Product details
Overview
MAX6717AUKVDD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (primary) and VCC2 (secondary) with factory-trimmed reset thresholds of 4.625V (VTH1) and 3.075V (VTH2), 1.1ms minimum reset timeout, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in telecom power management and industrial embedded systems for reliable brownout detection and system reset assertion.
For engineers reviewing the MAX6717AUKVDD3+T datasheet, MAX6717AUKVDD3+T pinout, MAX6717AUKVDD3+T application, or MAX6717AUKVDD3+T equivalent, key selection considerations include its dual-supply monitoring capability, open-drain active-low RST output, manual-reset input with internal 50kΩ pullup, watchdog disable-by-open feature, and operation across –40°C to +125°C.
Technical Context
The MAX6717AUKVDD3+T implements independent voltage comparators for VCC1 and VCC2, each referenced to precision internal bandgap references, with hysteresis of 0.5% and tempco of 20ppm/°C. It asserts an open-drain RST output when either supply falls below its threshold and holds reset for a fixed 1.1ms (min) timeout after both supplies recover.
This variant lacks RSTIN, WDI, PFI, and PFO functions - confirmed by its suffix "D3" (reset timeout) and "VDD3" (VTH1 = 4.625V / VTH2 = 3.075V), and pin configuration: Pin 1 = RST, Pin 2 = GND, Pin 3 = MR, Pin 4 = VCC2, Pin 5 = VCC1, Pin 6 = unused (no RST2). It supports only dual-supply supervision without auxiliary inputs or watchdog.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (typ), factory-trimmed - ensures reset assertion before 4.5V rail collapse in 5V-tolerant I/O domains. |
| VCC2 Reset Threshold | 3.075V (typ), factory-trimmed - matches common 3.3V logic supply tolerance for clean brownout detection. |
| Reset Timeout Period | 1.1ms (min), fixed - provides sufficient hold time for microprocessor initialization without excessive boot delay. |
| Supply Current | 15µA (typ) at 3.6V - enables battery-backed or low-power always-on supervision in portable equipment. |
| 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 flexible pullup voltage selection (e.g., 1.8V, 3.3V, or 5V). |
| MR Input Logic | Active-low with internal 50kΩ pullup to VCC1 - eliminates external components for manual reset button interface. |
Pinout & Package
SOT23-6 package (package code U6+1), 1.6mm × 2.9mm footprint, 0.95mm height, thermal resistance θJA = 115°C/W (multilayer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low open-drain reset output | Asserts low on VCC1/VCC2 undervoltage; requires external pullup; drives μP reset pin directly. |
| 2 - GND | Ground reference | Common return for all internal comparators, timers, and output drivers; must be low-impedance. |
| 3 - MR | Active-low manual-reset input | Pulled high internally to VCC1; pulling low forces immediate reset; debounced by 100ns glitch rejection. |
| 4 - VCC2 | Secondary supply input | Powers internal VCC2 comparator and sets VTH2 = 3.075V; must be ≥ 0.8V for valid reset operation. |
| 5 - VCC1 | Primary supply input | Powers core logic and sets VTH1 = 4.625V; also supplies MR pullup and RST driver reference. |
| 6 - NC | No connect | Unused pin; must remain floating or grounded per layout best practice - no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators avoids single-point failure. |
| Guaranteed reset validity down to 0.8V | Ensures correct RST logic state even during deep brownout - critical for fail-safe shutdown in industrial PLCs. |
| Immunity to short VCC transients | Rejects <20µs negative glitches (per typical characteristics), preventing spurious resets in noisy power environments. |
| Low 15µA supply current | Reduces standby power in always-on systems - e.g., remote sensors drawing <1µA average over duty cycle. |
| Factory-trimmed thresholds (±1.5%) | Eliminates external resistor networks and calibration; meets tight 5V/3.3V rail tolerance requirements out-of-box. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUKTVD3+T | VTH1 = 4.375V (M-suffix), same VTH2 = 3.075V, identical SOT23-6 pinout and timing. | Better suited for 4.5V nominal rails with tighter dropout margin; same industrial temperature range. | Select when primary supply is 4.5V ±5% rather than 5V ±10% - maintains 100mV hysteresis margin. |
| TLV809E33DBZR | Single-supply (3.3V only), no VCC2 monitoring, no MR input, SOT23-3 package, 200ms timeout. | Limited to single-rail systems; lacks manual reset and dual-threshold flexibility. | Use only in cost-sensitive, space-constrained designs where only 3.3V supervision is required. |
Compared with MAX6717AUKVDD3+T, MAX6715AUKTVD3+T offers lower VTH1 for tighter 4.5V rail tracking, while TLV809E33DBZR sacrifices dual-rail capability and manual reset for smaller size and lower unit cost - making MAX6717AUKVDD3+T optimal for robust dual-supply fail-safe systems.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6717AUKVDD3+T?
The MAX6717AUKVDD3+T has a factory-trimmed VCC1 reset threshold of 4.625V (typical), with min/max of 4.500V/4.750V over temperature. This value is encoded in the "VDD3" suffix and applies specifically to the MAX6717AUKVDD3+T - not the broader MAX6715A–MAX6729A family. The threshold remains stable with ±0.5% hysteresis and 20ppm/°C tempco.
Does the MAX6717AUKVDD3+T support watchdog timer functionality?
No, the MAX6717AUKVDD3+T does not include watchdog timer functionality. Its pinout omits WDI (pin 5 on watchdog variants), and the "VDD3" suffix confirms it belongs to the non-watchdog subgroup (MAX6715A/MAX6717A/MAX6719A series). Watchdog capability requires models like MAX6721AUKWD3+T - the MAX6717AUKVDD3+T is strictly a dual-supply voltage supervisor.
What is the function of Pin 6 on the MAX6717AUKVDD3+T?
Pin 6 on the MAX6717AUKVDD3+T is a no-connect (NC) terminal - it has no internal bond wire or circuit connection. Per Maxim's pin description table, this pin is unused across all MAX6717A variants. It must be left floating or tied to GND per PCB layout guidelines; connecting it to any signal risks undefined behavior or ESD path disruption.
Can the MAX6717AUKVDD3+T monitor a third voltage using RSTIN?
No, the MAX6717AUKVDD3+T does not support RSTIN functionality. The "VDD3" suffix and documented pin mapping confirm Pins 1–6 are assigned to RST, GND, MR, VCC2, VCC1, and NC - with no RSTIN terminal. Third-voltage monitoring requires variants like MAX6719AUKRVD3+T (which includes RSTIN on Pin 5) or MAX6723AUKRVD3+T.
What is the maximum sink current capability of the RST output on the MAX6717AUKVDD3+T?
The RST output on MAX6717AUKVDD3+T is an open-drain driver rated for 1.2mA sink current at VCC ≥ 2.7V (VOL ≤ 0.3V), and 3.2mA at VCC ≥ 4.5V (VOL ≤ 0.4V). These values are specified in the Electrical Characteristics table under "RST Output Low" conditions and define the maximum load the output can drive while maintaining valid logic-low voltage.
