SI4420DY

Si4420DY* Single N-Channel Logic Level PowerTrench MOSFET General Description Features This N-Channel Logic Level MOSFET is produced using Fairchild Semiconductor's advanced PowerTrench process that has been especially tailored to minimize on-state resistance and yet maintain superior switching performance. • • Low gate charge. This device is well suited for low voltage and battery powered applications where low in-line power loss and fast switching are required. • Fast switching speed. • Applications High performance trench technology for extremely low RDS(ON). • High power and current handling capability. • • • 12.5 A, 30 V. RDS(ON) = 0.009 W @ VGS = 10 V RDS(ON) = 0.013 W @ VGS = 4.5 V Battery switch Load switch Motor controls ' ' ' ' 62 6 6 6 * $EVROXWH0D[LPXP5DWLQJV $ 7  6\PERO         ƒ&XQOHVVRWKHUZLVHQRWHG 3DUDPHWHU 5DWLQJV 8QLWV 9 9'66 'UDLQ6RXUFH9ROWDJH  9*66 *DWH6RXUFH9ROWDJH – 9 ,' 'UDLQ&XUUHQW  $ &RQWLQXRXV 1RWHD 3XOVHG 3' 3RZHU'LVVLSDWLRQIRU6LQJOH2SHUDWLRQ  1RWHD  1RWHE  1RWHF 7-767* 2SHUDWLQJDQG6WRUDJH-XQFWLRQ7HPSHUDWXUH5DQJH :  WR •& 7KHUPDO&KDUDFWHULVWLFV 5q -$ 7KHUPDO5HVLVWDQFH-XQFWLRQWR$PELHQW 1RWHD  •&: 5q -& 7KHUPDO5HVLVWDQFH-XQFWLRQWR&DVH 1RWH  •&: 3DFNDJH2XWOLQHVDQG2UGHULQJ,QIRUPDWLRQ 'HYLFH0DUNLQJ 'HYLFH 5HHO6L]H 7DSH:LGWK 4XDQWLW\  6,'< ¶¶ PP XQLWV  'LHDQGPDQXIDFWXULQJVRXUFHVXEMHFWWRFKDQJHZLWKRXWSULRUQRWLILFDWLRQ ã1999 Fairchild Semiconductor Corporation Si4420DY Rev.
