HIGH-SIDE CURRENT MONITOR
■ DESCRIPTION
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
