1 Channel High Side Switch IC

Current Limit High Side Switch IC

BD82048QVZ BD82049QVZ BD8205xQVZ Series

Description

BD820xxQVZ are Single Channel High Side Switch ICs

employing N-channel power MOSFET with low On

Resistance for the power supply line of universal serial

bus (USB).

These ICs have a built-in over current detection circuit,

thermal shutdown circuit, under voltage lockout and

soft start circuit.
