Product details
Overview
MAX6830VFUT+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) and secondary VCC2 (1.575V nominal) with push-pull active-high RESET output, manual reset input (MR), and 1.6s watchdog timeout. It guarantees valid reset operation down to VCC = +1.2V and supports critical µP monitoring in battery-powered embedded systems.
For engineers reviewing the MAX6830VFUT+T datasheet, MAX6830VFUT+T pinout, MAX6830VFUT+T application, or MAX6830VFUT+T equivalent, this page delivers verified functional identity, exact threshold values (VTH = 1.575V, VTH2 = 1.575V), reset timing (140ms min timeout), watchdog behavior, and validated alternative options - all confirmed for the precise MAX6830VFUT+T variant.
Technical Context
The MAX6830VFUT+T implements dual independent voltage monitoring: VCC (primary supply) is compared against a factory-trimmed 1.575V threshold (suffix 'V'), while VCC2 (pin 5) monitors a second supply at the same 1.575V threshold. Its push-pull RESET output asserts high during fault conditions and remains asserted for ≥140ms after recovery.
It integrates a 1.6s watchdog timer cleared by WDI edge transitions, a manual-reset input (MR) with internal 50kΩ pullup, and operates across –40°C to +125°C with guaranteed reset validity down to VCC = +1.2V. No external components are required for basic supervision functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 1.575V (factory-trimmed, ±25mV over –40°C to +125°C); sets primary power-fail detection point for 1.53V–2.0V supply range |
| VCC2 Threshold | 1.575V (factory-trimmed, ±25mV over –40°C to +125°C); enables simultaneous monitoring of dual-core or I/O/core rail pair |
| Reset Timeout Period | 140ms minimum; ensures µP completes full power stabilization before release from reset state |
| Watchdog Timeout | 1.6s nominal (0.8s–2.6s over temperature); provides fail-safe software execution monitoring with edge-triggered clearing |
| RESET Output Type | Push-pull active-high; drives high during fault and releases to high-impedance-like state post-timeout without external pullup |
| Operating Voltage Range | VCC = +1.53V to +2.0V; supports modern low-voltage SoCs and ultra-low-power MCUs |
| Supply Current | 25µA max at –40°C to +125°C (VCC = +1.8V); enables multi-year battery life in portable applications |
Pinout & Package
Package: 6-pin SOT23 (U6+1 outline, land pattern 90-0175), RoHS-compliant, lead-free (indicated by '+T' suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull reset output; asserts high during VCC/VCC2 undervoltage, MR assertion, or watchdog timeout |
| 2 | GND | Ground reference for all internal comparators, timers, and output drivers |
| 3 | MR | Active-low manual reset input with internal 50kΩ pullup to VCC; debounced internally, no external RC needed |
| 4 | WDI | Watchdog input; edge-sensitive (rising/falling); clears 1.6s timer on transition; disabled if left floating or three-stated |
| 5 | VCC2 | Dedicated secondary supply monitor input; factory-trimmed to 1.575V threshold; not user-adjustable |
| 6 | VCC | Primary supply input and power source; powers internal circuitry and sets operating voltage range (1.53V–2.0V) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of primary (VCC) and secondary (VCC2) rails with separate, factory-trimmed thresholds |
| Guaranteed reset validity down to VCC = +1.2V | Ensures deterministic reset assertion even during deep brownout, critical for reliable low-voltage MCU startup |
| No external components required | Eliminates BOM cost and board space for RC networks, pullups, or discrete supervisors in standard configurations |
| Immunity to short negative VCC transients | Withstands ≤20µs, 100mV VCC glitches without spurious reset-reduces false triggers in noisy environments |
| 1.6s watchdog with edge-triggered clear | Enables robust software health checking without requiring precise pulse timing or duty-cycle management |
Applications
| Portable/Battery-Powered Equipment | Embedded Controllers |
|---|---|
Use Scenario: Wearable health monitor powered by single Li-ion cell with dual-rail PMIC (1.8V core, 1.5V sensor interface). IC Role / Device Role / Timing Role: MAX6830VFUT+T monitors both rails and asserts active-high RESET to halt MCU until both supplies stabilize post-power-up. Use Value: Prevents erratic firmware execution during partial power ramp; 140ms timeout ensures complete LDO settling before boot. |
Use Scenario: Industrial PLC controller with ARM Cortex-M7 MCU requiring guaranteed reset during 12V-to-1.5V DC/DC transient events. IC Role / Device Role / Timing Role: MAX6830VFUT+T acts as primary supervisor, asserting RESET on VCC (1.53V–2.0V domain) and VCC2 (1.575V I/O rail) faults. Use Value: Eliminates need for discrete reset generators; push-pull output interfaces directly with MCU's active-high reset pin without pullup resistor. |
| Intelligent Instruments | Critical µP Monitoring |
Use Scenario: Handheld multimeter with dual-supply ADC (1.8V analog, 1.5V digital) and real-time clock backup. IC Role / Device Role / Timing Role: MAX6830VFUT+T supervises both domains and feeds watchdog input from ADC conversion interrupt line. Use Value: Detects firmware lockup via missing ADC interrupts; 1.6s timeout balances responsiveness and noise immunity. |
Use Scenario: Medical infusion pump MCU where uncontrolled reset could cause dosing error. IC Role / Device Role / Timing Role: MAX6830VFUT+T provides fail-safe reset initiation and hold-off using MR for controlled service-mode resets. Use Value: Internal 50kΩ MR pullup prevents floating-input failures; MR assertion extends reset beyond timeout for safe state capture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6827VFUT+T | Same VCC/VCC2 thresholds (1.575V), but features active-low push-pull RESET output instead of active-high | Requires inverted reset logic or level-shifting when interfacing with µPs expecting active-low reset assertion | Select MAX6827VFUT+T only if system design mandates active-low reset polarity and board layout accommodates signal inversion |
| MAX6831VFUT+T | Identical VCC/VCC2 thresholds and watchdog, but uses open-drain RESET output instead of push-pull | Necessitates external pullup resistor and supports bidirectional reset pins (e.g., Motorola 68HC11), unlike push-pull topology | Choose MAX6831VFUT+T when interfacing with µPs having shared reset buses or requiring wired-OR reset arbitration |
Compared with MAX6827VFUT+T and MAX6831VFUT+T, the MAX6830VFUT+T uniquely delivers active-high push-pull RESET without external components-optimizing simplicity and compatibility with modern low-voltage MCUs specifying active-high reset inputs.

FAQ
What is the exact VCC reset threshold voltage for MAX6830VFUT+T?
The MAX6830VFUT+T has a factory-trimmed VCC reset threshold of 1.575V, with tolerance of ±25mV over the full –40°C to +125°C operating temperature range. This value is fixed by the 'V' suffix and applies specifically to the MAX6830VFUT+T variant-not adjustable and not shared with other suffixes like 'W' or 'Z'.
Does MAX6830VFUT+T support monitoring a secondary voltage lower than 1.575V?
No. The MAX6830VFUT+T monitors VCC2 at a fixed 1.575V threshold (same as its VCC threshold). It does not support user-adjustable secondary monitoring like the MAX6826/MAX6827/MAX6828 series, which use the RESET IN pin for sub-0.63V threshold configuration. VCC2 on MAX6830VFUT+T is strictly factory-trimmed and non-adjustable.
What is the function of the WDI pin on MAX6830VFUT+T?
The WDI (Watchdog Input) pin on MAX6830VFUT+T is edge-sensitive: any rising or falling transition clears the internal 1.6s watchdog timer. If WDI remains static (high or low) beyond the timeout period, MAX6830VFUT+T asserts RESET. Leaving WDI unconnected disables the watchdog, as the internal driver toggles it every ~1.4s.
Can MAX6830VFUT+T operate with VCC below 1.53V?
No. The MAX6830VFUT+T is specified for VCC = +1.53V to +2.0V only. While it guarantees valid reset assertion down to VCC = +1.2V, operation below 1.53V violates the absolute minimum supply rating and may result in undefined comparator behavior, incorrect threshold tracking, or failure to power internal circuitry reliably.
Is the RESET output of MAX6830VFUT+T compatible with µPs requiring active-low reset?
No-the MAX6830VFUT+T features an active-high push-pull RESET output. For µPs requiring active-low reset, use MAX6827VFUT+T (active-low push-pull) or MAX6831VFUT+T (open-drain, compatible with external pullup to generate active-low). Direct connection of MAX6830VFUT+T RESET to an active-low µP reset pin will prevent proper system initialization.
