Bi-Directional P-Channel MOSFET/Power Switch PRODUCT SUMMARY V DS (V) R DS(on) (Ω) I D (A) ± 7 DESCRIPTION.7 at V GS = -.5 V ±.. at V GS = -.5 V ±. The is a low on-resistance p-channel power MOSFET providing bi-directional blocking and conduction. Bi-directional blocking is facilitated by combining a -terminal symmetric p-channel MOSFET with a body bias selector circuit a. Circuit operation automatically biases the p-channel body to the most positive source/drain potential thereby maintaining a reverse bias across the diode present between the source/drain terminals. Off-state device blocking characteristics are symmetric, facilitating bi-directional blocking for high-side battery switching in portable products. Gate drive is facilitated by negatively biasing the gate relative to the body potential. The off-state is achieved by biasing the gate to the most positive supply voltage or to the body potential. The is available in a -pin TSOP- package rated for the - 5 C to 85 C commercial temperature range.
