14 Power sages 5 Power sages The hree oupu sages are realized as high-side curren sources wih an oupu curren up o 80mA. During off sae he leakage curren a he oupu sages is minimized in order o preven a slighly glowing LED. The maximum oupu curren is limied by he power dissipaion and used PCB cooling areas. For an operaing oupu curren conrol loop, he supply and oupu volages have o be considered according o he following parameers: Required supply volage for curren conrol V S(CC) Volage drop over hrough he oupu sage during curren conrol V PSx(CC) Required oupu volage for curren conrol V OUTx(CC) 5.1 Proecion The device provides embedded proecive funcions, which are designed o preven IC damage under faul condiions described in his daashee. Faul condiions are considered as ouside normal operaing range. Proecive funcions are no designed for coninuous nor for repeiive operaions Thermal proecion A hermal proecion circuiry is inegraed in he device. I is realized by a emperaure monioring of he oupu sages. As soon as he juncion emperaure exceeds he curren reducion emperaure hreshold T J(CRT) he oupu curren can be reduced by he device by reducing he IN_SETx reference volage V IN_SETx(ref). This feaure grealy helps o avoid LEDs flickering during saic oupu overload condiions. Furhermore, i helps o proec he LEDs, which are mouned hermally close o he device, agains overemperaure. If he device emperaure sill increases, he hree oupu currens decrease close o 0 A. As soon as he device cools down he oupu currens rise again.

The dimensioning of he resisors can be done using he formula: I = k I = k V / R OUTx IN _ SETx IN _ SETx( ref ) SETx (5.1) The gain facor k x (defined as he raio I OUTx /I IN_SETx ) is graphically described in Figure 7. The curren hrough he R SETx is defined by he resisor iself and he reference volage V IN_SETx(ref), which is applied o he IN_SETx pin when he device is supplied and he channel enabled.

This signal can be used o urn off he relaive oupu sages of he IC. A minimum IN_SETx curren of I IN_SETx(ACT) is required o urn on he oupu sages.

This is possible wih he usage of an exernal pull-up resisor, allowing muliple devices o share he open drain diagnosis oupu pin ERRN.

Therefore an acive low sae can be deeced a ERRN pin when V ERRN < V ERRN(faul) and if his condiion is reached, provided he proper seup of he delay pin D, all he channels are swiched off. Similarly, when he faul is removed, ERRN pin is pu back in high impedance sae, and he channels reacivaion procedure can be compleed once D-pin volage is below he value V D(h), as illusraed in he iming diagrams in his chaper.

The D-pin is designed for 2 main purposes: To reac o error condiions in LED arrays according o he implemened faul managemen policy, in sysems where muliple LED chains are used for a given ligh funcion. To exend he channels deacivaion delay ime of a value D, adding a small signal capacior from he D- pin o GND. In his way, an unsable or noisy faul condiion may be prevened from swiching off all he channels of a given ligh funcion (i.e. driven by several driver ICs sharing he same error nework). The funcionaliy of he D-pin is shown in he Figure 14 simplified block diagram: If one LED wihin one chain fails in open load condiion or one of he device oupus are shored o GND, he respecive LED chain is off. Differen auomoive applicaions require a complee deacivaion of a ligh funcion, if he desired brighness of he funcion (LED array) can no be achieved due o an inernal error condiion. In normal operaive saus (no faul) a pull-down curren I D(PD) is sunk from he D-pin o GND. If here is a faul condiion (for, a leas, a filer ime faul ) in one of he LED channels driven by he IC or in any of he devices sharing he same ERRN error nework line, a pull-up curren I D(faul) is insead sourced from he D-pin. As a consequence, if a capaciive or open load is applied a his pin, is volage sars rising. When V D(h) is reached a D-pin, all he channels driven by he device are swiched off and if oher devices share he same ERRN and D-pins nodes, all he devices urn heir oupus off. Alernaively, if he D-pin is ied o GND, only he channel ha has been deeced wih a faul is safely deacivaed. Daashee 25 Rev. 1.00

Open load (OL) and OUTx shored o GND (SC) diagnosis feaures are also inegraed in he TLD2331-3EP. An open load condiion is deeced if he volage drop over one of he oupu sages V PSx is below he hreshold V PSx(OL) a leas for a filer ime faul. A shor o GND condiion is deeced if he volage of one oupu sages V OUTx is below he hreshold V OUTx(SC) a leas for a filer ime faul Faul managemen (D-pin open or conneced wih a capacior o GND) Wih D-pin open or conneced wih a capacior o GND configuraion, i is possible o swich off all he channels which share a common error nework, wihou he need of an auxiliary microconroller. For more deails refer also o he iming diagram of Figure 15, Figure 16. If here is an OL or SC condiion on one of he oupus, a pull-up curren I OUT(faul) hen flows ou from he affeced channel, replacing he configured oupu curren (bu limied by he acual load impedance, e.g. reduced o zero wih an ideal open load). Under hese condiions, he ERRN pin sars sinking a curren I ERRN(faul) oward GND and (wih proper dimensioning of he exernal pull-up resisor) reaches a volage level below V ERRN(faul). Afer D(se), he volage V D(h) is reached a D-pin, he IN_SETx goes in a weak pull-down sae wih a curren consumpion I IN_SETx(faul) afer an addiional laency ime IN_SETx(del). The ERRN low volage can also be used as inpu signal for a microconroller o perform he desired diagnosis policy. The OL and SC error condiions are no lached: as soon as he faul condiion is no longer presen (a leas for a filer ime faul ) ERRN goes back o high impedance. When is volage is above V ERRN(faul), he D-pin volage sars decreasing and afer D(rese) goes below (V D(h) - V D(h,hys) ). Then he IN_SETx volages go up o V IN_SETx(ref), again afer a ime IN_SETx(del) : a his poin, he oupu sages are acivaed again. The oal ime beween he faul removal and he IN_SET reacivaion ERR(rese) is exended by an addiional laency which depends on he exernal ERRN pin pull-up and filer circuiry. Daashee 26 Rev. 1.00
