Product details
Overview
MAX6830VDUT+T from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory IC in 6-pin SOT23 package, monitoring primary VCC (1.53V–2.0V range) and secondary VCC2 (1.575V threshold) 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, and software fault conditions in battery-powered embedded systems.
For engineers reviewing the MAX6830VDUT+T datasheet, MAX6830VDUT+T pinout, MAX6830VDUT+T application, or MAX6830VDUT+T equivalent, this page delivers verified electrical parameters, temperature-stable reset thresholds, watchdog timing behavior, and real-world integration guidance for multivoltage portable and industrial controllers.
Technical Context
The MAX6830VDUT+T implements dual independent voltage monitoring: VCC (factory-set to 1.58V ±0.045V at -40°C to +125°C) and VCC2 (factory-trimmed to 1.575V ±0.054V). Its internal 1.6s watchdog timer clears on WDI edge transitions and asserts reset if no activity occurs beyond timeout - critical for firmware hang detection in safety-critical embedded nodes.
It features a push-pull RESET output that drives high (≥0.8×VCC) when deasserted and low (≤0.3V at ISINK = 100µA) when asserted, with guaranteed valid operation down to VCC = +1.2V across full temperature range. The MR input includes a 50kΩ internal pullup and supports CMOS-level triggering with 1µs minimum pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 1.58V (min 1.521V, max 1.629V at -40°C to +125°C) - sets primary supply brownout detection point for 1.53V–2.0V systems |
| VCC2 Threshold | 1.575V (min 1.521V, max 1.629V at -40°C to +125°C) - factory-trimmed secondary monitor for core voltage supervision |
| Reset Timeout Period | 140ms (min), 320ms (max) at -40°C to +125°C - ensures µP completes power stabilization before release |
| Watchdog Timeout | 1.6s nominal (0.80s–2.60s over -40°C to +125°C) - provides deterministic firmware execution window before forced reset |
| Supply Current (ICC) | 25µA max at VCC = +1.8V, -40°C to +125°C - enables multi-year battery life in always-on portable instrumentation |
| Operating Temp Range | -40°C to +125°C - qualified for under-hood automotive modules and industrial edge controllers |
| RESET Output Type | Push-pull active-high - eliminates external pullup resistor, simplifies interface to µP reset pins requiring high-assertion |
Pinout & Package
Package: 6-pin SOT23 (U6+1 outline, land pattern 90-0175), RoHS-compliant lead-free (+T suffix), 1.6mm × 2.9mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull reset output - drives high during normal operation; pulls low only during reset assertion |
| 2 | GND | Ground reference for all internal comparators and logic - must be low-impedance connection to system ground plane |
| 3 | MR | Manual reset input (active-low) - internally pulled up to VCC via 50kΩ; 1µs pulse sufficient to trigger reset |
| 4 | WDI | Watchdog input - toggling within 1.6s prevents reset; unconnected or three-stated disables watchdog |
| 5 | VCC2 | Secondary supply monitor input - connects directly to 1.575V core rail; no external components required |
| 6 | VCC | Primary supply input - powers device and monitors 1.53V–2.0V I/O rail; valid operation guaranteed down to +1.2V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (1.58V) and VCC2 (1.575V) with separate comparators - enables precise tracking of I/O and core rails in 1.8V/1.5V split-rail systems |
| Guaranteed reset validity to VCC = +1.2V | Ensures RESET output remains functional even during deep brownout - critical for fail-safe shutdown sequencing in battery-depleted states |
| 1.6s watchdog with edge-triggered clear | Resets timer on any WDI rising or falling edge - allows flexible software polling without strict periodicity, reducing firmware overhead |
| No external components required | Factory-trimmed thresholds and integrated pullup eliminate resistors, capacitors, and trimming - reduces BOM count and layout area by ≥3 components |
| Immunity to short negative VCC transients | Withstands ≤20µs, 100mV VCC glitches without false reset - improves robustness in electrically noisy environments like motor control subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6829VDUT+T | Active-low push-pull RESET output; identical VCC/VCC2 thresholds and watchdog timing | Requires inverted reset logic on µP side; incompatible with µPs expecting active-high reset assertion | Select when host µP reset pin is active-low and board layout cannot accommodate level-shifting. |
| MAX6831VDUT+T | Open-drain RESET output; same VCC/VCC2 thresholds, watchdog, and temperature range | Needs external pullup resistor; supports bidirectional reset pins (e.g., Motorola 68HC11) and wired-OR reset buses | Choose for systems with shared reset busses or µPs with bidirectional reset I/O requiring open-drain drive. |
Compared with MAX6830VDUT+T, MAX6829VDUT+T provides identical supervision but inverted reset polarity, while MAX6831VDUT+T trades push-pull drive for open-drain flexibility - selection depends strictly on host µP reset pin logic and bus architecture, not performance.

FAQ
What is the exact VCC reset threshold voltage for MAX6830VDUT+T across temperature?
The MAX6830VDUT+T has a VCC reset threshold of 1.58V typical, with min/max limits of 1.521V and 1.629V over -40°C to +125°C. This is factory-trimmed per the 'V' suffix in MAX6830VDUT+T and applies to the primary supply monitor pin (pin 6). The threshold exhibits ≤60ppm/°C drift, ensuring stability across operating conditions.
Does MAX6830VDUT+T support monitoring a 1.5V core rail and 1.8V I/O rail simultaneously?
Yes. MAX6830VDUT+T monitors VCC (pin 6) at 1.58V and VCC2 (pin 5) at 1.575V - both thresholds fall within the 1.5V–1.8V range. For a true 1.8V I/O rail, use MAX6830SDUT+T (2.63V VCC threshold) or MAX6830TDUT+T (3.08V), while retaining the same 1.575V VCC2 setting for the 1.5V core.
What is the watchdog timeout behavior of MAX6830VDUT+T when WDI is left unconnected?
When WDI (pin 4) is unconnected, MAX6830VDUT+T disables the watchdog function. The internal driver cycles low-high-low every ~1.4s, preventing timeout. No reset is generated due to watchdog expiration. To enable watchdog, drive WDI with clean edges at intervals <1.6s nominal.
Can MAX6830VDUT+T operate with VCC as low as 1.0V?
No. MAX6830VDUT+T is guaranteed functional only down to VCC = +1.2V across -40°C to +125°C. While the broader MAX6826–MAX6831 family guarantees operation to +1.0V for some variants (e.g., L/M/T versions), the 'V' suffix variant (MAX6830VDUT+T) specifies +1.2V minimum per Electrical Characteristics table on page 2.
Is the RESET output of MAX6830VDUT+T compatible with µPs requiring active-low reset signals?
No. MAX6830VDUT+T features an active-high push-pull RESET output (pin 1). For active-low reset compatibility, use MAX6829VDUT+T (same thresholds, active-low push-pull) or MAX6831VDUT+T (active-low open-drain). Direct substitution without logic inversion will cause system malfunction.
