ZHCSJH3A March 2019 – November 2023 INA185
PRODUCTION DATA
One application for the INA185 is to monitor bidirectional currents. Bidirectional currents are present in systems that have to monitor currents in both directions; common examples are monitoring the charging and discharging of batteries and bidirectional current monitoring in motor control. Figure 7-3 shows the device configuration for bidirectional current monitoring. Applying stable REF pin voltage closer to the middle of device supply voltage allows both positive- and negative-current monitoring, as shown in this configuration. Configure the INA185 to monitor unidirectional currents by grounding the REF pin.
