Product details
Overview
MAX6716UTVHD3+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, and manual reset input - used to ensure reliable boot and brownout recovery in multivoltage embedded systems.
For engineers reviewing the MAX6716UTVHD3+T datasheet, MAX6716UTVHD3+T pinout, MAX6716UTVHD3+T application, or MAX6716UTVHD3+T equivalent, key selection criteria include guaranteed reset validity down to VCC1/VCC2 = 0.8V, 14µA typical supply current at 3.6V, immunity to short VCC transients, and compatibility with bidirectional µP reset I/O via series resistor.
Technical Context
The MAX6716UTVHD3+T implements dual independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a reset timeout timer with fixed 210ms (min) delay, and push-pull RST output referenced to VCC1. It guarantees correct reset logic state when either VCC1 or VCC2 ≥ 0.8V.
This variant lacks RSTIN, WDI, PFI/PFO, and RST2 - confirmed by Selector Guide and Pin Configuration tables - and includes internal 50kΩ MR pullup, 20ppm/°C reset threshold tempco, and 0.5% hysteresis referenced to VTH typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed falling threshold; ensures reset assertion before 5V rail collapse) |
| VCC2 Threshold | 3.075V (factory-trimmed falling threshold; matches common 3.3V I/O supply margin) |
| Reset Timeout | 210ms min (guaranteed minimum delay after all supplies recover; prevents premature release) |
| Supply Current | 14µA typ at 3.6V (ultra-low quiescent draw enables battery-backed or energy-sensitive designs) |
| Operating Temp | -40°C to +85°C (industrial-grade range suitable for telecom, industrial, and computing equipment) |
| Reset Output | Push-pull active-low RST (no external pullup required; drives high to ≥0.8×VCC1 when deasserted) |
| MR Input | Active-low with 50kΩ internal pullup to VCC1 (enables momentary switch interface without external components) |
Pinout & Package
Package: 6-pin SOT23-6, surface-mount, lead-free (+T suffix), footprint compatible with JEDEC MO-178AB.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; asserts low on VCC1/VCC2 undervoltage or MR low; drives high to ≥0.8×VCC1 when released |
| 2 | GND | Analog/digital ground reference; must be low-impedance connection for accurate threshold sensing |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1 (50kΩ); pulse width ≥1µs required to trigger reset |
| 4 | VCC2 | Secondary supply input (monitored at 3.075V); powers internal circuitry when > VCC1; sets RST2 reference if present (not implemented in this variant) |
| 5 | VCC1 | Primary supply input (monitored at 4.625V); powers device when > VCC2; reference for RST output high-level and MR pullup |
| 6 | NC | No connect; unused pin per MAX6716 pin mapping; must remain unconnected or grounded per design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed voltage monitoring | Simultaneous 4.625V (VCC1) and 3.075V (VCC2) thresholds eliminate external resistor dividers and calibration |
| Guaranteed reset validity down to 0.8V | Ensures deterministic reset behavior during deep brownout - critical for safe µP shutdown in power-loss scenarios |
| Push-pull RST output | Removes need for external pullup resistor, simplifying BOM and improving noise immunity on reset line |
| Manual reset with internal pullup | Enables direct connection of momentary switch to GND (no external R/C), reducing board space and component count |
| Immunity to short VCC transients | Rejects sub-20µs glitches below reset threshold - prevents spurious resets in electrically noisy environments |
Applications
| Industrial PLC Control | Telecom Line Card |
|---|---|
Use Scenario: Programmable logic controller operating across wide ambient temperature and input voltage fluctuations. IC Role / Device Role / Timing Role: Dual-rail supervisor ensuring synchronized reset of ARM Cortex-M7 core (VCC1 = 5V) and FPGA I/O bank (VCC2 = 3.3V) during brownout. Use Value: 210ms timeout prevents restart attempts before bulk capacitors fully discharge; 0.8V reset validity enables fail-safe shutdown before µP enters undefined state. |
Use Scenario: Carrier-grade Ethernet line card with hot-swap power modules and redundant 5V/3.3V rails. IC Role / Device Role / Timing Role: Primary supervisor verifying both primary DC-DC outputs before enabling SERDES and PHY initialization sequence. Use Value: Push-pull RST eliminates pullup conflicts with bidirectional µP reset pins; 14µA supply current minimizes standby loss in always-on management subsystems. |
| Medical Diagnostic Imaging | Network Attached Storage |
Use Scenario: Portable ultrasound system powered by Li-ion battery with regulated 5V and 3.3V supplies. IC Role / Device Role / Timing Role: System-level supervisor asserting reset on battery voltage sag below 4.625V (VCC1) or LDO dropout (VCC2 = 3.075V). Use Value: Factory-trimmed thresholds remove calibration overhead; 20ppm/°C tempco ensures stable trip points across -10°C to +50°C clinical operating range. |
Use Scenario: RAID controller board with multiple voltage domains (CPU core, memory, SATA PHY) and thermal throttling. IC Role / Device Role / Timing Role: Secondary supervisor validating auxiliary 5V standby and 3.3V I/O rails prior to main SoC boot sequence. Use Value: MR input enables hardware-initiated reset during firmware update failure; NC pin simplifies layout routing in dense PCB stackups. |
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 | Open-drain RST output; identical VTH1/VTH2 (4.625V/3.075V) and 210ms timeout | Requires external pullup resistor; suitable where reset line shares bus with other open-drain devices | Select when interoperability with I²C-style reset buses or level-shifting interfaces is required |
| TPS3808G33DBVR | Single-supply monitor (3.3V only); 200ms timeout; 2.5µA supply current; SOT23-6 | Monitors only one rail; no VCC2 input; lower quiescent current but no dual-rail coordination | Choose for cost-sensitive single-rail applications where VCC2 supervision is handled separately |
Compared with MAX6716UTVHD3+T, MAX6715UTLTD3+T offers identical voltage thresholds and timing but requires external pullup, while TPS3808G33DBVR reduces supply current by 82% but sacrifices dual-rail correlation - making MAX6716UTVHD3+T optimal for coordinated 5V/3.3V system integrity.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6716UTVHD3+T?
The MAX6716UTVHD3+T has factory-trimmed reset thresholds of 4.625V for VCC1 (primary supply) and 3.075V for VCC2 (secondary supply), as defined by the "TV" suffix per Maxim's Reset Voltage Threshold Suffix Guide. These values are guaranteed over -40°C to +85°C with ±1.5% tolerance and 20ppm/°C tempco, ensuring precise brownout detection without external calibration.
Does the MAX6716UTVHD3+T support watchdog or power-fail functionality?
No, the MAX6716UTVHD3+T does not include watchdog input (WDI), power-fail input/output (PFI/PFO), or adjustable RSTIN functionality. Per the Selector Guide and Pin Configuration tables, it is a dual-voltage-only variant with push-pull RST, MR, VCC1, VCC2, GND, and NC - confirming absence of WDI, PFI, RSTIN, and RST2 terminals.
What is the function of Pin 6 (NC) on the MAX6716UTVHD3+T?
Pin 6 on the MAX6716UTVHD3+T is designated NC (No Connect) and must remain unconnected per Maxim's datasheet guidance. This pin is unused in the MAX6716 variant and is not bonded internally; grounding or routing it may cause unintended behavior or violate ESD protection schemes.
How does the manual reset (MR) input behave on the MAX6716UTVHD3+T?
The MR input on MAX6716UTVHD3+T is active-low with an internal 50kΩ pullup to VCC1. Pulling MR to GND for ≥1µs asserts RST low immediately and holds it for the full 210ms timeout after MR returns high. If left floating, MR remains high due to the internal pullup, allowing normal voltage-monitoring operation without external components.
Is the MAX6716UTVHD3+T compatible with bidirectional microprocessor reset pins?
Yes, the MAX6716UTVHD3+T's push-pull RST output can interface with bidirectional µP reset pins using a 4.7kΩ series resistor (per Figure 4 in the datasheet) to prevent logic contention. This configuration allows the µP to drive reset low for self-test or debug while retaining autonomous brownout detection and assertion by the MAX6716UTVHD3+T.
