To avoid ground shift problems due to the high currents in the switches, separate AGND (pin 10) from PGND1
(pin 20), PGND2 (pin 14), PGND3 (pin 25), PGND4 (pin 2), and PGND5/7 (pin 37). The reference GND for all
control signals, such as XSLEEP, is AGND. The power switches inside the IC are connected to PGND1, PGND2,
PGND3, PGND4, and PGND5/7. Both grounds must be connected on the printed circuit board (PCB) (ideally at
only one point).
