Product details
Overview
MAX6830YGUT+ from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, designed to monitor primary supply (VCC) at +2.12V to +2.25V and secondary supply (VCC2) at +2.19V (typ), 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 portable battery-powered systems.
For engineers reviewing the MAX6830YGUT+ datasheet, MAX6830YGUT+ pinout, MAX6830YGUT+ application, or MAX6830YGUT+ equivalent, key selection criteria include its factory-trimmed dual-threshold monitoring (VCC = 2.19V, VCC2 = 2.188V), guaranteed reset validity down to VCC = +1.2V, 140ms minimum reset timeout, and immunity to short negative VCC transients - all critical for low-voltage embedded controller supervision.
Technical Context
The MAX6830YGUT+ integrates two independent voltage comparators: one for primary VCC (threshold = 2.19V, ±0.06V over -40°C to +125°C) and one factory-trimmed for VCC2 (2.188V, ±0.075V). Its internal 1.6s watchdog timer clears on any WDI edge and triggers reset if no transition occurs within timeout.
It features an active-high push-pull RESET output (VOH ≥ 0.8×VCC, VOL ≤ 0.3V at ISINK = 100µA), MR with 50kΩ internal pullup, and operates across -40°C to +125°C with supply current as low as 7µA (VCC = +3.6V, TA = -40°C to +85°C). Reset assertion is maintained for ≥140ms after all monitored voltages recover.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 2.19V (typ), ±0.06V over -40°C to +125°C - sets primary supply brownout detection point |
| VCC2 Threshold | 2.188V (typ), ±0.075V over -40°C to +125°C - factory-trimmed secondary supply monitor for core/I/O rails |
| Reset Timeout Period | 140ms (min), up to 320ms over temperature - ensures µP completes power stabilization before release |
| Watchdog Timeout | 1.6s (nominal), 0.8s–2.6s over -40°C to +125°C - provides software execution monitoring with wide thermal margin |
| RESET Output Type | Active-high push-pull - drives high without external pullup, compatible with µP reset inputs requiring active-high assertion |
| Supply Current (ICC) | 7µA (typ) at VCC = +3.6V, -40°C to +85°C - enables multi-year battery life in portable equipment |
| Operating Voltage Range | +1.2V to +5.5V (VCC), valid reset asserted down to VCC = +1.2V - supports ultra-low-voltage operation |
Pinout & Package
MAX6830YGUT+ uses a 6-pin SOT23 package (U6+1 outline, land pattern 90-0175), RoHS-compliant, with 1.0mm pitch and 2.9mm × 1.6mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull reset output - asserts high during fault conditions; sinks 100µA while asserted |
| 2 | GND | Ground reference for all internal comparators and logic - must be low-impedance connection |
| 3 | MR | Manual-reset input, active-low, with 50kΩ internal pullup to VCC - momentary GND connection forces system reset |
| 4 | WDI | Watchdog input - rising/falling edge resets 1.6s timer; left unconnected disables watchdog |
| 5 | VCC2 | Secondary supply input - connects directly to monitored I/O or core rail (e.g., 2.2V domain) |
| 6 | VCC | Primary supply input - powers device and sets VCC threshold (2.19V for Y suffix) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises primary (VCC = 2.19V) and secondary (VCC2 = 2.188V) supplies without external components |
| Factory-trimmed VCC2 threshold | Eliminates resistor-divider design effort for secondary rail monitoring down to +0.9V |
| Guaranteed reset validity to VCC = +1.2V | Ensures deterministic reset behavior even during deep brownout, critical for fail-safe embedded systems |
| 1.6s watchdog with edge-triggered clear | Prevents software lockup by requiring periodic WDI transitions - immune to stuck-at logic states |
| No external timing components | Integrates reset timeout delay, watchdog timer, and comparator hysteresis - reduces BOM count and PCB area |
Applications
| Portable/Battery-Powered Equipment | Embedded Controllers |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6829YGUT+ | Active-low push-pull RESET output; identical VCC/VCC2 thresholds and watchdog timing | Requires µP with active-low reset input; incompatible with active-high-only reset pins | Select when interfacing with legacy µPs requiring active-low assertion and same dual-supply monitoring. |
| MAX6831YGUT+ | Open-drain RESET output; otherwise identical VCC/VCC2 thresholds, watchdog, and MR functionality | Needs external pullup resistor; supports bidirectional µP reset pins (e.g., Motorola 68HC11) | Choose for designs requiring wired-OR reset buses or compatibility with bidirectional reset I/O architectures. |
Compared with MAX6830YGUT+, MAX6829YGUT+ offers active-low reset for conventional µP interfaces, while MAX6831YGUT+ provides open-drain flexibility for shared reset lines - all three share identical dual-threshold accuracy, watchdog behavior, and low-voltage operation, enabling drop-in selection based solely on reset polarity and drive architecture needs.

FAQ
What is the exact VCC reset threshold voltage for MAX6830YGUT+?
The MAX6830YGUT+ has a factory-trimmed VCC reset threshold of 2.19V (typical), with a guaranteed range of 2.113V to 2.263V over the full operating temperature range (-40°C to +125°C). This value corresponds to the 'Y' suffix in the part number and is specified in the Electrical Characteristics table under VTH for MAX68__Y variants.
Does MAX6830YGUT+ support monitoring a secondary supply, and what is its threshold?
Yes, MAX6830YGUT+ supports secondary supply monitoring via the VCC2 pin with a factory-trimmed threshold of 2.188V (typical), ranging from 2.113V to 2.263V over -40°C to +125°C. This matches the primary VCC threshold and is explicitly documented for MAX6830 in the VTH2 table under the 'Y' suffix row.
What type of RESET output does MAX6830YGUT+ provide, and how is it driven?
MAX6830YGUT+ provides an active-high push-pull RESET output. When asserted (during fault), it drives high with VOH ≥ 0.8×VCC (tested at ISOURCE = 100µA); when deasserted, it pulls low to ≤0.3V (at ISINK = 100µA). No external pullup is required, simplifying interface to µPs with active-high reset inputs.
How long is the reset timeout period for MAX6830YGUT+, and is it temperature-stable?
The MAX6830YGUT+ guarantees a minimum reset timeout period of 140ms, with typical values up to 200ms and a maximum of 320ms over -40°C to +125°C. This variation is fully characterized and plotted in the Typical Operating Characteristics (Figure MAX6826 toc02), ensuring predictable µP initialization timing across industrial temperature ranges.
Can the watchdog timer in MAX6830YGUT+ be disabled, and how?
Yes, the watchdog timer in MAX6830YGUT+ is disabled by leaving the WDI pin unconnected or connecting it to a three-stated buffer output. Internally, an open WDI is driven low for 7/8 of the timeout period and high for 1/8, automatically clearing the timer every ~1.4s - effectively disabling watchdog supervision without firmware changes.
