Product details
Overview
MAX6715UTSVD3 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 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 board management.
For engineers reviewing the MAX6715UTSVD3 datasheet, MAX6715UTSVD3 pinout, MAX6715UTSVD3 application, or MAX6715UTSVD3 equivalent, this page delivers verified electrical specs, exact pin functions, dual-supply monitoring context, and validated alternative options for multivoltage system design.
Technical Context
The MAX6715UTSVD3 integrates two independent voltage comparators with factory-trimmed thresholds (VTH1 = 4.625V, VTH2 = 3.075V), a 210ms 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 features an internal 50kΩ pullup on MR, supports manual reset pulse widths ≥1µs, and guarantees correct reset logic state with VCC1 or VCC2 ≥ 0.8V - enabling reliable brownout detection in low-voltage embedded systems without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 4.625V (factory-trimmed, ±125mV tolerance) - sets precise power-good detection for 5V or 4.8V primary rails |
| VCC2 Threshold | 3.075V (factory-trimmed, ±75mV tolerance) - enables accurate monitoring of 3.3V secondary supplies |
| Reset Timeout | 210ms (minimum) - ensures sufficient hold time for CPU initialization and peripheral stabilization |
| Supply Current | 14µA typical at 3.6V - minimizes quiescent load in battery-backed or always-on subsystems |
| 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 pins |
| MR Input Logic | Active-low with 50kΩ internal pullup to VCC1 - simplifies manual reset switch interface with no external components |
Pinout & Package
MAX6715UTSVD3 is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant, with gull-wing leads and thermal pad option per ordering code.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output referenced to VCC1; sinks up to 3.2mA at VCC1 ≥ 4.5V |
| 2 | GND | Analog/digital ground reference for all internal comparators and timers |
| 3 | MR | Active-low manual reset input with internal 50kΩ pullup to VCC1; accepts TTL/CMOS levels |
| 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 - internally unconnected; must be left floating or tied to GND per layout guidelines |
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 validity at low VCC | Outputs remain functional and logic-correct even when VCC1 or VCC2 drops to 0.8V - critical for brownout resilience |
| Immunity to short VCC transients | Rejects negative-going glitches <20µs wide at 100mV overdrive - prevents spurious resets during switching noise |
| Low-power operation | 14µA typical ICC at 3.6V - enables use in always-on monitoring circuits without impacting system efficiency |
| Integrated manual reset | MR pin with internal 50kΩ pullup eliminates external resistor; supports momentary switch interface with no debounce needed |
Applications
| Telecom Power Sequencing | Server Board Management |
|---|---|
Use Scenario: Monitoring 48V-derived 5V and 3.3V rails in line-card power modules during hot-swap insertion. IC Role / Device Role / Timing Role: Dual-supply supervisor asserting synchronized reset to FPGA and baseband processor upon undervoltage. Use Value: Prevents partial configuration and latch-up by enforcing strict power-rail ordering and 210ms hold time before release. |
Use Scenario: Ensuring clean boot of dual-core x86 processors on motherboard after AC power restoration. IC Role / Device Role / Timing Role: Primary supervisory IC validating both core (VCC1) and I/O (VCC2) supply stability before releasing reset to CPU. Use Value: Eliminates need for discrete RC reset circuits; factory-trimmed thresholds guarantee ±0.5% accuracy across temperature. |
| Industrial PLC Controller | Network Switch ASIC Power-Up |
Use Scenario: Supervising 24V-to-5V and 5V-to-3.3V DC/DC outputs in programmable logic controller backplane. IC Role / Device Role / Timing Role: Fault-detection node triggering watchdog-initiated recovery when either rail dips below specification. Use Value: Push-pull RST output drives reset directly into ARM Cortex-M7 without level-shifting or pullup resistors. |
Use Scenario: Coordinating power-up sequence of multi-rail ASIC (1.2V core, 2.5V I/O, 3.3V aux) in 10G Ethernet switch. IC Role / Device Role / Timing Role: Dual-threshold monitor ensuring 3.3V auxiliary rail stabilizes before enabling 1.2V core regulator via enable signal. Use Value: Factory-trimmed VTH1/VTH2 eliminates calibration overhead and reduces BOM count versus discrete solutions. |
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 VTH1/VTH2 (4.625V/3.075V) and 210ms timeout, but open-drain RST output instead of push-pull | Requires external pullup resistor; suitable where reset bus sharing or wired-OR logic is needed | Select MAX6716UTLTD3-T only if system requires open-drain reset signaling - otherwise MAX6715UTSVD3 offers simpler direct-drive interface |
| TPS3808G33DBVR | Single-supply supervisor (3.3V threshold only), 200ms timeout, 2.5µA supply current, SOT23-6 package | Lacks VCC2 monitoring capability; cannot replace dual-rail supervision without adding second IC | Choose TPS3808G33DBVR only for single-rail 3.3V systems; MAX6715UTSVD3 remains necessary where concurrent VCC1/VCC2 validation is required |
Compared with MAX6716UTLTD3-T and TPS3808G33DBVR, the MAX6715UTSVD3 uniquely provides factory-trimmed dual-threshold supervision with push-pull output in one SOT23-6 device - reducing PCB area, eliminating external components, and simplifying firmware reset handling.

FAQ
What is the exact reset threshold voltage for VCC1 on MAX6715UTSVD3?
The MAX6715UTSVD3 has a factory-trimmed VCC1 reset threshold of 4.625V (typical), with guaranteed limits of 4.500V (min) and 4.750V (max) over temperature. This value is encoded in the "TS" suffix per Maxim's Reset Voltage Threshold Suffix Guide and applies specifically to the MAX6715UTSVD3 - not the broader MAX6715 family.
Does MAX6715UTSVD3 support monitoring a third voltage rail?
No, MAX6715UTSVD3 is a dual-voltage supervisor and does not include RSTIN or PFI inputs. Only MAX6719/MAX6720/MAX6723–MAX6729 variants in the family support triple-voltage monitoring. The MAX6715UTSVD3 monitors only VCC1 and VCC2, with no provision for auxiliary voltage inputs.
What is the function of Pin 6 on MAX6715UTSVD3?
Pin 6 on MAX6715UTSVD3 is NC (no connect) - it is internally unconnected and must be left floating or tied to GND per Maxim's layout recommendations. It is not used for reset, manual reset, or any other signal; connecting it to VCC or other signals may cause undefined behavior.
Can MAX6715UTSVD3 operate with VCC1 = 1.8V?
Yes, MAX6715UTSVD3 supports VCC1 as low as 1.8V per datasheet specifications, but its 4.625V VCC1 threshold means it will assert reset continuously at 1.8V. For proper operation, VCC1 must meet or exceed the threshold (≥4.500V min). The 1.8V lower limit refers to functional operation of internal circuitry - not valid supervision range.
Is the reset timeout period of MAX6715UTSVD3 adjustable?
No, the reset timeout period of MAX6715UTSVD3 is fixed at 210ms (minimum) as indicated by the "D3" suffix in the part number. Timeout values are factory-set and non-adjustable; alternatives like D1 (1.1ms), D2 (8.8ms), or D5 (280ms) require different orderable part numbers.
