The INA302A2QPWRQ1 devices have a high common-mode, bi-directional, current-sense amplifier and two high-speed comparators for detecting out-of-range current conditions.The INA302-Q1 comparator is configured to detect and respond to overcurrent conditions.The INA303 -Q1 comparator is configured to respond to overcurrent and undercurrent conditions in a windowed configuration. These devices have adjustable limit threshold ranges for each comparator setting using external limit setting resistors. These current shunt monitors measure differential voltage signals over a common mode voltage range of -0.1V to +36V independent of the power supply. In addition, these devices will withstand common mode voltages up to 40V.
The open-drain alarm outputs can be configured to operate in either transparent mode (output state is aligned with input state) or latched mode (alarm output clears on latched reset). The alarm response time for Comparator 1 is less than 1µs, while the alarm response time for Comparator 2 is set by an external capacitor and ranges from 2µs to 10s.
The device is powered from a single 2.7V to 5.5V supply and consumes a maximum supply current of 950µA. The device has an extended rated operating temperature range of -40°C to +125°C and is available in a 14-pin TSSOP package.
