PRELIMINARY ■ DESCRIPTION
AA1850
HIGH-SIDE CURRENT MONITOR
The AA1850 is a high side current sense monitor. It takes a high side voltage developed across a current shunt resistor and translates it into a proportional output current. A customer defined output resistor converts the output current into a reference voltage. It operates over a wide input voltage range, from 2.5V to 20V and makes it suitable for many applications. A minimum operating current of 4uA, combined with its SOT23 package make it a right solution for portable equipment. ■ FEATURES Low cost and accurate high-side current monitor. Up to 2.5V sense voltage. 2.5V – 20V supply range. 4uA quiescent current. 1% typical accuracy.
■ APPLICATIONS Battery chargers DC motor control Over current monitor Power management Programmable current source ■ BLOCK DIAGRAM
