Device-Level Conditions
This section provides the device-level electrical characteristics for the IC.
3.1.1
DC Absolute Maximum Ratings
Table 7 provides the DC absolute maximum operating conditions.
CAUTION
Stresses beyond those listed under Table 7 may cause permanent
damage to the device.
Exposure to absolute-maximum-rated conditions for extended periods
may affect device reliability.
Table 6 gives stress ratings only—functional operation of the device is
not implied beyond the conditions indicated in Table 8.

PSWITCH1
1 VDDIO can be applied to PSWITCH through a 10 k
Ω resistor. This is necessary in order to enter the chip’s firmware recovery
mode. (The on-chip circuitry prevents the actual voltage on the pin from exceeding acceptable levels.)
