Product details
Overview
MAX6716UTSVD3-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 embedded system brownout protection.
For engineers reviewing the MAX6716UTSVD3-T datasheet, MAX6716UTSVD3-T pinout, MAX6716UTSVD3-T application, or MAX6716UTSVD3-T equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temperature), ultra-low 14µA typical supply current at 3.6V, immunity to sub-20µs VCC transients, and push-pull reset drive capability without external pullup.
Technical Context
The MAX6716UTSVD3-T implements independent voltage comparators for primary (VCC1) and secondary (VCC2) supplies, each with factory-trimmed thresholds (4.625V and 3.075V respectively), hysteresis of 0.5% of VTH, and tempco of 20ppm/°C. Reset assertion occurs on first fault detection and remains asserted for ≥210ms after all monitored voltages exceed thresholds.
It features a push-pull RST output referenced to VCC1, internal 50kΩ MR pullup, and no watchdog or RSTIN/PFI functionality - confirmed by Selector Guide and Ordering Information showing MAX6716 as dual-monitor, push-pull, manual-reset-only variant with no WDI, RSTIN, or PFI pins enabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed falling threshold; ±1.5% over -40°C to +85°C) |
| VCC2 Threshold | 3.075V (factory-trimmed falling threshold; ±1.5% over -40°C to +85°C) |
| Reset Timeout | 210ms min (guaranteed minimum duration RST stays low after recovery) |
| Supply Current | 14µA typ at 3.6V (enables battery-backed systems with multi-year standby life) |
| Operating Temp | -40°C to +85°C (industrial-grade thermal range for telecom and embedded use) |
| Reset Output Type | Push-pull active-low (drives high/low directly; no external pullup required) |
| VCC Validity Limit | Reset logic valid down to VCC1 or VCC2 = 0.8V (ensures reliable assertion during deep brownout) |
Pinout & Package
MAX6716UTSVD3-T is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with gull-wing leads and standard JEDEC MO-178AC footprint.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; sinks 3.2mA at VCC1 ≥ 4.5V; drives high to 0.8×VCC1 |
| 2 | GND | Ground reference for all internal comparators, timers, and output drivers |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1 (50kΩ); accepts TTL/CMOS levels |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal VCC2 comparator and sets RST2 reference if present (not used in MAX6716) |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers device core, sets RST output reference, and enables VCC1 comparator |
| 6 | NC | No connect (unused pin per MAX6716 pin mapping; must be left floating or grounded) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators and hysteresis |
| Guaranteed reset validity at low VCC | Outputs remain logically valid even when VCC1 or VCC2 drops to 0.8V - critical for graceful shutdown |
| Push-pull RST output | Eliminates need for external pullup resistor; drives full rail-to-rail with 3.2mA sink capability |
| Immunity to short VCC transients | Rejects negative-going glitches <20µs (at 100mV overdrive), preventing spurious resets in noisy environments |
| Low quiescent current | 14µA typical at 3.6V enables >10-year battery life in always-on monitoring applications |
Applications
| Telecom Power Sequencing | Industrial PLC I/O Module |
|---|---|
|
Use Scenario: Sequencing startup of dual-rail FPGA core (1.2V) and I/O (3.3V) supplies in base station radio units. IC Role / Device Role / Timing Role: Dual-threshold supervisor ensures 3.3V rail stabilizes before releasing FPGA reset, preventing configuration corruption. Use Value: Factory-trimmed 4.625V/3.075V thresholds match common 3.3V LDO tolerances; 210ms timeout accommodates slow-start DC/DC converters. |
Use Scenario: Monitoring 24V field power and 5V logic supply in programmable logic controller backplane. IC Role / Device Role / Timing Role: Asserts system reset if either supply sags below specification during motor switching transients. Use Value: 0.8V VCC validity limit ensures reset remains asserted until both rails recover fully - avoids partial initialization faults. |
| Medical Diagnostic Handheld | Automotive Infotainment MCU |
|
Use Scenario: Brownout protection for ARM Cortex-M7 running on Li-ion (3.0–4.2V) and buck-converted 1.8V core rails. IC Role / Device Role / Timing Role: Supervises main battery voltage and regulated core supply; triggers controlled firmware reboot on undervoltage. Use Value: 14µA supply current extends battery runtime; push-pull RST eliminates BOM cost of external pullup resistor. |
Use Scenario: Reset coordination between infotainment SoC and CAN transceiver during vehicle ignition cycling. IC Role / Device Role / Timing Role: Monitors 5V USB-C PD rail and 1.1V SoC core supply; holds reset until both meet spec post-cold crank. Use Value: Immunity to 20µs VCC dips prevents false resets during alternator load dump events. |
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 (requires external pullup); identical thresholds and timeout | Suitable where reset line is shared with other open-drain devices (e.g., I²C bus reset) | Select when system-level reset bus uses wired-AND topology and external pullup already exists |
| TLV809E33DBZR | Single-supply monitor (3.3V only); no VCC2 input; SOT23-3 package; 200ms timeout | Limited to single-rail systems; lacks dual-monitoring capability and manual reset | Choose only for cost-sensitive, single-voltage designs where VCC2 monitoring is unnecessary |
Compared with MAX6716UTSVD3-T, MAX6715UTLTD3-T offers identical supervision accuracy and timing but requires external pullup due to open-drain RST, while TLV809E33DBZR reduces footprint and cost at the expense of losing VCC2 monitoring, MR input, and push-pull drive - making it unsuitable for true dual-rail coordination.

FAQ
What are the exact reset threshold voltages for MAX6716UTSVD3-T?
The MAX6716UTSVD3-T has factory-trimmed reset thresholds of 4.625V for VCC1 (primary supply) and 3.075V for VCC2 (secondary supply), with ±1.5% tolerance over the full -40°C to +85°C operating range. These values are fixed by the "TS" suffix per Maxim's Reset Voltage Threshold Suffix Guide and do not require external resistor programming.
Does MAX6716UTSVD3-T include watchdog or power-fail functionality?
No, MAX6716UTSVD3-T does not include watchdog timer (WDI), power-fail input (PFI), or adjustable RSTIN functionality. Per Maxim's Selector Guide, MAX6716 is a dual-monitor, push-pull RST, manual-reset-only variant - confirmed by its pinout (no WDI, PFI, or RSTIN pins) and absence of related electrical specs in its datasheet section.
What is the function of Pin 6 on MAX6716UTSVD3-T?
Pin 6 on MAX6716UTSVD3-T is a no-connect (NC) terminal. It is unused in this variant and must be left floating or tied to GND - it is not bonded internally and serves no electrical function. This is consistent with the MAX6716's 6-pin SOT23-6 pin mapping shown in the official datasheet Pin Description table.
Can MAX6716UTSVD3-T operate with VCC1 = 1.8V and VCC2 = 1.2V?
Yes, MAX6716UTSVD3-T supports VCC1 as low as 1.8V and VCC2 as low as 0.9V per datasheet specifications. However, its factory-set thresholds (4.625V/3.075V) exceed those rails - meaning it will assert reset continuously. It is intended for higher-voltage dual-rail systems (e.g., 5V/3.3V or 3.3V/2.5V), not sub-3V applications.
What is the maximum sink current capability of the RST output on MAX6716UTSVD3-T?
The push-pull RST output on MAX6716UTSVD3-T can sink up to 3.2mA when VCC1 ≥ 4.5V, with VOL ≤ 0.4V under that condition. At lower VCC1 (≥2.7V), it sinks 1.2mA with VOL ≤ 0.3V. This eliminates need for external pullup and supports direct interfacing with most µP reset inputs.
