●Operational Notes
(1) Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can
break down the device, thus making it impossible to identify the damage mode, such as a short circuit or an open circuit.
If there is any possibility of exposure over the rated values, please consider adding circuit protection devices such as
fuses.
(2) Connecting the power supply connector backward
Connecting of the power supply in reverse polarity can damage the IC. Take precautions when connecting the power
supply lines. An external direction diode can be added.
(3) Power supply lines
Design the PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and supply
line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power supply
terminals to ICs, connect a capacitor between the power supply and GND terminal. When using electrolytic capacitors in
a circuit, note that capacitance values are reduced at low temperatures and over time.
(4) GND voltage
The potential of the GND pin must be minimum potential under all operating conditions.
(5) Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.
(6) Off-leakage at high temperature.
Off-leakage at high temperature may increase because of manufacturing variations.
Design should consider the typical & worst cases shown below.
(7) Inter-pin shorts and mounting errors
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error or if pins are shorted together.
(8) Actions in strong electromagnetic field
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to
malfunction.
(9) ASO
When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO.
(10) Thermal shutdown circuit
The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is
designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or guarantee its operation.
Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit
is assumed.
