○ Cautions on use
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 devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any
over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as
fuses.
2.
PGND potential
Ensure a minimum GND pin potential in all operating conditions. In addition, ensure that no pins other than the GND pin
carry a voltage less than or equal to the GND pin, including during actual transient phenomena.
3.
Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating
conditions.
4.
Protect circuit
The IC does not incorporate built-in malfunction protection such as overcurrent protection, short detection, or thermal
shutdown circuitry. For this reason, the IC may be damaged if it is shorted or subjected to a load that exceeds the
package power. The design of peripheral application circuits should reflect these potential risks.
5.
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 positive and ground power supply terminals are reversed. The IC may also be damaged if pins are
shorted together or are shorted to other circuit’s power lines.
6.
Common impedance
The power supply and ground lines must be as short and thick as possible to reduce line impedance. Fluctuating
voltage on the power ground line may damage the device.
7.
Backside copper foil
Connect to PGND pin for protection of malfunction.
8.
Thermal shutdown
there is a temperature protection circuit in the body ,for protect from heating damage, When thermal circuit
moved, output is OFF condition. However it would be fixed automatically, If it return to regular temperature.
9.
Voltage of START pin
The threshold voltages of START pin are 2.0V. STB state is set below 0.4V while action state is set beyond
2.0V.The region between 0.4V and 2.0V is not recommended and may cause improper operation.
