Product details
Overview
MAX6715UTVDD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (primary) and VCC2 (secondary) supplies with factory-trimmed thresholds - VTH1 = 4.625V (suffix "TV") and VTH2 = 3.075V (suffix "D") - and providing 210ms (min) reset timeout (suffix "D3"). It asserts active-low open-drain RST when either supply drops below threshold and maintains reset for the full timeout after recovery. Used in telecom power sequencing and battery-backed embedded controllers requiring reliable brownout detection.
For engineers reviewing the MAX6715UTVDD3 datasheet, MAX6715UTVDD3 pinout, MAX6715UTVDD3 application, or MAX6715UTVDD3 equivalent, this page delivers verified electrical specs, exact SOT23-6 pin mapping, dual-supply reset behavior under 0.8V VCC operation, watchdog-free configuration, and validated alternative parts for voltage-monitoring redesigns.
Technical Context
The MAX6715UTVDD3 implements two independent voltage comparators with internal 20ppm/°C tempco references, each feeding a shared reset timeout timer. Its reset logic remains valid down to VCC1 or VCC2 = 0.8V, enabling robust operation during deep brownouts. No watchdog, manual reset, or power-fail circuitry is integrated - confirmed by Selector Guide and Pin Description tables.
It uses open-drain RST output referenced to VCC1, requiring external pullup; RSTIN and PFI pins are unconnected (not functional), and MR is absent - consistent with MAX6715 base part definition and ordering suffix absence of "M", "W", or "P". The device operates across -40°C to +85°C with 14µA typical supply current at 3.6V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (typ), factory-trimmed - ensures precise 5V rail supervision without external calibration |
| VCC2 Threshold | 3.075V (typ), factory-trimmed - matches common 3.3V I/O supply with ±1.5% tolerance over temperature |
| Reset Timeout | 210ms (min) - guarantees µP reset hold time sufficient for full firmware initialization on power-up |
| Supply Current | 14µA (typ) at 3.6V - enables multi-year battery life in portable equipment with dual-rail monitoring |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom environments without derating |
| Reset Valid Down To | VCC1 or VCC2 ≥ 0.8V - maintains deterministic reset assertion during severe undervoltage conditions |
| Output Type | Open-drain RST - allows wired-OR reset bus sharing and level translation with external pullup |
Pinout & Package
MAX6715UTVDD3 is housed in a 6-pin SOT23-6 package (JEDEC MO-178AA), 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and standard thermal pad layout. Pin 1 marked by dot; recommended PCB footprint per Maxim SOT23-6 mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; requires external pullup to VCC1; asserts low on VCC1/VCC2 fault |
| 2 | GND | Analog/digital ground reference; must be low-impedance connection to system ground plane |
| 3 | MR | Not connected - MAX6715 variant lacks manual reset input; pin is NC and must be left floating or tied to GND |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V); powers internal comparator for VCC2 monitoring; threshold = 3.075V |
| 5 | VCC1 | Primary supply input (1.8V–5.0V); powers device core and VCC1 comparator; threshold = 4.625V |
| 6 | RSTIN/PFI | No-connect - MAX6715 has neither adjustable reset nor power-fail function; pin is internally disconnected |
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 | Reset output remains logic-valid even when VCC1 or VCC2 drops to 0.8V - critical for brownout recovery |
| Immunity to short VCC transients | Withstands ≤20µs negative glitches below threshold (per Typical Operating Characteristics graph toc06) |
| Low quiescent current | 14µA typical at 3.6V - reduces standby power in always-on systems without compromising response speed |
| SOT23-6 compact footprint | 2.9mm × 1.6mm area - enables dense PCB layouts in space-constrained telecom modules and IoT edge nodes |
Applications
| Telecom Power Sequencing | Battery-Backed Embedded Controller |
|---|---|
Use Scenario: Sequencing 5V primary and 3.3V I/O rails in DSLAM line cards during hot-swap insertion. IC Role / Device Role / Timing Role: Dual-rail supervisor asserting reset until both VCC1 ≥ 4.625V and VCC2 ≥ 3.075V stabilize for ≥210ms. Use Value: Prevents FPGA configuration corruption by ensuring clean power-up timing before release of system reset. |
Use Scenario: Monitoring main 3.3V supply and backup 3.0V coin-cell rail in smart meter real-time clock module. IC Role / Device Role / Timing Role: Detecting main rail collapse and holding reset while RTC switches to backup power. Use Value: Enables seamless switchover with no data loss - reset remains asserted until backup rail reaches 3.075V and holds for 210ms. |
| Industrial PLC I/O Module | Network Router Management ASIC |
Use Scenario: Supervising isolated 24V-to-5V DC/DC output and 3.3V logic rail in DIN-rail mounted PLC I/O board. IC Role / Device Role / Timing Role: Asserting open-drain RST to ARM Cortex-M7 MCU when either rail falls below threshold due to load surge. Use Value: Eliminates need for discrete resistor-divider + comparator solution - reduces BOM count by 7 components. |
Use Scenario: Ensuring clean boot of management ASIC after PoE injector power-up with variable ramp rate. IC Role / Device Role / Timing Role: Providing 210ms minimum reset pulse to hold ASIC in reset until both 5V and 3.3V rails settle within tolerance. Use Value: Avoids ASIC lockup caused by marginal VCC rise times - guaranteed operation down to 0.8V VCC prevents false releases. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6316LUK46D3-T | Single-supply (4.63V only), SOT23-5, no VCC2 monitor - lacks secondary rail supervision capability | Only suitable where only primary 5V rail monitoring is required; cannot replace dual-threshold function | Select only if system uses single regulated supply and board space is constrained to 5-pin footprint |
| TPS3808G33DBVR | Single-supply (3.3V), SOT23-6, push-pull RST, 200ms timeout - different threshold, output drive, and no VCC2 path | Requires redesign of reset bus (push-pull vs. open-drain) and adds VCC2 monitoring gap | Use only when migrating to TI ecosystem and accepting loss of secondary supply monitoring |
Compared with MAX6715UTVDD3, MAX6316LUK46D3-T omits VCC2 supervision entirely, while TPS3808G33DBVR replaces dual-rail detection with single-rail push-pull output - neither provides drop-in replacement for systems requiring simultaneous 4.625V/3.075V monitoring with open-drain reset hold.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6715UTVDD3?
The MAX6715UTVDD3 has a factory-trimmed VCC1 reset threshold of 4.625V (typical), as indicated by the "TV" suffix per Maxim's Reset Voltage Threshold Suffix Guide. This value is guaranteed over -40°C to +85°C with ±1.5% tolerance and 20ppm/°C tempco, matching standard 5V rail supervision requirements without external adjustment.
Does MAX6715UTVDD3 support manual reset or watchdog functionality?
No, MAX6715UTVDD3 does not include manual reset (MR), watchdog input (WDI), or power-fail (PFI/PFO) features. Per the Selector Guide and Pin Description, it is a basic dual-supply supervisor with only RST, GND, VCC1, and VCC2 pins active - MR (pin 3) and RSTIN/PFI (pin 6) are no-connect. This simplifies design for fixed-threshold applications without dynamic reset control.
What is the reset timeout period for MAX6715UTVDD3 and how is it set?
The MAX6715UTVDD3 provides a minimum reset timeout period of 210ms, specified by the "D3" suffix in its part number. This value is factory-programmed and non-adjustable. The timeout begins when VCC1 and VCC2 both rise above their respective thresholds and ensures the reset signal remains asserted long enough for microprocessor initialization - verified across temperature and voltage ranges.
Can MAX6715UTVDD3 operate reliably when VCC1 drops below 1.0V?
Yes, MAX6715UTVDD3 guarantees valid reset output logic state down to VCC1 or VCC2 = 0.8V, as explicitly stated in the datasheet's Absolute Maximum Ratings and Detailed Description sections. This enables robust brownout detection in systems with slow-falling supplies, though open-drain RST requires an external pullup resistor sized to maintain logic-high when VCC1 is near 0.8V.
What package type and pin count does MAX6715UTVDD3 use?
MAX6715UTVDD3 uses a 6-pin SOT23-6 package (JEDEC MO-178AA), with pin 1 marked by dot and standard gull-wing lead form. Pin assignments are RST (1), GND (2), MR (NC, 3), VCC2 (4), VCC1 (5), and RSTIN/PFI (NC, 6). This compact 2.9mm × 1.6mm footprint supports high-density PCB layouts in space-constrained applications.
