MIC940514-Terminal P-Channel MOSFET High-Side Switch | FETs, MOSFETs | 1 | Active | 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. |

| Power Management (PMIC) | 3 | Active | The MIC94060-63 are high-side load switches designed for operation between 1.7V to 5.5V. The devices contain a low on-resistance P-channel MOSFET that supports over 2A of continuous current. The MIC94061and MIC94063 features an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state.
MIC94060-61 feature rapid turn on while MIC94062-63 provide a slew rate controlled Soft-Start turn-on of 800µs (typical) to prevent in-rush current from glitching supply rails.
An active pull-down on the enable input keeps MIC94060-63 in a default OFF state until the EN pin is pulled to a high level. Built-in level shift circuitry allows low voltage logic signals to switch higher supply voltages, or vice versa; high level logic signals can control low level voltages.
MIC94060-63's operating voltage range makes them suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as all 5V applications. Their low operating current of 2µA and low shutdown current of <1µA maximize battery life. |
