Product details
Overview
MAX6715UTZGD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (4.625V factory-trimmed threshold) and VCC2 (3.075V factory-trimmed 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 server motherboard voltage supervision.
For engineers reviewing the MAX6715UTZGD3 datasheet, MAX6715UTZGD3 pinout, MAX6715UTZGD3 application, or MAX6715UTZGD3 equivalent, this page delivers verified electrical specs, exact pin functions, dual-supply monitoring context, reset timing behavior under brownout, and validated alternative parts for industrial-grade µP supervision where supply margin and glitch immunity are critical.
Technical Context
The MAX6715UTZGD3 implements independent dual-voltage monitoring with factory-trimmed thresholds: VTH1 = 4.625V (±125mV) on VCC1 and VTH2 = 3.075V (±75mV) on VCC2, both referenced to internal bandgap references with 20ppm/°C tempco. Reset assertion occurs when either supply falls below its threshold, and reset remains asserted for ≥210ms after both supplies recover.
It features a push-pull RST output referenced to VCC1, an internal 50kΩ pullup on MR, and immunity to VCC transients ≤20µs at 100mV overdrive. Supply current is 14µA typical at 3.6V, enabling use in battery-backed systems requiring ultra-low quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (min 4.500V, max 4.750V) - sets precise brownout detection point for primary 5V or 4.8V rails |
| VCC2 Threshold | 3.075V (min 3.000V, max 3.150V) - enables reliable monitoring of secondary 3.3V I/O or core supplies |
| Reset Timeout | 210ms (min) - ensures sufficient hold time for processor initialization and peripheral settling |
| Supply Current | 14µA typical at 3.6V - supports >10-year battery life in always-on supervisory applications |
| Operating Temp | -40°C to +85°C - qualified for industrial and telecom equipment environments |
| Reset Output Type | Push-pull active-low - eliminates need for external pullup and drives directly into µP reset pin |
| MR Input Logic | Active-low with 50kΩ internal pullup to VCC1 - simplifies manual reset switch interface without external components |
Pinout & Package
MAX6715UTZGD3 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; asserts low during VCC1/VCC2 undervoltage or MR activation |
| 2 | GND | System ground reference for all internal comparators, timers, and output drivers |
| 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 VTH2 = 3.075V |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers device core and sets VTH1 = 4.625V |
| 6 | NC | No connect - pin left unconnected per datasheet; not bonded or functional |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed thresholds | VTH1 = 4.625V ±125mV and VTH2 = 3.075V ±75mV - eliminates external resistor networks and calibration effort |
| Guaranteed reset validity | Operates correctly with VCC1 or VCC2 ≥ 0.8V - ensures robust reset assertion during deep brownout conditions |
| Glitch-immune monitoring | Immune to VCC transients ≤20µs at 100mV overdrive - prevents spurious resets from switching noise or ESD |
| Low quiescent current | 14µA typical at 3.6V - enables integration into energy-sensitive systems like remote sensors or backup controllers |
| Integrated MR pullup | 50kΩ internal pullup to VCC1 - reduces BOM count and PCB space vs. discrete pullup resistor |
Applications
| Telecom Power Sequencing | Server Motherboard Supervision |
|---|---|

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 SOT23-6 package and 210ms timeout, but open-drain RST output instead of push-pull | Requires external pullup resistor; suitable where level-shifting or wired-OR reset bus is needed | Select MAX6716UTLTD3-T only if system requires open-drain reset for shared reset bus topology |
| TPS3808G33DBVR | Single-supply monitor (3.3V threshold only), 200ms timeout, 1.6µA IQ, SOT23-6 | Lacks VCC2 monitoring capability; no manual reset input; lower supply current but no dual-rail support | Choose TPS3808G33DBVR only for cost-sensitive single-rail applications where secondary supply supervision is handled elsewhere |
Compared with MAX6715UTZGD3, MAX6716UTLTD3-T offers identical timing and thresholds but requires external biasing for reset signaling, while TPS3808G33DBVR reduces quiescent current by 90% but sacrifices dual-supply monitoring and manual reset - making MAX6715UTZGD3 the only option meeting simultaneous VCC1/VCC2 supervision, push-pull drive, and MR functionality in one SOT23-6 IC.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6715UTZGD3?
The MAX6715UTZGD3 has a factory-trimmed VCC1 reset threshold of 4.625V, with guaranteed min/max limits of 4.500V and 4.750V across temperature and process variation. This value is encoded in the 'ZG' suffix per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to the MAX6715UTZGD3, not the broader MAX6715 family.
Does MAX6715UTZGD3 support monitoring a third voltage rail?
No, MAX6715UTZGD3 is a dual-supply supervisor only. It monitors VCC1 and VCC2 exclusively. The 'UT' prefix and 'D3' timeout suffix confirm it belongs to the MAX6715 series, which lacks RSTIN, WDI, PFI, or PFO pins - unlike MAX6719/MAX6720/MAX6723–MAX6729 variants that add triple-voltage or watchdog capability.
What is the function of Pin 6 on MAX6715UTZGD3?
Pin 6 on MAX6715UTZGD3 is NC (No Connect) - it is not bonded internally and must remain unconnected on the PCB. This is explicitly confirmed in the Pin Description table for MAX6715/MAX6716 devices, where Pin 6 is marked blank for all functions and designated as nonfunctional.
Can MAX6715UTZGD3 operate with VCC1 = 1.8V?
No, MAX6715UTZGD3 requires VCC1 ≥ 1.8V only for valid operation above its reset threshold - but its factory-trimmed VTH1 = 4.625V means it is intended for 4.5V–5.0V primary rails. Operation at 1.8V would place VCC1 far below VTH1, causing continuous reset assertion and violating the device's specified VCC1 range of 1.8V to 5.0V for functional monitoring.
What does the 'D3' suffix indicate in MAX6715UTZGD3?
The 'D3' suffix in MAX6715UTZGD3 specifies a minimum reset timeout period of 210ms, per Maxim's Reset Timeout Period Suffix Guide. This value is fixed for this variant and defines the guaranteed duration RST remains low after recovery of both monitored supplies, independent of temperature or supply voltage within operating range.
