Referring to PIN-SETTING tables Table 2 to 7, users can
search corresponding Vdivider or VIXR according to the
desired function setting combinations. Then SETx external
resistors can be calculated as follows :
IXR
divider
divider
divider
3.2V V
R1
80 A V
R1 V
R2
3.2V V
Richtek provides a Microsoft Excel-based design tool to
calculate the desired PIN-SETTING resistors.
TSEN pin also has function settings except for thermal
monitoring function. It only utilizes divider part of PIN-
SETTING mechanism. The functions TSEN sets include,
zero loadline andDVIDvoltage-compensation. The detailed
operation is described in Thermal Monitoring and Indicator
section.
