SBOS848B December 2017 – October 2019 INA381
The INA381 supports small-signal bandwidths as high as 350 kHz, and large-signal slew rates of 2 V/µs. The ability to detect rapid changes in the sensed current, as well as the ability to quickly slew the output, makes the INA381 a good choice for applications that require a quick response to input current changes. One application that requires high bandwidth and slew rate is low-side motor control, where the ability to follow rapid changing current in the motor allows for more accurate control over a wider operating range. Another application that requires higher bandwidth and slew rates is system fault detection. The integrated comparator within the INA381 is designed to quickly detect when the sense current is out-of-range, and provide a digital output on the ALERT pin for quicker and faster responses.
