DESCRIPTION
The INA200, INA201, and INA202 are high-side
current-shunt monitors with voltage output. The
INA200–INA202 can sense drops across shunts at
common-mode voltages from –16V to 80V. The
INA200–INA202 are available with three output
voltage scales: 20V/V, 50V/V, and 100V/V, with up to
500kHz bandwidth.
The INA200, INA201, and INA202 also incorporate an
open-drain comparator and internal reference
providing a 0.6V threshold. External dividers are used
to set the current trip point. The comparator includes
a latching capability, which can be made transparent
by grounding (or leaving open) the RESET pin.
The INA200, INA201, and INA202 operate from a
single +2.7V to +18V supply, drawing a maximum of
1800mA of supply current. Package options include
the very small MSOP-8 and the SO-8. All versions
are specified over the extended operating
temperature range of –40°C to +125°C.
