ESD PROTECTION CIRCUIT
Depending upon the function of the pin, different
circuitry is applied. The basic structures are illustrated in
Figure 21.
+Vcc
Although the structures are capable to handle the ESD
stresses (as defined by the JEDEC specifications), no
current or voltage, either DC or AC, beyond the maximum
ratings specifications shall be applied to any pin.

UNDERVOLTAGE LOCKOUT
The VUVLO circuit is used to disconnect the chip when
the input voltage is below the minimum operating value.

Engage the shutdown mode
The system resumes to normal operation when the input
voltage increases by the minimum value plus the hysteresis
as specified in the data sheet.
