Product details
Overview
MAX6830YDUT+T from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory IC in 6-pin SOT23 package, monitoring primary VCC (3.08V threshold) and secondary VCC2 (1.575V 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 hang conditions in battery-powered embedded systems.
For engineers reviewing the MAX6830YDUT+T datasheet, MAX6830YDUT+T pinout, MAX6830YDUT+T application, or MAX6830YDUT+T equivalent, key selection considerations include its factory-trimmed dual-threshold architecture, guaranteed reset validity down to VCC = +1.2V, immunity to short negative VCC transients, and compatibility with multivoltage systems requiring independent monitoring of core and I/O rails.
Technical Context
The MAX6830YDUT+T implements two independent voltage comparators-one for VCC (threshold = 3.08V ±3%, suffix T) and one for VCC2 (threshold = 1.575V ±3%, suffix V)-with internal hysteresis and temperature coefficient of 60 ppm/°C. Its reset logic asserts active-high RESET when either supply falls below its threshold, MR is pulled low, or WDI fails to toggle within 1.6s.
It features a dedicated VCC2 monitor pin (Pin 5), eliminating external resistor dividers for secondary rail supervision, and uses BiCMOS process (750 transistors) to achieve 25µA max ICC at -40°C to +125°C while maintaining reset assertion down to VCC = +1.2V. The push-pull RESET output sources up to 800µA at VCC ≥ 4.75V and maintains VOH ≥ 0.8 × VCC across operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 3.08V ±3% (T-suffix); ensures precise reset initiation on main supply brownout at 3.3V systems |
| VCC2 Threshold | 1.575V ±3% (V-suffix); factory-trimmed for direct monitoring of 1.5V/1.6V core supplies without external components |
| Reset Timeout Period | 140ms minimum; guarantees µP remains held in reset long enough for stable power recovery |
| Watchdog Timeout | 1.6s nominal; detects firmware lockup by requiring WDI edge every ~1.6s |
| Operating Temperature | -40°C to +125°C; qualified for industrial and automotive under-hood environments |
| Supply Current (ICC) | 25µA max at -40°C to +125°C; enables multi-year battery life in portable equipment |
| RESET Output Type | Active-high push-pull; eliminates need for external pull-up and supports direct interface to µP reset inputs |
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, low only during reset assertion |
| 2 | GND | Ground reference for all internal comparators and logic; must be low-impedance connection |
| 3 | MR | Manual-reset input (active-low); internal 50kΩ pullup allows direct switch-to-GND connection without external bias |
| 4 | WDI | Watchdog input; toggling within 1.6s prevents reset; left floating or three-stated disables watchdog |
| 5 | VCC2 | Secondary supply monitor input; connects directly to 0.9V–2.5V rail; no external divider required |
| 6 | VCC | Primary supply monitor input; powers internal circuitry and sets VCC2 comparator reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | VCC = 3.08V and VCC2 = 1.575V; eliminates calibration effort and component count vs. adjustable supervisors |
| Guaranteed reset validity to VCC = +1.2V | Ensures deterministic reset behavior even during deep brownout-critical for fail-safe embedded control |
| 1.6s watchdog with glitch-immune WDI | Detects 50ns pulses; immune to noise-induced false triggers while catching sustained firmware hangs |
| No external components required | Integrates pullup on MR, precision references, timeout delay, and dual comparators-reduces BOM and layout area |
| Immunity to short negative VCC transients | Withstands ≤20µs glitches down to 100mV below threshold without spurious reset-enhances system robustness |
Applications
| Portable/Battery-Powered Equipment | Embedded Controllers |
|---|---|
Use Scenario: Wearable health monitor with 3.3V main rail and 1.5V sensor core supply, operating on coin-cell battery. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting active-high RESET to ARM Cortex-M0 during VCC or VCC2 brownout. Use Value: 25µA max ICC extends battery life; factory-trimmed thresholds eliminate calibration drift over temperature and time. |
Use Scenario: Industrial PLC controller with separate 3.3V I/O and 1.5V FPGA core supplies. IC Role / Device Role / Timing Role: Monitors both rails independently; holds µP in reset until both stabilize post-power-cycle. Use Value: 140ms min timeout prevents premature boot; push-pull RESET avoids weak pull-up conflicts in noisy EMI environments. |
| Intelligent Instruments | Critical µP Monitoring |
Use Scenario: Handheld multimeter with auto-ranging ADC powered by 3.3V rail and 1.5V reference buffer. IC Role / Device Role / Timing Role: Ensures ADC reference is stable before µP initiates measurement sequence. Use Value: VCC2 = 1.575V threshold matches 1.5V reference tolerance; 60 ppm/°C hysteresis prevents chatter near trip point. |
Use Scenario: Medical infusion pump requiring fail-safe restart after power interruption. IC Role / Device Role / Timing Role: Watchdog monitors motor control firmware; MR enables clinician-initiated hard reset. Use Value: 1.6s watchdog timeout balances responsiveness vs. false trigger risk; MR internal 50kΩ pullup simplifies front-panel design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6827YDUT+T | VCC threshold = 2.93V (S-suffix); same VCC2 = 1.575V, push-pull active-high RESET | Better suited for 2.8V–3.0V main supplies; less margin for 3.3V systems with ripple | Select when primary rail is 2.85V nominal (e.g., LiFePO₄ battery systems) |
| MAX6831YDUT+T | Open-drain RESET output; identical VCC/VCC2 thresholds and watchdog | Required for bidirectional µP reset pins (e.g., Motorola 68HC11); needs external pull-up | Choose only if interfacing with legacy µPs mandating open-drain reset signaling |
Compared with MAX6827YDUT+T and MAX6831YDUT+T, the MAX6830YDUT+T provides optimal voltage margin for standard 3.3V systems while delivering the simplest interface (no pull-up needed) and highest noise immunity due to push-pull drive strength.

FAQ
What is the exact VCC and VCC2 reset threshold voltage for MAX6830YDUT+T?
The MAX6830YDUT+T has a VCC reset threshold of 3.08V ±3% (T-suffix) and a VCC2 reset threshold of 1.575V ±3% (V-suffix), both specified over -40°C to +125°C. These factory-trimmed values are confirmed in the Electrical Characteristics table of the MAX6826–MAX6831 datasheet, page 2 (VTH) and page 3 (VTH2), and apply directly to the MAX6830YDUT+T ordering variant.
Does MAX6830YDUT+T support operation down to VCC = +1.0V?
The MAX6830YDUT+T is guaranteed to assert valid RESET down to VCC = +1.2V over -40°C to +125°C (per datasheet Absolute Maximum Ratings and Electrical Characteristics). While the general MAX6826–MAX6831 family is rated to +1.0V at 0°C to +85°C, the MAX6830YDUT+T's minimum operational VCC is +1.2V across its full industrial temperature range.
What is the function of Pin 5 (VCC2) on MAX6830YDUT+T?
Pin 5 on MAX6830YDUT+T is the VCC2 input, dedicated to monitoring a secondary supply rail at 1.575V. Unlike MAX6826–MAX6828 variants, it does not accept an adjustable resistor-divider network-instead, it uses an internal factory-trimmed comparator optimized for 0.9V–2.5V rails, eliminating external components for secondary-supply supervision.
Can MAX6830YDUT+T be used with a 3.3V µP that requires active-low reset?
Yes, MAX6830YDUT+T can interface with active-low µP reset inputs using an external inverter or level-shifter, since its native RESET output is active-high push-pull. Direct connection is not possible without signal inversion; alternatives like MAX6826YDUT+T (active-low push-pull) or MAX6829YDUT+T (active-low with VCC2) would be drop-in replacements for active-low requirements.
What is the watchdog timeout period for MAX6830YDUT+T and how is it cleared?
The MAX6830YDUT+T features a nominal 1.6s watchdog timeout period (min 1.12s, max 2.4s over -40°C to +85°C). The internal timer is cleared by any rising or falling edge on WDI (Pin 4), by assertion of MR (Pin 3), or by RESET output assertion-ensuring immediate recovery from firmware hangs without requiring precise timing windows.
