SBOS825D September 2019 – July 2021 TMCS1101
The device has an internal resistor divider from the analog supply VS that determines the zero-current output voltage, VOUT,0A. This zero-current output level along with sensitivity determine the measurable input current range of the device, and allows for unidirectional or bidirectional sensing, as described in the Section 7.1 table. The TMCS1101AxB variants have a zero-current output set by Equation 16, while the TMCS1101AxU devices have a zero-current output voltage set by Equation 17.
These respective reference voltages enable a bidirectional measurable current range for the TMCS1101A2B devices and a unidirectional measurement range for the TMCS1101A2U devices, as shown in Figure 9-14.
