(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. All voltage
values are with respect to the network ground terminal unless otherwise noted.

(1) The test was performed on IC terminals that may potentially be exposed to the customer at the product level. The bq2404x IC requires a
minimum of the listed capacitance, external to the IC, to pass the ESD test. The D+ D- lines require clamp diodes such as CM1213A-
02SR from CMD to protect the IC for this testing.
(2) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(3) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
