- Supports bipolar operation for brushed DC motors
- Dual half-bridge output configuration
Applications
- Fan motor drive systems
Procurement Notes
Verify the specific ordering suffix TLM3-H against official onsemi documentation to confirm package type and tape/reel specifications. Confirm end-of-life status prior to finalizing designs, as availability may be restricted. Ensure compliance with RoHS and halogen-free material requirements specified in the manufacturer's compliance statements before procurement.
Selection Notes
Select this component for applications requiring a compact, single-phase driver for small brushed DC fans. The wide operating voltage range accommodates various battery and regulated power sources. Consider the thermal performance of the HSSOP package if high ambient temperatures are expected within the specified operational limits.
Part Context
This part belongs to the LB11961 series of motor controllers from onsemi. It is categorized under standard products within the motor control segment. The device represents a specialized solution for low-power fan applications, distinct from general-purpose logic or power management ICs offered by the manufacturer.
Replacement Considerations
The LB11961-TLM-E is a related variant within the same series. Verify pinout compatibility and electrical parameter alignment when considering substitutes. Check current production status and lead times for alternative drivers if this specific suffix is unavailable.
