Product Introduction

Overview

The L9959T-TR-D, produced by STMicroelectronics, is a single and dual integrated PMOS high-side H-bridge designed for driving resistive and inductive loads. This component features output current direction and supervising functions, making it versatile for various automotive and industrial applications. The L9959T-TR-D is housed in a PowerSSO36 package, which includes two H-Bridges that can operate in parallel through independent input driving commands, as well as a single full H-Bridge. This design enhances PCB footprint efficiency across different target applications.
