FDC6329L
Integrated Load Switch
General Description Features
This device is particularly suited for compact power VDROP=0.2V @ VIN=5V, IL=2.8A. R(ON) = 0.07 VDROP=0.2V
management in portable electronic equipment where @ VIN=2.5V, IL=1.9A. R(ON) = 0.105.
2.5V to 8V input and 2.5A output current capability are
needed. This load switch integrates a small N-Channel Control MOSFET (Q1) includes Zener protection for ESD
power MOSFET (Q1) which drives a large P-Channel ruggedness (>6KV Human Body Model).
power MOSFET (Q2) in one tiny SuperSOTTM-6
package. High performance trench technology for extremely low
on-resistance.
SuperSOTTM-6 package design using copper lead frame for
superior thermal and electrical capabilities.
