●Application Information
When excessive current flows due to output short-circuit or so, ringing occurs because of inductance between power source
lines to IC, and may cause bad influences on IC operations. In order to avoid this case, connect a bypass capacitor across
IN terminal and GND terminal of IC. 1μF or higher is recommended.
Pull up /OC output by resistance 10kΩ to 100kΩ.
Set up value which satisfies the application as CL.
This application circuit does not guarantee its operation.
When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external
components including AC/DC characteristics as well as dispersion 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. And the IN
terminal is used also as power source input to internal control circuit.
When the switch is turned on from EN/EN control input, IN terminal and OUT terminal are connected by an 80mΩ switch.
In on status, the switch is bidirectional. Therefore, when the potential of OUT terminal is higher than that of IN terminal,
current flows from OUT terminal to IN terminal.
Since a parasitic diode between the drain and the source of switch MOSFET is not present in the off status, it is possible
to prevent current from flowing reversely from OUT to IN.
2. Thermal shutdown circuit (TSD)
If over current would continue, the temperature of the IC would increase drastically. If the junction temperature were
beyond 140℃ (typ.) in the condition of over current detection, thermal shutdown circuit operates and makes power
switch turn off and outputs error flag (/OC). Then, when the junction temperature decreases lower than 120℃ (typ.),
power switch is turned on and error flag (/OC) is cancelled. Unless the fact of the increasing chips 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,/EN signal is active).
3. Over current detection (OCD)
The over current detection circuit limits current (ISC) and outputs an error flag (/OC) when current flowing in each switch
MOSFET exceeds a specified value. There are three types of response against over current. The over current detection
circuit works when the switch is on (EN,/EN signal is active).

3-1. When the switch is turned on while the output is in short-circuit status, the switch goes into current limit status
immediately.
3-2. When the output short-circuits or high-current load is connected while the switch is on, very large current flows until
the over current limit circuit reacts. When the current detection limit circuit works, current limitation is carried out.
3-3. 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 the VIN exceeds 2.3V(Typ.). If the VIN drops below 2.2V(Typ.) while
the switch turns on, then UVLO shuts off the power switch. UVLO has hysteresis of 100mV(Typ).
Under voltage lockout circuit works when the switch is on (EN,/EN signal is active).
5. Error flag (/OC) output
Error flag output is N-MOS open drain output. At detection of over current or thermal shutdown, the output level is low.
Over current detection has delay filter. This delay filter prevents instantaneous current detection such as inrush current at
switch on, hot plug from being informed to outside.

●Operational Notes
(1) Absolute maximum ratings
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit
between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such as
adding a fuse, in case the IC is operated over the absolute maximum ratings.
(2) 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.
(3) 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
terminals.
(4) Power supply lines
Design the PCB layout pattern to provide low impedance ground and 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.
(5) Ground Voltage
The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no
pins are at a voltage below the ground pin at any time, even during transient condition.
(6) Short between pins and mounting errors
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation
or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins.
(7) Operation under strong electromagnetic field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
(8) 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.
(9) Regarding input pins 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.

(10) GND wiring pattern
When using both small-signal and large-current GND 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 GND traces of external components do not cause variations on the
GND voltage. The power supply and ground lines must be as short and thick as possible to reduce line impedance.
(11) External 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.
(12) Thermal shutdown circuit (TSD)
The IC incorporates a built-in thermal shutdown circuit, which is designed to turn off the IC when the internal temperature
of the IC reaches a specified value. Do not continue to operate the IC after this function is activated. Do not use the IC in
conditions where this function will always be activated.
(13) Thermal consideration
Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in
actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions (Pc≥Pd).
