Thermal Management datasheet and documents for MAX6641AUB94+
Thermal Management Overview
The MAX6641AUB94+ is a temperature sensor and fan controller in a 10-pin µMAX package. It measures local die and remote pn junction temperatures, reporting data via an SMBus interface. The device features a PWM output for automatic fan speed control and an over-temperature alarm. Operating from 3.0V to 5.5V, it supports -40°C to +125°C automotive range with ±1°C remote accuracy between +60°C and +145°C.
Thermal Management Feature Summary
- SMBus-compatible digital interface for reading temperature data and programming alarm thresholds
- Automatic PWM fan-speed controller with programmable characteristics and automatic spin-up
- Over-temperature alarm output for generating interrupts, throttle signals, or shutdowns
- Temperature monitoring begins at power-on for fail-safe system protection

Thermal Management Procurement Notes
Verify the component matches the specific Maxim Integrated part number MAX6641AUB94+. Confirm the 10-pin µMAX package and automotive temperature rating. Ensure the ordering suffix corresponds to the correct SMBus address configuration as defined in the manufacturer's documentation.
Thermal Management Selection Notes
Select this component when SMBus connectivity is required for thermal management. It is suitable for applications needing precise remote diode temperature measurement alongside integrated fan control. Consider the slim package profile and low supply current consumption for space-constrained designs.
Thermal Management Part Context
This device belongs to the MAX6641 family of SMBus-compatible temperature monitors. It integrates both local and remote temperature sensing capabilities with hardware-based fan control logic. The family offers multiple SMBus addresses to allow multiple devices on a single bus.
Thermal Management Replacement Considerations
Check the MAX6641AUB90+, MAX6641AUB92+, and MAX6641AUB96+ datasheets for identical functionality with different SMBus slave addresses. Verify pin compatibility and register mapping before substitution.
