Product details
Overview
MAX6715UTVHD3 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, manual reset input, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in telecom power sequencing and embedded system brownout protection.
For engineers reviewing the MAX6715UTVHD3 datasheet, MAX6715UTVHD3 pinout, MAX6715UTVHD3 application, or MAX6715UTVHD3 equivalent, this page delivers verified electrical specs, exact SOT23-6 terminal mapping, dual-supply monitoring behavior, reset timing validation, and real-world substitution guidance for industrial and networking equipment design.
Technical Context
The MAX6715UTVHD3 integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 1.575V, VTH2 = 0.788V), a 210ms reset timeout timer, and push-pull RST output referenced to VCC1. It asserts reset when either supply falls below its threshold and holds reset for ≥210ms after both supplies recover.
It features an internal 50kΩ pullup on MR, supports manual reset pulse widths ≥1µs, guarantees valid reset logic state at VCC1/VCC2 ≥ 0.8V, and draws only 14µA typical supply current at 3.6V - enabling ultra-low-power operation in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 1.575V (typ), ±2.5% over -40°C to +85°C - sets primary supply brownout detection point for 1.8V I/O rails |
| VCC2 Threshold | 0.788V (typ), ±2.5% over -40°C to +85°C - enables core voltage monitoring of sub-1V processors |
| Reset Timeout | 210ms (min), 280ms (max) - ensures sufficient hold time for FPGA configuration or boot ROM initialization |
| Supply Current | 14µA (typ) at 3.6V - allows continuous supervision in always-on subsystems without significant battery drain |
| Reset Output Type | Push-pull active-low RST, VOH ≥ 0.8×VCC1, VOL ≤ 0.4V at 3.2mA - drives CMOS inputs directly without external pullup |
| MR Input | Active-low, 50kΩ internal pullup to VCC1, VIH ≥ 0.7×VCC1 - compatible with standard logic outputs and momentary switches |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded control and telecom infrastructure |
Pinout & Package
MAX6715UTVHD3 is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with gull-wing leads and thermal pad omitted. Pin 1 marked by beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output, referenced to VCC1; asserts low during fault and holds for 210ms min after recovery |
| 2 | GND | Analog/digital ground reference for all comparators, timers, and output drivers |
| 3 | MR | Active-low manual reset input with 50kΩ internal pullup to VCC1; resets system on logic-low pulse ≥1µs |
| 4 | VCC2 | Secondary supply input (0.8V–3.3V); powers internal VCC2 comparator and sets RST2 reference if present (not used in MAX6715) |
| 5 | NC | No connect - internally unconnected; must remain floating or tied to GND per layout guidelines |
| 6 | VCC1 | Primary supply input (0.8V–5.5V); powers device core, sets RST output reference, and feeds VCC1 comparator |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous supervision of 1.8V I/O rail (VCC1) and 0.9V core rail (VCC2) with separate thresholds and hysteresis |
| Guaranteed reset validity at low VCC | Outputs remain functional and logically correct even when VCC1 or VCC2 drops to 0.8V - critical for graceful shutdown |
| Immunity to short VCC transients | Rejects negative-going glitches <20µs at 100mV overdrive - prevents spurious resets during switching noise |
| Precision factory-trimmed thresholds | VTH1 = 1.575V ±2.5%, VTH2 = 0.788V ±2.5% - eliminates external resistor networks and calibration effort |
| Low quiescent current | 14µA typical at 3.6V - extends battery life in portable instrumentation and remote sensors |
Applications
| Telecom Power Sequencing | Industrial PLC I/O Modules |
|---|---|
Use Scenario: Sequencing multiple DC/DC converters in 48V-powered base station radios where VCC1 (3.3V) and VCC2 (1.2V) must power up/down in strict order. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting reset until both rails stabilize, then releasing after 210ms timeout to enable FPGA configuration. Use Value: Prevents latch-up and bus contention during power ramp by enforcing minimum hold time and independent threshold detection. |
Use Scenario: Monitoring isolated 24V field power and 3.3V logic supply in programmable logic controller backplanes exposed to EMI and voltage sags. IC Role / Device Role / Timing Role: Fault detector triggering hardware reset on undervoltage events, with MR input enabling operator-initiated diagnostics reset. Use Value: Eliminates firmware-based watchdog reliance; provides deterministic, analog-level response to supply faults within 20µs. |
| Portable Medical Sensors | Set-Top Box Power Management |
Use Scenario: Battery-powered glucose meter with Li-ion (3.0–4.2V) and regulated 1.8V MCU core, requiring fail-safe boot integrity under partial discharge. IC Role / Device Role / Timing Role: Brownout protector asserting reset when battery drops below 3.0V (VCC1) or core regulator fails (VCC2 < 0.8V). Use Value: Ensures EEPROM writes complete before power loss via guaranteed reset assertion down to 0.8V on either rail. |
Use Scenario: Consumer STB with triple-rail power (12V, 5V, 3.3V) where 3.3V logic and 1.2V SoC core must coordinate startup and shutdown. IC Role / Device Role / Timing Role: Dual-threshold supervisor validating main and auxiliary rails before releasing processor reset and enabling HDMI PHY. Use Value: Reduces BOM count by replacing discrete reset ICs and RC networks while improving temperature stability (20ppm/°C tempco). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G15DBVR | Single-supply monitor (1.5V threshold only), no VCC2 input; 200ms timeout; open-drain RST | Lacks secondary rail monitoring - requires external circuitry to supervise core voltage | Select when only primary rail supervision is needed and board space permits external divider for VCC2 |
| ADM6715SWSZ-RL | Same dual-monitor function, but 140ms timeout (D2 suffix), open-drain RST, and 2.5µA lower ICC | Shorter timeout may not meet FPGA boot requirements; open-drain requires pullup resistor | Prefer for ultra-low-power applications where 140ms hold time suffices and pullup routing is acceptable |
Compared with TPS3808G15DBVR and ADM6715SWSZ-RL, MAX6715UTVHD3 uniquely delivers integrated dual-rail monitoring with push-pull output and 210ms timeout in a single SOT23-6 package - reducing component count and eliminating external biasing in multivoltage systems.

FAQ
What is the exact reset timeout period for MAX6715UTVHD3?
The MAX6715UTVHD3 has a minimum reset timeout period of 210ms and a maximum of 280ms, as defined by the 'D3' suffix in its part number. This timeout begins when all monitored supplies rise above their thresholds and ensures reliable processor initialization before release. The value is factory-trimmed and specified over the full -40°C to +85°C operating range.
Does MAX6715UTVHD3 support monitoring a third voltage rail?
No, MAX6715UTVHD3 is a dual-voltage supervisor and does not include the RSTIN input required for triple-voltage monitoring. That functionality is available only in MAX6719/MAX6720 and higher variants (e.g., MAX6723–MAX6729). MAX6715UTVHD3 monitors only VCC1 and VCC2 with fixed factory-trimmed thresholds.
What is the function of Pin 5 on MAX6715UTVHD3?
Pin 5 on MAX6715UTVHD3 is a no-connect (NC) terminal - it is not bonded internally and must remain unconnected on the PCB. Per Maxim's layout guidelines, NC pins should neither be tied to GND nor routed; leaving them floating avoids parasitic coupling and ensures specified ESD and noise immunity performance.
Can MAX6715UTVHD3 operate with VCC1 = 1.8V and VCC2 = 0.9V?
Yes, MAX6715UTVHD3 is fully specified to operate with VCC1 = 1.8V and VCC2 = 0.9V. Its VCC1 threshold is 1.575V and VCC2 threshold is 0.788V, both well within the valid input ranges (VCC1: 0.8V–5.5V; VCC2: 0.8V–3.3V). Reset assertion and timeout behavior remain guaranteed at these voltages.
Is the reset output of MAX6715UTVHD3 push-pull or open-drain?
The MAX6715UTVHD3 features a push-pull active-low RST output (Pin 1), referenced to VCC1. It actively drives high (≥0.8×VCC1) and low (≤0.4V at 3.2mA) without requiring an external pullup resistor - unlike open-drain variants such as MAX6715UTLTD3-T, which mandate external biasing.
