Product details
Overview
MAX6388XS17D2-T from Maxim Integrated is a low-power microprocessor supervisory circuit with active-high push-pull reset output, 1.67V factory-set VCC reset threshold (±2.5% over −40°C to +125°C), 20ms 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 dual-rail embedded controllers.
For engineers reviewing the MAX6388XS17D2-T datasheet, MAX6388XS17D2-T pinout, MAX6388XS17D2-T application, or MAX6388XS17D2-T equivalent, this page delivers verified electrical parameters, SC70-4 package terminal mapping, dual-supply supervision capability, reset timing accuracy, and automotive-grade AEC-Q100 qualified alternatives.
Technical Context
The MAX6388XS17D2-T integrates a precision bandgap reference and comparator to monitor VCC against a fixed 1.67V threshold while simultaneously accepting an external voltage via RESET IN, compared to an internal 1.27V reference. Its reset assertion logic triggers on either VCC drop below 1.67V or RESET IN drop below 1.27V.
It features a 20ms minimum reset timeout period after VCC recovery, guaranteed operation down to VCC = 1V, and immunity to negative-going VCC transients up to 35µs at 100mV overdrive. The active-high push-pull RESET output drives high during reset and low otherwise, eliminating need for external pullup.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6388XS17D3-T | Same 1.67V threshold and RESET IN function, but 140ms reset timeout instead of 20ms | Suitable where longer reset hold time is required for complex power sequencing or slow-start regulators | Select when system startup requires extended reset assertion beyond 20ms |
| TLV809K33DBZR | Single-supply only (no RESET IN), 3.3V reset threshold, SOT-23-3 package, 0.5μA typical ICC | Lacks dual-monitoring capability; suited for simple 3.3V-only systems with ultra-low power priority | Choose only for cost-sensitive, single-rail applications where auxiliary monitoring is unnecessary |
Compared with MAX6388XS17D2-T, the MAX6388XS17D3-T offers longer reset hold time for demanding power-up sequences, while TLV809K33DBZR trades dual-supply capability for lower cost and sub-microamp current-making it viable only in non-dual-rail contexts.

FAQ
What is the exact reset threshold voltage of MAX6388XS17D2-T and how accurate is it over temperature?
The MAX6388XS17D2-T has a factory-set VCC reset threshold of 1.67V, with ±2.5% accuracy guaranteed over the full operating temperature range of −40°C to +125°C. This tolerance ensures reliable detection of brownout conditions in 1.8V systems even under extreme thermal stress, and is confirmed in the Electrical Characteristics table of the official datasheet.
Does MAX6388XS17D2-T support monitoring of two independent power rails?
Yes, MAX6388XS17D2-T supports dual-rail supervision: VCC monitors the primary supply (e.g., 1.8V core), while the RESET IN pin monitors a secondary rail (e.g., 3.3V I/O) via an external resistor divider referenced to its internal 1.27V comparator threshold. Both inputs independently trigger the same active-high RESET output.
What is the function and timing behavior of the RESET output on MAX6388XS17D2-T?
The RESET output of MAX6388XS17D2-T is an active-high push-pull driver. It asserts high whenever VCC falls below 1.67V or RESET IN falls below 1.27V, and remains high for a minimum of 20ms after both voltages recover above their respective thresholds. This ensures µP reset duration meets JEDEC JESD8-12E requirements.
Is MAX6388XS17D2-T qualified for automotive applications?
Yes, MAX6388XS17D2-T carries the "/V" automotive qualification suffix and is AEC-Q100 Grade 1 qualified (−40°C to +125°C). Its datasheet explicitly lists AEC-Q100 qualification in the Features section and Ordering Information table, confirming suitability for automotive body electronics and infotainment systems.
What package type and pin count does MAX6388XS17D2-T use, and is it RoHS-compliant?
MAX6388XS17D2-T uses a 4-pin SC70 package (outline 21-0098), measuring 2.0mm × 2.1mm × 0.95mm, with lead(Pb)-free/RoHS-compliant construction indicated by the "+T" suffix in the part number. The package drawing and land pattern (90-0187) are published on maximintegrated.com/packages.
