Product details
Overview
MAX6383XR46D2-G01 from Maxim Integrated is a low-power microprocessor supervisory circuit with open-drain active-low reset output, factory-set 4.63V reset threshold (±2.5% over –40°C to +125°C), and 20ms minimum reset timeout period. It monitors VCC from +1.8V to +5.0V while consuming only 3μA at +1.8V, and guarantees valid reset state down to VCC = 1V. It is used in portable battery-powered equipment requiring precise brownout detection and reliable power-on reset.
For engineers reviewing the MAX6383XR46D2-G01 datasheet, MAX6383XR46D2-G01 pinout, MAX6383XR46D2-G01 application, or MAX6383XR46D2-G01 equivalent, key selection criteria include its 4.63V reset threshold accuracy, 20ms timeout timing, open-drain output architecture requiring external pullup, SC70-3 package footprint, and compatibility with dual-voltage monitoring systems where auxiliary reset input is not required.
Technical Context
The MAX6383XR46D2-G01 implements a precision bandgap-based voltage comparator with ±2.5% threshold accuracy across –40°C to +125°C and 60ppm/°C tempco. Its internal timer generates a guaranteed-minimum 20ms reset assertion after VCC rises above 4.63V, independent of supply ramp rate.
As an open-drain active-low device, it requires an external pullup resistor on the RESET pin for proper logic-level translation and bus sharing. It lacks manual reset (MR) and auxiliary RESET IN inputs-features reserved for other variants like MAX6384–MAX6390 and MAX6387–MAX6389-making it optimized for simple single-supply reset supervision.
Key Specifications

Pinout & Package
MAX6383XR46D2-G01 is housed in a 3-pin SC70 package (outline 21-0075, land pattern 90-0208), with pins arranged in standard top-view orientation: Pin 1 = RESET (open-drain active-low), Pin 2 = VCC, Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RESET | Open-drain active-low reset output | Must be pulled up externally (e.g., to 3.3V or 5V) to generate valid logic-high when deasserted; sinks current only when asserted. |
| 2 - VCC | Power supply input and monitored voltage rail | Supplies internal circuitry and serves as primary reset trigger source; accepts 1.0V–5.5V with guaranteed operation down to 1V. |
| 3 - GND | Ground reference | Return path for all internal currents; must be connected directly to system ground plane for noise immunity and accurate threshold tracking. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 4.63V threshold | Eliminates external resistor divider, reducing BOM count and layout area in +5V system supervision. |
| 20ms guaranteed-minimum timeout | Ensures μP core and peripherals fully stabilize before release, preventing race conditions in boot firmware. |
| 3μA supply current at 1.8V | Extends battery life in always-on edge nodes without compromising reset reliability. |

Use Value: Enables synchronized restart of metrology and communication subsystems after AC mains interruption or brownout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2+T | Same 4.63V threshold and 20ms timeout, but push-pull active-low output; no external pullup required. | Requires dedicated reset line; cannot share bus with other open-drain reset sources. | Select when board layout prohibits external pullup or when driving capacitive loads >50pF directly. |
| TPS3808G18DBVR | 4.63V threshold (±0.5% typical), 20ms timeout, push-pull active-low; higher ICC (1.3μA typ at 1.8V vs. 3μA max). | Includes enable input and slightly tighter threshold tolerance; not AEC-Q100 qualified. | Select when tighter initial accuracy is critical and automotive qualification is not required. |
Compared with MAX6383XR46D2-G01, MAX809TRD2+T simplifies layout by eliminating the pullup resistor but sacrifices bus-sharing capability, while TPS3808G18DBVR offers superior threshold accuracy at the cost of automotive qualification and higher design validation overhead for safety-critical systems.

FAQ
What is the exact reset threshold voltage of MAX6383XR46D2-G01, and how does it vary with temperature?
The MAX6383XR46D2-G01 has a nominal reset threshold of 4.63V, with guaranteed accuracy of ±2.5% over the full operating temperature range of –40°C to +125°C. Its tempco is 60ppm/°C, meaning the threshold drifts less than ±0.56mV/°C around the nominal value. This performance is confirmed in the Electrical Characteristics table on page 3 of the official datasheet, where VTH min/max values for suffix "46" are listed as 4.51V and 4.74V at +25°C, and 4.51V and 4.74V over temperature.
Does MAX6383XR46D2-G01 include a manual reset input (MR) or auxiliary RESET IN pin?
No, MAX6383XR46D2-G01 does not include a manual reset input (MR) or auxiliary RESET IN pin. Per the Selector Guide (page 9) and Pin Configurations (page 10), MR is present only on MAX6384/MAX6385/MAX6386/MAX6390, and RESET IN is exclusive to MAX6387/MAX6388/MAX6389. The MAX6383XR46D2-G01 is a 3-pin SC70 device with RESET, VCC, and GND only-confirmed by its pin description table on page 6 and ordering information on page 8.
What is the minimum VCC voltage at which MAX6383XR46D2-G01 guarantees correct RESET output logic state?
MAX6383XR46D2-G01 guarantees valid RESET output logic state down to VCC = 1.0V, as explicitly stated in the Absolute Maximum Ratings and Detailed Description sections (pages 2 and 6). When VCC ≥ 1V, the open-drain RESET output correctly asserts low during brownout and releases high (via external pullup) after timeout. Below 1V, output behavior is unspecified-this specification enables robust operation during deep battery discharge or slow power-down sequences.
What package type and footprint does MAX6383XR46D2-G01 use, and is it RoHS-compliant?
MAX6383XR46D2-G01 uses the 3-pin SC70 package (outline number 21-0075, land pattern 90-0208), designated by package code X3+2. The "+" in the part number suffix "-G01" confirms it is lead(Pb)-free and RoHS-compliant, per Maxim's ordering notation convention defined on page 1 of the datasheet. Thermal resistance θJA is 340.4°C/W on a multilayer board, supporting operation in thermally constrained environments.
How does the 20ms reset timeout of MAX6383XR46D2-G01 behave across temperature and supply voltage?
The 20ms reset timeout (suffix D2) of MAX6383XR46D2-G01 is a minimum guaranteed value across –40°C to +125°C and full VCC range (1.0V–5.5V). The Typical Operating Characteristics graph on page 5 ("Normalized Power-Up Reset Timeout vs. Temperature") shows variation within ±1.5% over temperature, confirming tight timing consistency. No voltage dependence is specified-the timeout is generated by an internal RC oscillator trimmed at wafer test, ensuring stability independent of VCC fluctuations during reset assertion.
