Product details
Overview
MAX6717UKVHD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (primary) and VCC2 (secondary) supplies with factory-trimmed reset thresholds - VTH1 = 4.625V (suffix 'V') and VTH2 = 3.075V (suffix 'H') - and providing 210ms minimum reset timeout (suffix 'D3'). It asserts an active-low open-drain RST output when either supply drops below its threshold and maintains reset for the full timeout after recovery. Used in multivoltage embedded systems requiring reliable power-up sequencing and brownout protection.
For engineers reviewing the MAX6717UKVHD3 datasheet, MAX6717UKVHD3 pinout, MAX6717UKVHD3 application, or MAX6717UKVHD3 equivalent, this page delivers verified electrical parameters, exact pin functions, confirmed dual-supply monitoring behavior, reset timing accuracy across temperature, and validated alternative parts for voltage supervisor selection in telecom, industrial, and portable equipment designs.
Technical Context
The MAX6717UKVHD3 implements two independent voltage comparators with internal 20ppm/°C tempco references, each feeding a shared reset timeout timer. Its open-drain RST output is referenced to VCC1 and guaranteed functional down to VCC1 or VCC2 ≥ 0.8V - enabling valid reset assertion during deep brownout conditions.
No watchdog, manual reset, power-fail, or RSTIN inputs are integrated in this variant (per Selector Guide: MAX6717 = 2 monitors, 1 open-drain RST, no WDI/MR/PFI/RSTIN). The device relies solely on VCC1/VCC2 monitoring and fixed 210ms timeout, eliminating external timing components and simplifying BOM for cost-sensitive dual-rail applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold (VTH1) | 4.625V (factory-trimmed, falling edge), ±1.5% tolerance - ensures reliable reset assertion before 5V system logic fails. |
| VCC2 Threshold (VTH2) | 3.075V (factory-trimmed, falling edge), ±1.5% tolerance - matches common 3.3V I/O rail monitoring with margin. |
| Reset Timeout (tRP) | 210ms (minimum), guaranteed over -40°C to +85°C - provides sufficient hold time for slow-starting processors and peripherals. |
| Supply Current (ICC) | 14µA typical at 3.6V - enables use in battery-backed or ultra-low-power always-on monitoring circuits. |
| Operating Voltage Range | VCC1/VCC2 = 0.8V to 5.5V - supports operation during severe undervoltage while maintaining reset validity. |
| Reset Output Type | Active-low open-drain RST - allows wired-OR configuration and level-shifting with external pullup to any logic rail. |
| Package | 5-pin SOT23 - footprint-compatible with space-constrained PCBs; thermal resistance θJA = 220°C/W. |
Pinout & Package
MAX6717UKVHD3 uses a 5-pin SOT23 package (JEDEC MO-178AA), with exposed pad not electrically connected. Pin 1 is marked by dot; pin numbering follows standard SOT23 convention (counterclockwise from mark).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; requires external pullup resistor (typically 10kΩ to VCC1); sinks ≥1.2mA at VCC1 ≥ 2.7V. |
| 2 | GND | Analog/digital ground reference; must be low-impedance connection to system ground plane. |
| 3 | MR | Not connected internally - unused pin; leave floating or tie to GND per layout best practice. |
| 4 | VCC2 | Secondary supply input (monitored at 3.075V); powers internal comparator for VCC2 path; must be ≥0.8V for valid reset. |
| 5 | VCC1 | Primary supply input (monitored at 4.625V); powers entire IC and references RST output; must be ≥0.8V for valid reset. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision eliminates need for two discrete supervisors or complex external divider networks. |
| Guaranteed reset validity down to 0.8V | Ensures deterministic reset assertion even during deep brownout - critical for fail-safe shutdown in industrial controllers. |
| Low 14µA supply current | Reduces quiescent power in always-on monitoring paths; enables >10-year battery life in coin-cell–powered backup circuits. |
| Open-drain RST with 1.2mA sink capability | Supports direct interface to 1.8V–5V logic families via pullup; eliminates level translators in mixed-voltage systems. |
| 210ms factory-programmed timeout | Eliminates external RC timing components - improves production yield, reduces bill-of-materials, and avoids temperature drift of discrete timers. |
Applications
| Industrial PLC Power Sequencing | Telecom Line Card Voltage Monitoring |
|---|---|
Use Scenario: Monitoring 5V primary and 3.3V I/O rails in programmable logic controller backplane modules during cold start and brownout events. IC Role / Device Role / Timing Role: Dual-rail supervisor asserting RST until both rails stabilize above 4.625V and 3.075V, then holding reset for 210ms to ensure FPGA configuration completion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715UTLTD3-T | 6-pin SOT23-6; includes manual reset (MR) input; same VTH1/VTH2 (4.625V/3.075V) and 210ms timeout. | Required where operator-initiated reset or test-mode reset is needed; adds PCB footprint and routing complexity. | Select MAX6715UTLTD3-T only if MR functionality is mandatory; otherwise MAX6717UKVHD3 offers smaller size and lower cost. |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only); push-pull RST; 200ms timeout; 2.5µA ICC; SOT23-5 package. | Only monitors one rail; lacks dual-threshold capability; unsuitable for systems requiring coordinated VCC1+VCC2 release. | Use TPS3808G33DBVR only for single-rail 3.3V applications; MAX6717UKVHD3 is irreplaceable for true dual-voltage coordination. |
Compared with MAX6715UTLTD3-T, MAX6717UKVHD3 saves board space and cost by omitting MR, while retaining identical dual-threshold accuracy and timing. Compared with TPS3808G33DBVR, it uniquely provides simultaneous 4.625V/3.075V monitoring in the same 5-pin footprint - enabling robust multirail sequencing without compromise.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKVHD3?
The MAX6717UKVHD3 has a factory-trimmed VCC1 reset threshold of 4.625V (falling edge), with ±1.5% tolerance over temperature. This value is encoded in the 'V' suffix per Maxim's Reset Voltage Threshold Suffix Guide and is verified in the Electrical Characteristics table under VTH1 parameter. The MAX6717UKVHD3 does not support adjustable thresholds - all thresholds are fixed at manufacture.
Does MAX6717UKVHD3 include a watchdog timer or manual reset input?
No, MAX6717UKVHD3 does not include a watchdog timer (WDI), manual reset input (MR), power-fail input/output (PFI/PFO), or adjustable RSTIN monitor. Per Maxim's Selector Guide, MAX6717 is defined as a dual-monitor device with only one open-drain RST output and no auxiliary inputs - confirmed by its 5-pin SOT23 pinout where pin 3 is NC.
What is the guaranteed minimum reset timeout period for MAX6717UKVHD3?
The MAX6717UKVHD3 guarantees a minimum reset timeout period of 210ms, as specified by the 'D3' suffix in its part number and confirmed in the Electrical Characteristics table under tRP (Reset Timeout Period). This value is production-tested and holds across the full -40°C to +85°C operating temperature range.
Can MAX6717UKVHD3 monitor a 1.8V supply as VCC2?
Yes, MAX6717UKVHD3 can monitor a 1.8V supply on VCC2, but only as a secondary rail - its VCC2 threshold is fixed at 3.075V (suffix 'H'), so a 1.8V rail would never trigger reset. To supervise 1.8V, a different variant (e.g., MAX6717UKTVD3 with VTH2 = 1.665V) must be selected. The MAX6717UKVHD3 is specifically configured for 4.625V/3.075V dual monitoring.
Is MAX6717UKVHD3 compatible with lead-free soldering processes?
Yes, MAX6717UKVHD3 is available in lead-free packaging. Per Maxim's Ordering Information, lead-free variants are ordered using the '+T' suffix instead of '-T'; thus the lead-free version is MAX6717UKVHD3+T. It complies with JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak reflow temperatures up to +260°C.
