MAX49925 Description

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 high-voltage spikes. The wider input protection range also helps relax TVS requirements, leading to lower BOM cost and reduced component size.

The MAX49925 is well-suited for phase-current monitoring of inductive loads, such as motors and solenoids, where pulse-width modulation (PWM) is used to control the drive voltage and current.

The MAX49925 uses an improved technique to help reject common-mode input PWM edges with slew rates up to and beyond 500V/μs.

The MAX49925 operates over the full -40°C to +125°C temperature range and runs from a supply voltage of +2.7V to +5.5V. It is available in a 3mm x 3mm, 10-pin TDFN package with side-wettable flanks.
