XC6222 Series
Reverse Current Protection, 700mA High Speed LDO Regulator
ETR0344-003
GENERAL DESCRIPTION
The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed CMOS voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal protection circuit, a reverse current protection circuit and a phase compensation circuit. The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this stand-by mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as a result the VOUT pin will quickly return to the VSS level. Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output current reaches the current limit level or junction temperature reaches the temperature limit. With the reverse current protection function, the reverse current flow is prohibited when VOUT voltage is higher than VIN voltage. The device is optimized for use in backup power circuits.

XC6222 Series
OPERATIONAL EXPLANATION
The voltage divided by two resistors R1 and R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative feedback. The current limit and short protection operate in relation to the level of output current. The thermal protection operates in relation to the level of heat generation. The reverse current protection operates when VOUT voltage is higher than VIN voltage. Further, the IC's internal circuitry can be turned off via the CE pin's signal.

XC6222Aseries The XC6222 needs an output capacitor CL for phase compensation. Values required for the phase compensation are shown in the chart below. If a loss of the capacitance happens, stable phase compensation may not be obtained. Please ensure to use a capacitor which does not depend on bias or temperature too much. For a stable power input, please connect an input capacitor CIN of 1.0F between the VIN pin and the VSS pin. Output Capacitor (CL) Table OUTPUT VOLTAGE (V) 0.8V2.05V 2.1V2.45V 2.5V5.0V OUTPUT CAPACITOR VALUE CL=6.8F (MIN.) CL=4.7F (MIN.) CL=2.2F (MIN.)
The XC6222 series includes reverse current protection to prevent the damage to any connected products such as batteries as a result of current flow from the VOUT pin to the VIN pin. When VIN is smaller than VOUT, the reverse current protection works and suppress the reverse current to 1.5A (MAX.). When VIN is smaller then VOUT, the VOUT pin sink current flows from the VOUT pin to the VSS pin is 95A (TYP.) as the IC operation current. With the XC6222A/C series, when a low level signal is inputted to the CE pin, the sink current of the VOUT pin is minimized to 28A (TYP.). However, with the XC6222B/D series, when a low level signal is inputted to the CE pin, the sink current of the VOUT pin goes through the CL auto discharge circuit to the VSS pin which may result in the IC being damaged. In this case, please do not connect a power supply to the VOUT pin. Please also note when the XC6222A/C series connects external power supply to the VOUT pin, please use under 6.0V. The XC6222 series' fold-back circuit operates as an output current limiter and a short protection circuit for the output pin. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output pin is short-circuited to the VSS pin, the current is decreased to a level of 55mA. When the junction temperature of the built-in driver transistor reaches the temperature limit level (150 TYP.), the thermal shutdown circuit operates and the driver transistor will be turned 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 125 (TYP.) as the thermal shutdown release voltage.

OPERATIONAL EXPLANATION (Continued)
XC6222B/D series can discharge the electric charge stored in the output capacitor (CL), when a low signal to the CE pin, which enables the whole IC circuit to be turned off, is inputted via the N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance value is set at 530(TYP.). The discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting the time constant of the CL auto-discharge resistance value [RDCHG] and the output capacitor value (CL) as (=C x RDCHG), the output voltage after discharge via the N-channel transistor is calculated by the following formula. -t/ V = VOUT(E) x e , or t=In ( V / VOUT(E) ) where V: Output voltage after discharge VOUT (E): Output voltage t: Discharge time : CL auto-discharge resistance RDCHGxOutput capacitor (CL) value C)
The entire XC6222 circuitry can be turned off via the CE pin signal. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. However, with the XC6222B series, the CL auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin. Therefore, time until the VOUT pin reaches the VSS level is shorter. For the XC6222A/B series, the output voltage becomes unstable, when the CE pin is left open. If this CE pin voltage is set with the specified voltage range, the logic is fixed and the IC will operate normally. However, the supply current may increase as a result of shoot-through current in the IC's internal circuitry when a medium voltage is input to the CE pin. With the XC6222C/D series, when the CE pin is left open, output voltage is fixed to VSS level.
NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
