〇NOTE FOR USE

１． This product is produced with strict quality control, but might be destroyed if used beyond its absolute maximum ratings. Once IC is destroyed,

failure mode will be difficult to determine, like short mode or open mode. Therefore, physical protection countermeasure, like fuse is

recommended in case operating conditions go beyond the expected absolute maximum ratings.

２． 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． BD9240F/FV 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 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．

Under operating CP charge (under error mode) analog dimming and burst dimming are not operate.

１０． By STB and PH voltage, BD9240F/FV are changed to 3 states. Therefore, do not input STB and PH pin voltage between one state and the other

state (0.8½2.0V, VCC×0.5½VCC×0.85 V)

１１． By the DUTY1 pin for setting of Burst dimming Mode, When Burst dimming by DC signal do not input DUTY1 voltage between one state and the

other state

(0.485½0.515V, 1.985½2.015V)

When Burst dimming by PWM signal, set ON time and OFF time of the input PWM pulse signal to more than 30us (Dimming of 0% and Dimming

of 100% are no problem)

１２． The pin connected a connector need to connect to the resistor for electrical surge destruction.

１３． 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.
