What are the key features of LM41CIMT?
- ±1°C measurement accuracy over 0°C to +85°C range with serial digital output for direct microcontroller interfacing
- 3.6 V maximum supply voltage in a compact 14-pin TSSOP package enabling use in low-voltage 3.3 V digital systems
- Integrated temperature-to-digital conversion eliminates external signal conditioning, reducing BOM and PCB area
What is LM41CIMT used for?
LM41CIMT is designed for thermal management and over-temperature protection in computer motherboards, server blades, and telecom line cards operating in 0°C to 85°C environments. Its serial digital output connects directly to system management bus interfaces, enabling firmware to read die temperature and activate cooling fans or throttle clock frequencies when thresholds are exceeded. The compact TSSOP-14 footprint makes it suitable for high-density PCB designs where space is at a premium.

Frequently Asked Questions
Over what temperature range does LM41CIMT maintain its ±1°C accuracy, and is that sufficient for server thermal shutdown logic?
LM41CIMT maintains ±1°C accuracy across its full operating range of 0°C to +85°C, which covers typical server inlet air temperatures. This precision allows firmware to trigger cooling responses at a safe margin below the CPU's maximum junction temperature, providing reliable thermal shutdown without false triggers caused by sensor error.
What supply voltage range does LM41CIMT require, and can it operate alongside 3.3 V logic without a level shifter?
LM41CIMT operates from a supply voltage up to 3.6 V maximum, making it natively compatible with 3.3 V logic rails found in FPGAs, microcontrollers, and system-management controllers. No level shifter or voltage translation circuit is needed, simplifying the schematic and saving at least 2 passive components per channel.
For a high-density PCB with multiple thermal monitoring points, how does the TSSOP-14 package of LM41CIMT help minimize board real estate?
The TSSOP-14 package measures approximately 5 mm x 4.4 mm with 0.65 mm lead pitch, occupying roughly 22 mm² of board area. Placing three LM41CIMT sensors consumes under 70 mm² total, compared to bulkier SO-8 or PDIP packages, enabling thermal monitoring at CPU, VRM, and ambient locations within a compact blade-server module.
