MIC94050中文资料4-Terminal P-Channel MOSFET High-Side Switch数据手册Microchip规格书

描述 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 0.125 Ohm 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 pull-up 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. This 4-terminal configuration improves the θJA (improved heat dissipation) and makes reverse-blocking switch applications practical.The small size, low threshold, and low RDS(on) make the MIC94050/1 the ideal choice for PCMCIA, USB, back-up battery-power, and distributed power management applications.
