382XR24D6-T implements a precision bandgap-based voltage comparator with internal 2.40V reference and a monolithic RC timer for fixed 560ms reset assertion after VCC recovery. Its active-high push-pull output drives directly into μP reset inputs without external pullup, eliminating board-level components required by open-drain alternatives.
No manual reset (MR) or auxiliary RESET IN inputs are integrated-this variant is optimized for single-supply monitoring only. Reset assertion is guaranteed valid for VCC ≥ 1.0V, enabling reliable boot sequencing even during deep brownout conditions before full rail stabilization.
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/industrial temperature range |
| VCC Reset Timeout | 560ms minimum - provides sufficient hold time for μP core and peripherals to stabilize post-power-up |
| Supply Current | 3μA at VCC = 1.8V - enables multi-year battery life in always-on sensor nodes and portable devices |
| Operating Voltage Range | 1.0V to 5.5V - supports valid reset assertion during deep undervoltage events down to near-dead-battery conditions |
| Output Type | Active-high push-pull - eliminates need for external pullup resistor, reduces BOM count and layout area |
| Reset Output Validity | Guaranteed down to VCC = 1.0V - ensures deterministic μP state initialization even under severe supply sag |
| Package | 3-pin SC70 - 1.25mm × 0.85mm footprint ideal for wearables, IoT edge nodes, and compact industrial modules |
Pinout & Package
MAX6382XR24D6-T is housed in a RoHS-compliant 3-pin SC70 package (outline 21-0075), with 0.65mm pitch and thermal resistance θJA = 340.4°C/W on multilayer board.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull output - drives μP reset input directly; sinks/source current per spec without external components |
| 2 | VCC | Main supply input and monitored voltage rail - powers internal circuitry and serves as primary reset trigger source |
| 3 | GND | Analog/digital ground reference - must be connected to system ground plane for stable threshold and timing performance |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 2.40V threshold | Eliminates external resistor divider calibration, reducing design cycle time and production test complexity |
| 560ms fixed reset timeout | Matches typical μP power-on reset requirements without requiring external timing capacitors or configuration pins |
| 3μA supply current at 1.8V | Enables integration into energy-harvesting and coin-cell-powered applications where quiescent current dominates lifetime |
| ±2.5% threshold accuracy over temperature | Ensures consistent reset behavior across automotive (-40°C to +125°C) and industrial operating environments |
| Active-high push-pull output | Directly interfaces with standard μP reset inputs, avoiding level-shifting or pullup conflicts in mixed-voltage systems |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |
|---|---|
Use Scenario: Battery-powered glucose monitor with BLE radio that must initialize reliably after cold start or battery replacement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD3-T | 2.93V reset threshold, 240ms timeout, same SC70-3 package | Higher threshold suits 3.3V systems; shorter timeout may not meet slow-rail μP requirements | Select when monitoring 3.3V rails with faster power-up profiles and no need for sub-3V brownout detection |
| TPS3808G33DBVR | 3.3V threshold, 200ms timeout, SOT-23-5 package with MR input | Includes manual reset capability and different pinout; requires PCB redesign | Choose if system requires operator-initiated reset or dual-voltage supervision beyond single-rail monitoring |
Compared with MAX809TRD3-T and TPS3808G33DBVR, the MAX6382XR24D6-T offers lower threshold (2.40V vs. 2.93V/3.3V) and longer timeout (560ms vs. 240ms/200ms), making it uniquely suited for 2.4–2.5V logic domains and applications demanding extended reset hold times for complex power sequencing.

FAQ
What is the exact reset threshold voltage of MAX6382XR24D6-T and how is it specified over temperature?
The MAX6382XR24D6-T has a nominal reset threshold of 2.40V, with tolerance of ±2.5% over the full operating temperature range of -40°C to +125°C. This means the actual threshold falls between 2.34V and 2.46V at any point within that range, ensuring consistent brownout detection without calibration. The specification is guaranteed by design and applies to all units shipped under this part number.
Does MAX6382XR24D6-T support manual reset functionality or auxiliary voltage monitoring?
No, the MAX6382XR24D6-T does not include manual reset (MR) input or auxiliary RESET IN functionality. It is a dedicated single-supply supervisory device with only VCC monitoring and active-high push-pull RESET output. For designs requiring MR or dual-rail supervision, consider MAX6384XR24D6-T or MAX6387XR24D6-T instead - those variants add the respective features while maintaining the same 2.40V threshold and 560ms timeout.
What is the minimum supply voltage at which MAX6382XR24D6-T guarantees correct RESET output logic state?
The MAX6382XR24D6-T guarantees valid RESET output logic state down to VCC = 1.0V. Below this voltage, the internal circuitry cannot maintain defined output levels. This feature ensures deterministic μP initialization during deep brownout events common in battery-powered systems, where the supply may sag to near-dead-cell levels before recovery.
Can MAX6382XR24D6-T be used in automotive applications, and what qualification does it carry?
The MAX6382XR24D6-T is AEC-Q100 qualified for automotive use, as confirmed in the official Maxim Integrated datasheet. Its -40°C to +125°C operating temperature range, ±2.5% threshold accuracy over temperature, and robust negative-going transient immunity make it suitable for body electronics, infotainment power management, and other non-safety-critical automotive subsystems requiring high-reliability reset supervision.
What package type and footprint does MAX6382XR24D6-T use, and are land patterns available?
MAX6382XR24D6-T uses the 3-pin SC70 package (outline 21-0075) with 0.65mm pin pitch and 1.25mm × 0.85mm body size. Official land pattern number 90-0208 is published by Maxim Integrated and available at maximintegrated.com/packages. This compact footprint supports high-density PCB layouts in wearables, IoT nodes, and miniaturized industrial controls.
