Product details
Overview
MAX6759UTTD3+T from Analog Devices is a single-supply, low-power window voltage detector with factory-trimmed 3.3V nominal monitoring, ±10% threshold window (3.0V–3.63V), 100ms minimum reset timeout, active-low open-drain UV and OV outputs, and manual reset input - used in telecom power rails to prevent microprocessor malfunction during brownout or overvoltage events.
For engineers reviewing the MAX6759UTTD3+T datasheet, MAX6759UTTD3+T pinout, MAX6759UTTD3+T application, or MAX6759UTTD3+T equivalent, key selection criteria include undervoltage/overvoltage threshold accuracy over -40°C to +125°C, 10μA supply current at 3.6V, SOT23-6 package footprint compatibility, and open-drain output drive capability for wired-OR reset signaling.
Technical Context
The MAX6759UTTD3+T implements dual independent comparators with internal reference and hysteresis (0.7%) to detect VCC falling below UVTH (2.97V min) or rising above OVTH (3.63V max) under temperature extremes. Its SET pin is tied to VCC to configure the ±10% window, and MR enables system-initiated reset assertion with 300ns propagation delay.
It features no OV latch function (distinguishing it from MAX6760–MAX6762), uses only VCC as both supply and monitored rail, and provides separate UV and OV outputs without combined RESET - requiring external logic if single reset signal is needed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VCC | 3.3V - factory-trimmed detection point for standard I/O supply rails |
| UV Threshold Range | 2.97V–3.135V at TA = -40°C to +125°C - ensures reliable brownout detection across automotive/industrial temp range |
| OV Threshold Range | 3.63V–3.795V at TA = -40°C to +125°C - guards against overvoltage damage to 3.3V logic |
| Timeout Period | 100ms min - guarantees sustained reset hold-off after VCC recovery, preventing premature MCU restart |
| Supply Current | 13µA typ at 3.6V - enables always-on monitoring in battery-backed or low-power systems |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive, industrial control, and telecom base station use |
| Output Type | Open-drain UV and OV - supports flexible pull-up voltage (up to 6.5V) and wired-OR reset bus sharing |
Pinout & Package
MAX6759UTTD3+T is housed in a 6-pin SOT23 package (package code U6+1, outline 21-0058), with exposed pad not present. Pin functions are validated per MAX6759 functional diagram and pin description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal comparators and bias circuits |
| 2 | UV | Active-low open-drain undervoltage output - asserts when VCC < UVTH |
| 3 | MR | Active-low manual reset input - internally pulled up to VCC via 26kΩ; 4µs min pulse width |
| 4 | SET | Threshold window select - tied to VCC for ±10% window (3.3V ±0.33V) |
| 5 | OV | Active-low open-drain overvoltage output - asserts when VCC > OVTH; no timeout |
| 6 | VCC | Power supply and monitored voltage input - operates from 1.0V to 6.0V; outputs valid down to 1.0V |
Key Features
| Feature | Design Value |
|---|---|
| Separate UV/OV outputs | Enables independent fault reporting and selective system response (e.g., log OV event while holding UV reset) |
| ±10% factory-set window | Eliminates external resistor networks for 3.3V rail monitoring - reduces BOM count and layout area |
| 100ms minimum timeout | Prevents oscillatory reset during slow VCC ramp-up or noisy supply recovery |
| 10μA supply current | Supports continuous monitoring in energy-constrained applications like remote sensors or backup power domains |
| Manual reset input | Allows host processor or push-button to force system reset regardless of VCC status |
Applications
| Telecom Power Supervision | Industrial PLC I/O Module |
|---|---|
Use Scenario: Monitoring 3.3V auxiliary supply in LTE baseband unit during AC mains fluctuation or battery switchover. IC Role / Device Role / Timing Role: Window detector asserting UV/OV flags to FPGA for graceful shutdown or alarm logging. Use Value: Prevents corrupted data writes or state corruption by ensuring CPU remains held in reset until stable 3.3V is confirmed. | Use Scenario: Supervising isolated 3.3V digital I/O supply in modular PLC backplane where EMI causes transient excursions. IC Role / Device Role / Timing Role: Independent UV and OV outputs feed separate watchdog timers for redundant fault handling. Use Value: Enables differentiated response - OV triggers immediate power disconnect, while UV initiates controlled I/O disable sequence. |
| Automotive ADAS Camera Module | Server BMC Power Sequencing |
Use Scenario: Validating 3.3V image sensor interface supply in rear-view camera exposed to cold cranking (<6V) and load dump (>16V). IC Role / Device Role / Timing Role: UV output holds image pipeline in reset during cranking; OV output disables sensor on load dump detection. Use Value: Meets AEC-Q100 Grade 0 temp range (-40°C to +125°C) and rejects 300ns transients per spec. | Use Scenario: Coordinating reset timing between BMC and main SoC during 3.3V rail power-up in 1U server. IC Role / Device Role / Timing Role: Separate UV/OV outputs feed BMC GPIOs to validate rail stability before releasing SoC reset. Use Value: Eliminates need for external RC timing network - 100ms timeout ensures rail settles before boot initiation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar window voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6758UTTD3+T | Active-high push-pull UV output instead of open-drain; same thresholds, timeout, and pinout | Requires direct connection to MCU input without external pull-up; incompatible with wired-OR buses | Select when interfacing with voltage-tolerant inputs needing active-high assertion and no shared reset line |
| TLV809E33DBZR | Single-output (reset only), ±2% accuracy, no SET pin, 200ms timeout, SOT23-3 package | Lacks independent OV reporting and adjustable window; smaller footprint but reduced diagnostic granularity | Select when only basic reset generation is required and board space is constrained |
Compared with MAX6758UTTD3+T and TLV809E33DBZR, the MAX6759UTTD3+T uniquely delivers open-drain UV/OV outputs in SOT23-6 for fault-isolated signaling, ±10% window configurability via SET, and guaranteed operation down to 1.0V VCC - making it optimal for diagnostics-rich, multi-rail supervision where output flexibility and low-voltage validity matter.

FAQ
What is the exact undervoltage and overvoltage threshold range for MAX6759UTTD3+T at -40°C to +125°C?
The MAX6759UTTD3+T has a guaranteed UV threshold range of 2.97V to 3.135V and OV threshold range of 3.63V to 3.795V across the full -40°C to +125°C operating temperature range, based on factory trimming for 3.3V nominal with ±10% window and SET tied to VCC. These values are specified in the Electrical Characteristics table under UVTH and OVTH conditions for T-suffix (3.3V) and D3 timeout option.
Does MAX6759UTTD3+T support dual-voltage monitoring like MAX6760 series?
No, MAX6759UTTD3+T monitors only a single voltage (VCC) and does not support dual-rail supervision. It lacks VCC2 input and associated circuitry found in MAX6760–MAX6762. The MAX6759UTTD3+T is strictly a single-supply window detector with UV and OV outputs derived solely from the VCC pin.
Can the timeout period of MAX6759UTTD3+T be adjusted externally?
No, the timeout period of MAX6759UTTD3+T is fixed at 100ms minimum (D3 suffix) and cannot be adjusted externally. It is implemented via internal capacitor-based timing and is not user-programmable. For adjustable timeout, consider the MAX6763/MAX6764 with external RC configuration.
What is the maximum sink current capability of the UV and OV outputs on MAX6759UTTD3+T?
The UV and OV outputs of MAX6759UTTD3+T are open-drain and specified to sink up to 1.4mA at VCC ≥ 1.98V while maintaining VOL ≤ 0.3V. At higher VCC levels (≥2.75V, ≥3.63V, ≥5.5V), sink capability increases to 2.0mA, 3.0mA, and 4.0mA respectively - enabling direct interface with standard logic inputs or optocouplers without additional buffering.
Is MAX6759UTTD3+T AEC-Q100 qualified for automotive applications?
No, MAX6759UTTD3+T is not AEC-Q100 qualified. Only /V-suffixed variants (e.g., MAX6759UTTD3/V) in specific packages are AEC-Q100 qualified. The +T suffix indicates tape-and-reel packaging but does not imply automotive qualification. For automotive use, verify ordering code includes /V and consult the official Analog Devices automotive product list.
