Product details
Overview
The MAX6360SVUT from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with active-low push-pull reset output referenced to VCC2, 2.93V VCC1 threshold, 1.58V VCC2 threshold, 20µA supply current, and integrated watchdog timer (46.4s startup / 2.9s normal timeout). It ensures reliable power-on reset and fault detection in multivoltage embedded systems.
For engineers reviewing the MAX6360SVUT datasheet, MAX6360SVUT pinout, MAX6360SVUT application, or MAX6360SVUT equivalent, key selection criteria include dual-supply monitoring thresholds, VCC2-referenced reset output, watchdog timing behavior, and SOT23-6 package compatibility with space-constrained industrial control and portable designs.
Technical Context
The MAX6360SVUT implements independent precision voltage comparators for VCC1 and VCC2, asserting reset whenever either supply drops below its factory-set threshold (2.93V and 1.58V respectively). Its reset output remains valid as long as either VCC1 or VCC2 exceeds +1.0V, enabling operation during brownout conditions.
It integrates a dual-mode watchdog timer with a 46.4s startup timeout for system initialization and a 2.9s normal timeout for runtime supervision. The WDI input accepts TTL/CMOS-compatible transitions, and the debounced manual-reset input forces reset on low assertion.
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 |
| VCC2 Threshold | 1.58V ±0.03V at +25°C; enables monitoring of low-voltage logic rails like +1.8V or +1.5V |
| Supply Current | 20µA typical; supports ultra-low-power battery-backed applications |
| Reset Timeout | 100ms minimum pulse width; meets μP reset hold-time requirements across temperature |
| Watchdog Startup Timeout | 46.4s; allows full system boot before watchdog enforcement begins |
| Watchdog Normal Timeout | 2.9s; provides rapid fault response during active processor operation |
| Operating Temperature | -40°C to +85°C; qualified for industrial and extended-environment deployment |
Pinout & Package
The MAX6360SVUT is housed in a 6-pin SOT23 package (U6-1 outline), with 1.27mm pitch, 2.9mm × 1.6mm footprint, and thermal pad omitted. Pin 1 is RST2 (active-low push-pull reset referenced to VCC2), Pin 2 is GND, Pin 3 is MR (debounced manual-reset input), Pin 4 is VCC2, Pin 5 is WDI (watchdog input), and Pin 6 is VCC1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST2) | Active-low push-pull reset output | Referenced to VCC2; drives low during fault without external pull-up |
| 2 (GND) | Ground reference | Common return path for all internal comparators and logic |
| 3 (MR) | Debounced manual-reset input | Asserted low forces reset; internally debounced to reject noise |
| 4 (VCC2) | Secondary supply input | Powers device when above VCC1; monitored at 1.58V threshold |
| 5 (WDI) | Watchdog timer input | Edge-triggered; resets watchdog on rising/falling transition |
| 6 (VCC1) | Primary supply input | Powers device when above VCC2; monitored at 2.93V threshold |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously tracks two supplies with separate thresholds (2.93V/1.58V), eliminating need for discrete comparators |
| VCC2-referenced push-pull reset | RST2 output swings rail-to-rail relative to VCC2, ensuring clean interface with low-voltage logic |
| Dual-mode watchdog timer | 46.4s startup timeout accommodates complex boot sequences; 2.9s normal timeout enables fast fault recovery |
| Guaranteed reset validity down to 1.0V | Reset remains asserted and functional even if one supply collapses to 1.0V, supporting brownout resilience |
| 20µA quiescent current | Enables integration into always-on subsystems without compromising battery life |
Applications
| Industrial PLC Controllers | Portable Medical Monitors |
|---|---|
Use Scenario: Monitoring +3.3V I/O supply and +1.5V core logic rail in programmable logic controller modules. IC Role / Device Role / Timing Role: Dual-voltage supervisor providing synchronized reset assertion and watchdog supervision during firmware updates and field operation. Use Value: Prevents erratic controller behavior during partial power loss by asserting reset when either rail falls below 2.93V or 1.58V, while 2.9s watchdog enforces software liveliness. | Use Scenario: Power sequencing and fault detection in handheld ECG devices powered by single-cell Li-ion batteries. IC Role / Device Role / Timing Role: Supervises main DC-DC output (+2.9V) and LDO-regulated sensor rail (+1.5V), with reset tied to microcontroller's active-low reset pin. Use Value: 20µA supply current extends battery runtime; 46.4s startup timeout allows complete analog front-end calibration before watchdog activation. |

IC Role / Device Role / Timing Role: Low-quiescent-current supervisor delivering deterministic reset and watchdog coverage for sleep/wake cycles. Use Value: 2.93V/1.58V thresholds match common regulator outputs; 2.9s watchdog timeout aligns with typical sensor data transmission intervals. |
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 | Push-pull reset referenced to VCC1 (not VCC2); identical thresholds and watchdog specs | Requires reset signal referenced to higher-voltage rail; unsuitable where reset must track low-voltage domain | Select MAX6359SVUT only if reset must be VCC1-synchronous and interface targets +3.0V logic |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only); no VCC2 monitoring or dual-mode watchdog | Lacks dual-rail monitoring capability; requires additional IC for second supply supervision | Choose TPS3808G33DBVR only for single-rail systems where cost and BOM count outweigh dual-monitoring needs |
Compared with MAX6359SVUT, the MAX6360SVUT provides VCC2-referenced reset essential for low-voltage logic domains; compared with TPS3808G33DBVR, it delivers integrated dual-supply monitoring and watchdog functionality in a single chip, reducing component count and layout complexity.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6360SVUT?
The MAX6360SVUT has a factory-set VCC1 threshold of 2.93V (±0.05V at +25°C) and a 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.
Does the MAX6360SVUT provide a push-pull or open-drain reset output?
The MAX6360SVUT provides an active-low push-pull reset output (RST2) referenced to VCC2 - not open-drain. This eliminates the need for an external pull-up resistor and ensures full rail-to-rail drive strength compatible with low-voltage logic interfaces.
How does the watchdog timer on the MAX6360SVUT operate during system startup?
The MAX6360SVUT watchdog timer initiates a 46.4s startup timeout period after any reset event (power-up, MR assertion, or watchdog timeout). During this interval, no WDI transitions are required. Once the startup period ends - or upon the first WDI edge - the timer switches to 2.9s normal timeout mode.
Can the MAX6360SVUT remain functional if one supply rail drops below 1.0V?
No - the MAX6360SVUT guarantees valid reset output only while at least one supply (VCC1 or VCC2) remains ≥1.0V. If both fall below 1.0V, internal circuitry loses bias, and reset behavior is undefined. This 1.0V minimum ensures operation during brownout but not full rail collapse.
What package type and pin count does the MAX6360SVUT use?
The MAX6360SVUT uses a 6-pin SOT23 package (U6-1 outline), with standard 1.27mm lead pitch and 2.9mm × 1.6mm body dimensions. Pin 1 is RST2, Pin 2 is GND, Pin 3 is MR, Pin 4 is VCC2, Pin 5 is WDI, and Pin 6 is VCC1 - matching the MAX6358/MAX6359/MAX6360 pin configuration.
