Product details
Overview
MAX6715UTSHD3 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 multivoltage telecom power sequencing.
For engineers reviewing the MAX6715UTSHD3 datasheet, MAX6715UTSHD3 pinout, MAX6715UTSHD3 application, or MAX6715UTSHD3 equivalent, this page delivers verified functional identity, exact threshold values, timeout timing, reset output logic, and validated alternative options for dual-supply supervision in space-constrained industrial and networking systems.
Technical Context
The MAX6715UTSHD3 implements two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a 210ms min 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 the full timeout after recovery.
It includes an internal 50kΩ pullup on MR, supports manual reset pulse widths ≥1µs, and guarantees correct reset state at VCC1/VCC2 ≥ 0.8V. No watchdog, RSTIN, PFI, or PFO functions are present - confirmed by Selector Guide and Ordering Information.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed falling threshold; enables reliable 5V rail supervision) |
| VCC2 Threshold | 3.075V (factory-trimmed falling threshold; matches common 3.3V I/O supply) |
| Reset Timeout | 210ms min (ensures µP completes boot before release; avoids premature release during brownout recovery) |
| Reset Output Type | Push-pull active-low (drives high/low without external pullup; compatible with bidirectional µP reset pins via series resistor) |
| Supply Current | 14µA typ at 3.6V (enables battery-backed operation >10 years in low-power systems) |
| Operating Temp | -40°C to +85°C (supports industrial-grade deployment without derating) |
| Reset Valid Down To | VCC1 or VCC2 ≥ 0.8V (ensures deterministic reset assertion during deep brownout) |
Pinout & Package
Package: 6-pin SOT23-6, surface-mount, lead-free compatible (-T suffix), footprint compatible with industry-standard SOT23-6 land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; drives low during fault and remains low for 210ms min after recovery |
| 2 | GND | Ground reference for all internal comparators, timers, and output drivers |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1 (50kΩ); asserts reset when pulled ≤0.3×VCC1 |
| 4 | VCC2 | Secondary supply input; powers internal circuitry when VCC2 > VCC1 and sets VTH2 = 3.075V monitor reference |
| 5 | VCC1 | Primary supply input; powers device when VCC1 > VCC2 and sets VTH1 = 4.625V monitor reference |
| 6 | NC | No connect; unused pin; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Dual factory-trimmed voltage monitoring | Eliminates external resistor dividers for VCC1=4.625V and VCC2=3.075V, reducing BOM count and layout area |
| 210ms minimum reset timeout | Guarantees µP reset hold time exceeds typical boot sequences in embedded telecom processors |
| Push-pull RST output | Removes need for external pullup resistor, simplifying interface to µP reset pins and reducing standby current |
| MR with internal 50kΩ pullup | Enables momentary switch reset without external components; supports TTL/CMOS drive |
| Valid reset down to 0.8V supply | Ensures deterministic reset assertion during severe brownout, preventing undefined µP behavior |

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 | Requires external divider for 5V rail monitoring; needs pullup resistor; less flexible for dual-rail validation | Select only if monitoring one rail and board space permits added divider/pullup |
| ADM6715S462ARTZ-R7 | 4.62V VCC1 threshold, 200ms timeout, push-pull RST, but no MR input; SOT23-5 package | Lacks manual reset capability; smaller footprint but no field-service reset option | Choose when manual reset is unnecessary and PCB area is critical |
Compared with TPS3808G33DBVR and ADM6715S462ARTZ-R7, the MAX6715UTSHD3 uniquely provides factory-matched dual-threshold supervision (4.625V/3.075V), integrated MR, and 210ms timeout in a single SOT23-6 - eliminating design compromises required by single-rail or MR-less alternatives.

FAQ
What is the exact reset threshold voltage for VCC1 on the MAX6715UTSHD3?
The MAX6715UTSHD3 has a factory-trimmed VCC1 reset threshold of 4.625V (minimum 4.500V, maximum 4.750V) specified at falling edge. This value is encoded in the "SH" suffix per Maxim's Reset Voltage Threshold Suffix Guide and is validated across -40°C to +85°C. The MAX6715UTSHD3 uses this precise threshold to supervise standard 5V rails without external calibration.
Does the MAX6715UTSHD3 support watchdog functionality?
No, the MAX6715UTSHD3 does not include watchdog functionality. Per Maxim's Selector Guide, only MAX6721–MAX6729 variants feature WDI input. The MAX6715UTSHD3 is a dual-supply supervisor with manual reset (MR) and push-pull RST output only - confirmed by pin configuration (no WDI pin) and absence of watchdog timing parameters in its electrical characteristics table.
What is the function of Pin 6 on the MAX6715UTSHD3?
Pin 6 on the MAX6715UTSHD3 is NC (No Connect). It is an unused terminal with no internal connection, as confirmed by the Pin Description table and Functional Diagram in the datasheet. Maxim specifies it must be left floating or tied to GND for mechanical stability - it must never be connected to VCC or signal lines to avoid unintended coupling or ESD paths.
Can the MAX6715UTSHD3 monitor a 1.8V supply as VCC2?
No, the MAX6715UTSHD3 cannot reliably monitor a 1.8V supply as VCC2. Its VCC2 threshold is factory-trimmed to 3.075V (suffix "H"), and the device requires VCC2 ≥ 0.8V to guarantee valid reset operation - but the monitored voltage must exceed the programmed threshold to avoid spurious reset. For 1.8V rail supervision, a different variant (e.g., MAX6715UTLHD3 with VTH2 = 1.710V) or alternate supervisor is required.
What is the reset timeout period of the MAX6715UTSHD3 and how is it set?
The MAX6715UTSHD3 has a minimum reset timeout period of 210ms, set by the "D3" suffix per Maxim's Reset Timeout Period Suffix Guide. This value is factory-programmed and non-adjustable. The timeout begins when reset is asserted and continues unconditionally - even if supplies recover earlier - ensuring µP reset hold time meets JEDEC and IPC standards for reliable boot initialization.
