5. Internal digital soft-start.
6. The EXTM1 and EXTM2, SELVTOP1 and SELVTOP2, TXT1 and TXT2, and ADDR0 and ADDR1 pins have 200k internal pull-downs.
7. On exceeding this dynamic back current limit threshold for a period of 100µs, the device enters the dynamic current limit mode, and the BCF I

bit is set. The dynamic back current limit duty during a BCF is ON = 100µs or OFF = 5ms.
tone is ON, the minimum current limit is 50mA lower than the values indicated in the table. While in the dynamic mode of current limit, the trip
level is momentarily increased to 990mA during the 20ms ON time to facilitate recovery from overload conditions.
