Because high-speed switching is possible, the IC can be efficiently set thereby saving energy. A gate protect diode is built-in to prevent static damage. The small SOT-89 package makes high density mounting possible. ## ■APPLICATIONS ## ●Notebook PCs ●Cellular and portable phones ●On-board power supplies ●Li-ion battery systems ## ■FEATURES **Low On-State Resistance** : Rds (on)= 0.05Ω@ Vgs = 4.5V : Rds (on)= 0.07Ω@ Vgs = 2.5V : Rds (on)= 0.15Ω@ Vgs = 1.5V **Ultra High-Speed Switching Gate Protect Diode Built-in** **Driving Voltage** : 1.5V **N-Channel Power MOSFET DMOS Structure Small Package** : SOT-89 **Environmentally Friendly** : EU RoHS Compliant, Pb Free **==> picture [179 x 95] intentionally omitted <==** **----- Start of picture text -----**
