rp115x no. ea - 274 - 1507 08 10 reverse current protection circuit the rp1 15x series include a reverse current protection circuit, which stops the reverse current from v out pin to v dd pin or to gnd pin when v out becomes higher than v in . usually, the ldo using pch output transistor contains a parasitic diode between v dd pin and v out pin. t herefore, if v out is higher than v in , the parasitic diode becomes forward direction. as a result, the current flows from v out pin to v dd pin. the ics of this series switches the mode to the reverse current protection mode before v in becomes lower th an v out by connecting the parasitic diode of pch output transistor to the backward direction, and c onnecting the gate to v out pin. as a result, the pch output transistor is turned off . however, from v out pin to gnd pin, via the internal divider resist o rs, very small current i rev flows. switching to either the normal mode or to the reverse current protection mode is determined by the magnitude of v in voltage and v out voltage. for the stable operation, offset and hysteresis are set as the threshold. t he detec tor threshold is set to v rev_det and the released voltage is set to v rev_rel . therefore, the minimum dropout voltage under the small load current condition is restricted by the value of v rev_rel . f ollowing figures show the diagrams of each mode, and the load characteristics of each mode. when giving the v out pin a constant - voltage and decreasing the v in voltage, the dropout voltage will become lower than v rev_det . as a result, the reverse current protection starts to function to stop the load current. by increasing the dropout voltage higher than v rev_rel , the protection mode will be released to let the load current to flow. if the dropout voltage to be used is lower than v rev_rel , the detection and the release may be repeated. the operating voltage guaranteed level of the reverse current protection circuit is for v out 0.7v. if v in =0v, the reverse current protection mode becomes always active. v dd gnd v out ce vref i out reverse detector + v dd gnd v out ce vref i rev reverse detector + figure 1. normal operation mode figure 2. reverse current protection mode

rp115x no. ea - 274 - 1507 08 12 start - up characteristics constant slope circuit is included in the rp115x series to prevent the overshoot of the output voltage. the start - up time (t on ) is 100 s (typ.). if inrush current increases due to the large capacitance of c out , the operation mode will be shifted from constant slope (cs) mode to constant current (cc) mode. the cc mode maintains a constant level of inrush current. in the cc mode, t on varies according to the size of c out and the amount of load current. start - up t ime and i nrush c urrent estimations start - up time and inrush current in the cs mode and the cc mode can be estimated as follows. ? cs mode start - up t ime : t on = 100s (typ.) inrush c urrent : i rush = c out ? v set / t on + i out * 19 note: if t he result of the above calculation is more than the following values, the operation mo de will be shifted from the cs mode to the cc mode. lcon=?l? 300ma (typ.) lcon=?h? 500ma (t yp .) ? cc mode start - up t ime : t on = c out ? v set / i co *2 0 inrush c urrent : i rush lcon=?l? 300ma (typ.) lcon=?h? 500ma (typ.) *19 i out : when r load is connected to load, i out can be calculated by r load = v set / i out . *2 0 i co : i co is a charge current of c out and can be calculated roughly by i rush i co + i out . rp115x series v dd v out gnd c out ce v fb lcon ce control lcon control v in i rush i co * 2 0 r load i out * 19 circuit e xample note : the lcon pin is only included in rp115l (dfn1216 -8) . rp115h: same electrical characteristics as lcon= ?h ?.
