Product details
Overview
MAX6830VFUT+ from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring primary VCC (1.53V–2.0V range) and secondary VCC2 (1.525V–1.625V at -40°C to +85°C), with push-pull active-high RESET output, manual reset input (MR), and 1.6s watchdog timeout. It ensures reliable µP reset during power-up, brownout, or software hang in battery-powered embedded systems.
For engineers reviewing the MAX6830VFUT+ datasheet, MAX6830VFUT+ pinout, MAX6830VFUT+ application, or MAX6830VFUT+ equivalent, this page delivers verified electrical parameters, exact pin functions, real-world use cases for multivoltage portable systems, and two validated alternative parts with documented functional and application differences.
Technical Context
The MAX6830VFUT+ integrates two independent voltage monitors: one factory-trimmed for VCC (threshold = 1.58V typ, ±0.05V over temp) and another for VCC2 (1.575V typ, ±0.054V over temp), both guaranteed valid down to VCC = +1.2V. Its internal watchdog timer triggers reset if WDI remains static >1.6s (min 0.8s, max 2.6s over temperature), cleared on any WDI edge.
This device uses BiCMOS process (750 transistors), features 50kΩ internal MR pullup, 140ms min reset timeout (100–320ms over temp), and operates across -40°C to +125°C. RESET asserts high when VCC/VCC2 fall below thresholds, MR pulls low, or watchdog times out - maintaining assertion for full timeout after recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | +1.53V to +2.0V - supports core supply monitoring in low-power µP systems like ARM Cortex-M0+ or RISC-V SoCs. |
| VCC2 Threshold | 1.575V (typ), ±0.054V over -40°C to +125°C - factory-trimmed for precise secondary rail supervision without external resistors. |
| RESET Output Type | Push-pull active-high - drives high-impedance µP reset pins directly; VOH = 0.8×VCC at ISOURCE = 200µA. |
| Reset Timeout | 140ms (min), 200ms (typ), 320ms (max) - ensures stable power re-establishment before µP release. |
| Watchdog Timeout | 1.6s (nominal), 0.8s–2.6s over temperature - detects firmware lockups in deeply embedded applications. |
| Supply Current | 25µA max at VCC = +2.0V, -40°C to +125°C - enables multi-year battery life in portable instrumentation. |
| Operating Temp | -40°C to +125°C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
Package: 6-pin SOT23 (U6+1 outline, land pattern 90-0175), RoHS-compliant, lead-free (+T suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull reset output - asserts high during fault; sinks 1.2mA at VCC ≥ 2.55V, VOL ≤ 0.3V. |
| 2 | GND | Ground reference - shared return for all internal comparators and logic. |
| 3 | MR | Manual reset input (active-low) - internal 50kΩ pullup to VCC; 1µs minimum pulse width required. |
| 4 | WDI | Watchdog input - toggling within 1.6s prevents reset; unconnected disables watchdog. |
| 5 | VCC2 | Secondary supply monitor input - connects directly to 0.9V–2.5V rail; threshold factory-set to 1.575V. |
| 6 | VCC | Primary supply input - powers device and sets VCC monitor threshold (1.58V typ); valid down to +1.2V. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (1.53V–2.0V) and VCC2 (1.525V–1.625V) with separate thresholds - eliminates need for discrete supervisors in dual-rail SoC designs. |
| Factory-trimmed VCC2 threshold | 1.575V ±0.054V over full temperature range - removes resistor-divider calibration burden and improves accuracy vs. adjustable solutions. |
| Guaranteed reset validity to VCC = +1.2V | RESET output remains functional even as primary supply drops to 1.2V - ensures fail-safe behavior during deep brownout conditions. |
| No external components required | Integrates pullup on MR, precision references, watchdog timer, and reset delay generator - reduces BOM count and PCB area in space-constrained modules. |
| Immunity to short VCC transients | Withstands negative-going VCC glitches ≤20µs at 100mV overdrive - prevents spurious resets in electrically noisy portable equipment. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6829VFUT+ | Active-low push-pull RESET output; identical VCC/VCC2 thresholds and watchdog specs. | Requires inverted reset logic on µP side; incompatible with µPs expecting active-high reset assertion. | Select when host µP has active-low reset input and board layout cannot accommodate level-shifting. |
| MAX6831VFUT+ | Open-drain RESET output; same VCC/VCC2 thresholds and watchdog timing. | Needs external pullup resistor; supports bidirectional reset pins (e.g., Motorola 68HC11) and wired-OR configurations. | Choose for systems requiring reset line sharing among multiple supervisors or interfacing with legacy µPs with bidirectional reset I/O. |
Compared with MAX6830VFUT+, MAX6829VFUT+ provides identical supervision but inverted reset polarity, while MAX6831VFUT+ trades push-pull drive for open-drain flexibility - both retain the same 1.58V/1.575V thresholds and 1.6s watchdog, enabling direct substitution only where reset interface matches.

FAQ
What is the exact VCC2 reset threshold voltage for MAX6830VFUT+?
The MAX6830VFUT+ has a factory-trimmed VCC2 reset threshold of 1.575V (typical), with guaranteed range of 1.521V to 1.629V over -40°C to +125°C operation. This value is fixed per the 'V' suffix in the part number and does not require external resistor configuration - it is specified in the Electrical Characteristics table under VTH2 for suffix V.
Does MAX6830VFUT+ support active-high or active-low reset output?
The MAX6830VFUT+ provides an active-high push-pull RESET output. When a fault occurs (VCC or VCC2 drop below threshold, MR pulled low, or watchdog timeout), RESET asserts high. It returns low after the reset timeout period ends. This is confirmed in the Pin Description table and Selector Guide, which lists MAX6830 as having "ACTIVE-HIGH RESET".
Can MAX6830VFUT+ monitor a 1.2V supply rail?
No - the MAX6830VFUT+ is specifically configured for VCC monitoring in the +1.53V to +2.0V range and VCC2 monitoring at 1.575V (typ). For 1.2V rail supervision, the MAX6826/MAX6827/MAX6828 series with user-adjustable RESET IN input (0.63V threshold) would be appropriate, or the MAX6830ZFUT+ (VCC2 = 2.313V) is unsuitable. The 'V' suffix defines the threshold; no variant supports 1.2V VCC2.
What is the watchdog timeout tolerance over temperature for MAX6830VFUT+?
The watchdog timeout for MAX6830VFUT+ is 1.6s nominal, with a guaranteed range of 0.80s to 2.60s over the full -40°C to +125°C operating temperature range. This variation is explicitly listed in the Electrical Characteristics table under "Watchdog Timeout Period (tWD)" with conditions TA = -40°C to +125°C.
Is MAX6830VFUT+ pin-compatible with MAX6827 or MAX6828?
No - while all MAX6826–MAX6831 devices share the same 6-pin SOT23 package and pinout, MAX6830VFUT+ differs functionally: it uses VCC2 (pin 5) for factory-trimmed secondary monitoring, whereas MAX6827 uses pin 5 as RESET IN for user-adjustable threshold. Thus, direct PCB substitution requires verification that the connected circuit matches the intended pin function - MAX6830VFUT+ cannot replace MAX6827 without redesigning the VCC2/RESET IN network.
