3 Description
The INA200, INA201, and INA202 devices are high-
side current-shunt monitors with voltage output and
integrated comparator. The INA200–INA202 devices
can sense drops across shunts at common-mode
voltages from –16 V to 80 V. The INA200–INA202
devices are available with three output voltage
scales: 20 V/V, 50 V/V, and 100 V/V, with a
bandwidth up to 500-kHz.
The INA200, INA201, and INA202 devices also
incorporate an open-drain comparator and internal
reference providing a 0.6-V 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 devices operate
from a single 2.7-V to 18-V supply, drawing a
maximum of 1800 μA of supply current. Package
options include the very small VSSOP-8 and the
SOIC-8. All versions are specified over the extended
operating temperature range of –40°C to 125°C.
