MIC94050 - P-Channel MOSFET

General Description

The MIC94050 and MIC94051 are 4-terminal silicon gate P-channel MOSFETs that provide low on-resistance in a very small package.

Designed for high-side switch applications where space is critical, the MIC94050/1 exhibits an on-resistance of typically 0.125Ω at 4.5V gate-to-source voltage.

Key Features

  • 0.125Ω typical on-resistance at 4.5V gate-to-source voltage.
  • Operates with 1.8V gate-to-source voltage.
  • Separate substrate connection allows reverse-blocking.

MIC94050/94051 Micrel MIC94050/94051 4-Terminal SymFET™ P-Channel MOSFET General Description The MIC94050 and MIC94051 are 4-terminal silicon gate P-channel MOSFETs that provide low on-resistance in a very small package. Designed for high-side switch applications where space is critical, the MIC94050/1 exhibits an on-resistance of typically 0.125Ω at 4.5V gate-to-source voltage. The MIC94050/1 also operates with only 1.8V gate-to-source voltage. The MIC94050 is the basic 4-lead P-channel MOSFET. The MIC94051 is a variation that includes an internal gate pullup resistor that can reduce the system parts count in many applications. The 4-terminal SOT-143 package permits a substrate connection separate from the source connection.
