O

Internal reference signal

Ground input (the thermal pad on the underside of the package) There is an internal electrical connection

between the exposed thermal pad and VSS pin of the device. The exposed thermal pad must be

VSS

11

–

connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as

the primary ground input for the device. VSS pin must be connected to ground at all times.

(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.

(2)

Negative current is defined as current flowing into the BAT pin.

7.2 ESD Ratings

Charged-device model (CDM), per JEDEC specification JESD22-

±250

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with

less than 500-V HBM is possible with the necessary precautions. Pins listed as ±XXX V may actually have higher performance.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with

less than 250-V CDM is possible with the necessary precautions. Pins listed as ±YYY V may actually have higher performance.
