Product details
Overview
MAX6717UKSHD3-T 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, push-pull active-low RST output, manual reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in multivoltage embedded systems requiring reliable power-on reset and brownout detection.
For engineers reviewing the MAX6717UKSHD3-T datasheet, MAX6717UKSHD3-T pinout, MAX6717UKSHD3-T application, or MAX6717UKSHD3-T equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temperature), ultra-low 14µA supply current at 3.6V, immunity to sub-20µs VCC transients, and compatibility with 1.8V/3.3V I/O domains in portable and industrial equipment.
Technical Context
The MAX6717UKSHD3-T integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a reset timeout timer (210ms min), and a manual reset input with internal 50kΩ pullup to VCC1. It asserts an active-low push-pull RST output when either supply falls below its threshold and holds reset for the full timeout after recovery.
No watchdog, RSTIN, PFI/PFO, or secondary RST2 functionality is present - confirmed by Selector Guide and Pin Configuration tables showing MAX6717 as 2-monitor, single open-drain/push-pull RST, MR-only variant in 5-pin SOT23. Reset logic remains valid down to 0.8V on either VCC pin, enabling robust operation during deep brownouts.
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 (minimum) - ensures sufficient hold time for slow-starting processors and peripherals during power-up |
| Supply Current | 14µA (typical at 3.6V) - minimizes quiescent load in battery-powered or energy-sensitive applications |
| Reset Output Type | Push-pull active-low - eliminates need for external pullup; drives directly into µP reset pin with VOH ≥ 0.8×VCC1 |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom environments without derating |
| VCC Validity Floor | 0.8V on VCC1 or VCC2 - guarantees correct reset state even during severe undervoltage conditions |
Pinout & Package
MAX6717UKSHD3-T uses a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm). The compact footprint supports high-density PCB layouts in space-constrained portable and networking equipment.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output - asserts low on fault and holds for 210ms; referenced to VCC1; no external pullup required |
| 2 | GND | Analog/digital ground reference - must be connected to system ground plane for stable comparator operation |
| 3 | MR | Active-low manual reset input - internal 50kΩ pullup to VCC1; pulse <1µs minimum width forces reset |
| 4 | VCC2 | Secondary supply input - powers internal circuitry when > VCC1; monitored at 3.075V threshold |
| 5 | VCC1 | Primary supply input - powers device when > VCC2; monitored at 4.625V threshold; defines VOH level |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators - eliminates need for discrete supervisors or resistor dividers |
| Guaranteed reset validity to 0.8V | Ensures deterministic reset behavior during deep brownouts where many supervisors fail - critical for fail-safe embedded control |
| Push-pull RST output | Drives µP reset pin directly without external components; supports 3.3V/5V I/O logic levels via VOH ≥ 0.8×VCC1 |
| Low 14µA supply current | Reduces standby power in always-on systems - enables >10-year battery life in coin-cell–powered IoT sensors |
| Immunity to short VCC transients | Rejects glitches <20µs duration (per typical characteristics), preventing spurious resets in noisy power environments |
Applications
| Industrial PLC Power Sequencing | Portable Medical Device Boot Integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316LUK46D3-T | Single-supply supervisor (4.63V only); no VCC2 monitoring; 200ms timeout; same SOT23-5 package | Requires external circuitry to monitor second rail - increases BOM count and board area | Select when only primary rail supervision is needed and cost sensitivity outweighs dual-monitoring benefit |
| TPS3808G33DBVR | Single-supply (3.3V threshold); 200ms timeout; push-pull RST; 1.8–6V VCC range; SOT23-5 | Lacks VCC2 input - cannot replace dual-rail monitoring without adding second IC or resistor divider | Choose for 3.3V-only systems where Maxim's 4.625V/3.075V pairing is unnecessary |
Compared with MAX6717UKSHD3-T, MAX6316LUK46D3-T reduces functionality to single-rail supervision but lowers unit cost, while TPS3808G33DBVR offers TI's process stability and automotive qualification but requires redesign to accommodate single-threshold architecture.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKSHD3-T?
The MAX6717UKSHD3-T has a factory-trimmed VCC1 reset threshold of 4.625V (minimum 4.500V, maximum 4.750V) with ±1.5% tolerance over -40°C to +85°C. This value is encoded in the "SH" suffix per Maxim's Reset Voltage Threshold Suffix Guide and is verified in the Electrical Characteristics table on page 2 of the datasheet.
Does MAX6717UKSHD3-T support watchdog functionality?
No, MAX6717UKSHD3-T does not include watchdog functionality. Per the Selector Guide and Functional Diagram, only MAX6721–MAX6729 variants support WDI input. The MAX6717UKSHD3-T is a dual-supply supervisor with manual reset (MR) only - confirmed by pin configuration (no WDI pin) and absence of watchdog timing parameters in its specification table.
What is the reset timeout period for MAX6717UKSHD3-T and how is it set?
The MAX6717UKSHD3-T has a reset timeout period of 210ms (minimum), set by the "D3" suffix in the part number per Maxim's Reset Timeout Period Suffix Guide. This value is guaranteed over temperature and supply voltage, and appears in the Electrical Characteristics table under tRP parameter with D3 designation.
Can MAX6717UKSHD3-T monitor a 1.8V supply as VCC2?
Yes, MAX6717UKSHD3-T supports VCC2 monitoring down to 0.9V, and its factory-trimmed VCC2 threshold is 3.075V - compatible with standard 3.3V rails. While it can accept 1.8V on the VCC2 pin (within 0.8V–5.5V absolute max), the 3.075V threshold means it will assert reset if VCC2 falls below that level; for 1.8V rail supervision, a different variant (e.g., "UH" suffix) would be required.
Is MAX6717UKSHD3-T pin-compatible with other MAX67xx SOT23-5 variants?
Yes, MAX6717UKSHD3-T shares the identical 5-pin SOT23-5 pinout with all MAX6715–MAX6718 variants (RST, GND, MR, VCC2, VCC1), as confirmed in the Pin Description table. However, functional compatibility depends on feature set - e.g., MAX6715 lacks push-pull RST, and MAX6719 adds RSTIN - so electrical behavior may differ despite mechanical compatibility.
