Product details
Overview
MAX6717UKZWD3-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in SOT23-5 package, monitoring VCC1 (1.62V threshold) and VCC2 (2.313V threshold) with 210ms reset timeout, open-drain 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-up sequencing and brownout detection.
For engineers reviewing the MAX6717UKZWD3-T datasheet, MAX6717UKZWD3-T pinout, MAX6717UKZWD3-T application, or MAX6717UKZWD3-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/0.9V core-I/O rail architectures in portable and industrial equipment.
Technical Context
The MAX6717UKZWD3-T implements independent voltage comparators for primary (VCC1) and secondary (VCC2) supplies, each with factory-trimmed thresholds and 20ppm/°C tempco. Its reset logic asserts RST low when either supply falls below its threshold and holds for a guaranteed minimum 210ms after both rise above threshold.
It features an internal 50kΩ pullup on MR, supports TTL/CMOS-compatible manual reset triggering with 1µs minimum pulse width, and guarantees valid reset state even as VCC1 or VCC2 decays to 0.8V - enabling robust operation during deep brownouts without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 1.62V (typ), ±1.5% tolerance over -40°C to +85°C - sets precise brownout point for 1.8V I/O rails |
| VCC2 Threshold | 2.313V (typ), ±1.5% tolerance - monitors 2.5V or 3.3V auxiliary supplies with minimal headroom loss |
| Reset Timeout | 210ms (min), factory-set via D3 suffix - ensures µP completes full boot before release |
| Supply Current | 14µA (typ) at 3.6V - enables >10-year battery life in always-on monitoring applications |
| Reset Output Type | Open-drain active-low RST - allows wired-OR with other reset sources and flexible voltage-level translation |
| MR Input Logic | Active-low with 50kΩ internal pullup to VCC1 - eliminates external resistor for pushbutton reset interface |
| Valid Reset Range | Operates down to VCC1 or VCC2 = 0.8V - maintains deterministic reset assertion during severe undervoltage conditions |
Pinout & Package
MAX6717UKZWD3-T uses a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), optimized for space-constrained PCB layouts in portable and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low reset output | Open-drain driver referenced to VCC1; requires external pullup; asserts low on VCC1/VCC2 fault or MR activation |
| 2 - GND | Ground reference | Common return path for all internal comparators, reset timer, and MR pullup; must be low-impedance |
| 3 - MR | Manual reset input | Active-low input with internal 50kΩ pullup to VCC1; accepts TTL/CMOS levels; triggers reset for ≥1µs low pulse |
| 4 - VCC2 | Secondary supply input | Powers internal VCC2 comparator and sets secondary reset threshold (2.313V); also serves as reference for RST2 if present (not on this variant) |
| 5 - VCC1 | Primary supply input | Powers device core and sets primary reset threshold (1.62V); supplies internal pullup for MR and drives RST output high via external pullup |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (1.62V) and VCC2 (2.313V) supervision with separate comparators - eliminates need for two discrete supervisors |
| Factory-trimmed precision thresholds | ±1.5% total accuracy over temperature and supply - removes calibration overhead in production test |
| Guaranteed reset validity to 0.8V | Functional reset assertion even as VCC1 or VCC2 collapses to 0.8V - prevents spurious release during brownout recovery |
| Ultra-low quiescent current | 14µA typical at 3.6V - reduces system standby power by >90% vs. legacy supervisors |
| MR with integrated pullup | 50kΩ internal VCC1-referenced pullup - simplifies pushbutton interface and saves board space |
Applications
| Industrial PLC I/O Modules | Portable Medical Monitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G18DBVR | Single-supply monitor (1.8V only), push-pull RST, 200ms timeout, 1.6µA IQ | Lacks VCC2 monitoring; requires external resistor divider for secondary rail detection | Select when only primary 1.8V rail supervision is needed and ultra-low IQ dominates design priority |
| ADM6717AKSZ-REEL7 | Dual-supply (1.62V/2.32V), same SOT23-5, 200ms timeout, 18µA IQ, no MR input | Missing manual reset input; different reset timeout (200ms vs. 210ms); slightly higher supply current | Choose when MR functionality is unnecessary and 10ms timeout variance is acceptable in timing-critical boot sequences |
Compared with TPS3808G18DBVR and ADM6717AKSZ-REEL7, MAX6717UKZWD3-T uniquely delivers factory-trimmed dual-threshold supervision with integrated MR and 210ms timeout in a single SOT23-5 footprint - reducing BOM count and layout complexity for multirail systems requiring guaranteed brownout response.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKZWD3-T?
The MAX6717UKZWD3-T has a factory-trimmed VCC1 reset threshold of 1.62V (typical), with ±1.5% total accuracy over -40°C to +85°C and 0.5% hysteresis. This value is fixed by the "Z" suffix in the part number per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to the MAX6717UKZWD3-T variant - not inferred from adjacent family members.
Does MAX6717UKZWD3-T support monitoring a third voltage rail?
No, MAX6717UKZWD3-T is a dual-voltage supervisor and does not include RSTIN or PFI inputs. The MAX6719/MAX6720/MAX6723–MAX6727 variants provide RSTIN for adjustable third-rail monitoring, but MAX6717UKZWD3-T is limited to VCC1 and VCC2 only, as confirmed by its Selector Guide entry and Pin Configuration table.
What is the function of the MR pin on MAX6717UKZWD3-T and how should it be interfaced?
The MR pin on MAX6717UKZWD3-T is an active-low manual reset input with an internal 50kΩ pullup to VCC1. It triggers reset when pulled below 0.3×VCC1 for ≥1µs. For pushbutton use, connect one side to MR and the other to GND; no external resistor is needed. Leave MR unconnected if unused - the internal pullup ensures default high state.
What package type and dimensions does MAX6717UKZWD3-T use?
MAX6717UKZWD3-T uses a 5-pin SOT23-5 package measuring 2.9mm × 1.6mm × 1.1mm (body), with 0.95mm pitch and gull-wing leads. This compact outline is specified in Maxim's Ordering Information table and matches JEDEC MO-178AB standard - enabling high-density placement in portable and industrial PCBs.
Is MAX6717UKZWD3-T compatible with 1.2V core supplies?
Yes, MAX6717UKZWD3-T guarantees valid reset operation down to VCC1 or VCC2 = 0.8V, making it compatible with 1.2V core supplies. Its VCC2 threshold is 2.313V (for 2.5V/3.3V rails), but the device remains functional and asserts RST correctly even when VCC2 drops to 1.2V - as verified in Absolute Maximum Ratings and Detailed Description sections.
