Product details
Overview
MAX6384XS23D3-T from Maxim Integrated is a low-power microprocessor supervisory circuit with active-low push-pull reset output, factory-set 2.31V reset threshold (±2.5% over -40°C to +125°C), 140ms minimum VCC reset timeout, and debounced manual reset input (MR) with internal 63kΩ pullup. It monitors single supply voltage in battery-powered controllers and portable instrumentation requiring reliable power-on reset under brownout conditions.
For engineers reviewing the MAX6384XS23D3-T datasheet, MAX6384XS23D3-T pinout, MAX6384XS23D3-T application, or MAX6384XS23D3-T equivalent, key selection criteria include reset threshold accuracy at temperature extremes, MR pulse immunity (100ns glitch rejection), guaranteed valid reset state down to VCC = 1V, and compatibility with 4-pin SC70 layout constraints.
Technical Context
The MAX6384XS23D3-T implements a precision bandgap-based reset comparator with ±2.5% threshold tolerance across -40°C to +125°C and 60ppm/°C tempco. Its internal timer generates a fixed 140ms minimum reset assertion period after VCC recovers above 2.31V.
It features a dedicated MR input with 1µs minimum pulse width requirement, 200ns MR-to-reset delay, and internal pullup - eliminating external components for manual reset functionality. The push-pull active-low RESET output drives logic-compatible loads with VOL ≤ 0.3V at ISINK = 1.2mA (VCC ≥ 2.5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.31V (nominal), ±2.5% over -40°C to +125°C - ensures accurate brownout detection across automotive/industrial temperature range |
| VCC Reset Timeout | 140ms (min) - guarantees sufficient processor hold time during supply recovery |
| Supply Current | 3μA at +1.8V, 6μA at +3.6V - enables multi-year operation in coin-cell–powered devices |
| MR Input Pullup | 63kΩ - allows direct connection of momentary switch to GND without external resistor |
| Reset Output Type | Active-low push-pull - eliminates need for external pullup and supports direct interface to µP reset pin |
| Operating Voltage Range | 1.0V to 5.5V - supports valid reset assertion even during deep brownout (down to 1V) |
| Reset Comparator Immunity | Negative-going VCC transients < 35µs at 100mV overdrive - suppresses false resets from switching noise |
Pinout & Package
MAX6384XS23D3-T is housed in a RoHS-compliant 4-pin SC70 package (outline 21-0098, land pattern 90-0187), measuring 2.0mm × 2.1mm × 0.95mm, optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary supply input and monitored voltage rail; powers internal circuitry and reset comparator |
| 2 | RESET | Active-low push-pull reset output; sinks current when asserted, high-impedance when deasserted |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC; initiates reset on logic-low transition |
| 4 | GND | Analog/digital ground reference; must be connected to system ground plane for stable threshold operation |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 2.31V with ±2.5% accuracy over full industrial temperature range - eliminates external resistor divider calibration |
| Debounced manual reset input | 100ns glitch rejection and 1µs minimum pulse width - enables direct switch interface without RC filtering |
| Low-voltage operation guarantee | Valid RESET output state maintained down to VCC = 1.0V - ensures deterministic behavior during deep brownout |
| Ultra-low quiescent current | 3μA at 1.8V - extends battery life in always-on monitoring applications |
| Transient-immune reset comparator | Rejects negative VCC glitches < 35µs duration at 100mV overdrive - prevents false resets in noisy power environments |

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 | 2.32V reset threshold, 240ms timeout, no MR input, 3-pin SC70 | Lacks manual reset capability; requires external switch circuitry if reset-on-demand needed | Select when board space is critical and manual reset is unnecessary |

FAQ
What is the exact reset threshold voltage of MAX6384XS23D3-T and how does it vary with temperature?
The MAX6384XS23D3-T has a nominal reset threshold of 2.31V, with guaranteed tolerance of ±2.5% over the full operating range of -40°C to +125°C. Its tempco is 60ppm/°C, meaning threshold drift is bounded and predictable. This specification is confirmed in the Electrical Characteristics table of the official datasheet, where VTH min/max values for suffix "23" are listed as 2.26V/2.37V at +25°C and 2.21V/2.37V over temperature.
Does MAX6384XS23D3-T support manual reset, and what are the electrical requirements for the MR pin?
Yes, MAX6384XS23D3-T includes a debounced manual reset input (MR) with an internal 63kΩ pullup resistor to VCC. To assert reset, MR must be driven below 0.3×VCC (for VTH < 4V). It accepts TTL/CMOS logic levels and requires a minimum pulse width of 1µs. Glitch rejection is 100ns, and MR-to-reset delay is 200ns - all verified in the Electrical Characteristics section of the MAX6381–MAX6390 datasheet.
What package type and footprint does MAX6384XS23D3-T use, and is it RoHS-compliant?
MAX6384XS23D3-T uses a 4-pin SC70 package (outline number 21-0098, land pattern 90-0187), measuring 2.0mm × 2.1mm × 0.95mm. The "+T" suffix confirms it is lead(Pb)-free and RoHS-compliant. Thermal resistance θJA is 322.6°C/W on a multilayer board, per JEDEC JESD51-7 testing methodology documented in the Package Information section.
Can MAX6384XS23D3-T operate reliably at very low supply voltages, and what is its minimum functional VCC?
Yes, MAX6384XS23D3-T guarantees valid reset output state down to VCC = 1.0V, as specified in Absolute Maximum Ratings and Electrical Characteristics. Its supply current remains stable (3μA typ. at 1.8V), and RESET output VOL stays ≤0.3V at ISINK = 1.2mA even when VCC = 2.5V - ensuring interoperability with 1.8V/2.5V/3.3V microcontrollers during brownout recovery.
How does the reset timeout behavior differ between VCC recovery and manual reset release on MAX6384XS23D3-T?
MAX6384XS23D3-T provides identical 140ms minimum timeout for both VCC recovery and MR release - unlike MAX6390 which separates these delays. When VCC rises above 2.31V or MR transitions high, the RESET output remains asserted for ≥140ms before deassertion. This uniform timing simplifies system-level timing budgeting and is confirmed in the Reset Timeout Period table for D3 suffix under MAX6384 device row.
