1 Channel Compact High Side Switch ICs

1ch Adjustable Current Limit

High Side Switch ICs

BD2222G BD2242G BD2243G

Description

Key Specifications

BD2222G, BD2242G and BD2243G are low

¢ IN Operating Voltage:

¢ On Resistance: (VIN=5V)

¢ Current Limit Threshold:

¢ Standby Current:

2.8V to 5.5V

89mΩ(Typ)

0.2A to 1.7A adjustable

0.01µA (Typ)

on-resistance N-channel MOSFET high-side power

switches, optimized for Universal Serial Bus (USB)

applications. These devices are equipped with the

function of over-current detection, thermal shutdown,

under-voltage lockout and soft-start. Moreover, the

range of Current limit threshold can be adjusted from

0.2A to 1.7A by changing the external resistance.

¢ Operating Temperature Range:

-40°C to +85°C
