Caution 1: 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 and the internal circuitry. 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.  
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in  
deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal  
resistance taken into consideration by increasing board size and copper area so as not to exceed the maximum junction  
temperature rating.  
Caution 3: When IC turns off with an inductive load, reverse energy has to be dissipated in the BV1LB025EFJ-C. This energy can be calculated  
by the following equation:  
1
2
퐵퐴푇  
 
=
퐿퐼푂푈(푆푇퐴푅)2 ×  1  
퐵퐴푇  
 푂푈(퐶퐿)  
Where:  
L is the inductance of the inductive load.  
IOUT(START) is the output current at the time of turning off.  
VOUT(CL) is the output clamp voltage.  
The IC integrates the active clamp function to internally absorb the reverse energy EL which is generated when the inductive load  
is turned off. When the active clamp operates, the thermal shutdown function does not work. Decide a load so that the reverse  
energy EL is active clamp tolerance EAS (refer to Figure 1.) or under when inductive load is used.

IOUT is limited at Over Current Limitation Level (IOUT(LIM)) = 50 A (Typ) when over current is occurred.  
The temperature of Power MOS FET part and the control part in this IC is each TPOWER-MOS, TAMB  
.
When the temperature difference becomes 75 °C (Typ) or more, the output turns OFF. This  
temperature defines as ΔTj Protection Detected Temperature (TDTJD).  
When the temperature difference of TPOWER-MOS and TAMB becomes 45 °C (Typ) or less, the output  
turns automatically ON. This temperature defines as ΔTj Protection Released Temperature (TDTJR).  
The output is turned off when the temperature of the IC reaches Thermal Shutdown Detected  
Temperature (TTSDD) = 180 °C (Typ) or more.  
The output returns to its normal state when the temperature of the IC becomes Thermal Shutdown  
Released Temperature (TTSDR) = 160 °C (Typ) or less.

Operational Notes  
1. Ground Voltage  
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient  
condition.  
2. 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.  
3. Recommended Operating Conditions  
The function and operation of the IC are guaranteed within the range specified by the recommended  
operating conditions. The characteristic values are guaranteed only under the conditions of each item  
specified by the electrical characteristics.  
4. 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.  
5. 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.  
6. Ceramic Capacitor  
When using a ceramic capacitor, determine a capacitance value considering the change of capacitance  
with temperature and the decrease in nominal capacitance due to DC bias and others.  
7. Thermal Shutdown Function (TSD)  
This IC has a built-in thermal shutdown function that prevents heat damage to the IC. Normal operation  
should always be within the IC’s maximum junction temperature rating. If however the rating is exceeded  
for a continued period, the junction temperature (Tj) will rise which will activate the TSD function that will  
turn OFF power output pins. When the Tj falls below the TSD threshold, the circuits are automatically  
restored to normal operation.  
Note that the TSD function operates in a situation that exceeds the absolute maximum ratings and  
therefore, under no circumstances, should the TSD function be used in a set design or for any purpose  
other than protecting the IC from heat damage.  
8. Over Current Protection Function (OCP)  
This IC incorporates an integrated overcurrent protection function that is activated when the load is  
shorted. This protection function is effective in preventing damage due to sudden and unexpected  
incidents. However, the IC should not be used in applications characterized by continuous operation or  
transitioning of the protection function.  
9. Active Clamp Operation  
The IC integrates the active clamp function to internally absorb the reverse energy EL which is generated  
when the inductive load is turned off. When the active clamp operates, the thermal shutdown function  
does not work. Decide a load so that the reverse energy EL is active clamp tolerance EAS (refer to Figure  
1.) or under when inductive load is used.

Operational Notes continued  
10. Negative Current of Output  
When the OUT pin (DRAIN) becomes lower than the GND pin (SOURCE), a current flow from the in pin  
(the IN pin) to the OUT pin (DRAIN) through a parasitic transistor. As shown in Figure 21 when the input  
pin is High, a current flow from a power supply of the connection (MCU, and so on) of the input pin to the  
OUT pin (DRAIN). As shown in Figure 22 when the input pin is Low, a current flow from the GND of parts  
(MCU, and so on) that connected to the input pin to the OUT pin (DRAIN).  
Therefore, set the OUT pin (DRAIN) is -0.3 V or higher. When the OUT pin becomes lower than -0.3V, add  
a restriction resistance 330 Ω or higher to the IN pin. However, set the value of restriction resistance in  
consideration of the voltage descent caused by power supply pin and input pins currents.
