Product details
Overview
MAX6716UTTGD3 from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 6-pin SOT23 package, monitoring VCC1 (4.625V threshold) and VCC2 (3.075V threshold) with 210ms reset timeout, push-pull active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in telecom power sequencing and industrial CPU reset management.
For engineers reviewing the MAX6716UTTGD3 datasheet, MAX6716UTTGD3 pinout, MAX6716UTTGD3 application, or MAX6716UTTGD3 equivalent, key selection criteria include dual-supply threshold accuracy, 210ms minimum timeout, push-pull RST drive capability, immunity to sub-100ns VCC transients, and operation across –40°C to +125°C.
Technical Context
The MAX6716UTTGD3 implements two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), each referenced to internal bandgap references with ±1.5% tolerance over temperature. Its reset logic asserts RST low when either supply falls below its threshold and holds for a guaranteed 210ms (min) after both supplies recover.
This device integrates no watchdog, manual-reset, or power-fail functions - confirmed by suffix "D3" (timeout only) and absence of WDI, MR, PFI/PFO pins in its 6-pin SOT23 configuration. It uses push-pull RST output referenced to VCC1, eliminating external pull-up requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (typ), ±1.5% over –40°C to +125°C - ensures reliable reset assertion during 5V rail brownout |
| VCC2 Threshold | 3.075V (typ), ±1.5% over –40°C to +125°C - matches common 3.3V I/O supply monitoring |
| Reset Timeout | 210ms (min), fixed via part number suffix - provides sufficient hold time for CPU boot initialization |
| Supply Current | 14µA (typ) at 3.6V - enables ultra-low-power operation in battery-backed systems |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive and industrial control environments |
| Reset Validity | Guaranteed down to VCC1 or VCC2 = 0.8V - supports valid reset assertion during deep brownout conditions |
| Output Type | Push-pull active-low RST - drives directly into µP reset pin without external pull-up resistor |
Pinout & Package
MAX6716UTTGD3 is housed in a 6-pin SOT23 package (2.9mm × 1.6mm × 1.1mm), with thermal pad omitted. Pin 1 is marked via dot; pin numbering follows standard SOT23 convention (counterclockwise from mark).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST) | Active-low reset output | Push-pull driver referenced to VCC1; sinks 3.2mA at VCC1 ≥ 4.5V; no external pull-up needed |
| 2 (GND) | Ground reference | Common return for all internal circuitry and reset output; must be low-impedance connection |
| 3 (MR) | Manual-reset input | Active-low CMOS-compatible input with 50kΩ internal pullup to VCC1; resets on falling edge |
| 4 (VCC2) | Secondary supply input | Powers internal VCC2 comparator and sets VTH2 = 3.075V; valid from 0.8V to 5.5V |
| 5 (VCC1) | Primary supply input | Powers device core and sets VTH1 = 4.625V; valid from 0.8V to 5.5V; defines RST output reference |
| 6 (NC) | No connect | Internally unconnected; must remain floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators and hysteresis |
| Factory-trimmed precision thresholds | ±1.5% total accuracy over full temperature range eliminates need for external calibration |
| Fixed 210ms reset timeout | Guaranteed minimum delay prevents premature release during supply recovery transients |
| Push-pull RST output | Drives µP reset pin directly without pull-up resistor, reducing BOM count and PCB area |
| Ultra-low quiescent current | 14µA typical at 3.6V enables >10-year battery life in always-on monitoring applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | 3.3V fixed VDD threshold only; single-supply monitor; 200ms timeout; open-drain RST | Lacks VCC2 monitoring capability; requires external pull-up; not suitable for dual-rail validation | Select only when monitoring one supply rail and board space permits pull-up resistor |
| ADM6716ARTZ-4625-R7 | Same 4.625V/3.075V thresholds and 210ms timeout; push-pull RST; but 5-pin SOT23 with no MR pin | Omits manual-reset functionality; smaller footprint but loses field-service reset capability | Choose when MR is unused and PCB area is constrained; verify MR omission acceptable for system test flow |
Compared with TPS3808G33DBVR and ADM6716ARTZ-4625-R7, MAX6716UTTGD3 uniquely combines dual-threshold precision, integrated MR, and push-pull RST in a 6-pin SOT23 - delivering full feature parity without layout compromise or external components.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on MAX6716UTTGD3?
The MAX6716UTTGD3 has factory-trimmed reset thresholds of 4.625V (VCC1) and 3.075V (VCC2), with ±1.5% total accuracy over –40°C to +125°C. These values are defined by the "TT" suffix per Maxim's Reset Voltage Threshold Suffix Guide and confirmed in the Electrical Characteristics table of the official datasheet.
Does MAX6716UTTGD3 include a watchdog timer function?
No, MAX6716UTTGD3 does not include a watchdog timer. The "D3" suffix denotes a 210ms reset timeout only, and the device lacks WDI pin functionality. Watchdog capability is present only in variants with "W" or "WD" in the part number (e.g., MAX6721A–MAX6729A), which have dedicated WDI pins and dual-mode timeout architecture.
Can MAX6716UTTGD3 monitor a third voltage using RSTIN?
No, MAX6716UTTGD3 does not support RSTIN-based auxiliary voltage monitoring. The RSTIN pin is absent in this variant - only MAX6719A/MAX6720A and MAX6723A–MAX6727A include RSTIN. MAX6716UTTGD3 is strictly a dual-supply supervisor with VCC1 and VCC2 inputs only.
What is the purpose of the NC pin on MAX6716UTTGD3?
Pin 6 of MAX6716UTTGD3 is designated NC (no connect) - it is internally unconnected and serves no functional role. Per Maxim's layout guidance, it may be left floating or tied to GND to improve mechanical stability and reduce noise coupling; it must never be connected to VCC or signal lines.
How does the push-pull RST output of MAX6716UTTGD3 differ from open-drain alternatives?
The push-pull RST output of MAX6716UTTGD3 actively drives both high (to VCC1) and low (to GND), eliminating the need for an external pull-up resistor. This reduces BOM cost and PCB area versus open-drain variants like MAX6715A, while ensuring faster rise/fall times and stronger drive capability - especially critical for driving long traces or multiple loads.
