BD2042AFJ/ bd2052afj has dual t hreshold temperature for its thermal shutdown. since thermal shutdown works at a lower junction temperature, only the switch with an over current state turns off whenever over current occurs and outputs a n error flag . thermal shutdown detection has hysteresis. therefore, when the junction temper ature goes down, switch turns on and error flag is cancelled. unless the increase of the chips temperature is removed or the output of power switch is turned off , this operation repeats . 22 / 31 www.rohm.com ? 2013 rohm co., ltd. all rights reserved. tsz22111 ? 15 ? 001 tsz02201 - 0e3e0h300240 -1-2 21.aug.2014 rev.003 downloaded from: http:///

(1) when the switch is turned on while the output is in short - circuit status, the switch goes into current limit status immediately. (2) when the ou tput short - circuits or high - current load is connected while the switch is on, very large current fl ows until the over current limit circuit reacts. when the current detection an d limit circuit works, current limitation is carried out. (3) when the output curre nt increases gradually, current limitation does no t work until the output current exceeds the over current detection value. when it exceeds the detection value, curre nt limitation is carried out. 4. under v oltage l ockout (uvlo) uvlo circuit turns off the sw itch to prevent malfunction w hen the supply voltage is below the uvlo threshold level, the uvlo circuit works when either of two control signals is active. BD2042AFJ/bd2052afj uvlo circuit prevents the switch from turning on until the v in exceeds 2.3v (typ ). if the v in drops below 2.2v(typ) while the switch is on, then uvlo shuts off the switch. uvlo has hysteresis of 100mv(typ) . 5. error flag (/oc) output error flag output is an n - mos open drain output. at detection of over current limit and thermal shutdown, /oc outputs a low lev el signal. e rror flag output (/oc) at over current detection has a delay filter . this delay filter prevents instantaneous current detection such as in rush current at switch on, or applying external power supplies. if fault flag output is unused, /oc pin should be connected to open or ground line. output shortcircuit thermal shut down v ctrl v en v out i out v flag v /oc delay figure 61 . bd6516f/ bd65 17f/BD2042AFJ/ bd2052afj over current detection , thermal shutdown timing diagram (v ctrl , v /en of bd6517f/BD2042AFJ active low) v ctrl v out i out v flag output short circuit thermal shut d own flag output delay v ctrl v en v out i out v flag v /oc 23 / 31 www.rohm.com ? 2013 rohm co., ltd. all rights reserved. tsz22111 ? 15 ? 001 tsz02201 - 0e3e0h300240 -1-2 21.aug.2014 rev.003 downloaded from: http:///

bd651 6f bd6517f bd20 42afj bd2052 afj data s heet operational notes - continued 11. unused inpu t pins input pins of an ic are often connected to the gate of a mos transistor. t he gate has extremely high impedance and extremely low capacitance. if left unconnected, the electric field from the outside can easily charge it. the small charge acquired in this way is enough to produce a significant effect on the conduction through t he transistor and cause unexpected operation of the ic. so unless otherwise specified, unused inpu t pins should be connected to the power supply or ground line. 12. regarding the i nput p in of the ic this monolithic ic contains p+ isolation and p substrate layers between adjacent elements in order to keep them isolated. p - n junctions are formed at the intersection of the p layers with t he n layers of other elements, creating a parasi tic diode or transistor. for example (refer to figure below): when gnd > pin a and gnd > pin b, the p - n junction operates as a parasitic diode. when gnd > pin b, the p - n junction operates as a parasitic transistor. parasitic diodes inevitably occur in t he structure of the ic. the operation of parasitic diodes can result in mu tual interference among circuits, operational faults, or physical damage. therefore , conditions that cause these diodes to operate, such as applying a voltage lower than the gnd voltage to an input pin (and thus to the p substrate) should be avoided. fig ure 63 . example of monolithic ic structure 13. ceramic capacitor when using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperatur e and the decrease in nominal capacitance due to dc bias and others. 14. thermal s hutdown circuit(tsd) this ic has a built - in thermal shutdown circuit that prevents heat damage to the ic. normal operat ion should always be within the ics power dissipation rating. if however the rating is exceeded for a continued period, the junction temperature (tj) will rise which will activate the tsd circuit t hat will turn off all output pins. when the tj falls below the tsd threshold, the circuits are automatically restored to normal operat ion. note that the tsd circuit operates in a situation that exceeds the absol ute maximum ratings and therefore, under no circumstances, should the tsd circuit be used in a set design or for any purpose other than protecting the ic from he at damage. 15. thermal design perform thermal design in which there are adequate margins by taking into account t he p ower dissipation (pd) in actual states of use. n n p + p n n p + p substrate gnd n p + n n p + n p p substrate gnd gnd parasitic elements pin a pin a pin b pin b b c e parasitic elements gnd parasitic elements c be transistor (npn) resistor n region close-by parasitic elements 27 / 31 www.rohm.com ? 2013 rohm co., ltd. all rights reserved. tsz22111 ? 15 ? 001 tsz02201 - 0e3e0h300240 -1-2 21.aug.2014 rev.003 downloaded from: http:///
