Product details
Overview
MAX6717UKLTD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 5-pin SOT23 package, monitoring VCC1 (4.625V threshold) and VCC2 (3.075V threshold) with 210ms reset timeout, push-pull active-low RST output, manual reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used for reliable power-up sequencing and brownout protection in multivoltage embedded systems.
For engineers reviewing the MAX6717UKLTD3+ datasheet, MAX6717UKLTD3+ pinout, MAX6717UKLTD3+ application, or MAX6717UKLTD3+ equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temp), ultra-low 14µA supply current at 3.6V, immunity to sub-20µs VCC transients, and compatibility with 1.8V/3.3V core-I/O rail architectures.
Technical Context
The MAX6717UKLTD3+ integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a 210ms monolithic reset timeout timer, and a push-pull RST driver referenced to VCC1. It asserts reset when either supply falls below its threshold and holds reset for the full timeout after recovery.
It features an internal 50kΩ pullup on MR, supports manual reset pulse widths ≥1µs, guarantees valid reset logic state down to VCC1/VCC2 = 0.8V, and exhibits 20ppm/°C reset threshold tempco with 0.5% hysteresis - enabling robust operation across -40°C to +85°C industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed, ±1.5% over -40°C to +85°C) - sets precise power-good detection for 5V or 4.8V primary rails |
| VCC2 Threshold | 3.075V (factory-trimmed, ±1.5% over -40°C to +85°C) - enables accurate monitoring of 3.3V secondary supplies |
| Reset Timeout | 210ms (min) - ensures sufficient hold time for slow-start DC/DC converters and FPGA configuration |
| Supply Current | 14µA (typ at 3.6V) - minimizes quiescent load on battery-backed or low-power auxiliary rails |
| Reset Output Type | Push-pull active-low RST - eliminates need for external pullup and drives directly into µP reset pins |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom equipment environments without derating |
| VCC Validity Limit | Guaranteed reset logic validity down to VCC1 or VCC2 = 0.8V - supports brownout detection during deep undervoltage events |
Pinout & Package
MAX6717UKLTD3+ uses a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm, 0.95mm pitch) with gull-wing leads, RoHS-compliant lead-free finish (+T suffix), and thermal pad option not included.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; sinks 3.2mA at VCC1 ≥ 4.5V; asserts when VCC1 < 4.625V or VCC2 < 3.075V |
| 2 | GND | Analog/digital ground reference for all comparators, timer, and output drivers; must be low-impedance connection |
| 3 | MR | Active-low manual reset input with 50kΩ internal pullup to VCC1; reset asserted while MR = low and for full 210ms timeout after MR rises |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal circuitry when VCC2 > VCC1 and sets VTH2 comparator reference |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers internal circuitry when VCC1 > VCC2 and sets VTH1 comparator reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of VCC1 (4.625V) and VCC2 (3.075V) with separate comparators avoids single-point failure in multirail systems |
| Factory-trimmed precision thresholds | ±1.5% total accuracy over temperature eliminates need for external calibration or trimming resistors |
| 210ms monolithic reset timeout | Guaranteed minimum delay ensures reliable release after power stabilization, even with slow-rising supplies |
| Push-pull RST output | Direct-drive capability eliminates external pullup resistor, reduces BOM count, and improves noise immunity vs open-drain |
| Manual reset with internal pullup | 50kΩ internal VCC1-referenced pullup allows momentary switch-to-GND interface without external components |
| Ultra-low 14µA supply current | Enables use on always-on backup rails without compromising battery life in portable or energy-harvesting designs |

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+ | Open-drain RST output (vs push-pull), same thresholds/timing; requires external pullup resistor | Suitable where level-shifting or wired-OR reset bus is needed; less suitable for direct µP reset drive | Select when interfacing to bidirectional reset pins or multi-source reset buses |
| TPS3808G33DBVR | Single-supply monitor (3.3V only), 200ms timeout, 2.5µA ICC, SOT23-5; no VCC2 input or manual reset | Limited to single-rail systems; lacks dual-monitoring capability and MR functionality | Choose only for cost-sensitive 3.3V-only applications without manual reset requirement |
Compared with MAX6717UKLTD3+, MAX6715UTLTD3+ offers identical supervision logic but requires external pullup due to open-drain RST, while TPS3808G33DBVR reduces functionality to single-rail monitoring with lower ICC but eliminates dual-supply coordination and manual reset capability.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717UKLTD3+?
The MAX6717UKLTD3+ has factory-trimmed VCC1 reset threshold of 4.625V (±1.5% over -40°C to +85°C) and VCC2 threshold of 3.075V (±1.5%). These values are encoded in the "LT" suffix per Maxim's Reset Voltage Threshold Suffix Guide and verified in the Electrical Characteristics table of the official datasheet.
Does the MAX6717UKLTD3+ support manual reset, and how is it implemented?
Yes, the MAX6717UKLTD3+ includes an active-low manual reset (MR) input on Pin 3 with an internal 50kΩ pullup resistor to VCC1. Pulling MR low forces reset assertion for the full 210ms timeout period after MR returns high. No external components are required for basic operation - a momentary switch from MR to GND suffices.
What is the reset output type and drive capability of the MAX6717UKLTD3+?
The MAX6717UKLTD3+ features a push-pull active-low RST output on Pin 1, referenced to VCC1. It can sink up to 3.2mA when VCC1 ≥ 4.5V and VOL ≤ 0.4V, eliminating the need for an external pullup resistor and enabling direct connection to most µP reset inputs.
How does the MAX6717UKLTD3+ ensure reliable reset behavior during low-supply conditions?
The MAX6717UKLTD3+ guarantees valid reset logic state down to VCC1 or VCC2 = 0.8V - meaning RST remains correctly asserted or deasserted even during deep brownout events. This ensures deterministic system behavior when supplies collapse gradually, preventing undefined µP states.
What is the supply current consumption of the MAX6717UKLTD3+ across operating conditions?
The MAX6717UKLTD3+ draws 14µA typical supply current at 3.6V and +25°C, with ICC1 + ICC2 remaining below 39µA maximum across the full -40°C to +85°C range and 0.8V–5.5V supply range. This ultra-low ICC enables use on always-on backup rails without significant power penalty.
