XC6403/XC6404Series

ETR1002_003

High Current, High Speed LDO Regulators, Voltage Detector Function

■GENERAL DESCRIPTION

The XC6403/04 series are highly precise, low noise, 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 5.6V and the LDO output voltage is selectable

within a range of 0.9V to 5.6V (XC6403) 0.9V to 5.1V (XC6404), 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

(XC6403/04 A to C series). The whole IC can be put in to stand-by mode via the CE function with the XC6403/04D series

(semi-custom). In the stand-by mode, power consumption is greatly reduced. The XC6403/04A and B series features the

toggle operation function. The regulator output can be OFF when the XC6403/04B series detects voltage (semi-custom). The

XC6403/04E series can monitor another power source by using the VSEN pin (semi-custom). The XC6403/04F series can

delay the detector output: the delay time can be controlled by the use of an external capacitor (semi-custom).

*The dissipation pad for the

USP-6B package should be

solder-plated in recommended

mount pattern and metal masking

so as to enhance mounting

strength and heat release. If the

pad needs to be connected to other

pins, it should be connected to the

VSS pin.

■OPERATIONAL EXPLANATION

The voltage, divided by resistors R1 & R2 which are connected to the VROUT pin is compared with the internal reference

voltage by the error amplifier. The P-channel MOSFET, which is connected to the VROUT pin, is then driven by the

subsequent output signal. The output voltage at the VROUT pin is controlled & stabilized by negative feedback.

The current limit circuit and short circuit protection operate in relation to the level of output current. Further, the voltage

regulator's internal circuitry can be shutdown via the EN or CE pin's signal.

The series' detector function monitors the voltage divided by resistors R3 & R4 which are connected to the VROUT pin or the

VIN pin or the VSEN pin, as well as monitoring the voltage of the internal reference voltage source via the comparator. The

VDSEN pin has options (please refer to the Selection Guide, item 4). A 'High' or 'Low' signal level can be output from the

VDOUT pin when the VD pin voltage level goes below the detect voltage. The VD output logic has options (please refer to

the Selection Guide, item 5). As VDOUT is an open-drain N-channel output, a pull-up resistor of about 220kΩ is needed to

achieve a voltage output. Because of hysteresis at the detector function, output at the VDOUT pin will invert when the detect

voltage level increases above the release voltage (105% of the detect voltage). Even when the XC6403/04A, B, C, series

are in stand-by mode, the voltage detector function operates and the output voltage at VDOUT will output according to the

voltage level at VDSENSE voltage.

For the XC6403/04A, B, C types, in stand-by, if a voltage of the recovery voltage is present at the VROUT pin (from another

power source), the VDOUT pin will be high impedance mode, and the pull up voltage will be output at VDOUT. By connecting

the Cdelay pin to a capacitor (Cd), the XC6403/04F series can apply a delay time to VDOUT voltage when releasing voltage.

The delay time can be calculated from the internal resistance, Rdelay (2MΩ fixed) and the value of Cd as per the following

equation.

Delay Time = Cdelay x Rdelay x 0.7

With the XC6403/04 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase

compensation circuit is built-in to the regulator. In order to ensure the effectiveness of the phase compensation, we suggest

that an output capacitor (CL) be connected as close as possible, between the output pin (VROUT) and the VSS pin. Please

use an output capacitor (CL) with a capacitance, based on the chart below. We also suggest an input capacitor (CIN) of 1

μF : this should be connected between VIN and VSS in order to stabilize input power source.

The XC6403/04 series regulator offers a combination of current limit and circuit protection by means of a built-in fixed

current limiter circuit and a foldback circuit. When the load current reaches the current limit level, the fixed current limiter

circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output

voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows.

■OPERATIONAL EXPLANATION (Continued)

The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6403/04A, B, C series. In

shutdown mode, output at the VROUT pin will be pulled down to the VSS level via R1 & R2. The whole IC's circuitry can be

shut down via CE pin with the XC6403/04D series and power consumption can be reduced to around 0μA (TYP.). While

the voltage detector is in shutdown mode, the voltage detector output is in a post-detection state. When choosing Detect L,

input current can be set by using the following formula.

Input Current = VIN voltage / Pull-Up Resistance

In stand-by mode, the above input current can be reduced by connecting a pull-up resistor between VROUT and VDOUT.

Note that as the XC6403/04*E to K types of the XC6404A to D series are ' High Active / No Pull-Down' and XC6403/04*R to

U types of the XC6404A to D series are ' Low Active / No Pull-Up', operations will become unstable with the CE pin open

(See the chart below).

We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the EN or CE pin. If this IC is used with

the correct specifications for the EN or CE pin, the IC will operate normally. However, supply current may increase as a

result of through current in the IC's internal circuitry if a voltage other than VIN or VSS is applied.

The XC6403/04 A and B series have a built-in toggle ON/OFF switch which repeats an on/off operation via the EN pin's leading

edge signal when the EN logic is Active HIGH, and via the EN pin's falling edge signal when the EN logic is Active LOW

(Please also refer the figure below). The EN input signal duration should be over 500nsec. If the EN input signal is less than

500nsec, it is possible that the circuit fails to respond and the toggle function does not operate. To operate the toggle function

properly when the EN pin voltage noise is large, a RC filter should be used to reduce the noise in the signal to the EN pin. In

the case where input delay time is required, it is possible to set the time constant by connecting an RC network to the EN pin.

XC6403/XC6404 Series

■OPERATIONAL EXPLANATION (Continued)

<Toggle Operation> (Continued)

For the XC6403/04B series, there are two types of toggle selection; one is a T-type flip-flop (T-FF) used for toggle operation

which can be reset internally by a signal directly from the voltage detector (VIN Sense type only. See also the Selection

Guide). The other type is where the reset is applied internally through a one shot pulse circuit

(VIN, VROUT type only. See also the Selection Guide). The type, which applies the reset directly via the signal from the

voltage detector function, applies the voltage detector comparator's output signal (reset signal) to the reset of T-FF reset, and

turns the VR output OFF when the input voltage decreases below the detect voltage due to battery consumption, etc.. In

order to return the VR output, apply a voltage larger than the release voltage to VIN and input a toggle signal to the T-FF. In

the case where input voltage is below the release voltage, the VR output does not return even though the toggle signal is

input into the T-FF.

The type which applies the reset signal to the T-FF internally via a one-shot pulse circuit changes the voltage detector

comparator output signal to a one-shot signal internally. Like the type which applies the reset directly via the signal from

voltage detector function, this type also applies the reset to the T-FF and sets the VR output to OFF when the input voltage

(VIN Sense type) and output voltage (VROUT Sense type) drop below the detect voltage level. This type can return the VR

output by inputting a toggle signal, even when the Sense pin voltage (VIN or VROUT pin voltage) is below the release voltage.

■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 strengthen VIN and VSS wiring in particular.

3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.

Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as CIN or CL to stabilize

the operation.
