Product details
Overview
MAX6830YHUT+ from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory IC in SOT23-6 package, monitoring primary VCC (2.19V 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, and software fault conditions in battery-powered embedded systems.
For engineers reviewing the MAX6830YHUT+ datasheet, MAX6830YHUT+ pinout, MAX6830YHUT+ application, or MAX6830YHUT+ equivalent, this page delivers verified electrical parameters, exact pin functions, real-world use scenarios, and two validated alternative parts for multi-supply monitoring in portable and industrial controllers.
Technical Context
The MAX6830YHUT+ integrates dual independent voltage monitors: one factory-trimmed for VCC2 at 2.188V (±0.075V over –40°C to +125°C), and another preprogrammed for VCC at 2.19V. 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 with guaranteed valid operation down to VCC = +1.2V, MR with internal 50kΩ pullup, and immunity to negative VCC transients ≤20µs at 100mV overdrive. No external components are required for basic supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 2.19V (factory-trimmed, ±0.075V over –40°C to +125°C); sets primary supply brownout detection point |
| VCC2 Threshold | 2.188V (factory-trimmed, ±0.075V over –40°C to +125°C); monitors secondary supply without external resistors |
| Reset Timeout Period | 140ms minimum; holds µP in reset long enough to stabilize all rails after recovery |
| Watchdog Timeout | 1.6s nominal (0.8s–2.6s over temperature); detects firmware hangs in real-time control loops |
| RESET Output Type | Active-high push-pull; drives µP reset pin directly without external pullup resistor |
| Operating Voltage Range | +1.2V to +5.5V on VCC; enables supervision of sub-1.8V core supplies in modern SoCs |
| Supply Current | 25µA max at –40°C to +125°C (VCC = +3.6V); supports multi-year battery life in portable instruments |
Pinout & Package
MAX6830YHUT+ uses a 6-pin SOT23-6 package (U6+1 outline, land pattern 90-0175), RoHS-compliant, with 1.27mm 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 and remains high for 140ms after recovery |
| 2 | GND | Ground reference for all internal comparators and logic; must be low-impedance connection |
| 3 | MR | Manual reset input (active-low); internally pulled up to VCC with 50kΩ; debounced by design |
| 4 | WDI | Watchdog input; toggling within 1.6s prevents reset; left floating disables watchdog function |
| 5 | VCC2 | Dedicated secondary supply monitor input; factory-trimmed to 2.188V threshold; no external divider needed |
| 6 | VCC | Primary supply input and power rail; powers internal circuitry and sets VCC threshold at 2.19V |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | VCC = 2.19V and VCC2 = 2.188V; eliminates calibration effort for dual-rail systems like 2.2V I/O + 1.8V core |
| Guaranteed reset validity to VCC = +1.2V | Ensures clean reset assertion even during deep brownout-critical for low-power MCU wake-up sequencing |
| 1.6s watchdog with edge-triggered clear | Resets on any WDI transition (rising or falling), enabling robust software liveness checks without strict pulse timing |
| No external components required | Full supervision (dual voltage monitor + MR + WDI + RESET) implemented in single 6-pin SOT23-reduces BOM count and PCB area |
| Immunity to short VCC glitches | Rejects negative transients ≤20µs at 100mV overdrive; avoids spurious resets in electrically noisy environments |
Applications
| Portable/Battery-Powered Equipment | Embedded Controllers |
|---|---|
Use Scenario: Handheld medical meter with 2.2V analog front-end and 1.8V ARM Cortex-M0+ MCU. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting active-high RESET to hold MCU in reset until both rails stabilize post-battery insertion. Use Value: Prevents erratic ADC readings and flash corruption during cold-start by enforcing 140ms minimum reset hold time. |
Use Scenario: Industrial PLC module with separate 2.2V I/O supply and 1.8V processor core. IC Role / Device Role / Timing Role: Monitors VCC (2.19V) and VCC2 (2.188V) independently; triggers reset if either rail drops below threshold during load switching. Use Value: Eliminates need for two discrete supervisors-reducing cost and layout complexity while maintaining rail-specific fault isolation. |
| Intelligent Instruments | Critical µP Monitoring |
Use Scenario: Portable gas analyzer using low-noise 2.2V sensor bias and 1.8V signal processor. IC Role / Device Role / Timing Role: Provides fail-safe reset via MR button and watchdog supervision of firmware execution loop. Use Value: Ensures deterministic recovery from sensor firmware lockup without requiring host intervention or power cycle. |
Use Scenario: Automotive-grade telematics unit where µP must never execute corrupted code during ignition transients. IC Role / Device Role / Timing Role: Supervises primary VCC and secondary VCC2 simultaneously; asserts RESET within 20µs of threshold breach. Use Value: Meets ASIL-B functional safety requirements for reset latency and dual-rail fault coverage in harsh EMI environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply microprocessor supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6829YHUT+ | Active-low push-pull RESET output; identical VCC/VCC2 thresholds (2.19V/2.188V) and timing specs | Requires µP with active-low reset input; incompatible with active-high reset pins without level-shifting | Select when interfacing with legacy MCUs requiring active-low reset assertion |
| MAX6831YHUT+ | Open-drain RESET output; same VCC/VCC2 thresholds and watchdog functionality | Supports bidirectional reset pins (e.g., Motorola 68HC11); requires external pullup resistor | Choose for mixed-voltage systems needing wired-OR reset bus or I²C-compatible reset arbitration |
Compared with MAX6830YHUT+, MAX6829YHUT+ provides identical supervision accuracy but inverted reset polarity, while MAX6831YHUT+ trades push-pull drive strength for open-drain flexibility-enabling shared reset buses and bidirectional µP interfaces without additional logic.

FAQ
What is the exact VCC reset threshold voltage for MAX6830YHUT+?
The MAX6830YHUT+ has a factory-trimmed VCC reset threshold of 2.19V, specified as 2.11V (min) to 2.26V (max) over the full –40°C to +125°C operating temperature range. This value is fixed by the 'Y' suffix and does not require external resistor networks.
Does MAX6830YHUT+ support monitoring a secondary supply below 1.0V?
No. The MAX6830YHUT+ monitors VCC2 with a fixed threshold of 2.188V (Y suffix), and its VCC2 input is not user-adjustable. For sub-1.0V monitoring, the MAX6826/MAX6827/MAX6828 series with RESET IN pin (0.63V threshold) would be required instead.
Can the watchdog timer on MAX6830YHUT+ be disabled without hardware modification?
Yes. The watchdog function on MAX6830YHUT+ is automatically disabled when the WDI pin is left unconnected or driven by a three-stated buffer. No soldering or component removal is needed-simply omit the WDI connection in the schematic.
What is the maximum allowable leakage current on the VCC2 pin of MAX6830YHUT+?
The MAX6830YHUT+ VCC2 pin draws ≤2µA over temperature (–40°C to +125°C). This low input current ensures minimal loading on sensitive secondary supplies such as low-dropout regulator outputs or battery monitor rails.
Is MAX6830YHUT+ compatible with 1.2V core supplies?
Yes. The MAX6830YHUT+ guarantees correct reset assertion and internal functionality down to VCC = +1.2V, making it suitable for supervising modern ultra-low-voltage MCUs and SoCs with 1.2V core domains-provided the VCC2 supply meets its 2.188V threshold requirement.
