(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.
(2) The negative spike less than –5 V and narrower than 50-ns width should not cause any problem.
(3) May shut down due to regulator OCP.

(1) Deep Sleep shuts down majority of the device and runs minimal circuits (internal bias circuits and the nWAKEUP pin). Deep Sleep is
entered by writing 1 to Setup Register, Bank 1, Bit 11. Device is restarted by pulling nWAKEUP pin low or power cycling V_M. Deep
Sleep functionality only available for V_M > Vth_VM+.
(2) A_CONT is filtered for both high and low levels.
