Product details
Overview
MAX6715UTRVD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (primary supply) and VCC2 (secondary supply) with factory-trimmed reset thresholds of 4.625V (VTH1) and 3.075V (VTH2), 210ms minimum reset timeout, and push-pull active-low RST output. It guarantees valid reset assertion down to VCC1 or VCC2 = 0.8V and supports manual reset input (MR) for system-level recovery in telecom power management and embedded controllers.
For engineers reviewing the MAX6715UTRVD3 datasheet, MAX6715UTRVD3 pinout, MAX6715UTRVD3 application, or MAX6715UTRVD3 equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% over temperature), low 14µA typical supply current at 3.6V, immunity to sub-20µs VCC transients, and guaranteed operation across -40°C to +85°C industrial temperature range.
Technical Context
The MAX6715UTRVD3 implements independent voltage comparators for VCC1 and VCC2, each referenced to a precision internal bandgap, with 20ppm/°C tempco and 0.5% hysteresis. Its reset logic asserts RST low when either supply falls below its trimmed threshold and holds for a fixed 210ms (min) timeout after both supplies recover.
This device uses a dedicated MR input with 50kΩ internal pullup to VCC1, 1µs minimum pulse width requirement, and 200ns MR-to-reset delay. It lacks watchdog, RSTIN, PFI/PFO, or RST2 functionality-confirmed by Selector Guide and Pin Configuration tables specific to MAX6715.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (typ), ±1.5% over -40°C to +85°C - sets primary supply brownout detection point for 5V rail systems |
| VCC2 Threshold | 3.075V (typ), ±1.5% over -40°C to +85°C - enables reliable monitoring of 3.3V I/O or auxiliary rails |
| Reset Timeout | 210ms (min) - ensures µP completes full initialization before release from reset |
| Supply Current | 14µA (typ) at 3.6V - minimizes quiescent power in battery-backed or energy-sensitive applications |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom equipment without derating |
| Reset Output | Push-pull, active-low RST - drives directly into µP reset pin without external pullup; VOL ≤ 0.4V @ 3.2mA |
| VCC Valid Range | 0.8V to 5.5V - guarantees correct reset state even during deep brownout conditions |
Pinout & Package
MAX6715UTRVD3 is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with gull-wing leads and thermal pad not connected internally.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; referenced to VCC1; sinks up to 3.2mA; asserts when VCC1 < 4.625V or VCC2 < 3.075V |
| 2 | GND | Analog/digital ground reference for all comparators and output drivers |
| 3 | MR | Active-low manual reset input; 50kΩ internal pullup to VCC1; 1µs minimum pulse width; resets system on demand |
| 4 | VCC2 | Secondary supply input; powers internal circuitry when VCC2 > VCC1; monitored at 3.075V threshold |
| 5 | VCC1 | Primary supply input; powers internal circuitry when VCC1 > VCC2; monitored at 4.625V threshold |
| 6 | NC | No connect - pin 6 is unused and must remain floating per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitors | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision eliminates need for two discrete supervisors |
| Guaranteed reset validity down to 0.8V | Ensures deterministic reset behavior during severe brownout, critical for fail-safe embedded boot sequences |
| Push-pull RST output | Drives µP reset pin directly without external pullup resistor, reducing BOM count and PCB area |
| Low 14µA supply current | Enables use in always-on subsystems (e.g., RTC backup, wake-on-event circuits) without significant battery drain |
| Immunity to short VCC transients | Rejects glitches <20µs duration, preventing spurious resets in noisy power environments |
Applications
| Telecom Power Sequencing | Industrial PLC Controller |
|---|---|
|
Use Scenario: Monitoring 5V primary and 3.3V I/O rails in a line-card power management unit. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting reset until both rails stabilize post-power-up or fault recovery. Use Value: Prevents firmware execution on marginal rails; 210ms timeout aligns with DC/DC converter soft-start timing. |
Use Scenario: Ensuring safe startup of ARM-based controller in programmable logic controller with isolated 5V and 3.3V domains. IC Role / Device Role / Timing Role: Primary reset generator coordinating CPU, FPGA, and peripheral initialization sequence. Use Value: Push-pull RST eliminates external pullup; 0.8V reset validity guards against undervoltage lockout failure modes. |
| Network Switch ASIC Boot | Medical Diagnostic Module |
|
Use Scenario: Supervising core (1.2V) and I/O (3.3V) supplies during ASIC boot in enterprise switch fabric. IC Role / Device Role / Timing Role: Secondary-supply monitor (VCC2 = 3.3V) paired with upstream 1.2V supervisor via MR chaining. Use Value: MR input allows coordinated multi-rail reset propagation; 14µA ICC enables low-power standby mode. |
Use Scenario: Providing fail-safe reset for patient-monitoring MCU during AC/DC adapter transitions or battery switchover. IC Role / Device Role / Timing Role: Brownout detector for main 5V and backup 3.3V rails, triggering controlled shutdown on sustained undervoltage. Use Value: ±1.5% threshold tolerance ensures repeatable trip points across production units and temperature extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716UTLTD3-T | Same package and thresholds, but open-drain RST output requiring external pullup | Suitable where level-shifting or wired-OR reset bus is needed | Select MAX6716UTLTD3-T only if system requires open-drain reset for bus sharing or voltage translation |
| TPS3808G33DBVR | Single-supply (3.3V only), 200ms timeout, 3.08V threshold, 1.6µA ICC - no VCC2 monitoring capability | Limited to single-rail systems; lower quiescent current but no dual-supply coordination | Choose TPS3808G33DBVR only for cost-sensitive 3.3V-only designs where secondary rail supervision is unnecessary |
Compared with MAX6715UTRVD3, MAX6716UTLTD3-T trades push-pull drive for bus-sharing flexibility, while TPS3808G33DBVR reduces cost and current but sacrifices dual-supply coordination-making MAX6715UTRVD3 uniquely suited for multirail integrity assurance.

FAQ
What is the exact reset timeout period of the MAX6715UTRVD3?
The MAX6715UTRVD3 has a minimum reset timeout period of 210ms, as indicated by the 'D3' suffix in its part number per the Reset Timeout Period Suffix Guide. This is the guaranteed minimum duration RST remains asserted after all monitored supplies recover above their thresholds, ensuring sufficient time for microprocessor initialization before release.
Does the MAX6715UTRVD3 support watchdog or power-fail monitoring?
No, the MAX6715UTRVD3 does not include watchdog timer (WDI), power-fail input/output (PFI/PFO), or adjustable RSTIN functionality. Per the Selector Guide and Pin Configuration tables, it is a basic dual-supply supervisor with only VCC1, VCC2, MR, and push-pull RST. These features are present only in higher-numbered variants like MAX6721–MAX6729.
What are the precise reset threshold voltages for MAX6715UTRVD3?
The MAX6715UTRVD3 has factory-trimmed reset thresholds of 4.625V (VTH1) for VCC1 and 3.075V (VTH2) for VCC2, with ±1.5% tolerance over -40°C to +85°C. These values are defined by the 'RV' suffix per the Reset Voltage Threshold Suffix Guide and confirmed in the Electrical Characteristics table.
Can MAX6715UTRVD3 operate with VCC1 = 3.3V and VCC2 = 1.8V?
Yes, MAX6715UTRVD3 supports VCC1 from 1.8V to 5.0V and VCC2 from 0.9V to 3.3V per the General Description. However, its fixed thresholds (4.625V/3.075V) mean it is optimized for 5V/3.3V systems. Using it with 3.3V/1.8V rails would result in undervoltage detection only if those rails drop far below nominal-so it remains functional but not optimally matched.
Is pin 6 of MAX6715UTRVD3 connected internally?
No, pin 6 of MAX6715UTRVD3 is designated NC (No Connect) and must remain unconnected per the Pin Description table. It is not bonded internally and serves no electrical function; routing or soldering to this pin may cause assembly defects or reliability issues.
