TB9068FG 2012-02-22 5 functional description (1) 5v regulator circuit a nd current limiter circuit the on-chip linear 5v regulator is designed to operate an external series pnp power transistor to grant thermal stability over a wide range of ca r battery voltages. the phas e compensation capacitor is placed between pin ?compc? and collector of the external pnp tr. a wide range of output currents can be realized by choosing an appropriate external pnp transistor. the maximum base current output is about 1 ma. the current is controlled vi a sense resistor between ?vs? and ?vcc1?. when voltage across the sense resistor exceed vlimit then the terminal ?vrego? is off and cut the current to keep the constant output voltage of 5v regulator. it keeps the output alive but limiting to the maximum allowed current trying to keep an external mcu alive even if there is a problem with over current. it is possible to disable the over current detection by connecting ?vs? and ?vcc1? directly. detected current: i = (vcc1-vlimit)/r vlimit: vcc1-0.4v~vcc1-0.15v caution ? make sure driver output ?vrego? is correctly connected to the base of external pnp. in case this terminal is for example connect ed to gnd the lsi can not work properly and in worst case may be destroyed. when the terminal base of this tr. is connec ted or shorted to vcc1, outside pnp tr. is off and output voltage of regulator is off. ? connecting pin ?vs? to vcc1,vcc2 or gnd will make damage the lsi. ? in case the pin ?compc? is shorted to vcc1, it will cause lsi damage. and when it is shorted to gnd the 5v regulat or cannot work properly. ? when pin ?vreg1?,?vreg2? are open, outsi de pnp tr. cannot be controlled properly and output voltage of pin ?vreg? can exceed 5v . and in worst case destroying the 5v logic. when power is supplied to lsi, pleas e double-check if the collector of outside pnp tr. is connected to pin ?vreg? properly. (2) reset circuit see the following timing charts) 1. 5v low voltage detection (power on reset) this function detects if output voltage of 5v regulat or has dropped below certain threshold level using the internal band gap as reference. for system stability a hysteresis voltage wa s set-up between the reset detection voltage (vrstl) and reset cancel ation voltage (vrsth). even when using an external voltage regulator it?s 5v output is controlled by comparing to the internal high quality band gap reference.
TB9068FG 2012-02-22 6 2. power on reset timer and watch dog timer (at internal osc 4mhz) output pin ?nrst? will output ?l? 25ms (typ) after power on or during watch dog timer released reset signal. and after reset is canceled, pi n ?nrst? outputs h which is thru internal pull up resistor (10k ? ). after power on reset (pin ?ws?=l) is canceled, system changes to watch dog timer mode and waits for an input signal from pin ?ck? for 50ms.(=twd typ.). if the signal from pin ?ck? did not occur duri ng twd, pin ?nrst? c hanges output to l for about 5ms (trst). 3. watch dog timer (at internal osc 4mhz) TB9068FG has a built-in watch dog timer (wdt ). this function can be enabled/disabled by pin ?ws?. ws = l: wdt enable ws = h: wdt disable (but power on reset work independently) when wdt is enabled (ws=l), it waits for an acti vity signal from the mcu at the input pin ?ck?. when this signal does not change during 50ms (typ.), pin ?nrst? outputs l for 5ms (typ.). after that wdt restarts to count the time. (pin ?nrst? circuit configuration and diagram) (wdt timing chart) (wdt enable: ws=l)
TB9068FG 2012-02-22 7 (wdt disable: ws=h) (3) 4mhz internal cr oscillator TB9068FG has a built-in 4mhz cr oscillator whic h is operated from the internal stable 5v voltage. this clock is used for all internal timing purposes. (4) diagnostic circuit (dg1,dg2) TB9068FG has the over current / over voltage / over temperature detection circuit with a diagnostic monitor output ?dg1? and ?dg2?. each failure detected can be noticed by output pins ?dg1? and ?dg2? change to h as follows. w hen respective condition has come to an end (return to normal), each output pin return to l (normal). pin ?dg1? pin ?dg2? detected abnormal l l normal h detect over current h detect over temperature or over voltage h h detect over current, over temperature or over voltage ? ? : no relation 1. over voltage detection (vcc1) when vcc1 is over 27v(typ.), motor drivers are stopped (off, hi-z) and pin ?dg2? outputs h. as soon as vcc1 drops under 27v(typ.) motor driver returns to normal output and pin ?dg2? outputs l. * the above is the case to detect only over voltage (dg1=l,dg2=h)
TB9068FG 2012-02-22 8 caution this over voltage detection is not to clamp battery voltage for TB9068FG. thus, the system should keep lower operation voltage than the max. rating spec. 2. over temperature detection when the junction temperature exceeds 150c(mi n.), the motor drivers are off (hi-z), lin driver is off (hi-z) and pin ?dg1? output is h. when the temperature of the chip drops under 140 c(min.), motor driver return to normal and pin ?dg2? outputs l. the above is the case to detect only over temperature (dg1=l,dg2=h) caution the absolute maximum temperature of TB9068FG is 150deg. this over temperature detection function does not intend to limit the chip temperature. thus, the above absolute maximum temperature never is over to use TB9068FG. if any of these rating would be exceeded during operation, the device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed. moreover, these operations with exceeded ratings may cause break down, damage and/or degradation to any other equipment. applications using the device should be designed such that each maximum rating will never be exceeded in any operating conditions. before using, creating and/or producing designs, refer to and comply with the precautions and conditions set forth in this documents. this over temp. detection is worded over the max. rating temperature and shipping test does not perform at the max. rating temp.
TB9068FG 2012-02-22 9 3. over current detection when motor driver current exceeds 1.5a (min.), the motor drivers are off (hi-z) and pin ?dg1? outputs h. over current detection is not reset even when current falls to uncritical value and pin ?dg1? remains at h-level. to reset the over current condition a low pulse at pin ?ena(nblake)? is needed. over current reset actually happens during rising edge of the reset pulse and motor drivers are turned on and pin ?dg1? returns to l. if however during reset pulse still over current (>+/-1.5a) is detected the over current will remain and not be reset. the above is the case to detect only over current (dg1=h,dg2=l) [caution] over current detection 1.5a (min.) is based on overall motor current: detected current = the output current of pin ?oa? + the output current of pin ?ob? + the output current of pin ?oc? [caution] in mode0, motor driver off(h i-z) by abnormal detection is higher priority than brake function by pi n?ena(nbrake)? or pin?ia(ccw/ cw1)? .
TB9068FG 2012-02-22 10 (5) mode selection for motor control TB9068FG has 2 modes for motor control which are selected by pin ?sel? as follows 1. mode0 (sel=l or open) (f or 3phase brushless motor 120deg. square wave operation with hall sensor) the sensor signals which is input at pins ?id(sa)?, ?ie(sb)? and ?if(sc)? are processed by the internal logic and corresponding motor control outputs are available at pins ?oa?, ?ob?, ?oc?. pwm (l-side) motor speed control is available by applying low frequency pwm at the input pin ?ic (pwm)?. ena(nbrake) ia(ccw/cw1) ib (ccw/cw2) ic (pwm) id (sa) ie (sb) mode 0 120 deg. square wave operation control logic hb hb hb lah lal lbh lbl lch lcl oa ob oc sel (low or open) if (sc) pwmi(open) sampling circuit /noise cancelation circuit diag control dg1 dg2 sampling circuit in mode0, pin ?ib?,?pwmi? need to be kept open the equivalent circuit of motor driver

TB9068FG 2012-02-22 13 the hall sensor signals are proc essed by the internal logic to detect the rotor position. internal noise canceler ignores sensor signals shorter than 2-3 s(typ. at osc 4mhz). this delay between the input of sensor and output of motor driver include driver transistor swtching delay. in mode0 which provide120deg. square wa ve operation does not set dead time to protect short current betw een pch and nch sumultaneous on. in normal sequence of 120deg. sqare wave operation,there is no direct switching of motor driver between h and l. only in case of motror driver on/off by input ?ena(nbrake)?,the hi-z status of motor driver for 1us is set. (changing rotatin direction by pin?ia(ccw/cw1)? and ?ib(ccw/cw2)? in mode 0 the motor rotation direction is controlled by the inputs ?ccw/cw1? and ?ccw/cw2? in mode0, as follows. pin ?ia ccw/cw1 ? pin ?ib ccw/cw2 ? operation l l brake (l-side on) h l ccw (reverse) l h cw forward h h free h/l-side off when the motor rotation direction is changed by the input ?ccw/cw1? and ?ccw/cw2?, firstly a braking operation (input ?ccw/cw1?=?ccw/cw2?= l) is required. at each edge of ?ccw/cw1? and ?ccw/cw2? motor driver outputs are off(hi-z) for 1us.(typ. at osc 4mhz). (s ee the follows ) if the input ?ena(nbrake)? is l when driver outputs return to normal by ?ia?=h or ?ib?=h, driver outputs wait until input ?ean(nbrake)? become h. (ccw/cw1=ccw/cw2=l: braking oa=ob=oc=l) (ccw/cw1=ccw/cw2=h: free oa=ob=oc=hi-z)
TB9068FG 2012-02-22 14 when ?ccw/cw1?=?ccw/cw2?=h, each motor driver outputs are off(hi-z). and after detecting ccw/cw1=l or ccw/cw2=l, each driver output the signal according to ccw/cw1 and ccw/cw2. (rotation change at ?ena(brake)=l) before motor rotation direction is c hanged, once being brake by pin?pwmi?=0 and ?ena(nbrake)?=0 is recommendation. when ?ena(nbrake)? is changed, motor driver is off(hi-z) during 1 s(at 4mhz)
TB9068FG 2012-02-22 15 2. mode1 (sel=1) (for 3phase brushless motor control by mcu) the motor driver output signal is controlled by outside mcu. when the pwm speed control is required, mcu needs to gener ate and output the motor control signals with pwm pattern. or independently input pwm signal from input terminal ?pwmi? in mode1, TB9068FG does not generate the dead time. theref ore, mcu needs to control that short circuit current thru the driver pch and nch can not happen(avoid simultaneous occurrence of ia=id=h, ib=ie=h,ic=if=h). each motor driver output oa,ob,oc has t he delay around 0.2 - 1. 0us against each input signal ia - if. high side cont. input low side cont. input output ia id oa ib ie ob ic if oc
