EM5209

Dual Channel, Ultra-Low Resistance Load Switch

General Description

Applications

The EM5209 is a small, ultra-low RON, dual

channel load switch with controlled turn on. The

device contains two N-channel MOSFETs that can

operate over an input voltage range of 0.8V to 5.5V

and can support a maximum continuous current of

6A per channel. Each switch is independently

controlled by an on/off input (ON1 and ON2),

which is capable of interfacing directly with

low-voltage control signals. In EM5209, a 220-Ω

on-chip load resistor is added for quick output

discharge when switch is turned off.
