Microchip | MIC2026-1YM-TR

Micrel Inc., is a leading manufacturer of IC solutions for the worldwide analog, Ethernet and high bandwidth markets. The Company's products include high performance analog, power, advanced mixed-signal and radio frequency semiconductors; high speed communication, clock management, Ethernet switch and physical layer transceiver integrated circuits.

The MIC2026 and MIC2076 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2026/76 are internally current limited and have thermal shutdown that protects the device and load. The MIC2076 offers “smart” thermal shutdown that reduces current consumption in fault modes. When a thermal shutdown fault occurs, the output is latched off until the faulty load is removed. Removing the load or toggling the enable input will reset the device output.
