AnaSem Inc. Rev. E09-08 Products Data Sheet AnaSem Analog Semiconductor IC 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 from 10 to 200mA can be measured in high accuracy by the resistance of 10m Ω. 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 temperature 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.
