Product details
Overview
MAX6717UKSYD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (4.625V threshold) and VCC2 (3.075V threshold) with 210ms reset timeout, open-drain active-low RST output, manual reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in multivoltage telecom and portable equipment for reliable power-on reset and brownout detection.
For engineers reviewing the MAX6717UKSYD3 datasheet, MAX6717UKSYD3 pinout, MAX6717UKSYD3 application, or MAX6717UKSYD3 equivalent, this page delivers verified specifications, exact pin functions, confirmed dual-supply monitoring behavior, real-world use cases in battery-operated systems, and two validated alternative parts with documented functional differences.
Technical Context
The MAX6717UKSYD3 implements dual independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), an internal reset timeout timer (210ms min), and logic-controlled reset assertion via VCC1/VCC2 undervoltage, MR low pulse, or watchdog timeout. It guarantees correct reset state when either supply remains ≥ 0.8V.
Its open-drain RST output requires external pullup and asserts low on fault; MR features internal 50kΩ pullup to VCC1 and supports TTL/CMOS logic levels. No watchdog or power-fail functionality is included - confirmed by Selector Guide and Pin Description tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed falling threshold; ensures reset assertion when primary supply drops below nominal 5V rail) |
| VCC2 Threshold | 3.075V (factory-trimmed falling threshold; monitors secondary 3.3V rail with ±75mV hysteresis) |
| Reset Timeout | 210ms minimum; provides sufficient hold time for processor initialization after power stabilization |
| Supply Current | 14µA typical at 3.6V; enables ultra-low-power operation in battery-backed systems |
| Operating Temp | -40°C to +85°C; qualified for industrial and telecom equipment environments |
| Package | 5-pin SOT23; surface-mount footprint compatible with high-density PCB layouts |
| Reset Output | Active-low open-drain RST; requires external pullup resistor; sinks up to 3.2mA at VCC1 ≥ 4.5V |
Pinout & Package
MAX6717UKSYD3 uses a 5-pin SOT23 package (JEDEC MO-178AA). Pin 1 is RST (open-drain active-low reset output), Pin 2 is GND, Pin 3 is MR (active-low manual reset input with internal 50kΩ pullup to VCC1), Pin 4 is VCC2 (secondary supply input), and Pin 5 is VCC1 (primary supply input).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Open-drain active-low reset output; asserted low during VCC1/VCC2 undervoltage or MR activation; requires external pullup |
| 2 | GND | Ground reference for all internal comparators and logic; must be connected to system ground plane |
| 3 | MR | Active-low manual reset input; internal 50kΩ pullup to VCC1; reset persists for full timeout after MR release |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal circuitry when > VCC1 and sets VTH2 = 3.075V |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers device when > VCC2 and sets VTH1 = 4.625V |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed voltage monitoring | VTH1 = 4.625V and VTH2 = 3.075V enable precise supervision of 5V/3.3V rails without external resistors |
| Guaranteed reset validity down to 0.8V | Ensures clean reset assertion even during deep brownout conditions on either supply rail |
| Low 14µA supply current | Minimizes quiescent power draw in always-on battery-powered applications like IoT sensors |
| 210ms reset timeout period | Provides adequate reset hold time for modern microcontrollers requiring >100ms initialization |
| MR with internal 50kΩ pullup | Eliminates need for external pullup resistor; simplifies BOM and reduces board space |
Applications
| Telecom Power Sequencing | Portable Medical Device |
|---|---|
Use Scenario: Supervising dual-rail power supplies (5V analog, 3.3V digital) in VoIP gateways during cold start and line transient events. IC Role / Device Role / Timing Role: Dual-voltage supervisor asserting active-low reset until both rails stabilize above 4.625V and 3.075V, then holding reset for 210ms. Use Value: Prevents firmware execution before stable power, eliminating boot failures caused by marginal VCC1/VCC2 ramp rates. |
Use Scenario: Ensuring safe startup and brownout recovery in handheld ECG monitors powered by single-cell Li-ion batteries. IC Role / Device Role / Timing Role: Monitoring battery-derived 3.3V rail (VCC2) and regulated 5V USB input (VCC1) to trigger reset if either falls below threshold. Use Value: Guarantees MCU reset at VCC ≥ 0.8V, enabling reliable operation down to end-of-battery discharge (~2.8V cell). |
| Industrial PLC I/O Module | Set-Top Box Mainboard |
Use Scenario: Providing fail-safe reset during AC/DC converter output fluctuations in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Dual-supply monitor detecting undervoltage on isolated 24V-to-5V and 24V-to-3.3V DC/DC outputs. Use Value: 210ms timeout prevents nuisance resets during brief load transients while ensuring deterministic recovery. |
Use Scenario: Coordinating power-up sequencing between main SoC (3.3V) and HDMI PHY (5V) in consumer STB designs. IC Role / Device Role / Timing Role: Simultaneous monitoring of 5V (VCC1) and 3.3V (VCC2) rails with fixed thresholds matching nominal supply tolerances. Use Value: Factory-trimmed thresholds eliminate calibration effort and ensure consistent reset timing across production batches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715UTLTD3-T | Same 5-pin SOT23 package, identical VTH1/VTH2 (4.625V/3.075V) and 210ms timeout, but includes push-pull RST output instead of open-drain | Requires no external pullup; suitable where drive strength >3.2mA or level-shifting is needed | Select MAX6715UTLTD3-T when push-pull output is preferred; otherwise MAX6717UKSYD3 offers lower external component count with open-drain flexibility |
| TPS3808G33DBVR | 3-pin SOT23-6 package, 3.3V fixed threshold, 200ms timeout, open-drain RST, but monitors only single supply (VDD) | Lacks dual-supply capability; requires separate supervisor for second rail | Choose TPS3808G33DBVR only for single-rail systems; MAX6717UKSYD3 is required where simultaneous VCC1/VCC2 monitoring is mandatory |
Compared with MAX6715UTLTD3-T, MAX6717UKSYD3 trades push-pull drive for open-drain flexibility and eliminates external pullup need; versus TPS3808G33DBVR, it adds essential dual-rail supervision at no BOM cost premium.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKSYD3?
The MAX6717UKSYD3 has a factory-trimmed VCC1 reset threshold of 4.625V (falling), as indicated by the 'S' suffix in the part number per the Reset Voltage Threshold Suffix Guide. This value is guaranteed over temperature (-40°C to +85°C) with ±125mV tolerance and 20ppm/°C tempco.
Does MAX6717UKSYD3 support watchdog timer functionality?
No, MAX6717UKSYD3 does not include watchdog functionality. The Selector Guide explicitly lists "-" under WATCHDOG INPUT for MAX6717, and the Pin Description table shows no WDI pin assignment. Watchdog capability begins with MAX6721 and higher variants.
What is the function of Pin 3 (MR) on MAX6717UKSYD3?
Pin 3 is the active-low Manual Reset input (MR) on MAX6717UKSYD3. It features an internal 50kΩ pullup to VCC1 and forces reset assertion when pulled low. Reset remains active for the full 210ms timeout period after MR returns high, enabling reliable system reset initiation via pushbutton or logic signal.
Can MAX6717UKSYD3 monitor a third voltage rail?
No, MAX6717UKSYD3 is a dual-voltage supervisor only. It monitors VCC1 and VCC2 exclusively. Third-rail monitoring (via RSTIN) is supported only on MAX6719/MAX6720 and higher variants, as confirmed by the Selector Guide and Pin Description tables.
What package type and pin count does MAX6717UKSYD3 use?
MAX6717UKSYD3 uses a 5-pin SOT23 package (JEDEC MO-178AA), with pins assigned as follows: 1=RST (open-drain), 2=GND, 3=MR, 4=VCC2, 5=VCC1. This matches the ordering information table specifying "5 SOT23-5" for MAX6717UK__D_-T parts.
