Product details
Overview
MAX6715UTSVD3-T 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 of 4.625V and 3.075V respectively, 210ms minimum reset timeout, and push-pull active-low RST output. It ensures reliable system reset during brownout or startup in multivoltage embedded systems.
For engineers reviewing the MAX6715UTSVD3-T datasheet, MAX6715UTSVD3-T pinout, MAX6715UTSVD3-T application, or MAX6715UTSVD3-T equivalent, key selection factors include its guaranteed reset validity down to VCC1/VCC2 = 0.8V, 14µA typical supply current at 3.6V, immunity to short VCC transients, and compatibility with manual reset, watchdog, and power-fail monitoring functions.
Technical Context
The MAX6715UTSVD3-T implements dual independent voltage comparators with internal 20ppm/°C tempco and 0.5% hysteresis, driving a programmable reset timeout timer. Its push-pull RST output is referenced to VCC1 and sinks up to 3.2mA at 4.5V while maintaining VOL ≤ 0.4V.
It features an internal 50kΩ pullup on MR, supports manual reset pulse widths ≥1µs, and guarantees correct reset logic state when either VCC1 or VCC2 exceeds 0.8V - enabling robust operation during deep brownout conditions without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed, falling edge; enables precise monitoring of 5V or 4.8V rails) |
| VCC2 Threshold | 3.075V (factory-trimmed, falling edge; matches common 3.3V I/O supply tolerance) |
| Reset Timeout | 210ms (minimum; ensures µP completes boot sequence before release) |
| Supply Current | 14µA typical at 3.6V (enables use in battery-backed or ultra-low-power systems) |
| Operating Temp | -40°C to +85°C (supports industrial and telecom equipment deployment) |
| Reset Output Type | Push-pull active-low RST (eliminates need for external pullup; drives directly into µP reset pin) |
| MR Input | Active-low with 50kΩ internal pullup to VCC1 (simplifies manual reset switch interface) |
Pinout & Package
MAX6715UTSVD3-T is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with gull-wing leads and thermal pad option not included.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; asserts when VCC1 < 4.625V or VCC2 < 3.075V |
| 2 | GND | Analog/digital ground reference for all comparators and timing circuits |
| 3 | MR | Active-low manual reset input with internal 50kΩ pullup to VCC1; reset persists for full timeout after release |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal VCC2 comparator and sets RST2 reference if used |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers core logic, defines RST output reference, and enables reset assertion below 4.625V |
| 6 | NC | No connect (pin 6 is unused in MAX6715 series; confirmed per Pin Description table) |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | 4.625V (VCC1) and 3.075V (VCC2) with ±1.5% accuracy over temperature - eliminates external resistor networks for standard rail monitoring |
| Guaranteed reset validity | Operates correctly with VCC1 or VCC2 ≥ 0.8V - ensures deterministic reset behavior during deep undervoltage events without auxiliary biasing |
| Low quiescent current | 14µA typical at 3.6V - extends battery life in portable equipment and reduces self-heating in dense PCB layouts |
| Transient immunity | Immune to VCC glitches < 20µs at 100mV overdrive - prevents spurious resets from switching noise or ESD-induced supply dips |
| MR integration | Internal 50kΩ pullup eliminates external component count and enables direct connection to momentary switch to GND |
Applications
| Telecom Line Card Power Management | Industrial PLC CPU Module |
|---|---|
Use Scenario: Monitors primary 4.8V backplane supply and secondary 3.3V FPGA I/O rail in carrier-grade line cards. IC Role / Device Role / Timing Role: Dual-voltage supervisor asserting active-low reset to ARM-based controller upon any rail dropout. Use Value: 210ms timeout ensures FPGA configuration completes before processor release; push-pull RST drives reset net without pullup resistor. |
Use Scenario: Ensures deterministic restart of Cortex-M7 CPU during 24VDC-to-3.3V/5V conversion faults in DIN-rail mounted PLCs. IC Role / Device Role / Timing Role: Supervises VCC1 (5.0V logic rail) and VCC2 (3.3V core rail), with MR tied to front-panel reset button. Use Value: Guaranteed reset validity down to 0.8V prevents latch-up during brownout recovery; -40°C to +85°C rating matches industrial ambient requirements. |
| Network Router Boot Integrity | Medical Infusion Pump Controller |
Use Scenario: Validates simultaneous presence of 1.2V SoC core, 3.3V PHY, and 5.0V PoE interface rails during router power-up. IC Role / Device Role / Timing Role: Dual-supply monitor triggering hardware reset if either 5.0V or 3.3V falls below threshold during boot sequence. Use Value: Factory-trimmed 4.625V/3.075V thresholds match nominal rail tolerances; 14µA supply current minimizes standby drain on backup supercap. |
Use Scenario: Secures fail-safe restart of safety-critical ARM Cortex-M4 in battery-powered infusion pumps during Li-ion voltage sag. IC Role / Device Role / Timing Role: Monitors main 3.3V MCU supply and backup 1.8V RTC rail, asserting reset before voltage drops below functional minimum. Use Value: 0.8V minimum operating voltage allows reset assertion even during deep battery depletion; SOT23-6 footprint saves space in compact enclosure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | Single-supply monitor (3.3V only); no VCC2 input; 200ms fixed timeout; open-drain RST | Lacks dual-rail capability; requires external pullup; suitable only for single-rail systems | Select when monitoring only one supply and board space permits pullup resistor |
| ADM6712S33ARTZ-RL | 3.3V fixed threshold; 200ms timeout; push-pull RST; no MR input; SOT23-5 package | Omits manual reset function; smaller footprint but no field-service reset capability | Choose for cost-sensitive, single-threshold applications where MR is unnecessary |
Compared with MAX6715UTSVD3-T, TPS3808G33DBVR lacks dual-voltage monitoring and requires external biasing, while ADM6712S33ARTZ-RL omits manual reset and offers no VCC2 supervision - making MAX6715UTSVD3-T uniquely suited for systems requiring coordinated two-rail validation with field-service reset.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on MAX6715UTSVD3-T?
The MAX6715UTSVD3-T has factory-trimmed reset thresholds of 4.625V for VCC1 (primary supply) and 3.075V for VCC2 (secondary supply), as indicated by the "TS" suffix per Maxim's Reset Voltage Threshold Suffix Guide. These values are specified at 25°C with ±1.5% tolerance over the full -40°C to +85°C operating range, and include 0.5% hysteresis to prevent chatter near trip points.
Does MAX6715UTSVD3-T support manual reset, and how is it implemented?
Yes, MAX6715UTSVD3-T includes an active-low manual reset input (MR) on pin 3 with an internal 50kΩ pullup resistor to VCC1. Pulling MR low for ≥1µs forces an immediate reset assertion, which remains active for the full 210ms timeout period after MR returns high. No external components are required - a simple momentary switch from MR to GND suffices.
What is the reset output type and drive capability of MAX6715UTSVD3-T?
MAX6715UTSVD3-T features a push-pull active-low RST output on pin 1, referenced to VCC1. It can sink up to 3.2mA at VCC1 = 4.5V while maintaining VOL ≤ 0.4V, and sources up to 800µA with VOH ≥ 0.8 × VCC1. This eliminates the need for an external pullup resistor and allows direct interfacing with µP reset pins.
Can MAX6715UTSVD3-T operate reliably during deep supply brownout?
Yes, MAX6715UTSVD3-T guarantees valid reset output logic state as long as either VCC1 or VCC2 remains above 0.8V - a key differentiator for brownout resilience. This is achieved via internal biasing and comparator design, enabling deterministic reset assertion even when supplies collapse below typical LDO dropout voltages.
What package and environmental ratings does MAX6715UTSVD3-T have?
MAX6715UTSVD3-T is supplied in a RoHS-compliant 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm) and is rated for operation from -40°C to +85°C. It meets JEDEC J-STD-020 moisture sensitivity level MSL3 and supports reflow soldering per industry standards, making it suitable for automated manufacturing in industrial and telecom applications.
