What the LM96000CIMTX is and where it fits
The Texas Instruments LM96000CIMTX is a hardware monitor IC that integrates an internal temperature sensor and supports one external diode-connected transistor for remote temperature sensing. Its internal topology combines a sigma-delta ADC, comparator, fan control logic, multiplexer, and register bank on a single die, making it a centralized thermal-management controller for a PCB or system. Typical applications include desktop and notebook computers, servers, telecom equipment, and industrial controllers where multiple temperature points plus fan-speed regulation are needed over a 0°C to 125°C sensing range. The device communicates over a 2-wire SMBus interface, and its fan-control output allows closed-loop speed adjustment based on temperature readings.
Accuracy and temperature range — what they mean for the BOM
The LM96000CIMTX specifies ±3°C maximum error on its local sensor and ±4°C maximum on the remote channel. This is adequate for thermal-throttling triggers and fan-speed ramping.
Supply voltage and interface
The device runs from a 3V to 3.6V supply, which maps cleanly onto a standard 3.3V rail. No extra regulator needed if your board already carries 3.3V. The SMBus output is 2-wire and shares the same supply domain; pull-up resistors to 3.3V are required on the bus lines. The LM96000CIMTX does not provide an alarm output pin — all status is read over the SMBus interface, so the host controller must poll or use SMBus Alert if supported.
Package and shipping form — a sourcing note
The LM96000CIMTX is supplied in a 24-lead TSSOP package with a 4.40 mm body width, surface-mount. If your pick-and-place line expects tape-and-reel, confirm the reel option before committing to this order code.
Lifecycle and compliance — the sourcing decision
However, the part is RoHS non-compliant (lead-bearing), which restricts its use in EU-market products under the RoHS directive and in any RoHS-mandated BOM. If your assembly requires RoHS compliance, look at the lead-free variants.
