Product details
Overview
MAX6830VDUT+ from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, designed to monitor primary supply (VCC) at 1.58V and secondary supply (VCC2) at 1.575V with ±0.045V tolerance over –40°C to +125°C, assert active-high push-pull RESET on fault, and support manual reset and 1.6s watchdog timeout - used in battery-powered embedded controllers requiring reliable brownout detection.
For engineers reviewing the MAX6830VDUT+ datasheet, MAX6830VDUT+ pinout, MAX6830VDUT+ application, or MAX6830VDUT+ equivalent, key selection criteria include its factory-trimmed dual-threshold monitoring (VCC = 1.58V, VCC2 = 1.575V), guaranteed reset validity down to VCC = +1.2V, push-pull RESET output with 0.3V VOL @ 1.2V/100µA, and immunity to negative VCC transients ≤20µs at 100mV overdrive.
Technical Context
The MAX6830VDUT+ integrates two independent voltage comparators - one for VCC (1.58V threshold) and one for VCC2 (1.575V threshold) - with hysteresis of 2×VTH and temperature coefficient of 60ppm/°C. Its internal 1.6s watchdog timer clears on any WDI edge and triggers reset if no transition occurs within timeout.
It features an internal 50kΩ MR pullup, supports CMOS-level manual reset input, and asserts RESET for ≥140ms after all monitored supplies recover. The push-pull RESET output sources 0.8×VCC at ISOURCE = 1µA (reset asserted) and sinks 0.3V at ISINK = 100µA (reset asserted), with valid operation across full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Threshold | 1.58V (min 1.521V, max 1.629V at –40°C to +125°C) - sets primary supply brownout detection point for 1.53V–2.0V systems |
| VCC2 Threshold | 1.575V (min 1.521V, max 1.629V at –40°C to +125°C) - factory-trimmed secondary supply monitor for core/logic rails |
| Reset Timeout Period | 140ms minimum - ensures µP remains held in reset long enough for power stabilization after recovery |
| Watchdog Timeout | 1.6s nominal (0.80s–2.60s over temperature) - provides fail-safe software execution monitoring |
| RESET Output Type | Active-high push-pull - eliminates external pullup, drives high/low directly, compatible with µP reset inputs requiring active-high assertion |
| Supply Current (ICC) | 25µA max at –40°C to +125°C, VCC = +1.8V - enables multi-year battery life in portable equipment |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and harsh-environment embedded use |
Pinout & Package
Package: 6-pin SOT23 (U6+1 outline, land pattern 90-0175), RoHS-compliant, lead-free (+T suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull reset output - asserts high during fault condition; sinks 0.3V @ 100µA when asserted, sources 0.8×VCC when deasserted |
| 2 | GND | Ground reference - common return path for VCC, VCC2, MR, WDI, and RESET |
| 3 | MR | Manual-reset input, active-low - internal 50kΩ pullup to VCC; 1µs minimum pulse width; 100ns glitch rejection |
| 4 | WDI | Watchdog input - toggling within 1.6s prevents reset; unconnected or three-stated disables watchdog |
| 5 | VCC2 | Secondary supply input - factory-trimmed comparator input for monitoring 0.9V–2.5V rails (1.575V threshold for MAX6830VDUT+) |
| 6 | VCC | Primary supply input - factory-trimmed comparator input for monitoring 1.53V–2.0V rails (1.58V threshold for MAX6830VDUT+) |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed voltage monitoring | VCC = 1.58V and VCC2 = 1.575V thresholds with ±0.045V tolerance over full temperature range - eliminates external resistor dividers for precise dual-rail supervision |
| Guaranteed reset validity down to VCC = +1.2V | Ensures reliable reset assertion even during deep brownout conditions where many supervisors lose functionality |
| 1.6s watchdog timer with edge-triggered clear | Prevents runaway code by requiring periodic WDI transitions - immune to stuck-at logic states |
| Push-pull active-high RESET output | Directly interfaces with µPs requiring active-high reset (e.g., ARM Cortex-M series), eliminating need for level-shifting or pullup resistors |
| No external components required | Integrates precision references, comparators, delay timers, and driver - reduces BOM count and PCB area vs. discrete solutions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6827SDUT+ | VCC threshold = 2.93V (not 1.58V); same 6-pin SOT23, push-pull active-high RESET, identical watchdog and MR specs | Designed for 3.3V systems - unsuitable for 1.5V/1.8V dual-rail monitoring without external scaling | Select MAX6827SDUT+ only when primary supply is ≥2.85V; MAX6830VDUT+ is mandatory for sub-1.8V VCC supervision. |
| TPS3808G15DBVR | Single-supply monitor (1.5V threshold), open-drain RESET, no VCC2 input, 200ms timeout, 1.25µA IQ | Lacks dual-monitoring capability and manual reset - requires external circuitry to replicate MAX6830VDUT+ functionality | Use TPS3808G15DBVR only for cost-sensitive single-rail applications; MAX6830VDUT+ remains optimal for integrated dual-supply + watchdog + MR. |
Compared with MAX6827SDUT+, MAX6830VDUT+ provides lower-voltage dual-rail supervision essential for modern low-power MCUs, while versus TPS3808G15DBVR it delivers complete system-level supervision (dual voltage, watchdog, MR) in one chip - reducing design complexity and board space.

FAQ
What is the exact VCC and VCC2 reset threshold voltage for MAX6830VDUT+?
The MAX6830VDUT+ has a factory-trimmed VCC reset threshold of 1.58V (min 1.521V, max 1.629V over –40°C to +125°C) and a VCC2 reset threshold of 1.575V (min 1.521V, max 1.629V over temperature). These values are specified in the Electrical Characteristics table under "VCC Reset Threshold" and "VCC2 Reset Threshold" with suffix 'V', confirming precise matching for 1.5V–1.8V dual-rail systems.
Does MAX6830VDUT+ support active-high or active-low reset output?
MAX6830VDUT+ provides an active-high push-pull RESET output. When a fault occurs (VCC or VCC2 drops below threshold, MR pulled low, or watchdog times out), RESET goes high and remains high for ≥140ms after recovery. This is confirmed in the Pin Description table and Selector Guide, which designate MAX6830 as having "ACTIVE-HIGH RESET".
Can MAX6830VDUT+ monitor two independent supply rails simultaneously?
Yes, MAX6830VDUT+ monitors two independent rails: VCC (primary, 1.58V threshold) on pin 6 and VCC2 (secondary, 1.575V threshold) on pin 5. Both comparators operate concurrently, and RESET asserts if either falls below its respective threshold - a core feature documented in the General Description and Selector Guide.
What is the watchdog timeout period for MAX6830VDUT+ and how is it cleared?
The watchdog timeout period for MAX6830VDUT+ is 1.6s nominal (0.80s–2.60s over –40°C to +125°C). It is cleared by any rising or falling edge on the WDI pin (pin 4), or automatically by assertion of RESET or MR. Leaving WDI unconnected disables the watchdog, as stated in the Pin Description and Applications Information sections.
Is MAX6830VDUT+ compatible with systems requiring reset assertion down to VCC = +1.0V?
No - MAX6830VDUT+ guarantees valid reset operation down to VCC = +1.2V (not +1.0V). The datasheet specifies "VCC Operating Voltage Range: 1.2V to 5.5V at –40°C to +125°C", and the Electrical Characteristics table confirms reset functionality starts at 1.2V. For 1.0V operation, MAX6826/MAX6827 variants must be selected.
