3 Description
The CSD85301Q2 is a 20V, 23mΩ N-Channel
device with dual independent MOSFETs in a SON
2mm x 2mm plastic package. The two FETs were
designed to be used in a half bridge configuration
for synchronous buck and other power supply
applications. Additionally, this part can be used for
adaptor, USB input protection and battery charging
applications. The dual FETs feature low drain to
source on-resistance that minimizes losses and
offers low component count for space constrained
applications.
