MIC5891YWM-TR

Overview

The MIC5891YWM-TR is a high-voltage, high-current integrated circuit featuring eight CMOS data latches and bipolar Darlington transistor drivers. It operates with a supply voltage of 4.5V to 15V and supports load voltages from 5V to 50V. The device provides a maximum output current of 500mA per channel in an 8-output configuration. It utilizes serial and parallel interfaces for non-inverting input control. The component is housed in a 16-SOIC package and functions as a latch driver with high-side output configuration.

Feature Summary

• Integrates eight CMOS data latches with common strobe and output enable control circuitry
• Employs bipolar Darlington transistor drivers for high-current switching capability
• Supports serial and parallel interface modes for flexible logic control

Applications

• High-side power distribution in industrial systems
• Driving loads requiring high voltage and current in automotive applications
• General-purpose peripheral driver circuits in embedded systems

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing. Confirm that the operating temperature range meets the -55°C to 125°C requirement for the intended environment. Ensure the 16-SOIC footprint matches the PCB layout constraints. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when eight independent high-side switches are required with latched state retention. Consider the 500mA per-channel limit and 50V maximum load voltage against system demands. Evaluate the serial or parallel interface compatibility with the host microcontroller. Verify that the bipolar driver architecture suits the inductive or resistive load characteristics.

Part Context

This part belongs to the MIC5891 family of latched drivers manufactured by Microchip Technology. It succeeds earlier versions produced under the Micrel brand following acquisition. The device serves as a bridge between low-voltage logic controllers and high-power loads, offering robust protection and control features within a single integrated solution.
