Product details
Overview
MAX6715AUTVHD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (4.625V factory-trimmed threshold) and VCC2 (3.075V threshold) with 140ms minimum reset timeout, push-pull active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V. It is used in telecom power management systems to ensure reliable cold-start and brownout recovery.
For engineers reviewing the MAX6715AUTVHD3+T datasheet, MAX6715AUTVHD3+T pinout, MAX6715AUTVHD3+T application, or MAX6715AUTVHD3+T equivalent, key selection criteria include dual-rail voltage monitoring accuracy (±1.5% over -40°C to +125°C), 14μA typical supply current at 3.6V, immunity to sub-20µs VCC transients, and compatibility with manual-reset and watchdog-disabled configurations.
Technical Context
The MAX6715AUTVHD3+T integrates two independent voltage comparators with internal 1.25V reference and resistor-divider scaling to deliver precise factory-trimmed thresholds for primary (VCC1) and secondary (VCC2) rails. Its reset logic combines OR-ed fault detection across both supplies with a monolithic timeout counter ensuring minimum 140ms assertion after all voltages recover.
It features a push-pull RST output referenced to VCC1, internal 50kΩ MR pullup, and no watchdog or RSTIN/PFI functionality-confirmed by suffix "VHD3", where "V" = VCC1=4.625V, "H" = VCC2=3.075V, "D3" = 140ms timeout, and absence of W/R/P/F codes indicates no WDI, RSTIN, PFI, or PFO functions enabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Reset Threshold | 4.625V (factory-trimmed, ±1.5% over temp; ensures reliable reset assertion before 4.5V logic rail collapse) |
| VCC2 Reset Threshold | 3.075V (factory-trimmed, ±1.5% over temp; matches common 3.3V I/O supply derating margin) |
| Reset Timeout Period | 140ms min (D3 suffix; provides sufficient time for FPGA configuration or DDR initialization post-power-up) |
| Supply Current | 14μA typ at 3.6V (enables use in always-on battery-backed subsystems without significant drain) |
| Operating Temperature | -40°C to +125°C (AEC-Q100–compatible grade; validated for under-hood automotive and industrial edge nodes) |
| Reset Validity Voltage | 0.8V on VCC1 or VCC2 (guaranteed correct RST logic state during deep brownout, enabling fail-safe shutdown) |
| Output Type | Push-pull active-low RST (no external pullup required; drives directly into μP reset pin with 0.3V VOL @ 1.2mA sink) |
Pinout & Package
SOT23-6 package (package code U6+1), 1.6mm × 2.9mm footprint, 1.1mm height, thermal resistance θJA = 115°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; asserted when VCC1 < 4.625V or VCC2 < 3.075V; referenced to VCC1 |
| 2 | GND | System ground reference for all comparators and output drivers |
| 3 | MR | Active-low manual-reset input; internal 50kΩ pullup to VCC1; 1µs minimum pulse width required |
| 4 | VCC2 | Secondary supply input (3.075V threshold monitor); powers internal circuitry when > VCC1 |
| 5 | VCC1 | Primary supply input (4.625V threshold monitor); powers device when > VCC2; defines RST output voltage levels |
| 6 | NC | No connect; unused pin per MAX6715A variant pinout; must be left floating or tied to GND |
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 operation at low VCC | Valid RST logic state maintained even if VCC1 or VCC2 drops to 0.8V - critical for graceful brownout handling |
| Low quiescent current | 14μA typical ICC at 3.6V enables integration into energy-sensitive applications like remote sensors |
| Immunity to short VCC transients | Rejects negative-going glitches < 20µs duration (at 100mV overdrive), preventing spurious resets |
| Precision factory-trimmed thresholds | ±1.5% tolerance over full temperature range eliminates need for external calibration components |
Applications
| Telecom Power Sequencing | Industrial PLC I/O Module |

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6715AUTVHD3+T?
The MAX6715AUTVHD3+T has factory-trimmed reset thresholds of 4.625V (±1.5%) for VCC1 and 3.075V (±1.5%) for VCC2, as defined by the "VH" suffix per Maxim's Reset Voltage Threshold Suffix Guide. These values are guaranteed over -40°C to +125°C and do not require external calibration. The MAX6715AUTVHD3+T uses no adjustable inputs - all thresholds are fixed at wafer sort.
Does the MAX6715AUTVHD3+T support watchdog timer functionality?
No, the MAX6715AUTVHD3+T does not include watchdog timer capability. Its suffix "VHD3" contains no "W" code, and the pinout confirms WDI is unassigned (pin 6 is NC). Watchdog functionality is only present in variants with "W" in the suffix (e.g., MAX6721A). The MAX6715AUTVHD3+T provides pure dual-supply voltage supervision with manual reset only.
What is the function of pin 6 on the MAX6715AUTVHD3+T?
Pin 6 on the MAX6715AUTVHD3+T is a no-connect (NC) terminal. Per Maxim's Pin Description table, this pin is unused in the MAX6715A variant and must be left floating or tied to GND - it is not bonded internally and carries no electrical function. Connecting it to any signal or voltage may compromise SOT23-6 package integrity or cause assembly defects.
Can the MAX6715AUTVHD3+T monitor a third voltage rail?
No, the MAX6715AUTVHD3+T cannot monitor a third voltage rail. It is a dual-supply supervisor only, with dedicated VCC1 and VCC2 inputs. Third-rail monitoring requires variants with "RSTIN" or "PFI" functionality (e.g., MAX6719A or MAX6728A), indicated by "R" or "P" in the suffix. The MAX6715AUTVHD3+T lacks RSTIN, PFI, and associated pins - its functionality is strictly limited to two factory-set thresholds.
What is the minimum supply voltage at which the MAX6715AUTVHD3+T guarantees valid reset output behavior?
The MAX6715AUTVHD3+T guarantees correct RST output logic state down to VCC1 = 0.8V or VCC2 = 0.8V, as specified in Absolute Maximum Ratings and Electrical Characteristics. This ensures fail-safe reset assertion during deep brownout conditions. Below 0.8V, reset behavior is not characterized - thus, the MAX6715AUTVHD3+T enables robust power-fail response where other supervisors would lose control.
