input section l6377 8/16 4 input section an input and asynchronous reset, both ttl/cmos compatib le with wide voltage range and high noise immunity (thanks to a built in hysteresis) are available. 5 over temperature protection (ovt) an on-chip over temperature protection provides an excellent protection of the device in extreme conditions. whenever the temperature - measured on a central portion of the chip- exceeds t max =150 c (typical value) the device is shut off, and the diag output goes low. normal operation is resumed as the chip temperature (normally after few seconds) falls below t max -t hys = 130 c (typical value). the hysteresis avoid thats an intermittent behaviour take place. 6 under voltage protection (uv) the supply voltage is expected to range from 8 to 35 v. in this range the device operates correctly. below 8v the overall system has to be considered not reliable. to avoid any misfunctioning the supply voltage is continuously monitored to provide an under voltage protection. as v s falls below v sth -v shys (typically 7.5 v, see fig. 4) the output power mos is switched off and diag output goes low. normal operation is resumed as soon as v s exceeds v sth . the hysteretic behaviour prevents intermittent operation at low supply voltage.
l6377 over current operation 9/16 7 over current operation in order to implement a short circuit protection the output power mos is driven in linear mode to limit the output current to the isc value. this i sc limit is externally settable by means of an external 1/4 w resistor connected from r sc pin and gnd. the value of the resistor must be chosen according to the following formula: i sc (a) = 5/r sc (k ? ) with 5 < r sc < 30 (k ? ) for r sc < 5 (k ? ) i sc is limited to i sc = 1.1 a (typical value). this condition (current limited to the isc value) lasts for a ton time interval, that can be set by means of a capacitor (c don ) connected to the on delay pin according to the following formula: t on = 1.28 s/pf for 50 pf < c don < 2 nf after the t on interval has expired the output power mos is switched off for the t off time interval with: t off = 64*t on . figure 5. short circuit operation waveforms output current t on t on t off t off time t over current operation l6377 10/16 when also the t off interval has expired, the output power mos is switched on. now two conditions may occur the overload is still present. in this case the output power mos is again driven in linear mode (limiting the output current to i sc ) for another t on , starting a new cycle, or the overload condition is removed, and the output power mos is no longer driven in linear mode. all these occurrences are presented on the diag pin (see fig 5). we call this unique feature non dissipative short circuit protection and it ensures a very safe operation even in permanent overload conditions. note that, of course, choosing the most appropriate value for the t on interval (i.e. the value of the c don capacitor) a delay (the t on itself) will prevent that a misleading short circuit information is presented on the diag output, when driving capacitive loads (that acts like short circuit in the very beginning) or incandescent lamp (a cold filament has a very low resistive value). the non dissipative short circuit protection can be disabled (keeping t on = 0 but with the output current still limited to is c, and diagnostic disabled) simply shorting to ground the the on delay pin.
l6377 demagnetisation of inductive loads 11/16 8 demagnetisation of inductive loads the l6377 has an internal clamping zener diode able to demagnetise inductive loads. note that the limitation comes from the peak power that the package can handle. attention must be paid to a proper thermal design of the board. if, for whatever reason (load current or inductive value too big) the peak power dissipation is too high, an external zener plus diode arrangement, can perform a demagnetisation versus ground or versus v s (see fig 5 and 6). the breakdown voltage of the external zener diode must be chosen considering the internal clamping voltage (v cl ) and the supply voltage (v s ) according to: v z < v cl(min) -v s(max) for demagnetisation versus ground or v s(max) demagnetisation of inductive loads l6377 12/16 figure 8. external demagnetisation circuit (versus ) driver v s ovc out r s short circuit control uv current limit d94in111a v z v s ( max ) < v z < v cl ( min ) v s
