Application Circuit Example
Usage Considerations
power supply or a short-circuit to ground, leading to a damage of the IC. Also, the IC or peripheral parts may be
permanently damaged or emit smoke or fire resulting in injury especially if a power supply pin (V
output pin (AO1, AO2, BO1, BO2) is short-circuited to adjacent or any other pins.
A large current might abruptly flow through the IC in case of a short-circuit across its outputs, a short-circuit to
These possibilities should be fully considered in the design of the output, V
Install this IC correctly. If not, (e.g., installing it in the wrong position,) the IC may be damaged permanently.
Fuses should be connected to the power supply lines.
Note 1: Capacitors for the power supply lines should be connected as close to the IC as possible.
Note 2: The STBY pin must be set Low upon powering on and off the device. Otherwise, a large current might
