Electrical Parameters

DC Parameters
These parameters are static or average values that may be exceeded during switching
transitions (e.g. output current).
Leakage current is strongly dependent on the operating temperature and the voltage
level at the respective pin. The maximum values in the following tables apply under worst
case conditions, i.e. maximum temperature and an input level equal to the supply
voltage.
The value for the leakage current in an application can be determined by using the
respective leakage derating formula (see tables) with values from that application.
The pads of the XC2269I are designed to operate in various driver modes. The DC
parameter specifications refer to the pad current limits specified in Section 4.6.4.
Supply Voltage Restrictions
The XC2269I can operate within a wide supply voltage range from 3.0 V to 5.5 V.
However, during operation this supply voltage must remain within 10 percent of the
selected nominal supply voltage. It cannot vary across the full operating voltage range.
Because of the supply voltage restriction and because electrical behavior depends on
the supply voltage, the parameters are specified separately for the upper and the lower
voltage range.
During operation, the supply voltages may only change with a maximum speed of
dV/dt < 1 V/ms.
During power-on sequences, the supply voltages may only change with a maximum
speed of dV/dt < 5 V/μs, i.e. the target supply voltage may be reached earliest after
approx. 1 μs.
Note: To limit the speed of supply voltage changes, the employment of external buffer
capacitors at pins V_DDPA/V_DDPB is recommended.
