open-drain comparator and internal reference

• QUIESCENT CURRENT: 1800mA (max)

providing a 0.6V threshold. External dividers are used

• PACKAGES: SO-8, MSOP-8

to set the current trip point. The comparator includes

a latching capability, which can be made transparent

APPLICATIONS

by grounding (or leaving open) the RESET pin.

• NOTEBOOK COMPUTERS

The INA200, INA201, and INA202 operate from a

• CELL PHONES

single +2.7V to +18V supply, drawing a maximum of

• TELECOM EQUIPMENT

1800mA of supply current. Package options include

the very small MSOP-8 and the SO-8. All versions

• AUTOMOTIVE

The input pins, VIN+ and VIN–, should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance. Power-supply bypass capacitors are required for stability.
PAGE 11
INA200 INA201 INA202 www.ti.com SBOS374C – NOVEMBER 2006 – REVISED OCTOBER 2010 Normal Case 1: VSENSE ≥ 20mV, VCM ≥ VS This region of operation provides the highest accuracy. Here, the input offset voltage is characterized and measured using a two-step method. First, the gain is determined by Equation 1. VOUT1 - VOUT2 G= 100mV - 20mV (1) larger-than-normal offset can appear at the current shunt monitor output with a typical maximum value of VOUT = 300mV for VSENSE = 0mV.
