(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

website at www.ti.com.
(2) This data is based on using a 4-layer JEDEC high-K board with the exposed die pad connected to a Cu pad on the board. The board
pad is connected to the ground plane by a 2- × 2-via matrix.
RECOMMENDED OPERATING CONDITIONS
T_A = -40°C to 85°C; typical values at T_A = 25°C and V_(REGIN) = V_BAT = 3.6 V (unless otherwise noted)
