Product details
Overview
MAX6388XS30D6-T from Maxim Integrated is a low-power, single-supply microprocessor supervisory circuit with active-high push-pull reset output, factory-set 3.00V reset threshold (±2.5% over -40°C to +125°C), 560ms minimum VCC reset timeout, and auxiliary RESET IN input for dual-voltage monitoring. It operates from +1.0V to +5.5V supply and consumes only 3μA at +1.8V, targeting power-critical embedded systems requiring reliable brownout detection.
For engineers reviewing the MAX6388XS30D6-T datasheet, MAX6388XS30D6-T pinout, MAX6388XS30D6-T application, or MAX6388XS30D6-T equivalent, key selection criteria include its 3.00V reset threshold accuracy, 560ms reset timeout, 4-pin SC70 package footprint, dual-monitoring capability via RESET IN, and guaranteed reset validity down to VCC = 1V.
Technical Context
The MAX6388XS30D6-T integrates a precision voltage comparator for VCC monitoring and a separate +1.27V reference-based comparator for the auxiliary RESET IN pin, enabling independent monitoring of two power rails. Its internal timer ensures reset assertion remains active for ≥560ms after VCC or RESET IN recovers above their respective thresholds.
It features an active-high push-pull RESET output that transitions high during fault conditions (VCC < 3.00V or RESET IN < 1.27V) and guarantees correct logic state down to VCC = 1V. The device includes negative-going VCC transient immunity and supports external resistor-divider configuration on RESET IN to set custom secondary thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.00V ±2.5% over -40°C to +125°C - ensures accurate brownout detection across automotive/industrial temperature range |
| VCC Operating Range | +1.0V to +5.5V - supports ultra-low-voltage logic and legacy 5V systems |
| Reset Timeout | 560ms minimum - provides sufficient hold time for μP initialization and peripheral stabilization |
| Supply Current | 3μA at +1.8V - enables multi-year battery life in portable equipment |
| RESET Output Type | Active-high push-pull - eliminates need for external pullup resistor and simplifies interface to μP reset input |
| Auxiliary Input | RESET IN with +1.27V reference - allows monitoring of second voltage rail (e.g., I/O supply) using external resistor divider |
| Reset Validity | Guaranteed down to VCC = 1V - ensures deterministic reset behavior during deep brownout or power ramp-down |
Pinout & Package
The MAX6388XS30D6-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, suitable for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Main supply input and primary voltage monitor source; powers internal circuitry and sets reset threshold reference point |
| 2 | RESET | Active-high push-pull output; drives high during reset condition (VCC < 3.00V or RESET IN < 1.27V); sinks/source current per spec |
| 3 | GND | Analog/digital ground reference; must be connected to system ground plane for stable comparator operation |
| 4 | RESET IN | High-impedance auxiliary input; compared against internal +1.27V reference; used to monitor second voltage rail via external resistor divider |
Key Features
| Feature | Design Value |
|---|---|
| Dual-voltage supervision | Simultaneous monitoring of VCC and external rail via RESET IN enables robust dual-supply systems (e.g., core + I/O) |
| Factory-trimmed threshold | 3.00V ±2.5% over full temperature range eliminates need for external calibration or trimming components |
| Negative transient immunity | Immune to short-duration VCC glitches below threshold - prevents spurious resets in noisy power environments |
| Low-voltage operation | Functional reset assertion down to VCC = 1V ensures reliability during deep brownout or battery depletion |
| Small-footprint packaging | 4-pin SC70 (2.0mm × 2.1mm) reduces board area by >50% vs. traditional SOT-23 solutions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6388LT30D6-T | Same electrical specs but in 6-pin μDFN package (1.5mm × 1.5mm); no SC70 footprint compatibility | Preferred for higher-density layouts where thermal performance (θJA = 477°C/W) or solder joint reliability is prioritized | Select when board space allows larger package and enhanced thermal dissipation is required |
| TPS3808G30DBVR | 3.0V threshold, 560ms timeout, but active-low open-drain output; requires external pullup; 6μA ICC at 1.8V | Suitable for systems with existing open-drain reset buses; less suitable for direct replacement due to polarity and drive architecture | Choose only if system design mandates open-drain reset signaling or TI ecosystem alignment |
Compared with MAX6388XS30D6-T, the LT30D6 variant offers identical supervision functionality in a thermally superior μDFN package but requires PCB redesign, while the TPS3808G30DBVR provides comparable timing and threshold but demands level-shifting and adds quiescent current overhead.

FAQ
What is the exact reset threshold voltage of the MAX6388XS30D6-T?
The MAX6388XS30D6-T has a factory-set reset threshold of 3.00V, with guaranteed accuracy 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 "30") and applies specifically to the VCC monitor path. The auxiliary RESET IN input uses a fixed +1.27V internal reference.
Does the MAX6388XS30D6-T support manual reset functionality?
No, the MAX6388XS30D6-T does not include a manual reset (MR) input. Per the Selector Guide and Pin Configurations, MR is present only on MAX6384/MAX6385/MAX6386/MAX6390 variants. The MAX6388XS30D6-T is designated as a dual-monitoring device with RESET IN but no MR pin - its reset assertion is triggered solely by VCC falling below 3.00V or RESET IN falling below +1.27V.
What package type and dimensions does the MAX6388XS30D6-T use?
The MAX6388XS30D6-T uses a 4-pin SC70 package (outline number 21-0098, land pattern 90-0187), measuring 2.0mm × 2.1mm × 0.95mm. It is RoHS-compliant (+T suffix) and rated for -40°C to +125°C operation. This compact footprint is distinct from the 6-pin μDFN option (e.g., MAX6388LT30D6-T) and incompatible with 3-pin SC70 variants.
How does the RESET IN pin function on the MAX6388XS30D6-T?
The RESET IN pin on the MAX6388XS30D6-T connects to an internal +1.27V reference comparator. When the voltage at this pin falls below +1.27V, it triggers reset assertion alongside VCC monitoring. Users configure a resistor divider between the secondary supply rail and GND to set the effective threshold using the formula VINTH = 1.27V × (R1/R2 + 1), enabling flexible dual-rail supervision without additional ICs.
Is the MAX6388XS30D6-T qualified for automotive applications?
The MAX6388XS30D6-T itself is not automotive-qualified; it lacks the "/V" suffix indicating AEC-Q100 qualification. Automotive-grade versions exist (e.g., MAX6388XS30D6/V+T), but the "-T" suffix denotes standard commercial/industrial temperature grade (-40°C to +125°C) with RoHS compliance. For automotive deployment, the /V variant must be specified and sourced separately.
