SGM8197

High-Side Current-Sense Amplifier

with Open-Drain Comparator and Reference

GENERAL DESCRIPTION

FEATURES

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.

● Power Supply Range: 2.7V to 28V

● Quiescent Current: 650μA (TYP)

● Choice of Gains:

The device can sense the voltage across

 SGM8197A0 Gain: 10V/V

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).

 SGM8197A1 Gain: 20V/V

 SGM8197A2 Gain: 50V/V

 SGM8197A3 Gain: 100V/V

● High Accuracy: 1.2% (MAX) Gain Error

● Input Common Mode Voltage Range: -24V to 105V

● Bandwidth: 1200kHz (SGM8197A1)

● Voltage Reference of the Comparator: 0.6V (TYP)

● Comparator with an Open-Drain Output

● Capability of Latching on the Comparator Output

● -40℃ to +125℃ Operating Temperature Range

● Available in Green SOIC-8 and MSOP-8 Packages

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 CMP_INpin.

The comparator output can be transparent or latched,

��

depending on whether the RESET pin is pulled high or

left floating (or grounded).

APPLICATIONS

The operating supply voltage of SGM8197 series is

from 2.7V to 28V, with a typical supply current of

650μA.
