Application Information  
When excessive current flows due to output short-circuit or overload, ringing occurs because of inductance between power  
source line and IC. This may cause bad effects on IC operations. In order to avoid this case, connect a bypass capacitor  
CIN across IN terminal and GND terminal of IC. 1μF or higher is recommended. In order to decrease voltage fluctuations of  
power source line to IC, connect a low ESR capacitor in parallel with CIN. 10μF to 100μF or higher is recommended.  
Pull up /OC output via resistance value of 10kto 100k.  
Set up a value for CL which satisfies the application.  
This system connection diagram does not guarantee operation as the intended application.  
When using the circuit with changes to the external circuit values, make sure to leave an adequate margin for external  
components including static and transitional characteristics as well as the design tolerances of the IC.  
Functional Description  
1. Switch Operation  
IN terminal and OUT terminal are connected to the drain and the source of switch MOSFET respectively. The IN terminal  
is also used as power source input to internal control circuit.  
When the switch is turned on from EN control input, the IN terminal and OUT terminal are connected by a 72m(Typ)  
switch. In ON status, the switch is bidirectional. Therefore, when the potential of OUT terminal is higher than that of the IN  
terminal, current flows from OUT terminal to IN terminal.  
Since the parasitic diode between the drain and the source of switch MOSFET is canceled, current flow from OUT to IN is  
prevented during off state.  
2. Thermal Shutdown Circuit (TSD)  
If over current would continue, the temperature of the IC would increase drastically. If the junction temperature reaches  
beyond 135°C(Typ) during the condition of over-current detection, thermal shutdown circuit operates and turns power  
switch off and outputs error flag (/OC). Then, when the junction temperature decreases below 115°C(Typ), power switch  
is turned on and error flag (/OC) is cancelled. Unless the cause of the increase of the chip’s temperature is removed or  
the output of power switch is turned off, this operation repeats.  
The thermal shutdown circuit operates when the switch is on (EN signal is active).  
3. Over Current Detection (OCD)  
The over current detection circuit (OCD) limits current (ISC) and outputs error flag (/OC) when current flowing in each  
switch MOSFET exceeds a specified value. There are three cases when the OCD circuit is activated. The OCD operates  
when the switch is on (EN signal is active).

(1) When the switch is turned on while the output is in short-circuit status, the switch gets in current limit status  
immediately.  
(2) When the output short-circuits or when high current load is connected while the switch is on, very large current  
will flow until the over-current limit circuit reacts. When this happens, the over-current limit circuit is activated  
and the current limitation is carried out.  
(3) When the output current increases gradually, current limitation does not work until the output current exceeds  
the over-current detection value. When it exceeds the detection value, current limitation is carried out.  
4. Under-Voltage Lockout (UVLO)  
UVLO circuit prevents the switch from turning on until VIN exceeds 2.3V(Typ). If VIN drops below 2.2V(Typ) while the  
switch is still on, then the UVLO will shut off the power switch. UVLO has a hysteresis of 100mV(Typ).  
Under-voltage lockout circuit works when the switch is on (EN signal is active).  
5. Error Flag (/OC) Output  
Error flag output is an N-MOS open drain output. Upon detection of over current or thermal overrun, the output level  
becomes low.  
Over current detection has a delay filter. This delay filter prevents current detection flags from being sent during  
instantaneous events such as surge current due to switching or hot plug. If fault flag output is unused, /OC pin should be  
connected to open or ground line.

Operational Notes  
1. Reverse Connection of Power Supply  
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when  
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power  
supply pins.  
2. Power Supply Lines  
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the  
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog  
block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and  
aging on the capacitance value when using electrolytic capacitors.  
3. Ground Voltage  
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.  
4. Ground Wiring Pattern  
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but  
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal  
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations  
on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.  
5. Thermal Consideration  
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in  
deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when  
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum  
rating, increase the board size and copper area to prevent exceeding the Pd rating.  
6. Recommended Operating Conditions  
These conditions represent a range within which the expected characteristics of the IC can be approximately  
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.  
7. In rush Current  
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush  
current may flow instantaneously due to the internal powering sequence and delays, especially if the IC  
has more than one power supply. Therefore, give special consideration to power coupling capacitance,  
power wiring, width of ground wiring, and routing of connections.  
8. Operation Under Strong Electromagnetic Field  
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.  
9. Testing on Application Boards  
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may  
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply  
should always be turned off completely before connecting or removing it from the test setup during the inspection  
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during  
transport and storage.  
10. Inter-pin Short and Mounting Errors  
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in  
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.  
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment)  
and unintentional solder bridge deposited in between pins during assembly to name a few.  
11. Unused Input Pins  
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and  
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small  
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and  
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the  
power supply or ground line.

Operational Notes - continued  
12. Regarding the Input Pin of the IC  
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them  
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a  
parasitic diode or transistor. For example (refer to figure below):  
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.  
When GND > Pin B, the P-N junction operates as a parasitic transistor.  
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual  
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to  
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should  
be avoided.  
Figure 43. Example of hic IC scture  
13. Ceramic Capacitor  
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with  
temperature and the decrease in nominal capacitance due to DC bias and others.  
14. Thermal Shutdown Circuit(TSD)  
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always  
be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction  
temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below  
the TSD threshold, the circuits are automatically restored to normal operation.  
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no  
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from  
heat damage.  
15. Thermal design  
Perform thermal design in which there are adequate margins by taking into account the power dissipation (Pd) in actual states of  
use.
