A Function 4/4 〇NOTE FOR USE １． When designing the external circuit, including adequate margins for variation between external devices and the IC.Use adequate margins for steady state and transient characteristics. ２． Recommended Operating Range The circuit functionality is guaranteed within of ambient temperature operation range as long as it is within recommended operating range. The standard electrical characteristic values cannot be guaranteed at other voltages in the operating ranges, however, the variation will be small. ３． Mounting failures, such as misdirection or miscounts, may harm the device. ４． A strong electromagnetic field may cause the IC to malfunction. ５. The GND pin should be the location within ±0.3V compared with the PGND pin ６． The BD9882F and BD9882FV incorporate a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is designed only to shut the IC off to prevent runaway thermal operation. 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 the thermal shutdown circuit is assumed. ７． Absolute maximum ratings are those values that, if exceeded, may cause the life of a device to become significantly shortened. Moreover, the exact failure mode caused by short or open is not defined. Physical countermeasures, such as a fuse, need to be considered when using a device beyond its maximum ratings. ８．About the external FET, the parasitic Capacitor may cause the gate voltage to change, when the drain voltage is switching. Make sure to leave adequate margin for this IC variation. ９． On operating Slow Start Control (SS is less than 2.2V), It does not operate Timer Latch. １０． By STB voltage, BD9882F and BD9882FV are changed to 2 states. Therefore, do not input STB pin voltage between one state and the other state (0.8～1.8V). １１．The pin connected a connector need to connect to the resistor for electrical surge destruction. １２．This IC is a monolithic IC which (as shown is Fig-1)has P+ substrate and between the various pins. A P-N junction is formed from this P layer of each pin. For example, the relation between each potential is as follows, ○(When GND > PinB and GND > PinA, the P-N junction operates as a parasitic diode.) ○(When PinB > GND > PinA, the P-N junction operates as a parasitic transistor.) Parasitic diodes can occur inevitably in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits as well as operation faults and physical damage. Accordingly you must not use methods by which parasitic diodes operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin.
