MIC94052/94053 Micrel MIC94052/94053 84mΩ Ω P-Channel MOSFET in SC-70-6 Final General Description Features The MIC94052/94053 are low on-resistance, 84mΩ(max) Pchannel MOSFETs. They are housed in a Teeny™ SC-70-6 package. Designed for high-side switch applications where space is critical, the MIC94052/3 exhibit a typical on-resistance of 70mΩ at 4.5V gate-to-source voltage. The devices operate down to 1.8V gate-to-source voltage. Their operating voltage range makes the MIC94052/3 ideal for Li Ion applications as well as other sub-5V load switch applications. The MIC94053 is an option that includes an internal gate pullup resistor. The pull-up resistor ensures that the P-channel MOSFET is OFF until actively pulled down. Integrating the pull-up resistor saves valuable board space and reduces component placement cost. The MIC94052/3 have a junction temperature range of –40°C to +150°C. • 1.8V to 5.5V input voltage range • Low on-resistance P-channel MOSFET: 70mΩ at VGS = 4.5V (typ) 2A continuous current • VGS pull-up resistor (MIC94053) • Teeny™ SC-70-6 package • –40°C to +150°C junction temperature range Applications • Load switch in portable applications: Cellular phones PDAs MP3 players Notebook PCs Barcode scanners Ordering Information Part Number Gate-Source Pull Up Marking Junction Temp.
