L9856-TR

L9856-TR Description

The L9856-TR from STMicroelectronics is a high-performance high-side gate driver IC designed for demanding power electronics applications. Packaged in an 8-pin SO (Small Outline) surface-mount configuration and supplied in Tape & Reel (TR), it is optimized for efficient automated assembly. Operating within a 4.4V to 6.5V supply range, this single-channel driver supports inverting input logic and delivers robust peak output currents of 500mA (source/sink). Its 150V maximum bootstrap voltage ensures compatibility with high-voltage systems, while its 100ns typical rise/fall times enable fast switching for reduced power losses.
