Product details
Overview
MAX6388XS16D5-T from Maxim Integrated is a low-power microprocessor supervisory circuit with active-high push-pull reset output, factory-set 1.58V VCC reset threshold (±2.5% over -40°C to +125°C), 280ms minimum reset timeout, and auxiliary RESET IN input for dual-voltage monitoring. It consumes only 3μA at +1.8V and guarantees valid reset state down to VCC = 1V, used in battery-powered instrumentation and embedded controllers requiring reliable power-on reset and brownout protection.
For engineers reviewing the MAX6388XS16D5-T datasheet, MAX6388XS16D5-T pinout, MAX6388XS16D5-T application, or MAX6388XS16D5-T equivalent, this page delivers verified electrical parameters, SC70-4 package layout, dual-supply monitoring capability, reset timing accuracy, and automotive-grade AEC-Q100 qualified alternatives - all confirmed from Maxim's official documentation.
Technical Context
The MAX6388XS16D5-T integrates a precision voltage comparator for VCC monitoring against a fixed 1.58V threshold and a separate high-impedance RESET IN comparator referenced to +1.27V, enabling user-defined secondary supply monitoring via external resistor divider. Its internal timer ensures reset assertion for exactly 280ms (min) after VCC or RESET IN recovers above threshold.
It features an active-high push-pull RESET output capable of sourcing 800µA at VCC ≥ 4.5V (VOH ≥ 0.8×VCC) and sinking 3.2mA (VOL ≤ 0.4V), with guaranteed logic validity down to VCC = 1V. The device operates across -40°C to +125°C and supports negative-going VCC transient immunity up to 35µs at 100mV overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Reset Threshold | 1.58V (nominal), ±2.5% tolerance over -40°C to +125°C - ensures consistent brownout detection across industrial temperature range |
| Reset Timeout Period | 280ms (minimum) - provides sufficient hold time for μP initialization before release |
| Supply Current | 3μA at +1.8V - enables multi-year operation in coin-cell–powered portable systems |
| RESET Output Type | Active-high push-pull - eliminates need for external pullup, reduces BOM count and board space |
| Auxiliary Input | RESET IN comparator referenced to +1.27V - supports adjustable second-supply monitoring with <50nA input leakage |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial control applications |
| VCC Range | +1.0V to +5.5V - compatible with core voltages from ultra-low-power MCUs to 5V legacy systems |
Pinout & Package
MAX6388XS16D5-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 | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Primary supply input and monitored voltage rail - powers internal circuitry and triggers reset when below 1.58V |
| 2 | RESET | Active-high push-pull output - drives high during reset assertion; sinks current when deasserted to ensure clean release |
| 3 | GND | Analog/digital ground reference - must be connected directly to system ground plane for noise immunity |
| 4 | RESET IN | Auxiliary voltage monitor input - compared to internal +1.27V reference; enables dual-rail supervision without additional ICs |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply monitoring capability | Simultaneous VCC and RESET IN supervision - eliminates need for discrete comparators in dual-voltage systems (e.g., VCORE + I/O) |
| Factory-trimmed reset threshold | 1.58V ±2.5% over full temperature range - removes calibration overhead and improves BOM consistency |
| Ultra-low quiescent current | 3μA at +1.8V - extends battery life in always-on sensor nodes and portable medical devices |
| Guaranteed reset validity to 1V | RESET output remains logic-valid down to VCC = 1V - prevents spurious release during deep brownout |
| Negative transient immunity | Withstands 35µs VCC glitches at 100mV overdrive - suppresses false resets caused by switching noise or ESD coupling |
Applications
| Industrial PLC Controller | Battery-Powered Data Logger |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6388LT16D5-T | Same electrical specs but in 6-pin µDFN (L611+1) package - larger footprint, better thermal performance (θJA = 477°C/W vs. 322.6°C/W) | Preferred for high-reliability industrial designs requiring enhanced thermal margin and solder-joint robustness | Select when board layout allows 2.5mm × 2.5mm footprint and thermal dissipation >167mW is required |
| MAX6389XS16D5-T | Identical SC70-4 package and 1.58V/280ms specs, but open-drain active-low RESET output - requires external pullup resistor | Suitable where system-level reset bus uses wired-OR topology or shares reset line with multiple devices | Choose only if existing design mandates active-low signaling or shared reset bus architecture |
Compared with MAX6388XS16D5-T, the LT version offers superior thermal management in µDFN but increases PCB area by 56%, while the XS16D5-T variant trades push-pull convenience for open-drain flexibility - neither is pin-compatible, and both require schematic and layout revision.

FAQ
What is the exact reset threshold voltage and tolerance for MAX6388XS16D5-T?
The MAX6388XS16D5-T has a factory-set VCC reset threshold of 1.58V nominal, with ±2.5% tolerance guaranteed over the full operating temperature range of -40°C to +125°C. This value is specified in the Reset Thresholds table of the datasheet (suffix "16"), and applies exclusively to the VCC monitor - the RESET IN comparator uses a separate +1.27V internal reference.
Does MAX6388XS16D5-T support manual reset functionality?
No, MAX6388XS16D5-T does not include a manual reset (MR) input. According to the Selector Guide and Pin Configurations, MR is only present on MAX6384/MAX6385/MAX6386/MAX6390 variants. The MAX6388XS16D5-T features RESET IN for auxiliary voltage monitoring but no MR pin - its reset is triggered solely by VCC or RESET IN falling below threshold.
What package type and dimensions does MAX6388XS16D5-T use?
MAX6388XS16D5-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), rated for -40°C to +125°C operation, and features a thermal resistance of θJA = 322.6°C/W on a multilayer board - confirmed in the Package Information section of the datasheet.
Can MAX6388XS16D5-T monitor two independent power rails simultaneously?
Yes, MAX6388XS16D5-T supports dual-rail monitoring: VCC is monitored against the fixed 1.58V threshold, while the RESET IN pin connects to an external resistor divider to set a user-defined second threshold (e.g., for 3.3V or 2.5V rail). The device asserts RESET if either voltage falls below its respective threshold - a key differentiator versus single-supply supervisors.
What is the guaranteed minimum reset timeout period for MAX6388XS16D5-T?
The guaranteed minimum reset timeout period for MAX6388XS16D5-T is 280ms, corresponding to the "D5" suffix in the part number. This is the duration RESET remains asserted after VCC or RESET IN rises above threshold - validated across -40°C to +125°C and specified in the Reset Timeout Delay table of the datasheet.
