Integrated Load Switch
General Description This device is particularly suited for compact power management in portable electronic equipment where 2.5V to 8V input and 2.8A output current capability are needed. This load switch integrates a small N-Channel power MOSFET (Q1) that drives a large P -Channel power MOSFET (Q2) in one tiny SuperSOTT M-6 package. Applications Load switch Power management
Features
–2.8 A, –8 V. RDS(ON) = 55 mΩ @ V GS = –4.5 V RDS(ON) = 70 mΩ @ V GS = –2.5 V RDS(ON) = 100 mΩ @ V GS = –1.8 V Control MOSFET (Q1) includes Zener protection for ESD ruggedness (>6KV Human body model) High performance trench technology for extremely low RDS(ON)
