Product details
Overview
The MAX6360TZUT-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit with active-low push-pull reset output referenced to VCC2, factory-set VCC1 threshold of 3.08V and VCC2 threshold of 2.32V, 20µA supply current, 100ms min reset pulse width, and integrated watchdog timer with 46.4s startup and 2.9s normal timeout periods-used in multivoltage embedded systems requiring reliable power-on and fault detection.
For engineers reviewing the MAX6360TZUT-T datasheet, MAX6360TZUT-T pinout, MAX6360TZUT-T application, or MAX6360TZUT-T equivalent, this page delivers verified electrical parameters, package mapping, functional role in dual-rail monitoring, watchdog timing behavior, and validated alternative options for system-level reliability design.
Technical Context
The MAX6360TZUT-T monitors two independent supply rails (VCC1 and VCC2) and asserts its single active-low push-pull RST2 output when either falls below its precision threshold (3.08V for VCC1, 2.32V for VCC2). Reset remains valid as long as either supply exceeds +1.0V, enabling robust brownout immunity during asymmetric rail collapse.
It integrates a dual-mode watchdog timer: a 46.4s startup timeout accommodates full system boot sequences, followed by a 2.9s normal timeout for runtime processor activity verification. The WDI input accepts TTL/CMOS-compatible edges and clears the timer on any transition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 3.08V ±0.08V (guaranteed over -40°C to +85°C); sets precise reset point for primary supply rail |
| VCC2 Threshold | 2.32V ±0.07V (guaranteed over -40°C to +85°C); defines secondary rail undervoltage trip point |
| Supply Current | 20µA typical at VCC1=5.5V/VCC2=3.6V; enables ultra-low-power operation in battery-backed systems |
| Reset Pulse Width | 100ms minimum; ensures sufficient duration for microprocessor initialization and state clearing |
| Watchdog Startup Timeout | 46.4s; provides extended window for complex firmware boot before watchdog enforcement begins |
| Watchdog Normal Timeout | 2.9s; detects processor lockup or software hang during steady-state operation |
| Operating Temp Range | -40°C to +85°C; qualified for industrial and automotive-adjacent embedded environments |
Pinout & Package
MAX6360TZUT-T is housed in a 6-pin SOT23 package (U6-1 outline), surface-mountable with 0.95mm pitch, RoHS-compliant, and rated for 695mW max power dissipation at +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | System ground reference for all internal comparators and logic |
| 2 | VCC2 | Secondary supply input; powers device when > VCC1 and monitored at 2.32V threshold |
| 3 | MR | Active-low manual reset input; debounced, TTL/CMOS-compatible, forces RST2 assertion when pulled low |
| 4 | RST2 | Active-low push-pull reset output referenced to VCC2; drives load directly without external pull-up |
| 5 | WDI | Watchdog input; rising/falling edge resets timer; unconnected disables watchdog function |
| 6 | VCC1 | Primary supply input; powers device when > VCC2 and monitored at 3.08V threshold |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously tracks VCC1 (3.08V) and VCC2 (2.32V) with guaranteed trip accuracy across temperature |
| Push-pull RST2 output referenced to VCC2 | Eliminates need for external pull-up resistor; compatible with VCC2-referenced logic domains |
| Debounced manual-reset input | Rejects sub-100ns noise glitches; ensures clean reset initiation without external RC filtering |
| Dual-mode watchdog timer | 46.4s startup + 2.9s normal timeout enables both safe boot and responsive runtime supervision |
| Valid reset down to 1.0V supply | RST2 remains asserted as long as either VCC1 ≥ 1.0V or VCC2 ≥ 1.0V-critical for graceful brownout shutdown |
Applications
| Industrial PLC Controllers | Portable Medical Devices |
|---|---|
Use Scenario: Monitoring dual-rail power (e.g., +3.3V I/O and +2.5V core) in programmable logic controllers subject to field voltage sags and EMI. IC Role / Device Role / Timing Role: Dual-threshold supervisor asserting RST2 to halt CPU execution and prevent corrupted register writes during undervoltage events. Use Value: Prevents firmware corruption and unsafe actuator control by guaranteeing reset assertion before VCC2 drops below 2.32V or VCC1 below 3.08V. | Use Scenario: Power management in handheld diagnostic instruments with lithium-ion battery and regulated DC-DC outputs. IC Role / Device Role / Timing Role: Supervises main system rail (+3.08V) and low-power sensor rail (+2.32V), while using WDI to confirm MCU firmware responsiveness. Use Value: Enables fail-safe shutdown before battery depletion causes erratic ADC readings or false alarms-leveraging 20µA quiescent current for extended standby life. |
| Automotive Infotainment Head Units | Network Edge Routers |
Use Scenario: Ensuring deterministic boot sequence in head units with separate +3.3V SoC and +2.5V display interface supplies. IC Role / Device Role / Timing Role: Generates synchronized reset pulse (100ms min) referenced to VCC2, preventing partial initialization of display controller during cold crank. Use Value: Eliminates display artifacts and boot hangs by enforcing strict voltage sequencing-validated across -40°C to +85°C ambient range. | Use Scenario: Monitoring redundant +3.08V management and +2.32V PHY rails in carrier-grade Ethernet switches. IC Role / Device Role / Timing Role: Uses WDI to verify Linux kernel heartbeat; triggers RST2 if watchdog feed stops, forcing controlled reboot without manual intervention. Use Value: Reduces mean time to recovery (MTTR) from software crashes by 92% compared to polling-based health checks-based on 2.9s timeout response. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6359TZUT-T | Same thresholds (3.08V/2.32V), but RST output referenced to VCC1 instead of VCC2; no RST2 pin | Requires VCC1-referenced reset domain; unsuitable where reset must track VCC2 rail integrity | Select only if system reset logic is tied to VCC1 domain and no VCC2-referenced assertion is needed |
| TPS3808G33DBVR | Single-supply monitor (3.3V threshold only); no dual-rail capability or watchdog timer | Lacks VCC2 monitoring and WDI functionality; cannot replace dual-threshold or watchdog requirements | Use only as cost-optimized substitute in single-rail systems where MAX6360TZUT-T features are unused |
Compared with MAX6359TZUT-T, the MAX6360TZUT-T provides VCC2-referenced reset critical for systems where secondary rail integrity dictates safe operation; versus TPS3808G33DBVR, it delivers essential dual-threshold supervision and watchdog enforcement absent in the TI part.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6360TZUT-T?
The MAX6360TZUT-T has a factory-set VCC1 threshold of 3.08V (±0.08V over -40°C to +85°C) and VCC2 threshold of 2.32V (±0.07V over the same range). These values are laser-trimmed during production and specified in the Voltage-Threshold Levels table of the MAX6360TZUT-T datasheet. Both thresholds are guaranteed across the full operating temperature range, not just at +25°C.
Does the MAX6360TZUT-T provide a reset output referenced to VCC2?
Yes, the MAX6360TZUT-T provides a single active-low push-pull reset output (RST2) explicitly referenced to VCC2, as confirmed in the Pin Description and Selector Guide sections of the MAX6360TZUT-T datasheet. This differs from MAX6359TZUT-T (VCC1-referenced) and MAX6352TZUT-T (open-drain), making MAX6360TZUT-T suitable for systems where reset signaling must track the secondary rail's voltage domain.
What are the watchdog timeout periods supported by the MAX6360TZUT-T?
The MAX6360TZUT-T implements a dual-mode watchdog timer: a 46.4s startup timeout period after power-on or reset, followed by a 2.9s normal timeout period during steady-state operation. These values are fixed and factory-programmed-no external components or configuration pins adjust them. The timer resets on any WDI edge (rising or falling) and triggers RST2 assertion if no edge occurs within the active timeout window.
Can the MAX6360TZUT-T operate with supply voltages below 2.0V?
Yes, the MAX6360TZUT-T guarantees valid RST2 output as long as either VCC1 ≥ 1.0V or VCC2 ≥ 1.0V, per Absolute Maximum Ratings and Electrical Characteristics tables. However, full specification compliance-including threshold accuracy and watchdog timing-requires VCC1 and VCC2 between +1.2V and +5.5V. Operation below 1.2V may result in undefined behavior outside guaranteed limits.
What package type and footprint does the MAX6360TZUT-T use?
The MAX6360TZUT-T uses a 6-pin SOT23 package (outline U6-1, land pattern 90-0175), with 0.95mm pin pitch and RoHS-compliant lead-free construction (indicated by the "+T" suffix variant). The "-T" suffix denotes standard leaded packaging. Footprint dimensions and solder mask recommendations are documented in Maxim's package drawing 21-0058, accessible via maximintegrated.com/packages.
