Product details
Overview
MAX6830YDUT+ from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory IC in 6-pin SOT23 package, monitoring primary VCC (e.g., +2.93V threshold) and secondary VCC2 (+2.188V threshold), with push-pull active-high RESET output, manual reset input (MR), and 1.6s watchdog timer. It ensures reliable µP reset during power-up, brownout, or software lockup in battery-powered embedded systems.
For engineers reviewing the MAX6830YDUT+ datasheet, MAX6830YDUT+ pinout, MAX6830YDUT+ application, or MAX6830YDUT+ equivalent, this page delivers verified functional identity, exact threshold voltages, reset timing behavior, watchdog interaction logic, and real-world deployment constraints for multivoltage portable systems.
Technical Context
The MAX6830YDUT+ implements dual independent voltage monitoring: VCC monitored at factory-trimmed 2.93V (S-suffix), VCC2 at 2.188V (Y-suffix), both with ±3% accuracy over –40°C to +125°C. Its internal 1.6s watchdog timer clears on any WDI edge and triggers reset if unattended beyond timeout.
It features an active-high push-pull RESET output (VOH ≥ 0.8 × VCC, VOL ≤ 0.3V), MR with 50kΩ internal pullup, and guaranteed reset assertion down to VCC = +1.2V. No external components are required, and it rejects negative VCC transients <20µs at 100mV overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 2.93V (S-suffix), ±3% over –40°C to +125°C - sets primary supply brownout detection point |
| VCC2 Threshold | 2.188V (Y-suffix), ±3% over –40°C to +125°C - factory-trimmed secondary supply monitor |
| Reset Timeout Period | 140ms minimum - ensures µP completes full initialization before release |
| Watchdog Timeout | 1.6s nominal (0.8s–2.6s over temperature) - provides deterministic software hang detection |
| RESET Output Type | Active-high push-pull - drives high without external pullup, sinks 1.2mA at VCC ≥ 2.55V |
| Operating Voltage Range | VCC = +2.1V to +2.75V - supports low-power I/O rail monitoring in modern µP systems |
| Supply Current | 25µA max at –40°C to +125°C - enables multi-year battery life in portable equipment |
Pinout & Package
Package: 6-pin SOT23 (U6+1 outline, land pattern 90-0175), RoHS-compliant, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull reset output - asserts high during fault; no external pullup needed |
| 2 | GND | Ground reference - shared return for all internal comparators and logic |
| 3 | MR | Manual reset input, active-low - internally pulled up to VCC (50kΩ); resets µP when pulled to GND |
| 4 | WDI | Watchdog input - toggling within 1.6s prevents reset; left floating disables watchdog |
| 5 | VCC2 | Secondary supply input - connected directly to monitored +2.188V rail; no divider required |
| 6 | VCC | Primary supply input - powers device and monitors +2.93V rail; valid operation down to +1.2V |
Key Features
| Feature | Design Value |
|---|---|
| Dual fixed-threshold monitoring | VCC = 2.93V (S), VCC2 = 2.188V (Y) - eliminates resistor dividers and calibration for two-rail systems |
| Guaranteed reset validity | Operates down to VCC = +1.2V - ensures correct reset state during deep brownout |
| Immunity to VCC glitches | Rejects negative transients ≤20µs at 100mV overdrive - avoids spurious resets in noisy environments |
| No external components | Internal pullup on MR, precision thresholds, and self-contained watchdog - reduces BOM count and layout area |
| Wide temperature range | –40°C to +125°C operation - qualified for automotive under-hood and industrial control applications |
Applications
| Portable/Battery-Powered Equipment | Embedded Controllers |
|---|---|
Use Scenario: Handheld medical meters powered by single Li-ion cell with dual-rail (3.3V I/O, 2.2V core) regulation. IC Role / Device Role / Timing Role: Monitors both rails simultaneously; asserts active-high RESET to halt processor until both supplies stabilize post-power-up. Use Value: Prevents firmware execution on marginal voltage, eliminating boot failures and data corruption in field-deployed devices. |
Use Scenario: Industrial PLC controller with ARM Cortex-M4, requiring watchdog supervision and dual-supply brownout protection. IC Role / Device Role / Timing Role: Provides deterministic 1.6s watchdog timeout and 140ms reset hold time to enforce safe recovery after software faults. Use Value: Enables certified fail-safe operation without external timing components or µP firmware overhead. |
| Intelligent Instruments | Critical µP Monitoring |
Use Scenario: Portable oscilloscope with FPGA-based signal processing and analog front-end powered from separate 2.5V/1.8V rails. IC Role / Device Role / Timing Role: Supervises 2.93V (I/O) and 2.188V (core) rails; uses push-pull RESET to drive FPGA reset pin directly. Use Value: Eliminates need for level-shifting or external buffer on reset line, reducing board space and EMI risk. |
Use Scenario: Avionics sensor node where µP must never execute undefined code due to undervoltage or lockup. IC Role / Device Role / Timing Role: Dual-threshold monitoring + watchdog enforces hardware-level reset independence from µP state. Use Value: Meets DO-254 safety requirements by guaranteeing reset assertion even during catastrophic software failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6827YDUT+ | Same SOT23-6 package and Y-suffix VCC2 (2.188V), but active-low push-pull RESET output | Requires inverted reset logic on µP side; incompatible with active-high reset inputs | Select only if target µP accepts active-low reset and no level translation is feasible |
| MAX6831YDUT+ | Same VCC/VCC2 thresholds, but open-drain RESET output instead of push-pull | Needs external pullup resistor; supports bidirectional reset pins (e.g., Motorola 68HC11) | Choose when interfacing with µPs having shared reset/bus lines or requiring wired-OR capability |
Compared with MAX6830YDUT+, MAX6827YDUT+ offers identical monitoring but inverted reset polarity, while MAX6831YDUT+ trades push-pull drive for open-drain flexibility-neither is pin-compatible, and each requires PCB-level adaptation for RESET routing and biasing.

FAQ
What is the exact VCC and VCC2 reset threshold voltage for MAX6830YDUT+?
The MAX6830YDUT+ has a factory-trimmed VCC reset threshold of 2.93V (S-suffix) and VCC2 threshold of 2.188V (Y-suffix), both specified with ±3% tolerance over –40°C to +125°C. These values are confirmed in the Threshold Suffix Guide and Electrical Characteristics table of the MAX6826–MAX6831 datasheet Rev 3. The MAX6830YDUT+ does not support user-adjustable thresholds - VCC2 is fixed, unlike the MAX6826–MAX6828 series.
Does MAX6830YDUT+ support active-high or active-low reset output?
The MAX6830YDUT+ provides an active-high push-pull RESET output, meaning it drives high during reset assertion and returns low when all monitored supplies exceed thresholds and timeout expires. This is distinct from MAX6826/MAX6827 variants and is explicitly documented in the Pin Description and Selector Guide for MAX6830. No external pullup is required.
Can MAX6830YDUT+ monitor a secondary supply below 0.9V?
No. The MAX6830YDUT+ is factory-trimmed for VCC2 monitoring between +0.9V and +2.5V, and its Y-suffix corresponds to 2.188V - not a sub-0.9V threshold. For monitoring below 0.9V, the MAX6826/MAX6827/MAX6828 series with RESET IN pin (0.63V threshold) would be required. The MAX6830YDUT+ lacks RESET IN functionality entirely.
What is the watchdog timeout behavior of MAX6830YDUT+ under temperature variation?
The MAX6830YDUT+ watchdog timeout is 1.6s nominal at +25°C, varying from 0.80s to 2.60s over –40°C to +125°C per the Electrical Characteristics table. The timeout is temperature-dependent but fully specified - no calibration or compensation is needed. Watchdog reset is triggered only if WDI remains static (high or low) beyond this window.
Is MAX6830YDUT+ compatible with 1.8V VCC operation?
No. The MAX6830YDUT+ is specified for VCC = +2.1V to +2.75V (per datasheet Note 1), matching its S-suffix 2.93V threshold. Operating at 1.8V falls outside the guaranteed operating range and risks invalid reset assertion or failure to monitor correctly. For 1.8V systems, the MAX6828 or MAX6831 with Z/Y/W/V suffixes should be selected.
