l9339 6/9 functional description the l9339 is a quad low side driver for lines, lamps or inductive loads in automotive and industrial applications. the logic input levels are ttl and cmos compatible. this allows the device to be driven directly by a micro- controller. for the noise immunity, all input thresholds has a hysteresis of typ. 100mv. at each input (in and prg) voltages from -0.3v to 32v can be applied, en can withstand voltages from -25v to 32v. the device is activated with a 'high' signal on enable. enable 'low' switches the device into the sleep mode. in this mode the quiescent current is less than 10a. a high signal on programming input changes the signal transfer polarity from noninverting into the inverting mode. this pin can be connected to v s or gnd. the forced status of the prg and en pin is low, if these pins are not connected. this forced condition leads to a mode change if the prg pin was high before the interruption. independent of the programming input, the output switches off, if the signal input pin is not connected. each output driver has a current limitation of min 0.4a and a independent thermal shut-down. the thermal shut- down deactivates that output, which exceeds temperature switch off level. when the junction temperature de- creases 20k below this temperature threshold the output will be activated again (hysteresis of the thermal shut- down function). the slew rate of the output voltage is limited to max. 14v/s, to reduce the electromagnetic radiation of the loads and its wiring. for inductive loads a output voltage clamp of typicaly 52v is implemented. the diagnostic is an open drain output with an additional series diode. the logic status depends on the pro- gramming pin. if the prg pin is 'low' the diag output becomes low, if the device works correctly. at thermal shut-down of one channel the diagnostic output becomes high. if the prg pin is 'high' this output is switched off at normal function and switched on at overtemperature. diagnostic table x = not relevant * selective for each channel at overtemperature pins en prg in out diag correct function h l l l (on) l (on) h l h h (off) l (on) h h l h (off) h (off) h h h l (on) h (off) l x x h (off) h (off) overtemperature or supply voltage h l x h (off) * h (off) overtemperature h h x h(off) * l(on)
