Product details
Overview
MAX6383XR17D3+T from Maxim Integrated is a low-power, open-drain active-low microprocessor supervisory circuit with factory-set 1.67V reset threshold, 140ms minimum VCC reset timeout, and guaranteed operation down to VCC = 1V. It monitors single supply voltage in battery-powered or low-voltage embedded systems and asserts reset during power-up, brownout, or undervoltage conditions. Designed for space-constrained applications, it consumes only 3μA at +1.8V.
For engineers reviewing the MAX6383XR17D3+T datasheet, MAX6383XR17D3+T pinout, MAX6383XR17D3+T application, or MAX6383XR17D3+T equivalent, key selection considerations include its open-drain output requiring external pullup, ±2.5% reset threshold accuracy over –40°C to +125°C, 140ms reset timeout, 1.67V threshold, and SC70-3 package compatibility with legacy MAX809/MAX810 footprints.
Technical Context
The MAX6383XR17D3+T implements a precision bandgap-based voltage comparator with internal 1.67V reference and a monostable timer that guarantees minimum 140ms reset assertion after VCC rises above threshold. Its open-drain RESET output requires an external pullup resistor and remains valid down to VCC = 1V, enabling reliable reset signaling even during deep brownout.
No manual reset (MR) input or auxiliary RESET IN comparator is included - this variant is optimized for simple single-supply monitoring without user-initiated or dual-rail supervision. It belongs to the MAX6381–MAX6390 family but excludes MR and RESET IN features present in MAX6384–MAX6390 and MAX6387–MAX6389 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.67V (nominal), ±2.5% over –40°C to +125°C - ensures accurate undervoltage detection across automotive and industrial temperature ranges |
| Reset Timeout | 140ms (minimum) - provides sufficient hold time for μP initialization before release |
| Supply Current | 3μA at +1.8V - enables multi-year battery life in portable equipment |
| Operating Voltage | 1.0V to 5.5V - supports valid reset assertion down to 1V, critical for low-VCC brownout recovery |
| Output Type | Open-drain active-low - requires external pullup; allows wired-OR configuration and level translation |
| Package | 3-pin SC70 (X3+2 outline) - 1.25mm × 0.85mm footprint, compatible with MAX809 footprint |
| Temperature Range | –40°C to +125°C - qualified for under-hood and industrial control environments |
Pinout & Package
MAX6383XR17D3+T is housed in a 3-pin SC70 package (outline 21-0075, land pattern 90-0208), with pins arranged in a single row. The compact 1.25mm × 0.85mm body height of 0.5mm supports high-density PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Open-drain active-low reset output; must be pulled up externally; sinks ≥80µA at VCC ≥ 1.0V with VOL ≤ 0.3V |
| 2 | VCC | Power supply input and monitored rail; operates from 1.0V to 5.5V; reset asserts when VCC falls below 1.67V |
| 3 | GND | Analog ground reference; must be connected directly to system ground plane for stable threshold accuracy |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 1.67V nominal with ±2.5% tolerance over full temperature range - eliminates external resistor networks and calibration |
| Ultra-low quiescent current | 3μA at 1.8V - extends battery life in always-on IoT sensors and wearables |
| Valid reset down to VCC = 1V | Guaranteed logic state integrity during deep brownout - prevents spurious μP release before stable supply |
| Negative-going transient immunity | Rejects short VCC glitches (e.g., <1µs at 100mV overdrive) - avoids false resets in noisy power environments |
| SC70-3 footprint compatibility | Pins match MAX809/MAX810 - enables drop-in replacement without PCB redesign |
Applications
| Battery-Powered Portable Devices | Industrial Microcontroller Systems |
|---|---|
Use Scenario: Power management in handheld medical meters or wireless sensor nodes where battery voltage decays from 3.3V to 1.8V over time. IC Role / Device Role / Timing Role: Monitors main supply rail and holds μP in reset until voltage stabilizes above 1.67V during cold start or recharge. Use Value: Prevents code execution errors during weak-battery brownout; 3μA current draw minimizes standby drain. | Use Scenario: PLC I/O module operating in harsh factory environments with wide ambient temperature swings. IC Role / Device Role / Timing Role: Single-rail supervisor ensuring deterministic μC boot sequence despite 125°C junction temperatures and supply ripple. Use Value: ±2.5% threshold accuracy over –40°C to +125°C eliminates need for recalibration; SC70 package withstands reflow and thermal cycling. |
| Automotive Body Control Modules | Low-Voltage Embedded Controllers |
Use Scenario: Supervision of 1.8V or 2.5V core rails in BCM subassemblies exposed to engine bay thermal stress.

Use Value: Valid operation down to VCC = 1V ensures reset integrity during cranking-induced dips; RoHS-compliant +T package meets automotive sourcing mandates. | Use Scenario: Reset coordination in FPGA-configurable edge devices powered by buck-converted 1.2V/1.8V supplies. IC Role / Device Role / Timing Role: Simple, footprint-compatible supervisor for single-rail SoC power domains without manual reset complexity. Use Value: Open-drain output enables shared reset bus with other peripherals; 1.67V threshold matches LDO dropout margins in ultra-low-VCC designs. |
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 | Same 3-pin SC70 package, 1.63V reset threshold (±2%), 140ms timeout, push-pull active-low output | Push-pull eliminates need for external pullup; less suitable for wired-OR or level-shifted reset buses | Select when board layout lacks space for pullup resistor or when driving capacitive loads >50pF |
| TPS3808G16DBVR | 3-pin SOT-23, 1.6V threshold (±0.5%), 200ms timeout, open-drain active-low, 1.4μA typical ICC | Higher accuracy and lower current, but different footprint and no AEC-Q100 qualification | Select for ultra-low-power consumer applications where footprint conversion is acceptable and automotive qualification is not required |
Compared with MAX6383XR17D3+T, MAX809TRD3+T offers push-pull convenience at the cost of wiring flexibility, while TPS3808G16DBVR delivers tighter threshold tolerance and lower current but requires PCB redesign and lacks automotive qualification - making MAX6383XR17D3+T optimal for drop-in, robust, open-drain reset in space- and reliability-constrained designs.

FAQ
What is the exact reset threshold voltage of the MAX6383XR17D3+T?
The MAX6383XR17D3+T has a factory-set nominal reset threshold of 1.67V, with guaranteed tolerance of ±2.5% over the full operating temperature range of –40°C to +125°C. This value is confirmed in the Reset Thresholds table of the datasheet (suffix "17" corresponds to 1.62V min / 1.67V nom / 1.71V max). The threshold is internally trimmed and does not require external components.
Does the MAX6383XR17D3+T include a manual reset input (MR)?
No, the MAX6383XR17D3+T does not include a manual reset input. Per the Selector Guide and Pin Configurations, MR is only present on MAX6384–MAX6386 and MAX6390 variants. The MAX6383XR17D3+T is a dedicated single-supply supervisor with RESET, VCC, and GND pins only - no MR or RESET IN functionality is implemented.
What package type and dimensions does the MAX6383XR17D3+T use?
The MAX6383XR17D3+T uses a 3-pin SC70 package (outline number 21-0075, land pattern 90-0208), measuring 1.25mm × 0.85mm with a maximum height of 0.5mm. Its pinout is identical to the MAX809 series, enabling direct footprint compatibility and simplified migration in existing designs.
Can the MAX6383XR17D3+T operate reliably below 1.8V supply?
Yes, the MAX6383XR17D3+T is fully specified to operate from VCC = 1.0V to 5.5V. Its reset output remains valid down to VCC = 1.0V, and supply current is characterized at 1.8V (3μA), 2.5V (4μA), and 3.6V (6μA). This makes it suitable for brownout detection in systems powered by depleting batteries or low-dropout regulators.
Is the MAX6383XR17D3+T qualified for automotive applications?
The base MAX6383XR17D3+T is not automotive-qualified; however, the /V variant (e.g., MAX6383XR17D3/V+T) is AEC-Q100 qualified for automotive use. The +T suffix indicates RoHS-compliant packaging, but automotive qualification requires explicit /V in the part number - confirmed in the Ordering Information table and Package Information section.
