MIC5891YWM-TR

Product Overview

The Microchip Technology MIC5891YWM-TR is a surface-mount 16-SOIC high-side power switch driver with a 1:8 input-to-output ratio and eight bipolar outputs. It uses a strobe and serial interface, accepts non-inverting inputs, and supports load voltages from 5V to 50V while operating from a 4.5V to 15V supply. It provides a maximum output current of 500mA, and the device is specified for an ambient temperature range of -55°C to 125°C.

Key Features

• Latched driver topology with eight high-side bipolar outputs in a 1:8 input-to-output configuration.
• Strobe and serial interface with non-inverting inputs for output switching.
• 500mA maximum output current, 5V to 50V load range, and 4.5V to 15V supply range.
• Surface-mount 16-SOIC package specified for -55°C to 125°C ambient operation.

Applications

• Switching or driving multiple load channels in equipment that requires high-side bipolar outputs.
• Controlling outputs through a strobe and serial interface in board-level power distribution.
• Use in systems needing a 5V to 50V load range with output current up to 500mA.

Design & Procurement Notes

Designers should verify that the load voltage remains within 5V to 50V and that the supply voltage stays between 4.5V and 15V before selecting this driver. The 500mA output current limit and high-side bipolar configuration affect load placement, current budgeting, and switching behavior. The strobe and serial interface should be matched to the controller's output format and non-inverting input expectations. The 16-SOIC surface-mount package and -55°C to 125°C ambient range support compact board layouts with wide temperature operation.
