TOREX XC6408DD10MR-G

XC6408 Series
ETR0331-004a
28V Operation Voltage Regulator with Voltage Detector
■GENERAL DESCRIPTION
The XC6408 series is a positive voltage regulator IC manufactured using CMOS process with 28V operation voltage. The series
consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit
plus a driver transistor. The output voltage and the detect voltage are user selectable in 0.1V increments. The over current
protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current
reaches current limit level or the junction temperature reaches temperature limit level. The XC6408D series monitors its output
voltage and provides reset signal if its output voltage falls below the pre-set voltage. This reset time (release delay time) can be
set by an external capacitor. The XC6408E series monitors an external power supply and enables the output to be turned off
and the IC becomes a stand-by mode.

■PIN CONFIGURATION
NC
* The dissipation pad for the USP-6C package should be solder-plated in recommended mount
pattern and metal masking 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
XC6408 D Type
XC6408 E Type
<Voltage Regulator>
The voltage divided by resistors R11 & R12 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 and stabilized by a system of negative feedback. The current limit circuit, short protect circuit
and thermal protection circuit operate in relation to the level of output current and heat generation. For the XC6408E,
regulator operation returns active state when VSEN pin voltage rises higher than the release voltage (*when VSEN pin voltage
is higher than detect voltage + hysteresis voltage).
<Limit Current, Short-Circuit Protection>
The XC6408 series includes a current fold-back circuit as a short circuit protection. When the load current reaches the
current limit, the current fold-back circuit starts to operate. As a result, the output voltage drops further and output current
decreases. When the VROUT pin is short-circuited, a flow current minimizes to around 30mA.
<Thermal Shutdown>
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 set to 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 the thermal shutdown release voltage.
<Minimum Operating Voltage>
For the stable operation of the IC, over 2.0V of input voltage is necessary. The output voltage may not be generated
normally if the input voltage is less than 2.0V.

■ OPERATIONAL EXPLANATION (Continued)
<Voltage detector>
(XC6408D and XC6408E)
The detector function of the XC6408D/E series has hysteresis, and when the detected voltage rises higher than the release
voltage (typically about 105% of the detect voltage), the output of the VDOUT pin inverts.
(XC6408D)
The detector function of the XC6408D series is connected to the VROUT pin inside the IC and detects the VROUT output
voltage.
The voltage divided by the detector’s internal resistance which is connected to the VROUT pin is compared to the IC internal
reference voltage, and if the voltage of the VROUT pin falls below the threshold value, low level signal is output from VDOUT.
A capacitor (Cd) can be connected to the Cd pin to add a delay time to the output signal of the VDOUT pin at voltage release.
The delay time is determined by the constant current value determined by the internal current generator circuit, and the Cd
capacitance value. The relationship between the Cd capacitance value and the delay time is shown below.
(XC6408E)
The detector function of the XC6408E series detects the VSEN pin voltage.
The voltage divided by the detector internal resistance that is connected to the VSEN pin is compared to the IC internal
reference voltage, and if the voltage of the VSEN pin falls below the threshold value, low level signal is output from VDOUT.

■ 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． The power input pin voltage will falls down because of a resistance between power supply and power input pin and shoot
through current when IC operates. At this time, if the power input pin voltage is lower than operating voltage range, the IC
may cause device malfunction.
3. Please note if the power input pin voltage will fluctuated, the IC may cause device malfunction.
4. If assumed the power input pin voltage falls suddenly (e.g. falls from 28.0V to 0V) at release operation when VD delay
capacitor pin is connected to a capacitor, please connect a schottky barrier diode between the power input pin and delay
capacitance pin. Please refer below; (XC6408D).
5. The VDOUT output is configured as N-ch open drain, so please use a pull-up resistance more than 100kΩ for connecting to
the output pin.
* When the pull-up resistor connects to another power supply, high level value will be equal to the voltage which the pull-up
resistor is connected.
6. If the input voltage fluctuates more than 1.5V in the speed higher than 100mV/μs, the output voltage may fluctuate widely.
In this case, one capacitor should be added between VIN-VSS to adjust the input fluctuation speed less than 100mV/μs.
7. For a delay capacitor pin of the XC6408D is designed in high impedance. When this pin is left open for use, the IC may
get noise. It is recommended that a capacitor more than 3pF is connected to the delay capacitor pin.
8. Phase compensation is performed in the XC6408 inside. Therefore, an abnormal oscillation does not occur even if there is
no output capacitor CL. An input capacitor CIN around 0.1μF~1.0μF between the VIN pin and the VSS pin is required for
input stability. Also, the output voltage fluctuation such as under shoot or over shoot, which occurs because of the load
change can be controlled by placing the output capacitor CL around 0.1μF~1.0μF between the VROUT pin and VSS pin.
The input capacitor (CIN) and the output capacitor (CL) should be placed to the IC as close as possible with a shorter wiring.
