XC8102 Series
Load Switch with Low On-Resistance
www..com
ETR2502-006a
GENERAL DESCRIPTION
The XC8102 series is a low ON resistance load switch IC with ON/OFF control and output current protection which integrates a P-channel MOSFET. By connecting the XC8102 to the output pin of a step-down DC/DC converter, the CE pin controls ON/OFF for each distribution switch to deliver power per requirements and maximize total power efficiency. As a result, the XC8102 helps to extend battery life and product operation time. The series contains a current limit and protection circuit so these are not required externally unlike discrete circuit solutions where MOSFETs and resistors are used. When a low signal is input to the CE pin, the series enters stand-by mode. Even where a load capacitor is connected to the output pin during stand-by, the electric charge stored at the load capacitor is discharged through the internal switch. As a result, the VOUT pin voltage falls quickly to the VSS level. The series contains over current protection with fold-back current circuitry which operates as over current protection and short circuit protection for the output pin.

OPERATIONAL EXPLANATION
The XC8102 enables an output P-channel MOSFET switch and the IC internal circuitry to turn off by the signal to the CE pin. In the shutdown mode, the VOUT pin will be pulled down to the VSS by the CL auto-discharge function. The output voltage becomes unstable when the CE pin is opened. If the input voltage to the CE pin is within the specified threshold voltages, the logic is fixed and the XC8102 will operate normally. However, supply current may increase as a result of the shoot-through current of internal circuitry when the medium level voltage is input to the CE pin.
Input/Output Capacitor The XC8102 works well without an input and output capacitors. Also, an output capacitor of the power source can be used as an input capacitor of the XC8102 and a bypass capacitor of the driving IC can be used as an output capacitor of the XC8102.
The XC8102AA contains a CL auto-discharge resistor and an N-channel transistor between the VOUT pin and the VSS pin. The device quickly discharge the electric charge in the output capacitor (CL) when a low signal to the CE pin is input to turn off a whole IC circuit. The CL auto-discharge resistance is set at 480 (VOUT=4.0V TYP. @ VIN=4.0). Discharge time of the output capacitor (CL) is determined by a CL auto-discharge resistor value (Rdischg) and an output capacitor value. Time constant is defined as ( = C x Rdischg). Output voltage after starting discharge can be calculated by the following formula. V = VOUT x e -t/ , or t= In (VOUT / V)
V: Output voltage after starting discharge, VOUT: Output voltage, t : Discharge time, : Output discharge resistor value Rdischg Output capacitor (CL) value C
The XC8102 series contains a constant current limiter and fold-back current circuitry. The constant current limiter operates to limit output current and the fold-back current circuitry operates as short circuit protection for the output pin. When the load current reaches the limit current, the constant current limiter operates and the output voltage drops. The output voltage further, then the fold-back current circuitry operates to decrease the output current. When the output pin is short-circuited to the ground, the output current drops and maintains a flow about 30mA.
NOTES ON USE
1. 2. 3. 4. Please use this IC within the stated absolute maximum ratings. Operation beyond these limits may cause degrading or permanent damage to the device. The X8102 goes into an undefined operation when the CE pin is left open. The CE pin shall be tied to low or high level. VOUT pin voltage should not be applied beyond the VIN pin voltage. The IC may get damage due to the reverse current toward the VIN pin. Current limit function is integrated. However, power dissipation may be beyond the limit before starting a fold-back current protection when used in high temperature. For the power dissipation of each package, please refer to the graphs of Package Power vs. Operating Temperature in page 15 to 18.
