20~50mACurrent 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 10mΩ. 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 direction of the current value can

be measured at the same time.

The detection current value of the switch is fixed by laser trim. The

measurement up to 800mA is possible in CSM and CSH series.
