The SGM8197xQ series is used for high-side currentsense automotive applications with an integrated amplifier output and an open-drain comparator with a 0.6V reference. The device can sense the voltage across a current-sense resistor at common mode voltages from -24V to 105V. There are four different gains for SGM8197xQ series: 10V/V, 20V/V, 50V/V and 100V/V, and the bandwidth reaches 1200kHz for SGM8197A1Q (20V/V).

An open-drain comparator and 0.6V voltage reference are integrated. The 0.6V reference is connected to the inverting input of comparator, and the current trip point can be set with the external voltage at the CMPIN pin. The comparator output can be transparent or latched, depending on whether the RESET pin is pulled high or left floating (or grounded).

The operating supply voltage of SGM8197xQ series is from 2.7V to 28V, with a typical supply current of 550μA.

The SGM8197xQ series is available in Green SOIC-8 and MSOP-8 packages. It is specified within -40℃ to +125℃ temperature range. This device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
