DESCRIPTION
The Si3831DV is a low on-resistance p-channel power
MOSFET providing bi-directional blocking and conduction.
Bi-directional blocking is facilitated by combining a 4-terminal
symmetric p-channel MOSFET with a body bias selector
circuit*. 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.
*Patents pending.

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 Si3831DV is available in a 6-pin TSOP-6
package rated for the –25 to 85°C commercial temperature
range.
