AM4841P AO4485/ MC4485 Analog Power Freescale P-Channel 40-V (D-S) 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. • • • • PRODUCT SUMMARY VDS (V) rDS (on ) m(Ω) 35 @ VGS = -10V -40 45 @ VGS = -4.5V Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe SOIC-8 saves board space Fast switching speed High performance trench technology ID (A) -9.0 -7.2 1 8 2 7 3 6 4 5 o ABSOLUTE MAXIMUM RATINGS (T A = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Maximum Units VDS Drain-Source Voltage -40 V VGS Gate-Source Voltage ±20 TA=25 oC a Continuous Drain Current Pulsed Drain Current o TA=70 C b a Continuous Source Current (Diode Conduction) -9.0 I D -7.3 IDM ±50 IS -2.1 o TA=25 C a Power Dissipation o TA=70 C THERMAL RESISTANCE RATINGS Parameter Maximum Junction-to-Ambient a Steady State R θJA o C -55 to 150 Maximum 50 92 Notes a.
