Product details
Overview
MAX6716AUTTGD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 6-pin SOT23 package, monitoring VCC1 (4.625V factory-trimmed threshold) and VCC2 (3.075V threshold) with 210ms minimum reset timeout, push-pull active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V. It supports telecom power systems requiring reliable brownout detection and orderly reset sequencing.
For engineers reviewing the MAX6716AUTTGD3+ datasheet, MAX6716AUTTGD3+ pinout, MAX6716AUTTGD3+ application, or MAX6716AUTTGD3+ equivalent, this page delivers verified electrical parameters, exact pin functions per variant, real-world multivoltage supervision use cases, and two confirmed alternative parts with documented functional differences.
Technical Context
The MAX6716AUTTGD3+ implements dual independent voltage comparators with internal 4.625V and 3.075V thresholds referenced to VCC1 and VCC2 respectively, each feeding a shared reset timeout timer. Its push-pull RST output is referenced to VCC1 and asserts low when either supply falls below its threshold or MR is pulled low.
It features no watchdog, manual-reset input (MR) with 50kΩ internal pullup to VCC1, and immunity to VCC transients ≤20µs at 100mV overdrive. The device operates across -40°C to +125°C and draws only 10µA typical supply current at 3.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (factory-trimmed, ±125mV tolerance), ensures reliable detection of 5V rail brownout before system instability |
| VCC2 Reset Threshold | 3.075V (factory-trimmed, ±75mV tolerance), matches standard 3.3V I/O supply for coordinated reset assertion |
| Reset Timeout Period | 210ms minimum (D3 suffix), provides sufficient hold time for processor initialization and peripheral stabilization |
| Supply Current | 10µA typical at 3.6V, enables ultra-low-power operation in battery-backed or energy-sensitive systems |
| Operating Temperature | -40°C to +125°C, qualified for under-hood automotive, industrial control, and telecom base station environments |
| Reset Output Type | Push-pull active-low RST, eliminates need for external pullup and ensures fast, rail-referenced logic levels |
| Minimum Valid VCC | 0.8V on VCC1 or VCC2, guarantees correct reset state during deep brownout conditions prior to full power loss |
Pinout & Package
Package: 6-pin SOT23 (lead-free/RoHS-compliant, tape-and-reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-low reset output | Push-pull driver referenced to VCC1; asserts low on VCC1/VCC2 undervoltage, MR low, or timeout expiration |
| 2 - GND | Ground reference | Common return path for all internal comparators, timers, and output drivers; must be low-impedance |
| 3 - MR | Manual-reset input | Active-low input with 50kΩ internal pullup to VCC1; forces reset when pulled ≤0.3×VCC1 for ≥1µs |
| 4 - VCC2 | Secondary supply input | Powers internal circuitry when VCC2 > VCC1; monitored by 3.075V comparator for 3.3V rail supervision |
| 5 - VCC1 | Primary supply input | Powers internal circuitry when VCC1 > VCC2; monitored by 4.625V comparator for 5V rail supervision |
| 6 - NC | No-connect terminal | Internally unconnected; must remain floating or tied to GND per layout best practices for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | 4.625V on VCC1 and 3.075V on VCC2 enable precise, zero-calibration supervision of 5V/3.3V dual-rail systems |
| 210ms minimum reset timeout | Ensures processor and peripherals fully initialize before release, preventing race conditions in complex boot sequences |
| Push-pull RST output | Eliminates external pullup resistor, reduces BOM count, and improves rise/fall time vs. open-drain alternatives |
| 0.8V minimum operating voltage | Guarantees valid reset assertion during deep brownout, supporting fail-safe shutdown before complete power collapse |
| 10µA typical supply current | Minimizes quiescent load on backup supplies and extends battery life in portable or always-on monitoring applications |
Applications
| Telecom Power Management | Industrial PLC I/O Modules |
|---|---|
Use Scenario: Monitoring primary 5V and secondary 3.3V rails in remote radio unit power supplies where brownout resilience is critical. IC Role / Device Role / Timing Role: Dual-voltage supervisor asserting synchronized reset to FPGA and baseband processor upon any rail failure. Use Value: Prevents corrupted configuration writes during partial power loss, reducing field failures caused by inconsistent power sequencing. |
Use Scenario: Supervising isolated 5V logic and 3.3V sensor interface supplies in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Providing deterministic reset timing and manual reset capability for firmware updates and fault recovery. Use Value: Enables safe hot-swap of I/O modules without system-wide reboot, improving uptime in continuous-process automation. |
| Automotive Infotainment Head Units | Network Equipment Line Cards |
Use Scenario: Ensuring clean startup and brownout recovery for SoC-based head units powered from vehicle battery (5V) and regulated 3.3V domain. IC Role / Device Role / Timing Role: Asserting reset until both rails stabilize above 4.625V and 3.075V, then holding for 210ms before release. Use Value: Eliminates boot hangs caused by slow-rising 3.3V rail relative to 5V, meeting AEC-Q100 reliability requirements. |
Use Scenario: Supervising redundant 5V and 3.3V DC-DC outputs on high-density line cards where thermal derating affects rail stability. IC Role / Device Role / Timing Role: Detecting simultaneous or staggered rail collapse and triggering controlled ASIC reset via push-pull RST. Use Value: Avoids metastability in SerDes links by ensuring all voltage domains meet timing margins before clock enable. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AUTLTD3+ | Open-drain RST output (vs. push-pull), identical thresholds and timeout | Requires external pullup resistor; suitable where level-shifting or wired-OR reset bus is needed | Select when interfacing to bidirectional µP reset pins or multi-source reset arbitration networks |
| TPS3808G33DBVR | Single-supply monitor (3.3V only), 200ms timeout, 1.8µA quiescent current | Lacks VCC2 monitoring; requires separate IC for 5V rail supervision | Choose only for single-rail systems; not a drop-in replacement due to missing dual-threshold architecture |
Compared with MAX6716AUTTGD3+, MAX6715AUTLTD3+ offers identical supervision logic but mandates external biasing, while TPS3808G33DBVR reduces power consumption at the cost of losing dual-voltage capability-making it unsuitable for systems requiring coordinated 5V/3.3V reset sequencing.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6716AUTTGD3+?
The MAX6716AUTTGD3+ has a factory-trimmed VCC1 reset threshold of 4.625V, with a tolerance of ±125mV (4.500V to 4.750V). This value is fixed by the "TG" suffix per Maxim's Reset Voltage Threshold Suffix Guide and applies across the full -40°C to +125°C operating range with 20ppm/°C tempco.
Does the MAX6716AUTTGD3+ include a watchdog timer function?
No, the MAX6716AUTTGD3+ does not include a watchdog timer. Its ordering code lacks the "W" or "WD" designation found in variants like MAX6721A–MAX6729A. The MAX6716AUTTGD3+ provides only dual-voltage monitoring, manual reset input, and fixed 210ms reset timeout.
What is the function of Pin 6 on the MAX6716AUTTGD3+?
Pin 6 on the MAX6716AUTTGD3+ is a no-connect (NC) terminal. It is internally unconnected and must remain floating or be tied to GND per PCB layout guidelines to minimize noise coupling. It is not used for reset, monitoring, or control functions in this variant.
Can the MAX6716AUTTGD3+ monitor a third voltage rail?
No, the MAX6716AUTTGD3+ is a dual-supply supervisor only. It monitors VCC1 and VCC2 exclusively. Third-rail monitoring requires variants with RSTIN input (e.g., MAX6719A/MAX6720A), which the MAX6716AUTTGD3+ does not implement per its pinout and functional diagram.
What is the maximum supply voltage the MAX6716AUTTGD3+ can tolerate on VCC1 or VCC2?
The MAX6716AUTTGD3+ supports absolute maximum supply voltages of -0.3V to +6V on VCC1 and VCC2. However, functional operation is specified from 0.8V to 5.5V. Exceeding 5.5V risks permanent damage, and operation above 5.5V is outside guaranteed specifications.
