- Utilizes BICMOS process technology for reliable operation
- Supports direct connection to PC and server cooling systems
Applications
- Server chassis cooling fans
- Personal computer case fans
- Three-phase DC brushless motor control
Procurement Notes
Verify the specific suffix TLM-H against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target system's voltage requirements, which must remain between 6V and 15V. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm pinout alignment with the 20-SSOP footprint during PCB layout validation.
Selection Notes
Select this component when designing cooling solutions for low-voltage DC brushless fans in computing hardware. It is suitable for applications requiring integrated commutation without external microcontrollers. Consider the thermal performance of the SSOP package relative to the expected ambient temperature. Verify that the 1.2A current rating meets the peak demands of the selected fan motor model.
Part Context
This part belongs to the LV8804 family of motor drivers from onsemi, specialized for PC and server fan applications. The series focuses on simplifying design by integrating necessary drive logic into a single compact package. These components are widely used in consumer electronics and data center infrastructure where space efficiency and cost-effectiveness are critical for mass production.
Replacement Considerations
The LV8804V-MPB-H is a documented variant within the same product family. Verify pin compatibility and package differences before substitution. No other public substitute part numbers are confirmed for this specific model.
