Source terminal of the first P-channel MOSFET. Continuous ID = +/-9.0 A; body diode forward voltage VSD = -1.2 V max at IS = -9 A. |+| 2 | G1 | input | Tr1 Gate. Gate control input of the first P-channel MOSFET. VGS(th) = -1.0 V to -2.5 V; absolute max VGSS = +/-20 V. ESD protection diode to source is integrated. |+| 3 | S2 | passive | Tr2 Source. Source terminal of the second P-channel MOSFET. Continuous ID = +/-9.0 A; body diode forward voltage VSD = -1.2 V max at IS = -9 A. |+| 4 | G2 | input | Tr2 Gate. Gate control input of the second P-channel MOSFET. VGS(th) = -1.0 V to -2.5 V; absolute max VGSS = +/-20 V. ESD protection diode to source is integrated. |+| 5 | D2 | passive | Tr2 Drain. Drain terminal of the second P-channel MOSFET. Internally connected to pin 6 to spread current and dissipate heat. VDSS = -30 V, RDS(on) = 18.5 mOhm max. |+| 6 | D2 | passive | Tr2 Drain. Second drain lead of Tr2, internally shorted to pin 5. Provides parallel current path and heat-sinking. |+| 7 | D1 | passive | Tr1 Drain. Drain terminal of the first P-channel MOSFET. Internally connected to pin 8. VDSS = -30 V, RDS(on) = 18.5 mOhm max. |+| 8 | D1 | passive | Tr1 Drain. Second drain lead of Tr1, internally shorted to pin 7.
