DESCRIPTION
The INA200-Q1, INA201-Q1, and INA202-Q1 are
high-side current-shunt monitors with voltage output.
The INA200-Q1–INA202-Q1 can sense drops across
shunts at common-mode voltages from –16V to 80V.
The INA200-Q1–INA202-Q1 are available with three
output voltage scales: 20V/V, 50V/V, and 100V/V,
with up to 500kHz bandwidth.
The INA200-Q1, INA201-Q1, and INA202-Q1 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-Q1, INA201-Q1, and INA202-Q1 operate
from a single +2.7V to +18V supply, drawing a
maximum of 1800μA of supply current. Package
option include the very small MSOP-8. All versions
are specified over the extended operating
temperature range of –40°C to 125°C.
