MIC94030/94031 TinyFET® P-Channel MOSFET General Description Features The MIC94030 and MIC94031 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 MIC94030/1 exhibits an on-resistance of typically 0.75Ω at 4.5V gate-to-source voltage. The MIC94030/1 also operates with only 2.7V gate-to-source voltage. The MIC94030 is the basic 4-lead P-channel MOSFET. The MIC94031 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 4terminal configuration improves the θJA (improved heat dissipation) and makes analog switch applications practical. The small size, low threshold, and low RDS(on) make the MIC94030/1 the ideal choice for PCMCIA card sleep mode or distributed power management applications. • 13.5V minimum drain-to-source breakdown • 0.75Ω typical on-resistance – at 4.5V gate-to-source voltage • 0.45Ω typical on-resistance – at 10V gate-to-source voltage • Operates with 2.7V gate-to-source voltage • Separate substrate connection for added control • Industry’s smallest surface mount package Applications • • • • • Distributed power management PCMCIA card power management Battery-powered computers, peripherals Hand-held bar-code scanners Portable communications equipment Ordering Information Part Number Junction Temp.
