MAX49925 Bidirectional Current-Sense Amplifiers

Analog Devices Inc. MAX49925 Bidirectional Current-Sense Amplifiers (CSA) offer an input common-mode range that extends from -40V to +76V, making them suitable for 48V hybrid electric vehicle (HEV) applications with large automotive transients. This CSA series features an extended input protection range of -42V to +80V against reverse-battery and high-voltage spikes. The wider input protection range also helps relax TVS requirements, lowering BOM cost and component size. The amplifiers are well-suited for phase-current monitoring of inductive loads, such as motors and solenoids, where pulse-width modulation (PWM) controls the drive voltage and current.
