lv5603t no.a0611-9/12 stby and ctl pin functions the stby and ctl pins function as active high control inputs. there is no esd protection diode inserted between the v cc line and the stby pin. this means that there is no magnitude relationship between the stby and ctl pin voltage and the v cc voltage. scp pin if of the fb1 to fb6 outputs goes to the high level due to the load being shorted, the scp pin starts a charging operation and the protection circuit will operate if the shorted state is not resolved during the period tscp. (if the protection circuit operates, all outputs ar e turned off.) if the application does not use this protection circuit, the scp pin must be shorted to ground with a line that is as short as possible. t scp = c scp v scp i scp [s] 1.25 [v] t scp scp [v] charging with a current i scp = 4 a short circuit scp operation scp charging operation

lv5603t no.a0611-11/12 setting the oscillator frequency the oscillator frequency is set by the capacitor ct and the re sistor rt connected to the ct pin. the oscillator produces a triangle wave with a frequency determined by ct and rt. the oscillator frequency is expressed by the following equation. f osc = 2.52 1 ct rt [hz] since the actual oscillator frequency will differ somewhat from the value given by the above equation due to overshoot, undershoot, and other factors, it must be verified in the actual end product. the scpout pin this pin reports the scp and ctl states to an external microcontroller or other device. the scpout pin is an open drain output, and thus requires an external pull-up resistor. if this function is not used, the scpout pin should be left open. ctl scp scpo scp operation
