Product details
Overview
MAX6360SYUT-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with active-low push-pull reset output referenced to VCC2, 2.93V VCC1 threshold, 2.19V VCC2 threshold, 20µA supply current, and integrated watchdog timer featuring 46.4s startup and 2.9s normal timeout periods-designed for reliable power monitoring in multivoltage embedded systems.
For engineers reviewing the MAX6360SYUT-T datasheet, MAX6360SYUT-T pinout, MAX6360SYUT-T application, or MAX6360SYUT-T equivalent, this page delivers verified electrical parameters, exact SOT23-6 pin mapping, real-world use cases in portable equipment and intelligent instruments, and two validated alternative parts with documented functional and application differences.
Technical Context
The MAX6360SYUT-T monitors two independent supply rails (VCC1 and VCC2), asserting reset when either drops below its factory-trimmed threshold-2.93V for VCC1 and 2.19V for VCC2-with guaranteed reset validity down to VCC1 ≥ 1.0V or VCC2 ≥ 1.0V. Its watchdog timer operates in dual-mode: 46.4s startup timeout enables full system initialization, followed by 2.9s normal timeout for rapid fault detection.
It features a debounced TTL/CMOS-compatible manual-reset input (MR), no external components required for dual-rail supervision, and push-pull RST2 output referenced to VCC2-eliminating need for external pull-up resistors. All specifications are fully guaranteed over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 2.93V ±0.05V at +25°C; ensures precise reset assertion for +3.0V nominal supplies |
| VCC2 Threshold | 2.19V ±0.03V at +25°C; supports accurate monitoring of +2.5V or +2.2V rails |
| Supply Current | 20µA typical; enables ultra-low-power operation in battery-backed systems |
| Reset Timeout | 100ms minimum; guarantees sufficient processor reset hold time after power stabilization |
| Watchdog Startup Timeout | 46.4s; allows extended boot sequences before watchdog enforcement begins |
| Watchdog Normal Timeout | 2.9s; provides fast response to processor lockup during runtime |
| Operating Temperature | –40°C to +85°C; qualified for industrial and automotive-adjacent embedded environments |
Pinout & Package
MAX6360SYUT-T is housed in a 6-pin SOT23 package (U6-1 outline, land pattern 90-0175), with 0.95mm pitch, 2.9mm × 1.6mm footprint, and RoHS-compliant lead(Pb)-free construction (suffix "+T" denotes lead-free; "-T" is standard).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST2 | Active-low push-pull reset output referenced to VCC2; drives low without external pull-up |
| 2 | GND | Ground reference for all internal circuits and reset output logic |
| 3 | MR | Debounced manual-reset input; falling edge forces reset; internally pulled up (~63.5kΩ) |
| 4 | VCC2 | Secondary supply input and monitored rail; powers device when > VCC1; threshold = 2.19V |
| 5 | WDI | Watchdog input; rising/falling edges reset timer; unconnected disables watchdog |
| 6 | VCC1 | Primary supply input and monitored rail; powers device when > VCC2; threshold = 2.93V |
Key Features
| Feature | Design Value |
|---|---|
| Dual-voltage precision monitoring | Factory-trimmed 2.93V/2.19V thresholds with <20ppm/°C tempco-enables stable reset across temperature without calibration |
| Integrated dual-mode watchdog | 46.4s startup + 2.9s normal timeout eliminates need for external timing components or firmware workarounds |
| Push-pull RST2 referenced to VCC2 | Eliminates external pull-up resistor and ensures clean, rail-to-rail reset signaling for VCC2-synchronous logic |
| Guaranteed reset validity to 1.0V | Ensures deterministic reset behavior even during brownout conditions where VCC1 or VCC2 falls to 1.0V |
| No external components required | Self-contained dual-supply supervision-no capacitors, resistors, or diodes needed for basic operation |
Applications
| Portable/Battery-Powered Equipment | Intelligent Instruments |
|---|---|
Use Scenario: Battery-powered handheld meters with dual-core processors requiring independent +3.0V and +2.2V rails. IC Role / Device Role / Timing Role: Supervises both rails and asserts RST2 to halt CPU execution if either supply sags below threshold; watchdog monitors firmware execution post-boot. Use Value: Prevents corrupted memory writes and sensor misreads during battery voltage decay-extends usable runtime while ensuring safe shutdown. |
Use Scenario: Lab-grade digital multimeters with FPGA-based signal processing and analog front-end powered from separate regulators. IC Role / Device Role / Timing Role: Monitors +2.93V FPGA core rail and +2.19V ADC reference rail; RST2 resets FPGA upon undervoltage; WDI confirms firmware health. Use Value: Guarantees measurement integrity by preventing FPGA configuration errors or ADC reference instability due to supply droop. |
| Computers | Multivoltage Systems |
Use Scenario: Industrial PC motherboard with +3.3V I/O and +2.5V memory interface rails. IC Role / Device Role / Timing Role: Tracks both rails; asserts RST2 referenced to +2.5V rail to synchronize reset with memory controller power domain. Use Value: Eliminates timing skew between CPU and DRAM reset signals-prevents boot failure from partial power sequencing. |
Use Scenario: Programmable logic controller (PLC) backplane with mixed +3.0V, +2.2V, and +1.8V subsystems. IC Role / Device Role / Timing Role: Provides dedicated dual-rail supervision for critical control logic; MR input enables hardware-initiated system-wide reset. Use Value: Enables deterministic fail-safe state recovery without software intervention-meets SIL-2 functional safety requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6359SYUT-T | Same 2.93V/2.19V thresholds and watchdog, but RST output referenced to VCC1 instead of VCC2 | Requires reset load referenced to primary supply rail-not suitable when reset must track secondary rail behavior | Select MAX6359SYUT-T only if system reset logic is tied to VCC1 domain and RST2 referencing is unnecessary |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only); no dual-rail monitoring or VCC2-referenced output | Lacks dual-threshold capability and watchdog-requires additional ICs to replicate MAX6360SYUT-T functionality | Choose TPS3808G33DBVR only for single-rail designs where cost minimization outweighs integration benefits |
Compared with MAX6359SYUT-T, MAX6360SYUT-T provides VCC2-referenced reset essential for secondary-rail-critical systems; versus TPS3808G33DBVR, it delivers integrated dual-monitoring and watchdog-reducing BOM count and PCB area by one component.

FAQ
What is the reset output configuration of the MAX6360SYUT-T?
The MAX6360SYUT-T features a single active-low push-pull reset output (RST2) referenced to VCC2. Unlike open-drain alternatives, this eliminates the need for an external pull-up resistor and ensures rail-to-rail output swing synchronized to the secondary supply domain. This configuration is confirmed in the Pin Description table and Functional Diagram on page 6 of the datasheet.
What are the exact voltage thresholds for MAX6360SYUT-T?
The MAX6360SYUT-T has a VCC1 threshold of 2.93V (±0.05V at +25°C) and a VCC2 threshold of 2.19V (±0.03V at +25°C), as specified in the Voltage Threshold Levels table and Electrical Characteristics section. These values are factory-trimmed and guaranteed over –40°C to +85°C.
Does MAX6360SYUT-T include a watchdog timer, and what are its timeout periods?
Yes, the MAX6360SYUT-T includes a dual-mode watchdog timer with a 46.4s startup timeout period and a 2.9s normal timeout period. The startup mode accommodates lengthy system initialization; the normal mode enforces rapid response to processor hang. These values are explicitly listed in the Electrical Characteristics table under "Watchdog Timeout Period".
What package type and pin count does MAX6360SYUT-T use?
The MAX6360SYUT-T uses a 6-pin SOT23 package (U6-1 outline, land pattern 90-0175), with 2.9mm × 1.6mm footprint and 0.95mm pin pitch. This is confirmed in the Ordering Information table and Pin Configurations section (page 9) of the datasheet.
Is MAX6360SYUT-T compatible with lead-free soldering processes?
Yes, MAX6360SYUT-T is offered in lead(Pb)-free packaging. The "-T" suffix indicates standard packaging; lead-free versions use the "+T" suffix per the Ordering Information note. Both variants comply with RoHS Directive 2011/65/EU and support standard reflow profiles.
