SGM8199

Voltage Output,

High-Side or Low-Side Measurement,

Bidirectional Current Shunt Monitor

GENERAL DESCRIPTION

FEATURES

The SGM8199 series is a voltage output, bidirectional

current shunt monitor, which is designed to sense

voltage drops across the shunt at common mode

voltage range without being affected by the supply

voltage. The device features a wide common mode

voltage range from -0.1V to 26V. It also offers a low

offset, which allows 10mV full-scale maximum drops

across the shunt when sensing current.

 Wide Input Common Mode Range: -0.1V to 26V

 Low Input Offset Voltage:

SGM8199A0: 600μV (V_CM= 12V, MAX)

SGM8199A1: 350μV (V_CM= 12V, MAX)

SGM8199A2: 250μV (V_CM= 12V, MAX)

(Enable 10mV Full-Scale Shunt Drops)

 Gain Options:

SGM8199A0 Gain: 20V/V

SGM8199A1 Gain: 50V/V

The SGM8199 series provides three fixed gains: 20V/V,

50V/V and 100V/V. It operates from 2.7V to 26V single

supply, consuming only 85µA quiescent current.

SGM8199A2 Gain: 100V/V

 Gain Error:

SGM8199A0: ±0.7% (MAX)

The SGM8199 series is available in a Green SC70-6

package. It is specified over the extended -40℃ to

+125℃ temperature range.

SGM8199A1: ±0.4% (MAX)

SGM8199A2: ±0.4% (MAX)

 Low Quiescent Current: 85μA (TYP)

 -40℃ to +125℃ Operating Temperature Range

 Available in a Green SC70-6 Package
