anasem inc. 1 rev. e09-08 products data sheet anasem analog semiconductor ic .......... futu re of the analog world 20~50ma current detection, cmos+mr monolithic current sensor switch csl2050dta general descriptions csl series are ac or dc current sensor switch with cmos+mr monolithic structure. the current fr om 10 to 200ma can be measured in high accuracy by the resistance of 10m ? . it is molded in a micro sot- 26 package because of a monolithic structure. because the bridge structure of mr is adopted for the current detection, high sensitivity and high accuracy te mperature characteristic have been achieved. the measurement and the di rection of the current value can be measured at the same time. the detection current value of the sw itch is fixed by laser trim. the measurement up to 800ma is possible in csm and csh series. features z detection current (csl series) z operating voltage range z maximum detection current z low detection line resistance z low current consumption z stand-by current z operating temperature range z small package z reverse-voltage connection protection z ac or dc current detection z output over drive protection applications z over current detection z battery current detection z switching power supply z motor control feedback detection halogen rohs compliance 10ma ~ 200ma 1.6v ~ 6.0v 500ma 0.8 ? typ. 4.7 a (v in =3.3v, ta=25c) max. 0.1 a -40 ~ +85c sot-26 (400mw) z lamp disconnection detection z power failure detection z reverse-voltage connection protection z usb over current detection
