Freescale AO8 8 22 / MC8 8 22 Dual N-Channel Logical Level MOSFET These miniature surface mount MOSFETs utilize a high cell density trench process to provide low rDS(on) and to ensure minimal power loss and heat dissipation. Typical applications are DC-DC converters and power management in portable and battery-powered products such as computers, printers, PCMCIA cards, cellular and cordless telephones. • • • • Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe TSSOP-8 saves board space Fast switching speed High performance trench technology PRODUCT SUMMARY VDS (V) rDS(on) (OHM) 0.022 @ VGS = 4.5 V 20 0.030 @ VGS = 2.5V 5.8 0.047 @ VGS = 1.8V 4.7 TSSOP-8 Top View D1 S1 1 2 S1 G1 3 4 ID (A) 6.8 D2 D1 8 D2 7 6 S2 S2 G2 5 G2 G1 S1 N-Channel MOSFET S2 N-Channel MOSFET o ABSOLUTE MAXIMUM RATINGS (T A = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Maximum Units Drain-Source Voltage VDS 20 V Gate-Source Voltage VGS ±12 o TA=25 C a Continuous Drain Current o TA=70 C b Pulsed Drain Current a Continuous Source Current (Diode Conduction) 6.8 ID IDM ±30 IS 1.5 o TA=25 C a Power Dissipation o TA=70 C THERMAL RESISTANCE RATINGS Parameter a Maximum Junction-to-Ambient t <= 10 sec Steady State A 1.5 PD W 1.0 TJ, Tstg Operating Junction and Storage Temperature Range A 5.4 o -55 to 150 Symbol Typ Max RthJA 72 100 83 120 C o C/W Notes a.
