8.4.1 MODE Pin Configuration

The TPS51916 device reads the MODE pin voltage when the S5 signal is raised high and stores the status in a register. A 15-μA current is sourced from the MODE pin during this time to read the voltage across the resistor connected between the pin and GND. Table 2 shows resistor values, corresponding control mode, switching frequency and discharge mode configurations.
