3 Description
The INA302 and INA303 (INA30x) devices feature a
high common-mode, bidirectional, current-sensing
amplifier and two high-speed comparators to detect
out-of-range current conditions. The INA302
comparators are configured to detect and respond to
overcurrent conditions. The INA303 comparators are
configured to respond to both overcurrent and
undercurrent conditions in a windowed configuration.
These devices feature an adjustable limit threshold
range for each comparator set using an external limitsetting
resistor. These current-shunt monitors can
measure differential voltage signals on commonmode
voltages that can vary from –0.1 V up to +36 V,
independent of the supply.
The open-drain alert outputs can be configured to
operate in either a transparent mode (output status
follows the input state), or in a latched mode (alert
output is cleared when the latch is reset). The alert
response time for comparator 1 is under 1 μs, and
the alert response for comparator 2 is set through an
external capacitor ranging from 2 μs to 10 s.
These devices operate from a single 2.7-V to 5.5-V
supply, drawing a maximum supply current of 950 μA.
The devices are specified over the extended
operating temperature range of –40°C to +125°C, and
are available in a 14-pin TSSOP package.
