The SGM8197 series is used for high-side current-sense 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 SGM8197 series: 10V/V, 20V/V, 50V/V and 100V/V, and the bandwidth reaches 1200kHz for SGM8197A1 (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, dependent on whether the RESET pin is pulled high or is left floating (or grounded).
The operating supply voltage of SGM8197 series is from 2.7V to 28V, with a typical supply current of 650μA.
The SGM8197 series is available in Green SOIC-8 and MSOP-8 packages. It is specified within -40℃ to +125℃ temperature range.
