PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
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, determines the measurable input current range of the device and allows for unidirectional or bidirectional sensing as described in Absolute Maximum Ratings. The TMCS1107AxB variants have a zero-current output set by Equation 16, while the TMCS1107AxU devices have a zero-current output voltage set by Equation 17.
These respective reference voltages enable a bidirectional measurable current range for the TMCS1107A2B devices and a unidirectional measurement range for the TMCS1107A2U devices, as shown in Figure 9-9.
