Note: Stresses beyond the values listed may cause a permanent damage to the device. The device may not operate under these conditions,

but it will not be destroyed.

Note 1: JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process.

Note 2: JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process.

Note 1: EN input can be driven even from low supply voltage controller due to low 0.9V VIH min threshold.

Note 2: EN input has active pull-down by 400k

Ω which is disabled to save current when inputs are pulled high.
