Applications
The MIC2981/82YWM-TR is well suited for driving relays, solenoids, and indicator lamps in industrial control panels and building automation systems where 8 simultaneous high-side loads must be switched from a single logic bus. It is also used in LED matrix driver stages and stepper motor pre-drive circuits where the 50 V tolerance and integrated transient clamps simplify board layout. Printers, PLC output modules, and automotive body-control modules benefit from its combination of high current per channel and small SOIC-18 footprint.

Frequently Asked Questions
How much continuous output current can each channel of the MIC2981/82YWM-TR source?
Each of the 8 channels can source up to 500 mA continuously, and the device tolerates output voltages up to 50 V, making it suitable for driving relays, solenoids, and high-brightness LEDs directly from a 5 V or 3.3 V logic bus without external discrete transistors.
Does the MIC2981/82YWM-TR include built-in protection against inductive load transients?
Yes, the device integrates clamp diodes on all 8 output channels to suppress inductive kick-back transients generated by relays and solenoids. This built-in protection eliminates the need for external flyback diodes, reducing BOM count and PCB area in industrial output-stage designs operating at up to 50 V.
Which industrial or building-automation applications benefit most from the MIC2981/82YWM-TR source driver array?
PLC digital output modules, HVAC actuator controllers, and building-automation relay boards are the primary targets because all 8 channels can be activated simultaneously, each at 500 mA, to drive multiple 24 V or 48 V coil loads. The SOIC-18 package fits standard automated assembly lines, lowering production cost.
What logic input levels are compatible with the MIC2981/82YWM-TR, and can it interface directly with a 3.3 V microcontroller?
The MIC2981/82YWM-TR accepts standard TTL and CMOS logic levels, so a 3.3 V microcontroller GPIO can drive the inputs directly without a level shifter. The input threshold is compatible with signals in the 0 V to 5 V range, and the device operates from a supply voltage up to 50 V on the output side.
