Product details
Overview
MAX6715UTYHD3 from Maxim Integrated is a dual-voltage microprocessor supervisory circuit in SOT23-6 package, monitoring VCC1 (4.625V threshold) and VCC2 (3.075V threshold) with 210ms 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 board management.
For engineers reviewing the MAX6715UTYHD3 datasheet, MAX6715UTYHD3 pinout, MAX6715UTYHD3 application, or MAX6715UTYHD3 equivalent, this page delivers verified electrical specs, exact pin functions, dual-supply monitoring context, reset timing behavior, and validated alternative options for multivoltage system design.
Technical Context
The MAX6715UTYHD3 implements independent voltage comparators for primary (VCC1) and secondary (VCC2) supplies, each with factory-trimmed thresholds (4.625V and 3.075V), hysteresis of 0.5%, and temperature coefficient of 20ppm/°C. It asserts reset when either supply falls below its threshold and holds reset for 210ms (min) after both recover.
It features a push-pull RST output referenced to VCC1, internal 50kΩ MR pullup, and immunity to VCC transients ≤20µs at 100mV overdrive. Supply current is 14µA (typ) at 3.6V, and operation is guaranteed from -40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed falling threshold; enables reliable reset assertion for 5V rail brownout detection) |
| VCC2 Threshold | 3.075V (factory-trimmed falling threshold; supports precise monitoring of 3.3V I/O or core supply) |
| Reset Timeout | 210ms (minimum duration; ensures µP completes boot sequence before releasing reset) |
| Supply Current | 14µA typical at 3.6V (ultra-low quiescent draw; critical for battery-backed or always-on systems) |
| Operating Temp | -40°C to +85°C (industrial-grade range; suitable for telecom equipment and embedded servers) |
| Reset Output Type | Push-pull active-low (no external pullup required; drives directly into µP reset pin with defined VOH/VOL) |
| MR Input | Active-low with 50kΩ internal pullup to VCC1 (enables momentary switch interface without external components) |
Pinout & Package
MAX6715UTYHD3 is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with thermal pad option not included. Pin 1 is marked by dot; device orientation follows JEDEC MO-178AB standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; sinks up to 3.2mA at VCC1 ≥ 4.5V; VOH = 0.8×VCC1 |
| 2 | GND | Analog/digital ground reference; must be connected to system ground plane for stable comparator operation |
| 3 | MR | Active-low manual reset input; internally pulled up to VCC1 (50kΩ); accepts TTL/CMOS logic; 1µs minimum pulse width |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V range); powers internal VCC2 comparator and sets RST2 reference if enabled |
| 5 | VCC1 | Primary supply input (1.8V–5.0V range); powers device core, sets RST output reference, and enables VCC1 comparator |
| 6 | NC | No connect; left unconnected per datasheet; no internal connection or function |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 (4.625V) and VCC2 (3.075V) supervision with separate comparators and hysteresis - eliminates need for two discrete supervisors |
| Guaranteed reset validity down to 0.8V | Ensures correct RST logic state even during deep brownout (VCC1 or VCC2 ≥ 0.8V), enabling fail-safe behavior in low-voltage recovery scenarios |
| 210ms min reset timeout | Provides deterministic hold time for µP initialization; avoids premature release due to supply ripple or slow-rising rails |
| Push-pull RST output | Eliminates external pullup resistor requirement; reduces BOM count and PCB area vs. open-drain alternatives |
| Internal MR pullup (50kΩ) | Supports direct connection of momentary switch to GND without external biasing; simplifies front-panel reset implementation |
Applications
| Telecom Power Sequencing | Server Baseboard Management |
|---|---|
Use Scenario: Monitoring 48V-derived 5V and 3.3V rails in line-card power modules where sequential turn-on and fault isolation are required. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting reset if either rail drops during hot-swap or transient events; 210ms timeout aligns with FPGA configuration window. Use Value: Prevents corrupted firmware load by holding reset until both rails stabilize post-insertion, improving field reliability. |
Use Scenario: Ensuring clean boot of BMC (Baseboard Management Controller) on x86 server motherboards with split 5V/3.3V/1.8V domains. IC Role / Device Role / Timing Role: Primary supervisor for main 5V and auxiliary 3.3V supplies; RST output tied to BMC reset pin; MR supports IPMI-triggered hard reset. Use Value: Guarantees BMC enters known state before SPI flash access, eliminating boot hangs caused by marginal VCC2. |
| Industrial PLC I/O Module | Network Switch ASIC Power-Up |
Use Scenario: Supervising isolated 5V logic and 3.3V sensor interface supplies in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Dual-threshold monitor detecting undervoltage on either domain; push-pull RST drives optocoupled reset chain to CPU and FPGA. Use Value: Maintains reset assertion during 100ms AC line dips, preventing spurious I/O state changes during factory automation cycles. |
Use Scenario: Coordinating power-up of multi-rail ASIC (5V analog, 3.3V I/O, 1.2V core) in 10G Ethernet switches with strict sequencing requirements. IC Role / Device Role / Timing Role: Secondary supervisor verifying 5V and 3.3V rails before enabling DC/DC for 1.2V core; RST output gates enable signal to core regulator. Use Value: Enforces minimum 210ms delay between I/O rail stabilization and core enable, avoiding ASIC latch-up during ramp-up. |
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, identical 4.625V/3.075V thresholds and 210ms timeout, but open-drain RST output requiring external pullup | Suitable where level-shifting or wired-OR reset bus is needed; incompatible with direct µP reset pin drive without pullup | Select MAX6716UTLTD3-T only if system requires open-drain reset for bus sharing or voltage translation. |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only), 200ms timeout, SOT23-6, 1.8µA supply current; lacks VCC2 monitoring and MR pullup | Applicable only for single-rail systems; cannot replace dual-monitoring function without adding second IC | Choose TPS3808G33DBVR only for cost-sensitive, single-supply designs where VCC2 supervision is unnecessary. |
Compared with MAX6715UTYHD3, MAX6716UTLTD3-T offers identical voltage thresholds and timing but requires external pullup for reset assertion, while TPS3808G33DBVR reduces supply current by 87% yet sacrifices dual-supply capability and manual reset integration - making MAX6715UTYHD3 optimal for compact, self-contained dual-rail supervision.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on MAX6715UTYHD3?
The MAX6715UTYHD3 has factory-trimmed reset thresholds of 4.625V for VCC1 (primary supply) and 3.075V for VCC2 (secondary supply), as indicated by the 'YT' suffix per Maxim's Reset Voltage Threshold Suffix Guide. These values are specified at TA = +25°C with ±1.5% tolerance over temperature and load, and include 0.5% hysteresis to prevent chatter during threshold crossing.
Does MAX6715UTYHD3 support manual reset, and how is it implemented?
Yes, MAX6715UTYHD3 includes an active-low manual reset (MR) input on Pin 3 with an internal 50kΩ pullup resistor to VCC1. Pulling MR low for ≥1µs forces reset assertion for the full 210ms timeout period, even if supplies remain valid. The input accepts TTL/CMOS logic levels and supports direct connection of a momentary switch to GND without external components.
What is the reset output type and drive capability of MAX6715UTYHD3?
MAX6715UTYHD3 features a push-pull active-low RST output on Pin 1, referenced to VCC1. It sources up to 800µA (VOH ≥ 0.8×VCC1) and sinks up to 3.2mA (VOL ≤ 0.4V at VCC1 ≥ 4.5V). This eliminates the need for an external pullup resistor and allows direct interfacing with µP reset pins requiring defined high/low states.
Is MAX6715UTYHD3 compatible with systems operating below 1.0V on either supply rail?
No - MAX6715UTYHD3 guarantees correct reset output logic state only when VCC1 or VCC2 remains ≥ 0.8V. Below 0.8V, reset behavior is not specified. For sub-0.8V operation, external pull-down (for open-drain variants) or alternate supervision architecture is required. The device itself does not operate or assert valid reset below 0.8V.
How does the 210ms reset timeout period of MAX6715UTYHD3 affect system boot timing?
The 210ms minimum timeout ensures the MAX6715UTYHD3 holds RST low for at least that duration after all monitored supplies exceed their thresholds, providing sufficient margin for slow-rising rails, FPGA configuration, or bootloader execution. This fixed delay is factory-set via the 'D3' suffix and is temperature-stable (±10% over -40°C to +85°C), preventing premature release during marginal conditions.
