Frequently Asked Questions
What does the LM87CIMT/NOPB monitor?
The LM87CIMT/NOPB monitors 7 analog voltage inputs, an on-chip temperature sensor plus one external temperature sensor, and up to 3 fan tachometer inputs. All readings are accessible via SMBus (I2C-compatible) interface and can trigger programmable alarm outputs.
What is the supply voltage range for the LM87CIMT/NOPB?
The LM87CIMT/NOPB operates from a 2.8V to 5.5V supply voltage, making it compatible with both 3.3V and 5V system designs. The TSSOP-16 package is well-suited for compact PCB layouts.
Is LM87CIMT/NOPB RoHS compliant?
Yes. The NOPB suffix indicates No Lead (Pb-Free), making the LM87CIMT/NOPB fully RoHS compliant. It is suitable for designs requiring lead-free components per EU RoHS and China RoHS regulations.
What are common alternatives to LM87CIMT/NOPB?
Functional alternatives include the Maxim MAX6650 (fan controller), the SMSC EMC6D103 (multi-channel system monitor), and TI LM80 (predecessor hardware monitor). Selection depends on channel count and interface requirements.
What is the operating temperature range of LM87CIMT/NOPB?
The LM87CIMT/NOPB is rated for commercial-grade operation from 0C to +70C ambient temperature, suitable for desktop and server environments with controlled thermal conditions.
