NCS21671DM025R2G

NCS21671DM025R2G is a NCS21671 series of voltage output current sense amplifier. The low offset of the zero−drift architecture enables current sensing with voltage drops across sense resistors as low as 10mV full-scale. An optional enable function is available to reduce current drain through the input pins and power supply pins to negligible levels when disabled or if Vs is less than 1.5V. Two optional pins are included to simplify input filtering. This device can operate from a single +1.8V to +5.5V power supply, drawing a maximum of 80A of supply current. Typical applications are power bus monitoring, battery current monitor, and lighting ballast.
