MIC94052/94053
84m⦠P-Channel MOSFET in SC-70-6
Final
General Description
The MIC94052/94053 are low on-resistance, 84mâ¦(max) P-
channel 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
70m⦠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 pull-
up 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 â40°C
to +150°C.
