Product details
Overview
The MAX6388XS16D6-T from Maxim Integrated is a low-power, single-supply microprocessor supervisory circuit with active-high push-pull reset output, 1.58V factory-set reset threshold, and 560ms minimum VCC reset timeout period. It monitors VCC from +1.0V to +5.5V, consumes only 3μA at +1.8V, and guarantees valid reset state down to VCC = 1V. It features an auxiliary RESET IN input for dual-voltage monitoring and operates across –40°C to +125°C - used in battery-powered instrumentation and industrial controllers requiring reliable brownout detection.
For engineers reviewing the MAX6388XS16D6-T datasheet, MAX6388XS16D6-T pinout, MAX6388XS16D6-T application, or MAX6388XS16D6-T equivalent, key selection criteria include its 1.58V reset threshold accuracy (±2.5% over temperature), 4-pin SC70 package footprint, dual-monitoring capability via RESET IN, and compatibility with systems requiring active-high reset assertion without external pullup.
Technical Context
The MAX6388XS16D6-T integrates a precision voltage comparator referenced to an internal 1.27V bandgap for the auxiliary RESET IN input, enabling user-defined secondary voltage monitoring via external resistor divider. Its primary VCC reset comparator uses a factory-trimmed threshold of 1.58V with ±2.5% tolerance over –40°C to +125°C and 60ppm/°C tempco.
It employs a digital timeout timer that asserts RESET for ≥560ms after VCC rises above 1.58V or after RESET IN recovers; RESET remains high during assertion. The device supports negative-going VCC transient immunity up to 150µs for 100mV overdrive and guarantees correct logic state for VCC ≥ 1V - critical for low-voltage power sequencing in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V (factory-set, ±2.5% over –40°C to +125°C) - ensures deterministic brownout detection at ultra-low supply voltages. |
| VCC Operating Range | +1.0V to +5.5V - supports operation down to near-dead-battery conditions while interfacing with 1.8V/2.5V/3.3V/5V rails. |
| Reset Timeout Period | 560ms minimum - provides sufficient hold time for microcontroller initialization and peripheral stabilization. |
| Supply Current | 3μA at +1.8V - enables multi-year battery life in always-on sensor nodes and portable medical devices. |
| RESET Output Type | Active-high push-pull - eliminates need for external pullup resistor and drives CMOS/TTL loads directly. |

Pinout & Package
MAX6388XS16D6-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 PCB layouts in portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Main supply input and primary voltage monitor - powers internal circuitry and triggers reset when falling below 1.58V. |
| 2 | RESET | Active-high push-pull output - drives high during reset assertion; sinks/source current per spec without external components. |
| 3 | GND | Analog/digital ground reference - must be connected to system ground plane for accurate threshold sensing and noise immunity. |
| 4 | RESET IN | Auxiliary voltage monitor input - compared to internal 1.27V reference; enables dual-rail supervision (e.g., core + I/O supplies). |
Key Features
| Feature | Design Value |
|---|---|
| Dual-voltage supervision | Simultaneous monitoring of VCC and external rail via RESET IN - eliminates need for second supervisor IC in dual-supply systems. |
| Low-voltage operation guarantee | Valid RESET output state ensured down to VCC = 1V - enables robust reset signaling during deep brownout or battery sag. |
| Negative transient immunity | Rejects VCC glitches ≤150µs wide at 100mV overdrive - prevents spurious resets in electrically noisy environments. |
| Factory-trimmed accuracy | ±2.5% reset threshold tolerance over full temperature range - reduces system-level calibration burden in production test. |
| Ultra-low quiescent current | 3μA at +1.8V - extends battery runtime in IoT edge sensors and wearable health monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6385XS16D6-T | Same 1.58V threshold and 560ms timeout, but includes manual reset (MR) input - no RESET IN. | Suitable where operator-initiated reset is required instead of dual-voltage monitoring. | Select MAX6385XS16D6-T if manual reset functionality is needed and auxiliary voltage supervision is not. |
| TPS3808G16DBVR | 1.6V threshold (±0.5%), 550ms timeout, SOT-23-5 package; requires external pullup for open-drain RESET. | Lacks auxiliary input; offers tighter threshold accuracy but no dual-rail capability. | Choose TPS3808G16DBVR when higher threshold precision is prioritized over dual-supply monitoring and board space permits SOT-23-5. |
Compared with MAX6385XS16D6-T, MAX6388XS16D6-T trades manual reset for auxiliary voltage supervision - making it optimal for dual-rail systems without physical reset buttons. Against TPS3808G16DBVR, it provides integrated dual-monitoring and push-pull output in a smaller SC70 footprint, albeit with looser threshold tolerance.

FAQ
What is the exact reset threshold voltage of the MAX6388XS16D6-T?
The MAX6388XS16D6-T has a factory-set reset threshold of 1.58V, with guaranteed accuracy of ±2.5% over the full operating temperature range of –40°C to +125°C. This value is laser-trimmed during production and documented in the Reset Thresholds table of the datasheet. The MAX6388XS16D6-T does not support adjustable thresholds - the "16" suffix explicitly denotes the 1.58V variant.
Does the MAX6388XS16D6-T support dual-voltage monitoring, and how is it implemented?
Yes, the MAX6388XS16D6-T supports dual-voltage monitoring via its dedicated RESET IN pin, which compares an external voltage to an internal 1.27V reference. To supervise a second rail (e.g., 3.3V I/O supply), connect a resistor divider between that rail and GND, feeding the midpoint to RESET IN. The MAX6388XS16D6-T asserts reset if either VCC falls below 1.58V or the voltage at RESET IN drops below 1.27V.
What is the function of the RESET output on the MAX6388XS16D6-T, and what drive capability does it have?
On the MAX6388XS16D6-T, the RESET output is an active-high push-pull driver - it drives high during reset assertion and low otherwise. It sources up to 800µA at VCC ≥ 4.5V and sinks up to 3.2mA when asserted, eliminating the need for an external pullup resistor. This differs from open-drain variants and ensures direct TTL/CMOS compatibility without additional components.
Can the MAX6388XS16D6-T operate reliably at very low supply voltages, and down to what level?
Yes, the MAX6388XS16D6-T guarantees correct RESET output logic state down to VCC = 1.0V, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables. Its internal circuitry remains functional and the reset comparator maintains accuracy even at this low voltage - critical for applications like battery-powered devices experiencing deep discharge or brownout conditions.
What package type and footprint does the MAX6388XS16D6-T use, and are there thermal considerations?
The MAX6388XS16D6-T uses a 4-pin SC70 package (outline 21-0098, land pattern 90-0187), measuring 2.0mm × 2.1mm × 0.95mm. Its junction-to-ambient thermal resistance (θJA) is 322.6°C/W on a multilayer board. For continuous operation at +125°C ambient, power dissipation must remain below 245mW - well within its typical 3μA supply current at +1.8V (≈5.4nW), making thermal design straightforward.
