Product details
Overview
MAX6717UKTGD3-T from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 5-pin SOT23 package, monitoring VCC1 (1.575V factory-trimmed threshold) and VCC2 (0.788V threshold) with 210ms minimum reset timeout, push-pull active-low RST output, manual reset input (MR), and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in portable battery-operated systems for reliable power-on reset and brownout detection.
For engineers reviewing the MAX6717UKTGD3-T datasheet, MAX6717UKTGD3-T pinout, MAX6717UKTGD3-T application, or MAX6717UKTGD3-T equivalent, this page delivers verified electrical parameters, exact pin functions, real-world use cases in multivoltage embedded systems, and two validated alternative parts with documented functional and timing differences.
Technical Context
The MAX6717UKTGD3-T integrates dual independent voltage comparators with factory-trimmed thresholds (VTH1 = 1.575V, VTH2 = 0.788V), a 210ms reset timeout timer, and a push-pull RST output referenced to VCC1. It asserts reset when either supply falls below its threshold and holds reset for ≥210ms after both supplies recover.
It features an internal 50kΩ pullup on MR, supports manual reset assertion with sub-µs pulse rejection, and guarantees correct RST logic state even when VCC1 or VCC2 drops to 0.8V - enabling robust operation during deep brownout conditions without external support circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 1.575V (typ), factory-trimmed - sets precise power-on reset point for primary 1.8V/2.5V rails |
| VCC2 Reset Threshold | 0.788V (typ), factory-trimmed - enables reliable monitoring of low-voltage core supplies (e.g., 0.9V–1.2V) |
| Reset Timeout Period | 210ms (min) - ensures µP completes full initialization before release from reset |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent power in always-on battery-backed systems |
| Operating Temperature | -40°C to +85°C - qualified for industrial and extended-temperature embedded applications |
| Reset Output Type | Push-pull active-low RST - eliminates need for external pullup resistor; drives directly into µP reset pin |
| MR Input Logic | Active-low with 50kΩ internal pullup to VCC1 - simplifies manual reset interface with momentary switch to GND |
Pinout & Package
MAX6717UKTGD3-T uses a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), surface-mount, lead-free compatible. Pin 1 is marked with dot; pin numbering follows standard SOT23 convention (counterclockwise from mark).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; sinks up to 3.2mA at VCC1 ≥ 4.5V; drives µP reset pin directly |
| 2 | GND | Ground reference for all internal comparators, timer, and output driver |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1 (50kΩ); accepts TTL/CMOS logic levels |
| 4 | VCC2 | Secondary supply input; powers internal circuitry when VCC2 > VCC1 and sets VTH2 comparator reference |
| 5 | VCC1 | Primary supply input; powers device when VCC1 > VCC2 and sets VTH1 comparator reference and RST output level |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed voltage monitoring | VTH1 = 1.575V (±1.5%), VTH2 = 0.788V (±1.5%) - eliminates external resistor networks and calibration effort |
| Guaranteed reset validity down to 0.8V | Operates correctly with VCC1 or VCC2 as low as 0.8V - ensures deterministic reset behavior during severe brownouts |
| 210ms minimum reset timeout | Fixed delay set by D3 suffix - meets typical µP boot-time requirements without external RC timing components |
| Push-pull RST output | No external pullup required; VOH ≥ 0.8×VCC1, VOL ≤ 0.4V - simplifies PCB layout and improves noise immunity |
| MR glitch rejection | 100ns minimum pulse rejection - prevents spurious resets from ESD or board-level noise on manual reset line |
Applications
| Portable Battery-Powered Devices | Industrial Microcontroller Systems |
|---|---|
Use Scenario: Power management in handheld medical meters with dual-rail (3.3V I/O, 1.2V core) and Li-ion battery input. IC Role / Device Role: Dual-supply supervisor ensuring safe µC startup and brownout recovery under varying battery voltage (3.0V–4.2V). Use Value: Prevents firmware corruption by holding reset until both rails stabilize above 1.575V and 0.788V, with 210ms margin for slow LDO settling. |
Use Scenario: PLC I/O module with isolated 5V logic rail and 3.3V FPGA configuration supply. IC Role / Device Role: System-level reset coordinator asserting reset if either rail dips below threshold due to load transients or aging regulators. Use Value: Push-pull RST drives FPGA PROG_B pin directly; MR allows field-service reset without power cycle. |
| Telecom Line Cards | Embedded Networking Gateways |
Use Scenario: 12V-to-3.3V/1.8V DC/DC-powered Ethernet switch ASIC subsystem. IC Role / Device Role: Dual-voltage monitor verifying both 3.3V I/O and 1.8V core supplies before releasing ASIC from reset. Use Value: Factory-trimmed thresholds eliminate tolerance stacking; 14µA ICC ensures minimal impact on standby power budget. |
Use Scenario: Wi-Fi 6 gateway with ARM SoC requiring coordinated reset across 1.1V CPU, 1.8V memory, and 3.3V PHY rails. IC Role / Device Role: Primary supervisor for critical 3.3V/1.8V pair; complements secondary supervisor for 1.1V rail. Use Value: 210ms timeout aligns with SoC boot ROM execution window; MR enables remote reset via GPIO-controlled switch. |
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 | Open-drain RST output (vs. push-pull); same VTH1/VTH2, 210ms timeout, 5-pin SOT23 | Requires external pullup resistor; suitable where reset line is shared with other open-drain devices (e.g., I²C bus reset) | Select when system architecture mandates wired-OR reset signaling or level translation is needed |
| TPS3808G18DBVR | Single-supply monitor (1.8V threshold only); 200ms timeout; 5-pin SOT23; 1.8V–6.5V VDD range | Monitors only one rail; lacks VCC2 input and dual-threshold capability - cannot replace dual-monitoring function | Use only if redesigning to single-rail supervision; not a drop-in replacement for MAX6717UKTGD3-T |
Compared with MAX6717UKTGD3-T, MAX6715UTLTD3-T offers identical monitoring accuracy and timing but requires external pullup, while TPS3808G18DBVR provides broader VDD range and lower ICC (1.4µA) but omits dual-voltage capability entirely - making it unsuitable for applications requiring simultaneous VCC1/VCC2 supervision.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKTGD3-T?
The MAX6717UKTGD3-T has a factory-trimmed VCC1 reset threshold of 1.575V (typical), with ±1.5% tolerance over temperature. This value is fixed by the "U" and "K" suffixes in the part number per Maxim's Reset Voltage Threshold Suffix Guide and is confirmed in the Electrical Characteristics table on page 2 of the datasheet. The MAX6717UKTGD3-T uses this precise threshold to monitor 1.8V supply rails during power-up and brownout events.
Does MAX6717UKTGD3-T support monitoring a third voltage rail?
No, the MAX6717UKTGD3-T is a dual-voltage supervisor and does not include RSTIN or PFI inputs. Its pinout (5-pin SOT23) and Selector Guide confirm it monitors only VCC1 and VCC2. For triple-voltage monitoring, Maxim offers the MAX6719/MAX6720 series (6-pin SOT23) with RSTIN input. The MAX6717UKTGD3-T is strictly limited to two monitored supplies and cannot be configured for auxiliary voltage sensing.
What is the function of the MR pin on MAX6717UKTGD3-T?
The MR (Manual Reset) pin on MAX6717UKTGD3-T is an active-low input with an internal 50kΩ pullup to VCC1. Pulling MR low forces an immediate reset assertion, which remains active for the full 210ms timeout period after MR returns high. It accepts standard TTL/CMOS logic levels and rejects pulses shorter than 100ns. In MAX6717UKTGD3-T, MR enables field-service reset without power cycling - a key feature for deployed industrial equipment.
Is MAX6717UKTGD3-T pin-compatible with other MAX67xx SOT23-5 variants?
Yes, MAX6717UKTGD3-T shares the identical 5-pin SOT23-5 footprint and pinout with MAX6715UTxxDx-T, MAX6716UTxxDx-T, MAX6718UKxxDx-T, and MAX6719UTxxDx-T. All use Pin 1=RST, Pin 2=GND, Pin 3=MR, Pin 4=VCC2, Pin 5=VCC1. However, output type (push-pull vs. open-drain) and threshold voltages differ - so electrical compatibility must be verified per application, even though mechanical layout is interchangeable.
What is the maximum supply voltage the MAX6717UKTGD3-T can tolerate on VCC1 and VCC2?
The MAX6717UKTGD3-T supports VCC1 and VCC2 voltages from 0.8V to 5.5V continuously, with absolute maximum ratings of -0.3V to +6V on both pins. Operation is fully specified across the 0.8V–5.5V range, and the device guarantees valid reset output logic as long as at least one supply remains ≥0.8V. This wide operating range allows use with 1.2V, 1.8V, 2.5V, 3.3V, and 5V rails without level-shifting.
