Product details
Overview
The MAX6715AUTRVD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in 6-pin SOT23 package, monitoring VCC1 (1.575V factory-trimmed threshold) and VCC2 (0.788V factory-trimmed threshold) with 210ms minimum 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 embedded controllers.
For engineers reviewing the MAX6715AUTRVD3+ datasheet, MAX6715AUTRVD3+ pinout, MAX6715AUTRVD3+ application, or MAX6715AUTRVD3+ equivalent, key selection criteria include dual-supply threshold accuracy, 210ms reset hold time, push-pull RST drive capability, immunity to sub-20µs VCC transients, and operation across –40°C to +125°C.
Technical Context
This device implements two independent voltage comparators with internal hysteresis (0.5% of VTH), a precision 210ms reset timeout timer, and a push-pull RST output referenced to VCC1. It requires no external components for basic dual-supply monitoring and asserts reset when either VCC1 falls below 1.575V or VCC2 drops below 0.788V.
The MAX6715AUTRVD3+ lacks RSTIN, WDI, PFI, PFO, and MR pins - confirmed by its "D" suffix in the Selector Guide and absence in its specific pin configuration. Its fixed thresholds and 210ms timeout are set at factory via part number coding (TRVD3), eliminating configuration overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 1.575V (typ), factory-trimmed - ensures reliable reset assertion for 1.6V/1.8V core supplies during brownout |
| VCC2 Threshold | 0.788V (typ), factory-trimmed - supports monitoring of sub-1V I/O or auxiliary rails like 0.8V or 0.9V |
| Reset Timeout | 210ms (min) - provides sufficient hold time for slow-starting DC-DC converters and firmware initialization |
| Supply Current | 10µA (typ) at 3.6V - enables ultra-low-power operation in battery-backed or energy-constrained systems |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and telecom base station environments |
| Reset Validity | Down to VCC1 or VCC2 = 0.8V - guarantees correct logic state even during deep undervoltage conditions |
| VCC Transient Immunity | Immune to <20µs negative glitches - prevents spurious resets from switching noise or ESD-induced supply dips |
Pinout & Package
Package: 6-pin SOT23 (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, tape-and-reel.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST / RST1 | Active-low push-pull reset output referenced to VCC1; drives high to ≥0.8×VCC1 when deasserted |
| 2 | GND | System ground reference for all comparators, timer, and output stage |
| 3 | MR | Active-low manual-reset input with internal 50kΩ pullup to VCC1; forces reset when pulled low |
| 4 | VCC2 | Secondary supply input (0.8V–5.5V); powers internal VCC2 comparator and sets RST2 reference if present |
| 5 | VCC1 | Primary supply input (0.8V–5.5V); powers device core, references RST output, and sets VCC1 comparator threshold |
| 6 | RST2 | Active-low push-pull reset output referenced to VCC2 - asserted independently on VCC1/VCC2 fault or MR low |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitors | Simultaneous VCC1 (1.575V) and VCC2 (0.788V) supervision without shared timing or logic dependencies |
| Push-pull RST and RST2 outputs | No external pullup required; full rail-to-rail drive strength supports direct interface to µP reset pins |
| 210ms factory-programmed timeout | Eliminates need for external RC timing network - improves BOM count, layout simplicity, and temperature stability |
| Guaranteed operation down to 0.8V | Ensures deterministic reset behavior during severe brownout, critical for fail-safe shutdown sequences |
| Low 10µA supply current | Reduces quiescent power in always-on monitoring paths - essential for battery-powered edge nodes |
Applications
| Telecom Power Sequencing | Industrial PLC I/O Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716AUTRVD3+ | VCC1 threshold = 4.625V (vs. 1.575V); same 6-pin SOT23, 210ms timeout, push-pull RST/RST2 | Suitable for 5V system monitoring instead of 1.6V/0.8V dual-rail; not interchangeable without PCB redesign | Select MAX6716AUTRVD3+ only when primary supply is ≥4.5V and secondary remains 0.788V |
| TLV809KDBZR | Single-supply (3.08V threshold), SOT23-3, no VCC2 monitor, 200ms timeout, open-drain RST | Lacks dual-monitoring capability and push-pull drive; requires external pullup and cannot supervise sub-1V rails | Use TLV809KDBZR only for cost-sensitive single-rail applications where VCC2 monitoring is unnecessary |
Compared with MAX6715AUTRVD3+, MAX6716AUTRVD3+ shifts VCC1 threshold upward for higher-voltage systems but retains identical timing and drive architecture, while TLV809KDBZR reduces functionality to single-rail monitoring with open-drain limitations - neither offers drop-in replacement capability.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6715AUTRVD3+?
The MAX6715AUTRVD3+ has a factory-trimmed VCC1 reset threshold of 1.575V (typical), with min/max values of 1.530V and 1.620V over temperature. This value is fixed by the "TR" suffix per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to the MAX6715AUTRVD3+ variant - not adjustable or user-configurable.
Does the MAX6715AUTRVD3+ support triple-voltage monitoring via RSTIN?
No, the MAX6715AUTRVD3+ does not include RSTIN functionality. Its part number suffix "D" indicates a dual-supply configuration without adjustable third-input capability. Only MAX6719A/MAX6720A and MAX6723A–MAX6727A variants provide RSTIN; the MAX6715AUTRVD3+ monitors only VCC1 and VCC2.
What is the function of Pin 6 (RST2) on the MAX6715AUTRVD3+?
Pin 6 of the MAX6715AUTRVD3+ is RST2 - an active-low push-pull reset output referenced to VCC2. It asserts when VCC1 or VCC2 falls below its respective threshold or when MR is pulled low, and remains asserted for the full 210ms timeout period after recovery - providing independent reset signaling for VCC2-critical subsystems.
Can the MAX6715AUTRVD3+ operate with VCC1 = 1.2V and VCC2 = 0.9V?
Yes, the MAX6715AUTRVD3+ is fully specified to operate with VCC1 as low as 0.8V and VCC2 as low as 0.8V. At VCC1 = 1.2V and VCC2 = 0.9V, it maintains valid reset output logic, monitors both rails against their factory thresholds (1.575V and 0.788V), and delivers guaranteed 210ms timeout - making it suitable for ultra-low-voltage embedded designs.
Is the reset timeout period of the MAX6715AUTRVD3+ adjustable?
No, the reset timeout period of the MAX6715AUTRVD3+ is factory-programmed to 210ms (minimum) and non-adjustable. The "D3" suffix in the part number directly encodes this fixed timeout per Maxim's Reset Timeout Period Suffix Guide - no external capacitor or resistor can modify this timing.
