grounded at only one contact point. Take the heat dissipation into consideration when designing the board.
When in controlling the setting pins for each mode by SW, those pins should be pulled up to power supply
like V
Utmost care is necessary in the design of the output line, V
due to short-circuit between outputs, to supply, or to ground.
Especially for those pins that are connected to power supply and get a large current flow (such as V
OUT and GND), they should be properly wired; otherwise troubles including destruction may occur to this IC.
If the logic input pins are not wired properly, malfunction that would destroy the IC may occur due to a large
current exceeding the absolute maximum ratings.
Care should be taken in the design of board layouts and implementation of the IC.
