13. DC Characteristics
Note: Values in this data sheet are design goals and are subject to change based on the results of device characterization.
13.1 Absolute Maximum Ratings
Caution! The absolute maximum ratings in Table 21 indicate levels where permanent damage to the device can occur, even if these
limits are exceeded for only a brief duration. Functional operation is not guaranteed under these conditions. Operation at absolute
maximum conditions for extended periods can adversely affect long-term reliability of the device.

a. VBAT is the main power supply of the chip.
b. Voltage transients up to 6.0V for up to 10 seconds, cumulative duration over the lifetime of the device, are allowed. Voltage transients as high
as 5.5V for up to 250 seconds, cumulative duration over the lifetime of the device, are allowed.
c. Duration not to exceed 25% of the duty cycle.
