MAX9918/19/20: High-side current-sense amplifiers provide wide common-mode range for automotive applications

Maxim Integrated Products introduces the MAX9918/MAX9919/MAX9920, the newest members of its industry-leading portfolio of high-side current-sense amplifiers (CSAs). Designed for automotive applications, these CSAs have a wide input common-mode range (-20V to +75V) to protect against beyond-the-rails voltages. These robust devices are well suited for monitoring inductive loads, such as motors and solenoids, where common-mode voltages can become negative due to inductive kickback, reverse-battery conditions, or transient events.
