Overview
The LB11970FV-TLM-H is a monolithic digital integrated circuit designed as a single-phase full-wave driver for brushless DC (BLDC) fan motors. It operates within a voltage supply range of 4.5 V to 16 V and supports load voltages from 3.5 V to 16 V. The component is housed in an SSOP-18 package, providing a compact solution for motor control applications requiring reliable single-phase drive capabilities.
Feature Summary
- Monolithic digital IC architecture optimized for single-phase full-wave driving
- Designed specifically for brushless DC (BLDC) fan motor applications
- Operates with standard low-voltage power supply ranges
Applications
- Brushless DC fan motor control systems
- Single-phase full-wave motor driver circuits
- Electronic cooling devices utilizing BLDC fans
Procurement Notes
Verify the manufacturer origin, as Sanyo semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix TLM-H corresponds to the required packaging and tape-and-reel specifications. Ensure compatibility with the intended voltage supply range of 4.5 V to 16 V before integration into the design.
Selection Notes
Select this component for applications requiring a dedicated single-phase driver for BLDC fans. Verify that the system voltage falls within the specified 4.5 V to 16 V supply range. Consider the SSOP-18 package constraints for PCB layout and thermal management requirements relative to the expected motor current load.
Part Context
This part belongs to the LB11970 series of monolithic digital ICs. These components are engineered as full-wave drivers for single-phase motors. The series typically targets cost-effective and space-constrained motor control solutions in consumer electronics and appliance cooling systems.
Replacement Considerations
Check for direct equivalents in the LB11970 family or compatible single-phase BLDC drivers from ON Semiconductor, which succeeded Sanyo's semiconductor division. Verify pinout compatibility and electrical parameter alignment before substitution.
