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.
