GENERAL DESCRIPTION
The XC6801 series is a constant-current/constant-voltage linear charger IC for single cell lithium-ion batteries. The XC6801 includes a reference voltage source, battery voltage monitor, driver transistor, constant-current/constant-voltage charge circuit, overheat protection circuit and phase compensation circuit. The battery charge termination voltage is internally set to 4.2V ±0.7% and the trickle charge voltage and accuracy is 2.9V ±3%. In trickle charge mode, a safe battery charge is possible because approximately only 1/10 of the full charge current is supplied to the battery. As it is possible to select a highly accurate charge current of either 100mA (MAX.) for L level input to the LIM pin or 500mA (MAX.) for H level, the series is ideal for applications where the charge is from USB. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state via connection to an external LED.

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.

GENERAL DESCRIPTION
The XC6405 series are precise, low noise, high speed, high current, positive voltage low dropout regulators with built-in voltage detector. They are fabricated using Torex’s CMOS process. Performance features of the series includes high ripple rejection and low dropout voltage, and the series features a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor.
Detect voltage is selectable in 100mV increments within the range of 0.9V to 5.5V and the LDO output voltage is selectable within a range of 0.9V to 5.1V, also in 100mV increments.
The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The current limiter's foldback circuit also operates as a short circuit protection for the output current limiter and the output pin. The series provides options to the user to select from a variety of circuit features, such as detector monitoring, detector output logic, CE and EN pin input logic, internal pull-up / down resistance, and power ready. The IC's internal regulator circuit can be placed in stand-by mode via the EN function (XC6405 A to C series). The whole IC can be put in to stand-by mode via the CE function with the XC6405D series (semi-custom). In the stand-by mode, power consumption is greatly reduced. The XC6405 A and B series features the toggle operation function. The regulator output can be OFF when the XC6405B series detects voltage (semi-custom). The XC6405E series can monitor another power source by using the VSEN pin (semi-custom).

The XC6225 series is a high accuracy, low noise, and low dropout CMOS LDO regulator. The series includes a reference voltage source, an error amplifier, a driver transistor, a current limiter, and a phase compensation circuit.
The CE function enables the entire circuit to be turned off by a low level input signal to the CE pin. In this stand-by state, the XC6225B series can discharge the electric charge stored at the output capacitor through the internal auto-discharge switch, and as a result the VOUT pin quickly returns to the VSS level.

GENERAL DESCRIPTION
The XCM406 series is a high current, dual LDO regulator in an ultra small USP-12B01 package which measures just 2.8mm x 2.8mm. The IC is basically two XC6210 high speed CMOS LDOs which are precise, low noise, high current, regulators consisting of a voltage reference, an error amplifier, a current limiter and phase compensation circuit plus a driver transistor.

The series can be used with low ESR ceramic capacitors and output voltages are selectable in 0.1V increments within a range of 0.8V to 5.0V per channel. The fold-back current limit circuit also operates as the output current limiter and the output pin protector.

GENERAL DESCRIPTION
 The XC9128/XC9129 series are synchronous step-up DC/DC converters with a 0.2Ω (TYP.) N-channel driver transistor and a synchronous 0.2Ω (TYP.) P-channel switching transistor built-in.
A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors.
With a high switching frequency of 1.2MHz, a small inductor is selectable making the series ideally suited for applications requiring low profile or space saving solutions.
With the MODE pin, the series provides mode selection of PWM control or PFM/PWM automatic switching control.
In the PWM/PFM automatic switching mode, the series switches from PWM to PFM to reduce switching loss when load current is small.
When load current is large, the series switches automatically to the PWM mode so that high\ efficiency is achievable over a wide range of load conditions.
The series also provides small output ripple from light to large loads by using the built-in circuit which enables the smooth transition between PWM and PFM.
When a voltage higher than the input voltage is applied to the output during shut-down, the input and the output become isolated making it possible for the IC to work in parallel with the likes of an AC adaptor.
