MIC5891BWM TR

Overview

The MIC5891BWM-TR is a power distribution switch and load driver manufactured by Microchip Technology. It features an 8-channel output configuration with a 1:8 input-to-output ratio, housed in a 16-SOIC package. The device supports bipolar outputs and operates as a latch driver with non-inverting input logic. It handles load voltages from 5V to 50V and requires a supply voltage (Vcc/Vdd) between 4.5V and 15V. The maximum output current per channel is 500mA. The component utilizes parallel and serial interfaces for control. It is designed for surface mount installation and functions within a temperature range of -55°C to 125°C.
