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 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
? 2.5 V to 5.5 V Operation
? Exceeds ± 2 kV ESD Protected
? Solution for High-Side Battery Disconnect Switching
(BDS)
? Supports Battery Switching in Multiple Battery Cell
Phones, PDAs and PCS Products
? Low Profile, Small Footprint TSOP-6 Package
? Compliant to RoHS Directive 2002/95/EC
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 Si3831DV is available in a 6-pin TSOP-6
package rated for the - 25 °C to 85 °C commercial
temperature range.
