Product details
Overview
MAX6384XS17D3-T from Maxim Integrated is a low-power microprocessor supervisory circuit with factory-set 1.67V reset threshold, 140ms minimum VCC reset timeout, and active-low push-pull reset output. It monitors +1.8V to +5.0V supply rails, consumes only 3μA at +1.8V, and guarantees valid reset state down to VCC = 1V. Used in portable battery-powered equipment for reliable power-up sequencing and brownout protection.
For engineers reviewing the MAX6384XS17D3-T datasheet, MAX6384XS17D3-T pinout, MAX6384XS17D3-T application, or MAX6384XS17D3-T equivalent, key selection criteria include reset threshold accuracy (±2.5% over –40°C to +125°C), manual reset input with internal 63kΩ pullup, 4-pin SC70 package footprint, and immunity to negative-going VCC transients.
Technical Context
The MAX6384XS17D3-T implements a precision voltage comparator with ±2.5% threshold accuracy across –40°C to +125°C, paired with a monolithic timer that enforces a guaranteed-minimum 140ms reset assertion after VCC recovers above 1.67V. Its reset logic asserts on VCC drop below threshold or MR pin low, and deasserts only after full timeout elapses - no windowed or retriggerable behavior.
This device uses a dedicated manual reset input (MR) with internal 63kΩ pullup resistor, supporting TTL/CMOS-compatible logic levels and requiring no external debounce. Unlike MAX6390, it does not feature separate VCC/manual reset timeout periods - both use the same D3 (140ms) delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.67V nominal (±2.5% over –40°C to +125°C); ensures reliable detection of 1.8V rail brownout |
| VCC Reset Timeout | 140ms minimum; holds μP in reset long enough for stable clock and supply settling |
| Supply Current | 3μA at +1.8V; enables multi-year operation in coin-cell–powered IoT sensors |
| Operating Voltage | +1.0V to +5.5V; supports valid reset assertion even during deep brownout (down to 1V) |
| Reset Output Type | Active-low push-pull; drives reset line directly without external pullup, compatible with standard μP reset inputs |
| Manual Reset Input | MR with 63kΩ internal pullup; allows momentary switch-to-GND reset initiation without external components |
| Package | 4-pin SC70 (X4+1 outline); 1.6mm × 1.6mm footprint, suitable for space-constrained portable designs |
Pinout & Package
MAX6384XS17D3-T is housed in a RoHS-compliant 4-pin SC70 package (outline 21-0098, land pattern 90-0187), with 0.65mm pitch and thermal resistance θJA = 322.6°C/W on multilayer board.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Main supply input; powers internal circuitry and serves as monitored voltage source for fixed-threshold reset |
| 2 | RESET | Active-low push-pull output; sinks current when asserted, sources current when deasserted; no external pullup required |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC via 63kΩ resistor; initiates reset when pulled low |
| 4 | GND | Analog/digital ground reference; must be connected to system ground plane for accurate threshold sensing |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 1.67V with ±2.5% tolerance over full temperature range - eliminates need for external resistor dividers |
| Dedicated manual reset input | MR pin with integrated 63kΩ pullup enables single-switch reset without BOM additions or layout overhead |
| Low quiescent current | 3μA at +1.8V allows integration into always-on battery-backed systems with >10-year shelf life |
| VCC-operated reset guarantee | Valid RESET output state maintained down to VCC = 1V - critical for graceful shutdown in ultra-low-voltage systems |
| Negative transient immunity | Immune to short-duration VCC glitches (e.g., <1µs at 100mV overdrive), reducing false resets in noisy environments |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6384XS17D3+T | Same electrical specs and pinout; differs only in RoHS compliance marking (+T suffix denotes lead-free, non-automotive grade) | No functional difference; identical performance in commercial-temperature industrial designs | Select MAX6384XS17D3+T for cost-sensitive non-automotive production where AEC-Q100 qualification is unnecessary |
| TLV809K16DBVR | 1.6V threshold (vs. 1.67V), 140ms timeout, SOT-23-3 package; no MR input; 0.5μA lower ICC at 1.8V | Lacks manual reset capability; requires external pullup for reset output; smaller footprint but no MR functionality | Choose TLV809K16DBVR only when MR is unused and board space is constrained - trade-off is loss of field-service reset capability |
Compared with MAX6384XS17D3-T, the +T variant offers identical performance at lower cost for non-automotive use, while TLV809K16DBVR sacrifices MR functionality and push-pull drive to achieve lower current and smaller size - making it suitable only for simplified reset-only applications.

FAQ
What is the exact reset threshold voltage of MAX6384XS17D3-T?
The MAX6384XS17D3-T has a factory-set nominal reset threshold of 1.67V, with guaranteed tolerance of ±2.5% over the full operating temperature range (–40°C to +125°C). This value is laser-trimmed during production and documented in the Reset Thresholds table of the MAX6381–MAX6390 datasheet. The '17' suffix in the part number explicitly denotes the 1.67V threshold variant.
Does MAX6384XS17D3-T support manual reset functionality?
Yes, MAX6384XS17D3-T includes a dedicated active-low manual reset input (MR pin) with an internal 63kΩ pullup resistor to VCC. Driving MR low forces reset assertion for the full 140ms timeout period, then holds reset active for the same duration after MR is released. This eliminates the need for external pullup components and supports direct connection to momentary switches or logic signals.
What package type and dimensions does MAX6384XS17D3-T use?
MAX6384XS17D3-T is packaged in a 4-pin SC70 (X4+1 outline), measuring 1.6mm × 1.6mm with 0.65mm pin pitch. This RoHS-compliant package has thermal resistance θJA = 322.6°C/W on a multilayer PCB and is distinct from the 3-pin SC70 used by MAX6381–MAX6383 or the 6-pin μDFN used by LT-suffixed variants.
How does the reset timeout behavior work on MAX6384XS17D3-T?
MAX6384XS17D3-T provides a fixed 140ms minimum reset timeout (D3 suffix) triggered either by VCC falling below 1.67V or by pulling MR low. The reset output remains asserted for the full 140ms after VCC rises above threshold or MR is released - it is not retriggerable during timeout and does not shorten if VCC recovers rapidly. This ensures deterministic reset hold time for all supported microcontrollers.
Is MAX6384XS17D3-T qualified for automotive applications?
No, MAX6384XS17D3-T is not AEC-Q100 qualified. The '/V' suffix (e.g., MAX6384XS17D3/V+T) indicates automotive qualification; this part lacks that designation. It is rated for –40°C to +125°C operation but does not meet the additional stress testing, traceability, and documentation requirements of AEC-Q100 Grade 2. For automotive use, specify the /V version instead.
