The INA300-Q1INA300-Q1 device has an ENABLE terminal that allows the device to be placed into an active enabled state or a low-power disabled state where less than 10 µA is consumed from all terminals. This disable state allows the device to be used in applications where low current consumption is required to extend battery life where constant monitoring is not required. The INA300-Q1 device requires approximately 20 µs to enter the low-power state when the ENABLE terminal transitions from high to low, as shown in Table 7-7. To return to the enabled active state, the INA300-Q1 device requires approximately 300 µs to return to normal operation when the ENABLE terminal transitions from low to high, taking the device out of the low-power state.

The internal counter that determines if the necessary consecutive 10-µs window comparison alert conditions are reached for the 50-µs and 100-µs delay setting is reset when the device is put into a disabled state. When the device is re-enabled, the counter restarts.
