Overview
The LV8804FV-TRM-H is a sensorless brushless DC (BLDC) motor driver designed for three-phase fan applications. It operates within a supply voltage range of 6V to 15V and delivers an output current of 1.2A per phase. The device utilizes a half-bridge output configuration with three channels. It supports On/Off interface control and functions reliably across an operating temperature range of -30°C to 95°C. The component is housed in a 20-pin SSOP package.
Feature Summary
- Sensorless control architecture for three-phase BLDC motors
- Integrated half-bridge output stage for direct fan drive
- Wide operating voltage compatibility for standard low-voltage systems
Applications
- Computer cooling fans
- Server chassis ventilation
- Consumer electronics thermal management
Procurement Notes
Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the requested part matches the exact electrical ratings required for the target application, particularly regarding the 1.2A output current limit and 6V-15V supply range constraints.
Selection Notes
Select this component when designing systems requiring simple on/off control for small three-phase fans without complex PWM requirements. It is suitable for cost-sensitive applications where sensorless operation reduces system complexity. Confirm that the thermal environment stays within the specified -30°C to 95°C ambient temperature limits during operation.
Part Context
This part belongs to the LV8804 family of motor drivers from onsemi. These devices are engineered specifically for fan motor applications, offering a compact solution for managing brushless DC motors in space-constrained electronic assemblies. The family focuses on reliability and ease of integration for basic cooling tasks.
Replacement Considerations
Check for pin-compatible alternatives such as the LV8804TLM-H if different packaging or reel specifications are required. Verify that any substitute maintains the same 6V-15V input range and 1.2A current capability.
