4/4 rev. a cautions on use 1. absolute maximum ratings an excess in the absolute maximum rating s, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify break ing 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 conditi ons. 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 malf unction protection such as overcurrent protection, short detection, or thermal shutdown circuitry. for this reason, the ic may be damaged if it is shorted or subjecte d to a load that exceeds the package power. the design of peripheral applicatio n 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 term inals 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 th ick 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 prot ection 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 re commended and may cause improper operation.
