Charge Pump Output Current Limit
The device also limits the charge pump current at the
VOUT pin (typically 300mA).
LDO Current Limit
The device limits the output currents of LDO1 and LDO2
to help prevent it from overheating and to protect the
loads. The minimum limit is 200mA, so load current
greater than the rated 100mA can be used with degraded
accuracy and larger dropout without tripping the current
limit.
Applications Information (continued)
LED Float Detection
Float detect is a fault detection feature of the LED current
sink outputs. If an output is programmed to be enabled
and an open circuit fault occurs at any current sink output,
that output will be disabled to prevent a sustained output
OVP condition from occurring due to the resulting open
loop. Float detect ensures device protection but does
not ensure optimum performance. Unused LED outputs
must be disabled to prevent an open circuit fault from
occurring.
