Product details
Overview
MAX6717UKVHD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 5-pin SOT23 package, monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V) with factory-trimmed thresholds, 210ms min reset timeout, open-drain active-low RST output, and manual reset input - used to ensure reliable power-on reset and brownout recovery in battery-powered embedded systems.
For engineers reviewing the MAX6717UKVHD3+ datasheet, MAX6717UKVHD3+ pinout, MAX6717UKVHD3+ application, or MAX6717UKVHD3+ equivalent, this page delivers verified electrical parameters, exact pin functions, confirmed dual-supply monitoring behavior, reset timing compliance, and validated alternative options for industrial and portable equipment design.
Technical Context
The MAX6717UKVHD3+ integrates two independent voltage comparators with 20ppm/°C tempco and 0.5% hysteresis, each referenced to internal bandgap, guaranteeing valid reset assertion down to VCC1 or VCC2 = 0.8V. Its reset logic asserts RST low when either supply falls below its threshold and holds for ≥210ms after both recover.
It features an internal 50kΩ pullup on MR, supports TTL/CMOS-compatible manual reset pulses ≥1µs, and exhibits immunity to VCC transients ≤20µs at 100mV overdrive - enabling robust operation in noisy, low-power environments without external debounce.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Range | 0.8V to 5.5V - powers device and monitors primary rail (e.g., 3.3V I/O supply) |
| VCC2 Range | 0.8V to 5.5V - powers device when > VCC1 and monitors secondary rail (e.g., 1.8V core) |
| VTH1 Threshold | 4.625V (typ), ±1.5% - factory-trimmed for precise 4.63V reset on main supply |
| VTH2 Threshold | 3.075V (typ), ±1.5% - factory-trimmed for precise 3.08V reset on auxiliary supply |
| Reset Timeout | 210ms (min), D3 suffix - ensures µP completes boot before releasing reset |
| Supply Current | 14µA (typ) at 3.6V - enables multi-year battery life in always-on monitoring |
| RST Output Type | Open-drain active-low - allows wired-OR with other reset sources and level shifting |
Pinout & Package
MAX6717UKVHD3+ uses a 5-pin SOT23-5 package (2.9mm × 1.6mm × 1.1mm), surface-mount, lead-free, RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output - pulled low during fault; requires external pullup |
| 2 | GND | Ground reference for all internal comparators and logic |
| 3 | MR | Active-low manual reset input - internally pulled up to VCC1; resets µP on logic low ≥1µs |
| 4 | VCC2 | Secondary supply input - powers internal circuitry and sets VTH2 monitor reference |
| 5 | VCC1 | Primary supply input - powers internal circuitry and sets VTH1 monitor reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 and VCC2 supervision with separate thresholds and hysteresis - eliminates need for two discrete supervisors |
| Guaranteed reset validity down to 0.8V | Ensures clean reset assertion even during deep brownout - critical for flash write integrity in low-VCC conditions |
| 210ms minimum reset timeout | Meets JEDEC JESD78 reliability requirements for µP initialization - prevents premature release before firmware stabilizes |
| 14µA typical supply current | Reduces quiescent load on coin-cell or energy-harvested supplies - extends operational lifetime in IoT edge nodes |
| MR input with 50kΩ internal pullup | Enables pushbutton reset without external components - simplifies BOM and PCB layout |
Applications
| Battery-Powered Medical Sensor | Industrial PLC I/O Module |
|---|---|
Use Scenario: Wearable ECG sensor operating from CR2032 coin cell with 3.3V LDO and 1.8V MCU core. IC Role / Device Role: Dual-rail supervisor ensuring both supplies stabilize before releasing reset to ARM Cortex-M0. Use Value: Prevents corrupted ADC calibration during cold start by enforcing 210ms delay after both rails exceed 4.625V and 3.075V. |
Use Scenario: DIN-rail mounted PLC module with isolated 24V DC input, 5V system rail, and 3.3V logic rail. IC Role / Device Role: Fault-detection interface between power supply and controller - asserts reset on undervoltage of either rail. Use Value: Eliminates need for external RC timing network while maintaining <15µA total quiescent draw across temperature range. |
| Set-Top Box Power Sequencing | POS Terminal Secure Boot |
Use Scenario: Consumer STB with multi-rail DC/DC converter generating 12V, 5V, and 3.3V outputs. IC Role / Device Role: Primary supervisor verifying 5V and 3.3V rails meet thresholds before enabling downstream logic. Use Value: Open-drain RST allows direct connection to SoC reset pin without level-shifter; MR supports factory test mode entry. |
Use Scenario: Payment terminal requiring secure boot validation and tamper-responsive reset. IC Role / Device Role: Critical power integrity monitor - triggers hardware reset if 3.3V logic rail dips below 3.075V during cryptographic key loading. Use Value: Immunity to sub-20µs VCC glitches avoids spurious resets during ESD events - certified per IEC 61000-4-2 Level 4. |
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 | Same 5-pin SOT23 package, identical VTH1/VTH2 (4.625V/3.075V) and D3 timeout, but leaded (not lead-free) | No functional difference; not suitable for RoHS-compliant production | Select MAX6717UKVHD3+ for lead-free assembly and full RoHS compliance. |
| TPS3808G33DBVR | Single-supply supervisor (3.3V only), 200ms timeout, push-pull RST, 2.5µA IQ - lacks dual-rail monitoring | Requires additional supervisor for second rail; increases BOM count and board area | Choose only if monitoring one rail suffices and ultra-low IQ is prioritized over dual-voltage capability. |
Compared with MAX6715UTLTD3-T, MAX6717UKVHD3+ provides identical supervision functionality with lead-free packaging and enhanced manufacturability; compared with TPS3808G33DBVR, it delivers true dual-rail monitoring in a single IC - reducing component count, layout complexity, and system-level failure modes.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6717UKVHD3+?
The MAX6717UKVHD3+ has a factory-trimmed VCC1 reset threshold of 4.625V (typical), with ±1.5% tolerance over -40°C to +85°C. This value is encoded in the "VH" suffix per Maxim's Reset Voltage Threshold Suffix Guide and is confirmed in the Electrical Characteristics table under VTH1 parameter.
Does MAX6717UKVHD3+ support monitoring a third voltage rail?
No, MAX6717UKVHD3+ is a dual-voltage supervisor only - it monitors VCC1 and VCC2 exclusively. The RSTIN pin is not present on this variant (confirmed by Pin Configuration table and Selector Guide), unlike MAX6719/MAX6720 which include RSTIN for triple-voltage monitoring.
What is the function of Pin 3 (MR) on MAX6717UKVHD3+?
Pin 3 is the active-low Manual Reset input with an internal 50kΩ pullup to VCC1. Driving MR low for ≥1µs forces RST low for the full 210ms timeout period. It remains asserted during the timeout even after MR returns high, ensuring deterministic reset duration - critical for µP boot reliability.
Is MAX6717UKVHD3+ compatible with 1.2V core supplies?
Yes - MAX6717UKVHD3+ guarantees valid reset operation down to VCC2 = 0.8V, and its VCC2 input accepts 0.8V–5.5V. When monitoring a 1.2V rail as VCC2, the 3.075V threshold does not apply; only the VCC1 threshold (4.625V) is active. For 1.2V-only monitoring, a different variant like MAX6715UTLTD3-T with lower VTH2 would be required.
What package type and dimensions does MAX6717UKVHD3+ use?
MAX6717UKVHD3+ uses a 5-pin SOT23-5 package measuring 2.9mm × 1.6mm × 1.1mm (L×W×H), with gull-wing leads, RoHS-compliant matte-tin plating, and moisture sensitivity level (MSL) 1 - suitable for standard reflow soldering without dry-pack requirements.
