Overview
The LV88564RTXG is a non-automotive brushless DC (BLDC) motor driver manufactured by onsemi. It operates with a single-phase PWM full-wave configuration, designed for 24V/48V fan applications. The device supports a supply voltage range of 3.9V to 16V and delivers an output current of up to 50mA. Housed in a compact 20-VFQFN package (20-VCT, 3x3mm), it integrates controller functions for commutation and direction management. The component is rated for an operating temperature range of -40°C to 105°C.
Feature Summary
- Integrates half-bridge pre-driver output configuration for single-phase BLDC control
- Supports PWM interface for precise commutation and direction management
- Designed specifically for non-automotive fan motor applications
Applications
- 24V/48V fan motor control systems
- Non-automotive brushless DC motor drives
- Single-phase BLDC commutation circuits
Procurement Notes
Verify the obsolete status and end-of-life notification dated April 7, 2021, before procurement. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics, as standard production has ceased. Ensure the specific suffix matches the required tape-and-reel packaging format for integration into existing designs.
Selection Notes
Select this component for low-current single-phase BLDC applications requiring integrated commutation logic. The 50mA output capability suits small fan motors rather than high-power loads. Consider the 20-VFQFN package size for space-constrained PCB layouts. Verify that the 3.9V–16V supply range aligns with the system's power architecture and that the non-automotive rating meets the application's environmental requirements.
Part Context
This part belongs to the LV8856x series of single-phase BLDC motor drivers from onsemi. It shares functional similarities with models like the LV88561JA-AH but differs in packaging and specific suffix designations. The series targets cost-effective, compact motor control solutions for consumer and industrial non-automotive electronics, emphasizing ease of use through integrated driver stages.
Replacement Considerations
Public confirmed substitute part numbers are not available due to the product's obsolete status. Designers should evaluate alternative single-phase BLDC drivers from onsemi or other manufacturers that offer current production status and compatible pinouts.
