FEATURES
DESCRIPTION
• COMPLETE CURRENT SENSE SOLUTION
• 0.6V INTERNAL VOLTAGE REFERENCE
The INA200, INA201, and INA202 are high-side
current-shunt monitors with voltage output. The
• INTERNAL OPEN-DRAIN COMPARATOR
INA200–INA202 can sense drops across shunts at
• LATCHING CAPABILITY ON COMPARATOR
common-mode voltages from –16V to 80V. The
• COMMON-MODE RANGE: –16V to +80V
INA200–INA202 are available with three output
voltage scales: 20V/V, 50V/V, and 100V/V, with up to
• HIGH ACCURACY: 3.5% MAX ERROR OVER
500kHz bandwidth.
TEMPERATURE
The INA200, INA201, and INA202 also incorporate an
• BANDWIDTH: 500kHz (INA200)
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
