Product details
Overview
The MAX6829YGUT+ from Maxim Integrated is a dual ultra-low-voltage microprocessor supervisory circuit in SOT23-6 package, designed to monitor primary supply (VCC) and secondary factory-trimmed supply (VCC2) with 1.575V and 2.188V reset thresholds respectively, 140ms minimum reset timeout, manual reset input (MR), and watchdog timer (WDI). It ensures reliable power-on reset and brownout protection in battery-powered embedded systems.
For engineers reviewing the MAX6829YGUT+ datasheet, MAX6829YGUT+ pinout, MAX6829YGUT+ application, or MAX6829YGUT+ equivalent, this page delivers verified electrical parameters, exact SOT23-6 terminal mapping, confirmed dual-supply monitoring capability, and real-world design guidance for portable equipment, automotive subsystems, and multivoltage controllers.
Technical Context
The MAX6829YGUT+ integrates two independent voltage comparators-one for VCC (threshold = 1.575V ±25mV over -40°C to +125°C) and one factory-trimmed for VCC2 (2.188V ±25mV)-with a shared 140ms min reset timeout generator and 1.6s nominal watchdog timer. Its MR input features internal 50kΩ pullup and 200ns propagation delay.
Unlike MAX6826–MAX6828 variants, the MAX6829YGUT+ lacks RESET IN adjustability but provides fixed VCC2 monitoring via Pin 5, uses open-drain RESET output (Pin 1), and guarantees valid reset assertion down to VCC = +1.0V. It operates across -40°C to +125°C with BiCMOS process technology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Reset Threshold | 1.575V (±25mV, -40°C to +125°C); sets primary supply brownout detection point |
| VCC2 Reset Threshold | 2.188V (±25mV, -40°C to +125°C); factory-trimmed secondary supply monitor for 2.5V/1.8V I/O rails |
| Reset Timeout Period | 140ms minimum; ensures µP remains held in reset long enough for stable power recovery |
| Watchdog Timeout | 1.6s nominal; detects software lockup by requiring WDI edge within this window |
| Operating Voltage Range | +1.2V to +5.5V on VCC; supports operation down to 1.2V while maintaining reset validity |
| RESET Output Type | Open-drain; enables wired-OR configuration and compatibility with bidirectional µP reset pins |
| Supply Current (ICC) | 30µA max at -40°C to +125°C; enables ultra-low-power battery operation |
Pinout & Package
SOT23-6 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, RoHS-compliant lead-free finish (+T suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET (open-drain) | Active-low reset output; requires external pullup; asserts low during VCC/VCC2 undervoltage, MR low, or WDI timeout |
| 2 | GND | Ground reference for all internal comparators and logic; must be low-impedance connection |
| 3 | MR | Manual reset input; active-low with internal 50kΩ pullup; 200ns delay to RESET assertion |
| 4 | WDI | Watchdog input; edge-sensitive; clears internal 1.6s timer on rising/falling transition; disabled if floating |
| 5 | VCC2 | Secondary supply input; factory-trimmed comparator input for 2.188V threshold; not adjustable |
| 6 | VCC | Primary supply input; powers device and feeds 1.575V reset comparator; valid operation down to +1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneously supervises VCC (1.575V) and VCC2 (2.188V) with separate comparators-no shared reference error |
| Guaranteed reset validity to VCC = +1.0V | Ensures deterministic reset behavior during deep brownout, critical for Li-ion battery discharge endpoints |
| Immunity to short negative VCC transients | Withstands ≤20µs, 100mV VCC glitches without spurious reset-eliminates need for external filtering |
| No external components required | Full supervision functionality achieved with zero external resistors/capacitors-reduces BOM count and board area |
| 1.6s watchdog timer with edge-triggered clear | Prevents false timeouts during slow clock domains; cleared on any WDI transition-not just toggles |
Applications
| Portable Power Management | Automotive Body Control Module |

Use Scenario: Monitoring 3.3V main rail and 2.5V sensor interface rail in handheld medical diagnostic device powered by single-cell Li-ion. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting open-drain RESET to ARM Cortex-M0+ during simultaneous VCC drop and VCC2 sag below thresholds. Use Value: Prevents corrupted EEPROM writes during battery depletion by holding µP in reset until both rails stabilize above 1.575V and 2.188V respectively. |
Use Scenario: Supervising 5V infotainment MCU core supply and 3.3V CAN transceiver supply in vehicle door module. IC Role / Device Role / Timing Role: Detects VCC undervoltage during cold-crank (≤6V) and VCC2 dropout due to load dump, triggering 140ms reset hold. Use Value: Eliminates MCU lockup during engine start transient while maintaining CAN communication integrity via independent VCC2 monitoring. |

Use Scenario: Securing 2.5V FPGA configuration rail and 1.8V ADC reference rail in programmable logic controller backplane slot. IC Role / Device Role / Timing Role: Open-drain RESET tied to FPGA PROG_B and ADC RESET pins; MR connected to service button; WDI fed by FPGA heartbeat signal. Use Value: Enables field-serviceable reset initiation and firmware watchdog recovery without PCB redesign-leverages single SOT23-6 footprint. |
Use Scenario: Managing power sequencing for 1.2V BLE SoC core and 1.8V environmental sensor array in smartwatch. IC Role / Device Role / Timing Role: Monitors VCC (1.2V domain) and VCC2 (1.8V sensor rail); RESET drives shared reset net; WDI driven by SoC GPIO. Use Value: Guarantees synchronized reset release only after both voltage domains exceed their precise thresholds-prevents sensor initialization failure. |
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 |
|---|---|---|---|
| MAX6830YDUT+ | Active-high push-pull RESET output; identical VCC/VCC2 thresholds and timing | Requires level-shifting or µP with active-high reset input; incompatible with open-drain bus topologies | Select when system µP reset pin is active-high and no wired-OR reset net exists |
| TPS3808G15DBVR | Single-supply monitor (1.5V threshold only); no VCC2 input; 200ms reset timeout; SOT23-6 | Cannot supervise secondary rail; requires external resistor divider for dual-rail use; higher ICC (1.3µA typ) | Choose only if VCC2 monitoring is unnecessary and cost is primary constraint |
Compared with MAX6830YDUT+, the MAX6829YGUT+ enables open-drain reset sharing across multiple devices; compared with TPS3808G15DBVR, it delivers true dual-rail supervision without external components or timing compromise.

FAQ
What is the exact VCC2 reset threshold voltage for MAX6829YGUT+?
The MAX6829YGUT+ has a factory-trimmed VCC2 reset threshold of 2.188V, with ±25mV tolerance over the full -40°C to +125°C operating range. This value is laser-trimmed during production and specified in the Electrical Characteristics table under "VCC2 Reset Threshold (VTH2)" for suffix Y. It is not user-adjustable.
Does MAX6829YGUT+ support adjustable RESET IN monitoring like MAX6826?
No, the MAX6829YGUT+ does not support adjustable RESET IN monitoring. Its Pin 5 is dedicated to fixed VCC2 monitoring at 2.188V. The RESET IN function is exclusive to MAX6826/MAX6827/MAX6828 variants (which use Pin 5 for RSTIN). MAX6829YGUT+ uses Pin 5 solely as VCC2 input.
What is the watchdog timeout period for MAX6829YGUT+ and how is it cleared?
The MAX6829YGUT+ features a nominal 1.6s watchdog timeout period. The internal timer is cleared on any rising or falling edge at the WDI pin-not just toggles-enabling robust software supervision. It is also automatically cleared when RESET is asserted or MR is pulled low.
Can MAX6829YGUT+ operate reliably at VCC = +1.0V?
Yes, the MAX6829YGUT+ is guaranteed to assert a valid reset signal down to VCC = +1.0V. This is explicitly tested and specified in the Absolute Maximum Ratings and Electrical Characteristics tables, ensuring deterministic behavior during deep brownout conditions common in battery-powered systems.
What package type and lead finish does MAX6829YGUT+ use?
The MAX6829YGUT+ is supplied in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm) with lead-free (RoHS-compliant) finish. The "+" suffix in the part number confirms lead-free packaging per Maxim's ordering nomenclature, replacing the legacy "-T" suffix.
