Frequently Asked Questions
How much output current can each channel of the MIC2981/82YN source?
Each of the 8 output channels on the MIC2981/82YN can source up to 50 mA, with a total combined package current not exceeding 500 mA. This makes it ideal for driving LEDs, relays, or solenoids directly from 5 V logic systems without external transistors.
Which input logic families are compatible with the MIC2981/82YN?
The MIC2981/82YN accepts standard TTL and CMOS input levels, compatible with 5 V logic families. Its input threshold typically falls below 2.4 V, allowing direct connection to microcontroller GPIO pins rated at 3.3 V or 5 V without additional level-shifting circuitry.
For industrial relay driving, does the MIC2981/82YN include protection against inductive kickback?
Yes. The MIC2981/82YN includes built-in transient protection on all 8 output channels, suppressing voltage spikes generated by inductive loads such as relay coils and solenoids. This eliminates the need for external flyback diodes in most applications operating below 50 V.
When would MIC2981/82YN be a better choice than using discrete NPN transistors for an 8-channel driver?
MIC2981/82YN integrates 8 drivers in a single DIP-18 package, reducing board space compared to 8 discrete transistors. Each output handles up to 50 mA, and the built-in transient clamping eliminates 8 external flyback diodes, cutting component count and BOM cost significantly.
