MAX49925 Current-Sense Amplifier

The MAX49925 is a bidirectional current-sense amplifier (CSA) with an input common-mode range that extends from -40V to +76V, making it suitable for 48V HEV applications where there are large automotive transients. This CSA has an extended input protection range of -42V to +80V against reverse-battery and highvoltage spikes. The wider input protection range .
