load and high ? load conditions. thermal protection internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. when activated at typically 175 c, the regulator turns off. this feature is provided to prevent failures from accidental overheating. maximum package power dissipation the power dissipation level is maximum allowed power dissipation for particular package or power dissipation at which the junction temperature reaches its maximum operating value, whichever is lower. applications information the NCV8768 regulator is self ? protected with internal thermal shutdown and internal current limit. typical characteristics are shown in figures 4 to 27. input decoupling (c in ) a ceramic or tantalum 0.1 f capacitor is recommended and should be connected close to the NCV8768 package. higher capacitance and lower esr will improve the overall line and load transient response. if extremely fast input voltage transients are expected then appropriate input filter must be used in order to decrease rising and/or falling edges below 50 v/ s for proper operation. the filter can be composed of several capacitors in parallel. output decoupling (c out ) the NCV8768 is a stable component and does not require a minimum equivalent series resistance (esr) for the output capacitor. stability region of esr versus output current is shown in figure 13. the minimum output decoupling value is 1.0 f and can be augmented to fulfill stringent load transient requirements. the regulator works with ceramic chip capacitors as well as tantalum devices. larger values improve noise rejection and load regulation transient response. enable operation the enable pin will turn the regulator on or off. the threshold limits are covered in the electrical characteristics table in this data sheet. reset operation a reset signal is provided on the reset output (ro) pin to provide feedback to the microprocessor of an out of regulation condition. the timing diagram of reset function is shown in figure 24. this is in the form of a logic signal on ro. output voltage conditions below the reset threshold cause ro to go low. the ro integrity is maintained down to v out = 1.0 v. the reset output (ro) circuitry includes www.datasheet.co.kr datasheet pdf - http://www..net/ NCV8768 http://onsemi.com 15 a pull ? up resistor (30 k ) internally connected to the output (v out ). no external pull ? up is necessary. window watchdog operation the watchdog slow, fast or off state is set by pins wm1 and wm2 (see table in figure 25). the timing values used in this description refer to typ. values when wm1 and wm2 are connected to gnd (fast watchdog and reset timing). the state diagram of the window watchdog (wwd) and the watchdog and reset mode selection table is shown in figure 25. the wwd timing is shown in figure 26. after power ? on, the reset output signal at the ro pin (microprocessor reset) is kept low for the reset delay time t rd (16 ms). ro signal transition from low to high triggers the ignore window (iw) with duration of t iw (32 ms). during this window the signal at the wdi pin is ignored. when iw ends a long open window with maximum duration of (128 ms, t max = 4xt ow ) is started. when a valid trigger signal is detected during long open window, a closed window (cw) with duration of t cw (32 ms) is initialized immediately. wdi signal transition from high to low is taken as a trigger. as valid trigger two high samples followed by two low samples (with sampling time t sam = 0.5 ms) have to be present before end of the long window. valid wdi trigger signal is shown in figure 27. when cw ends a standard open window (ow) with maximum duration of t ow (32 ms) is initiated immediately. the ow ends immediately when valid trigger appears at wdi input. for normal operation the microprocessor timing of wdi pulses must be stable and correspond to t wd . a reset signal is generated (ro goes low) if there is no valid trigger (missing pulse at wdi pin) during ow or if a pre ? trigger occurs during the cw (unexpected pulse at wdi pin). thermal considerations as power in the NCV8768 increases, it might become necessary to provide some thermal relief. the maximum power dissipation supported by the device is dependent upon board design and layout. mounting pad configuration on the pcb, the board material, and the ambient temperature affect the rate of junction temperature rise for the part. when the NCV8768 has good thermal conductivity through the pcb, the junction temperature will be relatively low with high power applications. the maximum dissipation the NCV8768 can handle is given by: p d(max) t j(max) t a r ja (eq. 1) since t j is not recommended to exceed 150 c, then the NCV8768 soldered on 645 mm 2 , 1 oz copper area, fr4 can dissipate up to 1.3 w when the ambient temperature (t a ) is 25 c. see figure 28 for r ja versus pcb area. the power dissipated by the NCV8768 can be calculated from the following equations: p d v in i q @i out i out v in v out (eq. 2) or v in(max) p d(max) v out i out i out i q (eq. 3) figure 28. thermal resistance vs pcb copper area copper heat spreader area (mm 2 ) r ja , thermal resistance ( c/w) 80 90 100 110 120 0 100 200 300 600 400 500 700 pcb 2 oz cu soic ?
