Product details
Overview
MAX6519UKP095-T from Maxim Integrated is an active-low, open-drain temperature switch with factory-programmed +95°C hot-threshold trip point, ±1.5°C max accuracy over -15°C to +65°C, 22µA typical supply current, and pin-selectable 2°C/10°C hysteresis - used for overtemperature protection in fan control and server thermal management.
For engineers reviewing the MAX6519UKP095-T datasheet, MAX6519UKP095-T pinout, MAX6519UKP095-T application, or MAX6519UKP095-T equivalent, key selection criteria include its open-drain output configuration, SOT23-5 package, analog output capability for board-level testing, and compatibility with pull-up voltages up to 5.5V independent of VCC.
Technical Context
The MAX6519UKP095-T integrates a BiCMOS analog temperature sensor, fixed voltage reference, and comparator to detect die temperature crossing +95°C. Its TOVER output asserts low when temperature exceeds threshold, while OUT provides a linear analog voltage (0.77V–2.59V) proportional to die temperature across -45°C to +125°C.
Hysteresis is selected via HYST pin: tied to VCC for 2°C, or GND for 10°C - preventing output oscillation near trip point. The device operates from 2.7V to 5.5V; for full -45°C to +125°C range operation, VCC > 4.5V is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - supports standard logic rails and battery-backed systems without external regulation |
| Temperature Threshold | +95°C hot threshold - factory-trimmed and stable; triggers TOVER low on overtemperature event |
| Accuracy | ±1.5°C max over -15°C to +65°C - ensures reliable trip timing in ambient-compliant computing environments |
| Supply Current | 22µA typical - enables always-on thermal monitoring in power-constrained embedded systems |
| Hysteresis Options | 2°C (HYST = VCC) or 10°C (HYST = GND) - selectable per PCB layout to prevent chatter during thermal transients |
| Analog Output Range | 0.77V to 2.59V over -45°C to +125°C - allows post-assembly calibration and functional verification via ADC |
| Output Type | Active-low, open-drain TOVER - supports wired-OR alarm aggregation and level-shifting with external pull-up |
Pinout & Package
MAX6519UKP095-T is housed in a 5-pin SOT23 package (U5+2 outline), with 1.6mm × 2.9mm footprint and 1.1mm height - optimized for space-constrained PCBs in servers and notebooks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Analog temperature output | Provides voltage proportional to die temperature (0.77V–2.59V); enables board-level test and diagnostics |
| 2 - GND | Ground reference | Primary thermal path and signal return; lowest thermal resistance to die (pin 2 critical for accurate sensing) |
| 3 - HYST | Hysteresis select input | Logic-high (VCC) selects 2°C hysteresis; logic-low (GND) selects 10°C - no external components needed |
| 4 - VCC | Power supply input | 2.7V–5.5V operation; requires 0.1µF bypass capacitor to GND for noise immunity |
| 5 - TOVER | Open-drain overtemperature output | Asserts low when T ≥ +95°C; requires external 100kΩ pull-up; supports pull-up voltage up to 5.5V (independent of VCC) |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed +95°C trip point | Eliminates need for external resistors or calibration; guarantees threshold accuracy without user trimming |
| Pin-selectable hysteresis | Enables system-specific noise immunity tuning (2°C for precision, 10°C for noisy thermal environments) |
| Integrated analog output (OUT) | Supports production-line functional test and field diagnostics without additional sensors or circuitry |
| Open-drain TOVER with level-shift capability | Allows alarm signaling to higher-voltage logic domains (e.g., 3.3V MCU monitoring 5V rail) |
| Low 22µA quiescent current | Permits continuous thermal supervision in battery-powered or energy-harvesting applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar temperature switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6517UKP095-T | Same SOT23-5 package, identical +95°C hot threshold and open-drain output, but lacks analog OUT pin (pin 1 unconnected) | No board-level analog test capability; suitable only for pure digital alarm use cases | Select MAX6517UKP095-T when analog diagnostics are unnecessary and BOM cost reduction is prioritized |
| LM20BIM7X/NOPB | Temperature sensor only (no switch output); analog output only; ±2.5°C accuracy; no hysteresis or digital alarm function | Requires external comparator and logic to implement overtemperature detection; adds design complexity | Choose LM20BIM7X/NOPB only when flexible threshold programming is required and system already includes comparator resources |

FAQ
What is the exact temperature trip point of the MAX6519UKP095-T?
The MAX6519UKP095-T has a factory-programmed hot-threshold trip point of +95°C. This value is trimmed during manufacturing and specified with ±1.5°C maximum accuracy over the -15°C to +65°C range. The device asserts its open-drain TOVER output low when die temperature reaches or exceeds this threshold.
Does the MAX6519UKP095-T require external components to operate?
No, the MAX6519UKP095-T requires no external components for basic operation. It integrates a temperature sensor, reference, and comparator. Only a 0.1µF bypass capacitor on VCC is recommended for noise immunity, and a 100kΩ pull-up resistor on TOVER is required for proper open-drain logic level translation.
Can the MAX6519UKP095-T be used to monitor temperatures below 0°C?
Yes, the MAX6519UKP095-T operates from -55°C to +125°C. However, for reliable operation down to -45°C, the supply voltage must exceed 4.5V. At lower VCC (e.g., 2.7V–4.5V), the guaranteed operating range is -35°C to +125°C per the datasheet specifications.
How does hysteresis work on the MAX6519UKP095-T, and how is it configured?
Hysteresis on the MAX6519UKP095-T is configured by connecting the HYST pin: to VCC for 2°C hysteresis, or to GND for 10°C hysteresis. This prevents output oscillation when temperature hovers near the +95°C trip point. The hysteresis is implemented internally and requires no external circuitry.
What is the function of the OUT pin on the MAX6519UKP095-T?
The OUT pin on the MAX6519UKP095-T provides an analog voltage proportional to die temperature (0.77V–2.59V over -45°C to +125°C). It enables board-level functional testing, calibration verification, and real-time temperature monitoring without requiring a separate sensor - supporting production test and field diagnostics.
