Logic Output. When high, indicates lower clamp active. See the Clamp Function section.
Description
Upper Comparator Threshold Voltage Input, CPH > CPL.
Lower Comparator Threshold Voltage Input, CPL < CPH.
Digital Supply Voltage.
Logic Output. When high, indicates MEASVOUT or MEASIOUT > CPH.
Logic Output. When high, indicates MEASVOUT or MEASIOUT < CPL.
Logic Input. Used to initiate comparator sampling and update CPOH and CPOL.
Digital Ground.
Logic Output. When high, indicates upper clamp active. See the Clamp Function section.
Logic Output. When high, indicates current range Mode 4 is enabled. May be used to drive external relay or
switch. See the High Current Ranges section.
Logic Output. When high, indicates current range Mode 5 is enabled. May be used to drive external relay or
switch. See the High Current Ranges section.
Active Low MEASOUT Enable.
Active Low Logic Input. The device is selected when this pin is low. See the Interface section.
Active Low Logic Input. Used in conjunction with CPCK and CS to configure the device for different
configurations. Rising edge of STB triggers sequence inputs. See the Interface section.
Logic Input. Used in conjunction with AC1 to select one of three external compensation capacitors.
See the Force Control Amplifier section.
Logic Input. Used in conjunction with AC0 to select one of three external compensation capacitors.
See the Force Control Amplifier section.
Logic Input. Used in conjunction with AM1 and AM0 to select one of six current ranges or to enable standby
mode. See the Current Ranges section.
Logic Input. Used in conjunction with AM2 and AM0 to select one of six current ranges or to enable standby
mode. See the Current Ranges section.
Logic Input. Used in conjunction with AM2 and AM1 to select one of six current ranges or to enable standby
mode. See the Current Ranges section.
Logic Input. When high, device is in standby mode of operation. See the Standby Mode section.
