Product details
Overview
MAX6717AUKSYD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V) with factory-trimmed reset thresholds, 140ms minimum reset timeout, open-drain active-low RST output, and manual-reset input. It ensures reliable system boot and brownout recovery in battery-powered telecom and industrial controllers.
For engineers reviewing the MAX6717AUKSYD3+T datasheet, MAX6717AUKSYD3+T pinout, MAX6717AUKSYD3+T application, or MAX6717AUKSYD3+T equivalent, key selection criteria include dual-rail voltage monitoring capability, guaranteed reset validity down to 0.8V on either supply, low 14µA typical supply current at 3.6V, and compatibility with manual-reset and watchdog-free designs.
Technical Context
The MAX6717AUKSYD3+T implements independent dual-voltage comparators with hysteresis (0.5% of threshold), internal 20ppm/°C tempco, and a fixed 140ms reset timeout (suffix D3). It asserts RST low when either VCC1 or VCC2 falls below its factory-set threshold - VTH1 = 2.550V (R-suffix) and VTH2 = 2.550V (R-suffix) - and holds reset for the full timeout after both supplies recover.
No watchdog, power-fail, or adjustable RSTIN functions are included; this variant is optimized for cost-sensitive dual-supply monitoring without auxiliary inputs. Its open-drain RST output requires an external pullup and is referenced to VCC1, supporting direct interface with bidirectional µP reset pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 2.550V (min), factory-trimmed R-suffix; ensures reliable reset assertion during 2.5V rail brownout |
| VCC2 Reset Threshold | 2.550V (min), factory-trimmed R-suffix; matches VCC1 for symmetric dual-1.8V/2.5V or 2.5V/3.3V systems |
| Reset Timeout Period | 140ms (min); provides sufficient hold time for slow-starting µPs and peripheral initialization |
| Supply Current | 14µA (typ) at 3.6V; enables multi-year operation in coin-cell–powered IoT sensors |
| Operating Temperature | -40°C to +125°C; qualified for under-hood automotive and industrial control environments |
| Reset Output Type | Open-drain active-low RST; allows wired-OR reset bus sharing and level translation via external pullup |
| Valid Reset Down To | VCC1 or VCC2 ≥ 0.8V; guarantees deterministic reset state during deep brownout conditions |
Pinout & Package
MAX6717AUKSYD3+T is housed in a 6-pin SOT23-6 package (package code U6+1), with 0.95mm pitch, 2.9mm × 1.6mm footprint, and thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low open-drain reset output; asserted when VCC1 or VCC2 drops below threshold; requires external pullup to VCC1 or system rail |
| 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; pulse low ≥1µs to force reset |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V); powers internal VCC2 comparator and sets RST2 reference if enabled |
| 5 | VCC1 | Primary supply input (1.8V–5.0V); powers core logic, sets RST output reference, and pulls up MR |
| 6 | NC | No connect; internally unconnected; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitors | Simultaneous VCC1 and VCC2 supervision with separate thresholds avoids single-point failure in multirail systems |
| Factory-trimmed precision thresholds | VTH1 = VTH2 = 2.550V (R-suffix) with ±1.5% tolerance over temperature eliminates external resistor calibration |
| Guaranteed reset validity at 0.8V | Ensures correct RST logic state even during severe brownout-critical for fail-safe shutdown sequencing |
| Low 14µA supply current | Reduces standby power in always-on edge nodes; supports >10-year battery life with CR2032 |
| Open-drain RST with no internal pullup | Enables flexible reset bus topology, voltage-level translation, and shared reset line with multiple ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUKSVD3+T | VTH1 = 1.530V (V-suffix), VTH2 = 1.530V (V-suffix); same 140ms timeout, open-drain RST, 6-pin SOT23 | Optimized for 1.5V/1.8V dual-rail systems (e.g., LPDDR3 memory + ultra-low-power MCU) | Select when monitoring sub-1.8V rails; identical pinout and timing but lower thresholds reduce noise margin on higher rails |
| TLV803EB25DBZR | Single-supply supervisor (2.5V threshold only), SOT23-3, 200ms timeout, push-pull RST, 1.2µA IQ | Lacks dual-rail capability; suitable only where only one rail requires monitoring | Choose for lowest-cost single-rail replacement; not a functional substitute for dual-monitoring requirement of MAX6717AUKSYD3+T |
Compared with MAX6717AUKSYD3+T, MAX6715AUKSVD3+T offers lower voltage thresholds for advanced-node SoCs, while TLV803EB25DBZR reduces cost and quiescent current but sacrifices dual-supply functionality-making it unsuitable for systems requiring simultaneous VCC1/VCC2 validation.

FAQ
What is the exact reset threshold voltage for MAX6717AUKSYD3+T on VCC1 and VCC2?
The MAX6717AUKSYD3+T features factory-trimmed R-suffix thresholds: VCC1 reset threshold is 2.550V (min), and VCC2 reset threshold is also 2.550V (min), both with ±1.5% tolerance over -40°C to +125°C. These values are confirmed in the Electrical Characteristics table of the MAX6715A–MAX6729A datasheet Rev 6, page 2.
Does MAX6717AUKSYD3+T include a watchdog timer or power-fail input?
No, MAX6717AUKSYD3+T does not include watchdog (WDI), power-fail (PFI/PFO), or adjustable RSTIN functionality. It is a dedicated dual-supply supervisor with only VCC1, VCC2, MR, RST, and GND connections-verified by its 6-pin SOT23 pinout and absence of WDI/PFI/RSTIN pins in the Pin Description table (page 7).
What is the reset timeout period for MAX6717AUKSYD3+T, and is it adjustable?
The MAX6717AUKSYD3+T has a fixed 140ms minimum reset timeout period (suffix D3), as specified in the Reset Timeout Period Suffix Guide. This value is factory-programmed and not user-adjustable; no external capacitor or resistor modifies the timeout duration.
Can MAX6717AUKSYD3+T operate with VCC1 = 1.8V and VCC2 = 1.2V?
Yes, MAX6717AUKSYD3+T supports VCC1 from 1.8V to 5.0V and VCC2 from 0.9V to 3.3V per the General Description. At VCC1 = 1.8V and VCC2 = 1.2V, it maintains valid reset output logic down to 0.8V on either rail and draws ≤28µA total supply current (ICC1 + ICC2), as confirmed in the Electrical Characteristics table (page 2).
Is MAX6717AUKSYD3+T pin-compatible with other devices in the MAX6715A–MAX6729A family?
MAX6717AUKSYD3+T uses the 6-pin SOT23-6 (U6+1) package and shares identical pin assignments for VCC1, VCC2, GND, MR, and RST with other 6-pin variants like MAX6715AUKSVD3+T. However, pin compatibility does not imply functional equivalence-only devices with matching suffixes (e.g., D3 timeout, R threshold) provide identical behavior.
