LC898300XA-MH

LC898300XA-MH Description

The LC898300XA-MH from onsemi is a high-performance CMOS-based motor driver IC designed for haptic feedback applications, specifically optimized for Linear Resonant Actuators (LRAs). Operating within a 2.7V to 3.3V supply range, it delivers a robust 150mA output current through its half-bridge (2) configuration, ensuring precise control of vibration intensity and frequency. Packaged in a compact 9WLP (Wafer Level Package) and available in Tape & Reel (TR), this surface-mount device is ideal for space-constrained designs. Although marked as Obsolete, it remains compliant with ROHS3 and REACH environmental standards, making it suitable for legacy or specialized applications requiring reliable haptic feedback solutions.
