MIC5801YWM-TR – MICREL

The MIC5801YWM-TR is a monolithic, high-voltage, high-current bipolar power driver integrated circuit fabricated by Micrel (now Microchip Technology). It is configured as a single-channel (1:1) driver, housed in a 24-pin Small Outline Integrated Circuit (SOIC) package with tape and reel packaging (TR). The device is designed to interface low-level logic signals with high-power loads, typically inductive loads such as relays, solenoids, and stepper motors. Key specifications include a maximum output voltage rating, typically in the range of 80V, and a continuous output current capability of up to 500mA per channel. Internal suppression diodes provide protection against inductive kickback. Input logic compatibility includes TTL and 5V CMOS. The SOIC package offers improved thermal performance compared to DIP packages, facilitating heat dissipation. Applications include industrial controls, automotive systems, and general-purpose power switching.
