Pin Function Description Pin Number 1, 2, 5, 6, 15, 16, 19, 20 Pin Name VBAT Pin Function Supply Voltage Definition These are the power supply pins of the device. These pins are directly connected with the lead frame of the package and are tied to the drain of the switching MOSFET. These pins can be directly connected to the battery voltage. In addition to their supply function, these pins participate to the thermal behavior of the device in conducting the heat from the switching MOSFET to the printed circuit board. Pins 3 and 4 are the output 1 pins. Pins 17 and 18 are the output 2 pins. They are directly connected to the source of...
