10.2.5.2 Design Procedure
The R(REFHI) and R(REF) reference resistors set the current. R(REF) by itself sets the tail current. R(REF) and R(REFHI) together set the stop current. In different applications, reference resistors can be set to different values for different devices to achieve current flexibility. In this document, for simplicity, the application sets the same reference current in both devices.
