Product details
Overview
MAX6715AUTYHD3+T from Maxim Integrated is a dual-supply ultra-low-voltage microprocessor supervisory circuit in SOT23-5 package, monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V) with factory-trimmed reset thresholds, 14µA typical supply current, and 140ms minimum reset timeout period. It asserts active-low open-drain RST when either supply falls below threshold and maintains reset for the full timeout after recovery - used in telecom power sequencing and battery-backed industrial controllers.
For engineers reviewing the MAX6715AUTYHD3+T datasheet, MAX6715AUTYHD3+T pinout, MAX6715AUTYHD3+T application, or MAX6715AUTYHD3+T equivalent, key selection criteria include dual-rail voltage monitoring capability, guaranteed reset validity down to VCC = 0.8V, open-drain RST output referenced to VCC1, and compatibility with manual-reset and watchdog-disabled configurations.
Technical Context
The MAX6715AUTYHD3+T implements independent comparators for VCC1 and VCC2, each with ±0.5% hysteresis and 20ppm/°C tempco, ensuring stable threshold behavior across -40°C to +125°C. Its internal reset timeout timer is fixed at 140ms (suffix D3), non-adjustable, and restarts on any threshold violation before timeout completion.
No RSTIN, WDI, PFI, or PFO pins are present on this variant - confirmed by its SOT23-5 pinout and ordering suffix TYHD3, indicating primary/secondary supply monitoring only, with MR input and open-drain RST output. The device lacks triple-voltage, watchdog, power-fail, or adjustable-threshold functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Range | 0.8V to 5.5V - powers device and enables valid reset assertion down to 0.8V |
| VCC2 Range | 0.8V to 5.5V - secondary supply monitor input; reset asserted if below threshold |
| Reset Threshold VTH1 | 4.500V to 4.750V (falling) - factory-trimmed for primary rail; suffix 'Y' denotes 4.625V nominal |
| Reset Threshold VTH2 | 2.550V to 2.700V (falling) - factory-trimmed for secondary rail; suffix 'H' denotes 2.625V nominal |
| Reset Timeout Period | 140ms (min) - fixed duration; ensures µP remains held in reset long enough for full power stabilization |
| Supply Current ICC | 15µA (typ) at 3.6V - ultra-low quiescent current enables use in always-on battery systems |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
MAX6715AUTYHD3+T is housed in a 5-pin SOT23 package (package code U5+1), with 0.95mm pitch, 2.9mm × 1.6mm footprint, and JEDEC MS-012AC outline. Thermal resistance θJA = 324.3°C/W (four-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST | Active-Low Reset Output | Open-drain output referenced to VCC1; requires external pullup; asserts low on VCC1/VCC2 undervoltage |
| 2 - GND | Ground Reference | Common return path for all internal comparators, timer, and output driver |
| 3 - MR | Active-Low Manual-Reset Input | Internal 50kΩ pullup to VCC1; logic-low pulse ≥1µs forces reset for full 140ms timeout |
| 4 - VCC2 | Secondary Supply Input | Powers internal VCC2 comparator; monitored against factory-trimmed 2.625V threshold |
| 5 - VCC1 | Primary Supply Input | Main power rail input; powers device core and RST output driver; monitored against 4.625V threshold |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply monitoring | Simultaneous VCC1 and VCC2 supervision with separate thresholds avoids single-point failure in multirail systems |
| Guaranteed reset validity to 0.8V | Ensures deterministic reset assertion even during deep brownout - critical for fail-safe shutdown in industrial PLCs |
| Immunity to short VCC transients | Rejects <20µs glitches below threshold, preventing spurious resets in noisy power environments |
| Low 15µA supply current | Enables integration into energy-constrained applications like remote sensors without compromising battery life |
| SOT23-5 compact footprint | Reduces PCB area by >60% vs. discrete supervisor solutions while maintaining full dual-rail functionality |
Applications
| Telecom Power Sequencing | Industrial PLC Control |
|---|---|
Use Scenario: Sequencing startup of FPGA, DSP, and analog front-end rails in 4G/5G base station power modules. IC Role / Device Role / Timing Role: Dual-supply supervisor enforcing strict VCC1 > 4.625V and VCC2 > 2.625V before releasing reset to enable synchronized boot. Use Value: Prevents configuration lockup due to out-of-spec rail sequencing; eliminates need for external timing RC networks. | Use Scenario: Monitoring main 24V DC input and isolated 3.3V logic supply in programmable logic controller I/O modules. IC Role / Device Role / Timing Role: Asserting fail-safe reset within 140ms of either supply dropping below threshold during field-induced transients. Use Value: Guarantees deterministic controller halt before corrupted I/O state propagates to field actuators. |
| Battery-Backed Data Logger | Automotive Infotainment Core |
Use Scenario: Supervising main Li-ion 3.7V rail and backup supercapacitor 2.5V rail in environmental data loggers deployed for months unattended. IC Role / Device Role / Timing Role: Detecting end-of-life voltage sag on both rails and triggering controlled shutdown via MR-initiated reset before data corruption. Use Value: 15µA ICC extends usable battery life beyond 5 years; 0.8V reset validity captures final brownout phase. | Use Scenario: Monitoring 5V system rail and 1.2V SoC core supply in head-unit infotainment systems operating in under-dash temperature extremes. IC Role / Device Role / Timing Role: Providing AEC-Q100-aligned supervision (via family qualification) with guaranteed operation from -40°C to +125°C junction. Use Value: Eliminates need for separate thermal derating design; supports ASIL-B functional safety architecture via deterministic reset behavior. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6716AUTYHD3+T | Push-pull RST output instead of open-drain; same thresholds, timeout, and pinout | Requires no external pullup; unsuitable for wired-OR reset buses or bidirectional µP reset pins | Select when driving single-load reset lines directly and minimizing BOM count |
| TPS3808G33DBVR | Single-supply (3.3V only), 200ms timeout, 2.5µA ICC, SOT23-6 package | Lacks VCC2 monitoring; cannot replace dual-rail supervision without redesign | Consider only for cost-sensitive single-rail applications where VCC2 supervision is omitted |
Compared with MAX6716AUTYHD3+T, the MAX6715AUTYHD3+T's open-drain RST enables shared reset bus architectures; versus TPS3808G33DBVR, it provides true dual-rail fault detection essential for systems with independent I/O and core supplies.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6715AUTYHD3+T?
The MAX6715AUTYHD3+T has a factory-trimmed VCC1 reset threshold of 4.625V (nominal), with guaranteed range 4.500V to 4.750V (falling). This value is encoded in the 'Y' suffix per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to this part number - not inferred from family data.
Does MAX6715AUTYHD3+T support watchdog timer functionality?
No, MAX6715AUTYHD3+T does not include watchdog functionality. Its ordering suffix 'TYHD3' and SOT23-5 pinout confirm absence of WDI pin. Watchdog capability is only present in variants with 'W' or '2' in the suffix (e.g., MAX6721A) and 6- or 8-pin packages.
Can MAX6715AUTYHD3+T monitor a third voltage rail such as RSTIN or PFI?
No, MAX6715AUTYHD3+T lacks RSTIN, PFI, PFO, and WDI pins - confirmed by its 5-pin SOT23 configuration and 'TYHD3' suffix. Triple-voltage monitoring requires variants like MAX6719A (6-pin) or MAX6727A (8-pin) with corresponding suffixes.
What is the maximum load current the RST output of MAX6715AUTYHD3+T can sink?
The open-drain RST output of MAX6715AUTYHD3+T guarantees VOL ≤ 0.3V at ISINK = 1.2mA (VCC1 ≥ 2.7V) and ≤ 0.4V at ISINK = 3.2mA (VCC1 ≥ 4.5V). Designers must select an external pullup resistor that limits current to within these specs for reliable logic-low assertion.
Is MAX6715AUTYHD3+T qualified for automotive applications?
While MAX6715AUTYHD3+T itself is not individually AEC-Q100 certified, it belongs to the MAX6715A–MAX6729A family in which specific variants (e.g., MAX6719AUTTWD1/V+T) are AEC-Q100 qualified. Its -40°C to +125°C operating range and robust transient immunity support automotive under-hood use where full qualification is not mandated.
