Product details
Overview
MAX6716UTYDD3-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (4.625V threshold) and VCC2 (3.075V threshold) with 210ms minimum reset timeout, push-pull active-low RST output, manual reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in telecom power sequencing and server board management.
For engineers reviewing the MAX6716UTYDD3-T datasheet, MAX6716UTYDD3-T pinout, MAX6716UTYDD3-T application, or MAX6716UTYDD3-T equivalent, key selection factors 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 systems.
Technical Context
The MAX6716UTYDD3-T integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a 210ms reset timeout timer, and push-pull RST output referenced to VCC1. It asserts reset when either monitored supply falls below its threshold and holds reset for ≥210ms after both supplies recover.
No watchdog, RSTIN, PFI, or PFO functions are present - confirmed by Selector Guide and Ordering Information: MAX6716 supports only dual-voltage monitoring, manual reset (MR), and push-pull RST. Its internal 50kΩ MR pullup and 200ns MR-to-reset delay enable direct switch interfacing without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed, ±1.5% over -40°C to +85°C) - sets precise brownout detection for 5V or 4.8V primary rails |
| VCC2 Threshold | 3.075V (factory-trimmed, ±1.5% over -40°C to +85°C) - matches common 3.3V secondary supply with margin |
| Reset Timeout | 210ms (minimum) - ensures sufficient hold time for FPGA configuration or DRAM initialization sequences |
| Supply Current | 14µA typical at 3.6V - enables always-on supervision in battery-backed systems without measurable drain |
| Reset Validity | Down to VCC1 or VCC2 = 0.8V - guarantees correct logic state during deep brownout, critical for safe shutdown |
| MR Input | Active-low with 50kΩ internal pullup to VCC1 - allows momentary switch connection without external resistor |
| Output Type | Push-pull active-low RST referenced to VCC1 - eliminates need for external pullup and drives 3.2mA load directly |
Pinout & Package
MAX6716UTYDD3-T uses a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with thermal pad option. Pin 1 marked via dot; pins arranged linearly with GND at Pin 2, VCC2 at Pin 4, VCC1 at Pin 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; sinks 3.2mA at VCC1 ≥ 4.5V, VOL ≤ 0.4V |
| 2 | GND | Ground reference for all internal comparators, timer, and output driver; must be low-impedance |
| 3 | MR | Active-low manual reset input with 50kΩ internal pullup to VCC1; 200ns delay to RST assertion |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal VTH2 comparator and enables VCC2 monitoring |
| 5 | NC | No connect - internally unconnected; must remain floating or tied to GND per layout guidelines |
| 6 | VCC1 | Primary supply input (1.8V–5.0V range); powers device core, VTH1 comparator, and RST output driver |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators avoids single-point failure |
| Guaranteed reset validity to 0.8V | Ensures deterministic reset assertion even during severe brownout - no external undervoltage lockout needed |
| Push-pull RST output | Drives loads directly without pullup resistor; compatible with 1.8V–5V µP reset inputs and reduces BOM count |
| Low-glitch immunity | Immune to VCC transients <20µs (at 100mV overdrive), preventing spurious resets in noisy power environments |
| Integrated MR pullup | 50kΩ internal VCC1-referenced pullup eliminates discrete resistor, simplifies PCB layout and reduces footprint |
Applications
| Telecom Line Card Power Sequencing | Industrial PLC CPU Board |
|---|---|
Use Scenario: Dual-rail (5V/3.3V) power-up sequencing on high-density line cards with strict timing requirements. IC Role / Device Role / Timing Role: Supervises VCC1 (5V analog supply) and VCC2 (3.3V digital I/O) to assert synchronized reset until both rails stabilize above thresholds. Use Value: Prevents metastability in SerDes PHYs and FPGAs by enforcing 210ms minimum reset hold time post-power-up. |
Use Scenario: Embedded controller board operating in harsh industrial environments with fluctuating 24V DC input. IC Role / Device Role / Timing Role: Monitors regulated 5V (VCC1) and 3.3V (VCC2) rails derived from switching converter; triggers reset on undervoltage. Use Value: Enables fail-safe shutdown before CPU corruption occurs, leveraging 0.8V reset validity during brownout recovery. |
| Server Baseboard Management | Medical Diagnostic Imaging Module |
Use Scenario: BMC (Baseboard Management Controller) power domain supervision in 1U rack servers. IC Role / Device Role / Timing Role: Provides dedicated reset signaling for ARM-based BMC SoC using push-pull RST driven from 3.3V rail. Use Value: Eliminates external level-shifter or pullup, reducing signal path delay and improving reset timing predictability. |
Use Scenario: Real-time image processing module requiring guaranteed boot integrity after AC power interruption. IC Role / Device Role / Timing Role: Supervises 1.8V FPGA core and 3.3V ADC interface supplies; asserts reset if either drops below threshold. Use Value: Ensures deterministic reinitialization of safety-critical imaging pipeline, meeting IEC 62304 Class C requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316US31D3-T | Single-supply (3.08V threshold), same 210ms timeout, SOT23-5 package, open-drain RST | Lacks VCC2 monitoring; requires external pullup; suitable only for single-rail systems | Select when only one supply needs supervision and board space is constrained (5-pin vs. 6-pin) |
| TPS3808G33DBVR | Single-supply (3.3V threshold), 200ms timeout, SOT23-6, open-drain RST, higher 25µA ICC | No dual-monitoring capability; no MR input; designed for TI ecosystem integration | Choose for cost-sensitive designs where 3.3V-only supervision suffices and TI supply chain preference applies |
Compared with MAX6716UTYDD3-T, MAX6316US31D3-T reduces functionality to single-rail supervision but saves board area, while TPS3808G33DBVR trades dual monitoring and MR support for broader TI design tool compatibility and slightly faster timeout - neither offers pin compatibility or identical feature set.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6716UTYDD3-T?
The MAX6716UTYDD3-T has factory-trimmed reset thresholds of 4.625V for VCC1 and 3.075V for VCC2, with ±1.5% tolerance over the full -40°C to +85°C temperature range. These values are fixed by the "YT" suffix per Maxim's Reset Voltage Threshold Suffix Guide and do not require external resistor programming.
Does the MAX6716UTYDD3-T support watchdog timer or power-fail monitoring functions?
No, the MAX6716UTYDD3-T does not include watchdog timer (WDI), power-fail input (PFI), or power-fail output (PFO) functionality. Per Maxim's Selector Guide, MAX6716 is designated for dual-voltage supervision only with manual reset (MR) and push-pull RST - features like WDI and PFI appear only in MAX6721 and higher variants.
What is the reset timeout period for the MAX6716UTYDD3-T, and is it adjustable?
The MAX6716UTYDD3-T has a fixed minimum reset timeout period of 210ms, indicated by the "D3" suffix in the part number. This value is factory-set and not adjustable via external components or configuration pins - it is guaranteed over temperature and supply voltage variations per the Electrical Characteristics table.
Can the MAX6716UTYDD3-T operate with VCC1 = 1.8V and VCC2 = 1.2V?
Yes, the MAX6716UTYDD3-T operates with VCC1 as low as 1.8V and VCC2 as low as 0.9V per datasheet specifications. However, its factory-trimmed thresholds (4.625V/3.075V) are optimized for higher rails; using it at 1.8V/1.2V would result in permanent reset assertion since both supplies fall far below their thresholds.
Is the MAX6716UTYDD3-T pin-compatible with other devices in the MAX6715–MAX6729 family?
The MAX6716UTYDD3-T shares the same 6-pin SOT23-6 package and pinout (RST, GND, MR, VCC2, NC, VCC1) with MAX6715, MAX6719, MAX6721, and MAX6723 variants. However, functional differences (e.g., presence of RSTIN, WDI, or PFI) mean that direct substitution may cause system malfunction unless verified against the Selector Guide.
