Product details
Overview
MAX6715UTRVD3-T from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (1.575V threshold) and VCC2 (0.788V threshold) with 210ms minimum reset timeout, push-pull active-low RST output, and manual reset input - used to ensure reliable power-on reset and brownout recovery in battery-powered embedded systems.
For engineers reviewing the MAX6715UTRVD3-T datasheet, MAX6715UTRVD3-T pinout, MAX6715UTRVD3-T application, or MAX6715UTRVD3-T equivalent, key selection factors include guaranteed reset validity down to VCC = 0.8V, 14µA typical supply current at 3.6V, immunity to short VCC transients, and factory-trimmed dual-threshold supervision without external resistors.
Technical Context
The MAX6715UTRVD3-T implements two independent voltage comparators with internal reference trimming, asserting reset when either VCC1 falls below 1.575V (±2.5%) or VCC2 drops below 0.788V (±2.5%), maintaining reset for ≥210ms after both supplies recover. Its push-pull RST output is referenced to VCC1 and sinks up to 3.2mA at 4.5V.
It features an internal 50kΩ pullup on MR, supports 1µs minimum manual reset pulse width, and guarantees correct reset logic state as long as VCC1 or VCC2 remains ≥0.8V - enabling robust operation during deep brownout conditions common in portable equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 1.575V (typ), ±2.5% tolerance - sets precise brownout detection for primary 1.8V/2.5V rails |
| VCC2 Threshold | 0.788V (typ), ±2.5% tolerance - enables reliable monitoring of secondary 0.9V–1.2V core supplies |
| Reset Timeout | 210ms (min) - ensures sufficient hold time for slow-starting processors and peripherals |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent drain in always-on battery backup paths |
| Operating Temp | -40°C to +85°C - qualified for industrial and extended-temperature embedded applications |
| Reset Output | Push-pull, active-low, VCC1-referenced - eliminates need for external pullup and simplifies µP interface |
| MR Input | Internal 50kΩ pullup to VCC1 - allows direct switch-to-GND connection without external components |
Pinout & Package
MAX6715UTRVD3-T is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), surface-mount, RoHS-compliant, with gull-wing leads and thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; asserts low on fault and holds for 210ms minimum |
| 2 | GND | Analog/digital ground reference for all internal comparators and logic |
| 3 | MR | Active-low manual reset input with internal 50kΩ pullup to VCC1; 1µs minimum pulse width required |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal VCC2 comparator and sets VCC2 threshold reference |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers device core and sets VCC1 threshold reference |
| 6 | NC | No connect - internally unconnected; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | Eliminates external resistor networks for VCC1/VCC2 monitoring - reduces BOM count and layout area |
| Guaranteed reset validity to 0.8V | Ensures deterministic reset assertion even during severe brownout, preventing processor lockup |
| 14µA typical supply current | Extends battery life in always-on supervisory paths - critical for coin-cell or energy-harvesting systems |
| Push-pull RST output | Drives µP reset pin directly without pullup resistor - simplifies schematic and improves noise immunity |
| Immunity to short VCC transients | Rejects <20µs glitches below threshold - avoids spurious resets during switching noise or load dumps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G12DBVR | Single-supply monitor (VDD only); 1.2V fixed threshold; 200ms timeout; open-drain RST | Lacks VCC2 monitoring capability - requires second IC or external divider for dual-rail systems | Select when only primary rail supervision is needed and board space permits external pullup |
| ADM6710LAKSZ-REEL7 | Triple-supply monitor; 1.6V/2.5V/3.3V thresholds; 200ms timeout; push-pull RST; -40°C to +125°C | Higher temperature rating and triple monitoring - over-spec'd for dual-rail, cost-sensitive designs | Choose for automotive-adjacent industrial use cases requiring extended temp range |
Compared with TPS3808G12DBVR and ADM6710LAKSZ-REEL7, MAX6715UTRVD3-T delivers optimized dual-rail supervision in minimal SOT23-6 footprint with factory-trimmed thresholds, eliminating calibration effort while maintaining 14µA supply current and 0.8V reset guarantee - ideal for space-constrained, battery-operated systems.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6715UTRVD3-T?
The MAX6715UTRVD3-T has a factory-trimmed VCC1 reset threshold of 1.575V (typical), with ±2.5% tolerance over temperature. This value is fixed by the "RV" suffix per Maxim's Reset Voltage Threshold Suffix Guide and does not require external resistor programming. The threshold remains stable across the full -40°C to +85°C operating range, enabling precise brownout detection for 1.8V logic rails without calibration.
Does MAX6715UTRVD3-T support monitoring a third voltage rail?
No, MAX6715UTRVD3-T is a dual-voltage supervisor and does not include RSTIN or PFI inputs. It monitors only VCC1 and VCC2. For triple-voltage supervision, consider MAX6719UTRVD3-T (with RSTIN) or MAX6728KA-RVD3-T (with PFI/PFO). The MAX6715UTRVD3-T pinout omits RSTIN, WDI, PFI, and PFO terminals - confirmed by its Selector Guide entry showing no "√" under Adjustable Input or Power-Fail columns.
What is the function of Pin 6 on MAX6715UTRVD3-T?
Pin 6 on MAX6715UTRVD3-T is NC (No Connect) - internally unconnected and not bonded. It must be left floating or tied to GND per PCB layout best practices to avoid parasitic coupling. This differs from other variants like MAX6729 (which uses Pin 6 for PFO) and is confirmed in the Pin Description table where Pin 6 maps only to VCC1 for MAX6715/MAX6716, with no alternate function listed.
How does the manual reset (MR) input behave on MAX6715UTRVD3-T?
The MR input on MAX6715UTRVD3-T is active-low with an internal 50kΩ pullup to VCC1. Pulling MR to GND for ≥1µs forces RST low for the full 210ms timeout period, regardless of VCC status. When released, reset remains asserted for the timeout duration. No external components are needed - a simple SPST switch from MR to GND suffices. Glitch rejection is 100ns, ensuring noise immunity in electrically noisy environments.
Is MAX6715UTRVD3-T compatible with 1.2V VCC2 supplies?
Yes, MAX6715UTRVD3-T supports VCC2 down to 0.9V per datasheet specifications, and its 0.788V threshold is valid for monitoring 1.2V rails with adequate margin. The device guarantees correct reset logic state as long as VCC1 or VCC2 remains ≥0.8V - making it suitable for modern ultra-low-voltage systems using 1.2V or 1.1V secondary supplies. Operation is fully specified from -40°C to +85°C with no derating required.
