Operational Notes
1)
Absolute Maximum Ratings
Operating the IC over the absolute maximum ratings may damage the IC. In addition, it is impossible to predict all
destructive situations such as short-circuit modes or open circuit modes. Therefore, it is important to consider circuit
protection measures, like adding a fuse, in case the IC is expected to be operated in a special mode exceeding the
absolute maximum ratings.
2)
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.
3)
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.
4)
Source (GND) Voltage
The voltage of the Source (GND) 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.
5)
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).
Package Power dissipation : Pd (W)=(Tjmax-Ta)/θja
Power dissipation
: Pc (W)=(Vcc-Vo)×Io+Vcc×Ib
Tjmax : Maximum junction temperature=150℃, Ta : Peripheral temperature[℃] ,
θja : Thermal resistance of package-ambience[℃/W], Pd : Package Power dissipation [W],
Pc : Power dissipation [W], Vcc : Input Voltage, Vo : Output Voltage, Io : Load, Ib : Bias Current
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)
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 175°C (25°C hysteresis). It is not designed to protect the IC from damage or guarantee
its operation. 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.
8)
Over voltage protection (active clamp)
There is a built-in over voltage protection circuit (active clamp) to absorb the induced current when inductive load is off
(Power MOS = off). During active clamp and when IN=0V, TSD will not function so keep IC temperature below 150°C.
9)
Over current protection circuit (OCP)
The IC incorporates an over-current protection circuit that operates in accordance with the rated output capacity. This
circuit protects the IC from damage when the load becomes shorted. It is also designed to limit the output current
(without latching) in the event of more than 1.5A (typ) flow, such as from a large capacitor or other component
connected to the output pin. This protection circuit is effective in preventing damage to the IC in cases of sudden and
unexpected current surges. The IC should not be used in applications where the over current protection circuit will be
activated continuously.
10)
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.
11) 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.

BD1LB500 Series (BD1LB500EFJ-C BD1LBU50EFJ-C BD1LB500FVM-C)
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.

12)
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.
13)
Back electromotive force (BEMF)
There is a possibility that the BEMF is changed by using the operating condition, environment and the individual
characteristics of motor. Please make sure there is no problem when operating the IC even though the BEMF is
changed.
14)
Rush Current
When power is supplied to the IC, inrush current may flow instantaneously. It is possible that the charge current from
the parasitic capacitance of the internal logic may be unstable. Therefore, give a special consideration with the power
coupling capacitance, power wiring, width of GND wiring, and routing of connections.
15)
TAB
IC’ sub is already connected to TAB, please short TAB to External GND.
