Product details
Overview
MAX6360SVUT+T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with active-low push-pull reset referenced to VCC2, factory-set VCC1 threshold of 2.93V and VCC2 threshold of 1.58V, 20µA supply current, and integrated watchdog timer featuring 46.4s startup and 2.9s normal timeout periods - used in multivoltage embedded systems requiring reliable power-on reset and processor activity monitoring.
For engineers reviewing the MAX6360SVUT+T datasheet, MAX6360SVUT+T pinout, MAX6360SVUT+T application, or MAX6360SVUT+T equivalent, key selection considerations include dual-supply reset assertion logic, VCC2-referenced RST2 output compatibility, watchdog timing modes, guaranteed RESET validity down to VCC1/VCC2 = 1.0V, and SOT23-6 lead-free packaging compliance.
Technical Context
The MAX6360SVUT+T implements independent voltage monitoring on two supplies (VCC1 and VCC2), asserting reset whenever either drops below its precision factory-trimmed threshold (2.93V ±0.05V for VCC1, 1.58V ±0.03V for VCC2). Its reset generator guarantees valid output state as long as at least one supply remains ≥1.0V.
It integrates a dual-mode watchdog timer: a 46.4s startup timeout enables full system initialization after power-up or manual reset, followed by a 2.9s normal timeout that requires periodic WDI transitions to prevent reset - supporting robust μP supervision in battery-powered and industrial controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 2.93V ±0.05V at +25°C; ensures precise detection of +3.0V rail undervoltage before system instability |
| VCC2 Threshold | 1.58V ±0.03V at +25°C; enables reliable monitoring of low-voltage logic rails such as +1.8V or +1.5V domains |
| Supply Current | 20µA typical; supports ultra-low-power operation in portable/battery-powered equipment |
| Reset Timeout | 100–280ms; provides sufficient pulse width to meet μP reset hold-time requirements across temperature |
| Watchdog Startup Timeout | 46.4s; allows extended boot sequences in complex embedded systems before watchdog enforcement begins |
| Watchdog Normal Timeout | 2.9s; delivers rapid fault response to stalled processor execution without excessive delay |
| Operating Temp | -40°C to +85°C; qualified for industrial and automotive-adjacent environments |
Pinout & Package
MAX6360SVUT+T is housed in a RoHS-compliant 6-pin SOT23 package (U6-1 outline) with 0.95mm pitch, footprint-compatible with standard SOT23-6 land pattern 90-0175, and rated for 695mW power dissipation at +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST2 | Active-low push-pull reset output referenced to VCC2; drives low during fault or manual reset, high-impedance when inactive |
| 2 | GND | Ground reference for internal comparators, watchdog, and reset generator |
| 3 | MR | Debounced manual-reset input; pull low to force reset; internally pulled up ~63.5kΩ to VCC1 |
| 4 | VCC2 | Secondary supply input and monitored rail; powers device when > VCC1 and defines RST2 reference |
| 5 | WDI | Watchdog input; rising/falling edge clears timer; sustained high/low >2.9s triggers reset |
| 6 | VCC1 | Primary supply input and monitored rail; powers device when > VCC2 and sets VCC1 threshold trip point |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage thresholds | Factory-trimmed 2.93V (VCC1) and 1.58V (VCC2) enable simultaneous monitoring of +3.0V and +1.8V rails without external components |
| VCC2-referenced RST2 output | Push-pull driver referenced to VCC2 ensures correct logic levels for peripherals powered by same rail |
| Dual-mode watchdog timer | 46.4s startup + 2.9s normal timeout eliminates false resets during boot while enabling fast fault detection in runtime |
| RESET validity to 1.0V | Guaranteed functional reset output even as either VCC1 or VCC2 decays to 1.0V, supporting brownout-safe sequencing |
| Low quiescent current | 20µA typical ICC1+ICC2 minimizes battery drain in always-on supervisory applications |
Applications
| Computers | Controllers |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6359SVUT+T | Same VCC1/VCC2 thresholds (2.93V/1.58V), but RST output referenced to VCC1 instead of VCC2; no RST2 pin | Requires reset signal referenced to primary rail only; unsuitable where peripheral reset must track VCC2 domain | Select MAX6359SVUT+T only if system reset logic is tied to VCC1 and no VCC2-synchronized reset is needed |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only); no dual-rail monitoring or watchdog timer; 1.6µA IQ | Lacks VCC2 monitoring and watchdog functionality; suitable only for single-rail systems without processor supervision needs | Choose TPS3808G33DBVR only for cost-sensitive, single-voltage applications where watchdog and dual-threshold features are unnecessary |
Compared with MAX6359SVUT+T, MAX6360SVUT+T provides VCC2-referenced RST2 critical for peripherals powered by secondary rails; versus TPS3808G33DBVR, it adds essential dual-voltage monitoring and watchdog capability at higher quiescent current - making it the only viable option for multivoltage systems requiring coordinated reset and runtime supervision.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6360SVUT+T?
The MAX6360SVUT+T has a factory-set VCC1 threshold of 2.93V (±0.05V at +25°C) and VCC2 threshold of 1.58V (±0.03V at +25°C), as defined by the "SV" suffix per the Voltage Threshold Levels table. These values are precision-trimmed and guaranteed over -40°C to +85°C, ensuring consistent undervoltage detection across operating conditions for the MAX6360SVUT+T.
How does the watchdog timer on the MAX6360SVUT+T operate during system startup?
The MAX6360SVUT+T watchdog timer initiates a 46.4s startup timeout period after any reset event (power-up, MR assertion, or watchdog timeout), allowing full system initialization before enforcing the 2.9s normal timeout. This dual-mode behavior prevents spurious resets during boot while maintaining rapid fault detection once operational - a key feature distinguishing the MAX6360SVUT+T from single-mode supervisors.
Is the RST2 output of the MAX6360SVUT+T compatible with peripherals powered by VCC2?
Yes, the RST2 output of the MAX6360SVUT+T is an active-low push-pull driver explicitly referenced to VCC2, meaning its high-state voltage tracks VCC2 and its low-state is near GND. This ensures correct logic-level compatibility with peripherals powered from the same VCC2 rail, eliminating level-shifting requirements and making the MAX6360SVUT+T ideal for tightly coupled multivoltage subsystems.
What is the minimum supply voltage required for the MAX6360SVUT+T to maintain valid reset output?
The MAX6360SVUT+T guarantees valid reset output as long as either VCC1 or VCC2 remains ≥1.0V, per Absolute Maximum Ratings and Electrical Characteristics. This "fail-safe" design ensures the MAX6360SVUT+T continues asserting reset during deep brownout conditions, protecting downstream logic even as supplies collapse - a critical capability not found in basic reset ICs.
Does the MAX6360SVUT+T require external components to function in a dual-voltage system?
No, the MAX6360SVUT+T requires no external components for basic dual-voltage supervision: its precision thresholds, debounced MR input, and watchdog timer are fully integrated. Unlike discrete solutions or older supervisors, the MAX6360SVUT+T eliminates external resistors, capacitors, and comparators - reducing BOM cost, PCB area, and calibration effort while improving temperature stability and reliability.
