Product details
Overview
MAX6502UKP095 from Maxim Integrated is a factory-programmed, hot-temperature threshold silicon temperature switch with active-high push-pull output, designed for overtemperature detection in thermal management systems. It operates from +2.7V to +5.5V, consumes 30µA typical supply current, features ±0.5°C typical threshold accuracy at +95°C trip point, and supports pin-selectable 2°C or 10°C hysteresis. It directly drives fan-control logic in embedded power systems.
For engineers reviewing the MAX6502UKP095 datasheet, MAX6502UKP095 pinout, MAX6502UKP095 application, or MAX6502UKP095 equivalent, this page delivers verified functional identity, SOT23-5 package mapping, confirmed +95°C trip point, push-pull output drive capability (VOH = VCC − 1.5V @ ISOURCE = 800µA), and validated alternatives for thermal monitoring in industrial and computing environments.
Technical Context
The MAX6502UKP095 integrates two on-die temperature-dependent voltage references-one with positive and one with negative temperature coefficient-to define its +95°C trip point. Its internal comparator triggers the push-pull output when die temperature exceeds this factory-trimmed threshold.
Hysteresis is selected via the HYST pin: grounded for 2°C, tied to VCC for 10°C-preventing output oscillation near threshold. The device includes an internal power-on reset circuit ensuring defined output state for 50µs at startup, and exhibits negligible self-heating (<0.042°C rise under 1mA sink load) due to 30µA quiescent current and 140°C/W θJA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Temperature Threshold | +95°C factory-programmed hot-trip point; asserts output high when die temperature exceeds +95°C. |
| Supply Voltage Range | +2.7V to +5.5V; enables direct interface with 3.3V and 5V logic domains without level-shifting. |
| Supply Current | 30µA typical; minimizes system power budget impact in battery-powered or energy-sensitive applications. |
| Output Type | Active-high push-pull; sources up to 800µA (VOH ≥ VCC − 1.5V) and sinks up to 3.2mA (VOL ≤ 0.4V), eliminating external pull-up resistors. |
| Threshold Accuracy | ±0.5°C typical over full operating range (−55°C to +125°C); ensures precise thermal event triggering without calibration. |
| Hysteresis Options | PIN-selectable: 2°C (HYST = GND) or 10°C (HYST = VCC); prevents chatter during slow thermal transitions. |
| Package | SOT23-5; compact 2.9mm × 1.6mm footprint with Pin 2 optimized for lowest thermal resistance to die. |
Pinout & Package
SOT23-5 package with exposed thermal pad not electrically connected; Pin 2 provides lowest thermal resistance path to die for accurate ambient sensing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | GND | Ground reference; both pins must be connected together near the IC; Pin 2 is thermally optimized for die-to-PCB heat transfer. |
| 3 | HYST | Hysteresis select input; CMOS-compatible; must be driven to GND (2°C hysteresis) or VCC (10°C hysteresis); floating state increases supply current. |
| 4 | VCC | Positive supply input; accepts +2.7V to +5.5V; powers internal references, comparator, and output stage. |
| 5 | TOVER | Active-high push-pull output; goes high when die temperature > +95°C; drives fan-enable logic or thermal interrupt directly. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed +95°C threshold | Eliminates need for external calibration components and reduces BOM count in thermal protection circuits. |
| Push-pull output architecture | Directly interfaces with fan controllers or logic inputs without pull-up resistors, simplifying PCB layout and reducing component cost. |
| Pin-selectable hysteresis | Enables system-level tuning of thermal response stability: 2°C for tight control, 10°C for noisy thermal environments. |
| 30µA supply current | Supports always-on thermal monitoring in low-power embedded systems without compromising battery life or standby efficiency. |
| ±0.5°C typical accuracy | Ensures consistent overtemperature response across production units and temperature ranges, critical for safety-critical shutdown functions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar temperature switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM75BIMM/NOPB | I²C digital output; requires microcontroller interface and firmware polling; ±2°C accuracy; no hysteresis pin. | Used where multi-zone monitoring or configurable thresholds are needed; unsuitable for direct logic-driven fan control. | Select when system already uses I²C bus and needs programmable thresholds; avoid when deterministic, zero-latency hardware trip is required. |
| TC74A0-5.0VAT | I²C interface; ±2°C accuracy; 2.7V–5.5V supply; no push-pull output; requires external pull-ups and host polling. | Deployed in distributed sensor networks with shared bus; lacks autonomous assertion capability of MAX6502UKP095. | Choose for cost-sensitive, multi-sensor deployments with existing I²C infrastructure; not a drop-in replacement for direct fan enable. |
Compared with LM75BIMM/NOPB and TC74A0-5.0VAT, the MAX6502UKP095 delivers autonomous, hardware-based overtemperature response with push-pull output-enabling immediate fan activation or shutdown without processor involvement, while offering superior ±0.5°C accuracy and pin-selectable hysteresis for robust thermal management.

FAQ
What is the exact temperature trip point of the MAX6502UKP095?
The MAX6502UKP095 has a factory-programmed hot-temperature threshold of +95°C. This means its push-pull output transitions high when the die temperature exceeds +95°C, and remains high until temperature falls below (+95°C − hysteresis). Hysteresis is selectable: 2°C if HYST is grounded, or 10°C if HYST is tied to VCC. The +95°C value is laser-trimmed during manufacturing and specified with ±0.5°C typical accuracy across −55°C to +125°C.
Does the MAX6502UKP095 require external components to operate?
No, the MAX6502UKP095 requires no external components for basic operation. Its push-pull output eliminates the need for pull-up resistors, and internal references and comparator are fully integrated. Only VCC decoupling (e.g., 0.1µF ceramic capacitor near Pin 4) and proper grounding of Pins 1 and 2 are recommended. The HYST pin must be actively driven to GND or VCC-floating is prohibited as it increases supply current.
Can the MAX6502UKP095 be used in a temperature window alarm configuration?
Yes, the MAX6502UKP095 can be paired with a cold-threshold device like MAX6504UKN005 to create a temperature window alarm. In such a setup, the MAX6502UKP095 asserts high above +95°C (overtemperature), while the cold device asserts high below its threshold (undertemperature). Their outputs can be ORed using discrete diodes or logic gates to generate a single "out-of-window" signal. This configuration is explicitly supported in Maxim's application diagrams (e.g., Figure 4).
What is the maximum output drive capability of the MAX6502UKP095?
The MAX6502UKP095 push-pull output can source up to 800µA while maintaining VOH ≥ VCC − 1.5V (at VCC > 4.5V), and sink up to 3.2mA while maintaining VOL ≤ 0.4V (at VCC > 4.5V). This allows direct driving of fan-enable inputs, logic gates, or optocoupler LEDs without buffer stages. Output resistance varies with temperature and supply voltage-typical source resistance is ~600Ω at +25°C and VCC = 5V.
Is the MAX6502UKP095 RoHS-compliant and lead-free?
Yes, the MAX6502UKP095 is RoHS-compliant and lead(Pb)-free, as indicated by the "+" suffix in its package code (UKP095+T). It meets JEDEC J-STD-020 reflow profile requirements with a peak soldering temperature of +260°C and is qualified for standard SMT assembly processes. The device is rated for operation from −55°C to +135°C and storage from −65°C to +165°C.
