TOREX XC6414

XC6413/XC6414 Series
ETR1004-001
High Current, High Speed LDO Regulators, Voltage Detector Function
■ GENERAL DESCRIPTION
The XC6413/14 series are highly precise, low noise, positive voltage LDO regulators with voltage detector manufactured using
CMOS processes. Performance features of the series includes high ripple rejection and lo dropout 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 a range of 0.9V ~ 6.0V and VR output voltage is selectable within a range of 0.9V ~
5.5V. 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 protect fro 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. The IC’s internal regulator circuit can be placed in stand-by mode via the EN function with the
XC6413/14A to C series. The whole IC can be placed in stand-by mode via the CE function with the XC6413/14D series
(semi-custom). In the stand-by mode, power consumption is greatly reduced. The XC6413/14A and B series features a
toggle operation function. The regulator output can be OFF when the XC6413/14B series detects voltage (semi-custom).
The XC6413/14E series can monitor another power source by using the VSEN pin (semi-custom). The XC6413/14F series
can delay the detector output. 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 (No. 5) pin.

■OPERATIONAL EXPLANATION
<Output Voltage Regulator Control>
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.
<Detector Function with the XC6413/14 Series>
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 XC6413/14A, 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 XC6413/14A, 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 XC6413/14F series can apply a delay time to
VDOUT voltage when releasing voltage. The delay time can be calculated from the internal resistance, Rdelay (2MΩ, TYP.,
fixed) and the value of Cd as per the following equation.
Delay Time = Cdelay×Rdelay×0.7

<Low ESR Capacitors>
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.

<Current Limiter, Short-Circuit Protection>
The XC6413/14 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.
<EN / CE Pin>
The IC's internal regulator circuitry can be shut down via the signal from the EN pin with the XC6413/14A, 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 XC6413/14D 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

XC6413/XC6414 Series
■OPERATIONAL EXPLANATION (Continued)
<EN / CE Pin (Continued)>
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 XC6413/14*E to K types of the XC6413/14A to D series are ' High Active / No Pull-Down' and XC6413/14*R
to U types of the XC6413/14A to D series are ' Low Active / No Pull-Up', operations will become unstable with the CE pin
open (See the chart below).

(*A~D Series)
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.
<Toggle Operation>
The XC6413/14 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 HIGH active, and via the EN pin's falling edge signal when the EN logic is LOW active
(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.
XC6413/14B series can reset FF (flip flop), used for the toggle operation, internally by using a signal of the detector function.
The signal of the detector function resets FF after converted to 1 shot signal in the IC. The regulator block start to output
when a signal is given via the EN pin again.

■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.
