■ OPERATIONAL EXPLANATION
<Output Voltage Control>
<Short-Circuit Protection>
The XC6216/XE6216 series includes a current fold-back circuit as a short circuit protection. When the load current reaches
the current limit level, the current fold-back circuit operates and output voltage drops. The output voltage drops further and
output current decreases. When the output pin is shorted, a current of about 30mA flows.
<CE Pin>
The IC’s internal circuitry can be shutdown via the signal from the CE pin with the XC6216/XE6216 series. In shutdown
mode, output at the V
has no pull down resistor so that it will become unstable with the CE pin open. We suggest that you use this IC with either a
V
operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through
current in the IC’s internal circuitry if a medium voltage is applied.
<Thermal Protection>
When the junction temperature of the built-in driver transistor reaches the temperature limit, the thermal shutdown circuit
operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is
released and the IC’s operation is automatically restored because the junction temperature drops to the level of the thermal
shutdown release voltage.
<Minimum Operating Voltage>
For the stable operation of the IC, over 2.0V of input voltage is necessary. The output voltage may not be generated
normally if the input voltage is less than 2.0V.
