STK611-721-E no.a1718-3/9 notes 1. << input on threshold voltage >> indicates the threshold of input signal to turn on output stage mosfet. << input off threshold voltage >> indicates the threshold of input signal to turn off output stage mosfet. at the time of output on, set the input signal voltage to vinth (on)max to 15v. at the time of output off, set the input signal voltage to 0v to vinth (off)min. 2. when the internal protection circuit operates, a ?fau lt/en? signal is turned on (when the ?fault/en? terminal is low level, ?fault/en? signal is on state: output fo rm is open drain) but the ?fault/en? signal does not latch. after protection operation ends, it returns automatic ally within typ. 8ms and resumes operation beginning condition. so,after ?fault/en? signal detecti on, set all signals to off (low) at once. however, the operation of pre-drive power supply low vol tage protection (uvlo with hysteresis about 0.2v) is as follows: upper side : there is no ?fault/en? signal output, but a corresponding gate signal is turned off. incidentally, it returns to the regular operation when recovering to the normal voltage, but the latch continues while the input signal is on (high). lower side : it outputs ?fault/en? signal with gate signal off. however, it is different from the protection operation of upper side, it is automatically reset and resumes operation beginning condition when recovering to normal voltage. (the protection operation is not latched by the input signal.) 3. when assembling the h-ic on the heat sink, tightening torque range is 0.4n?m to 0.6?nm. 4. the pre-drive low voltage protection is the function to protect devices when the pre-drive supply voltage declines with an operating malfunction. as for the pre-driver supply voltage decline in case of operation beginning, and so on, check it in your set. 5. please seal the entire leads of h-ic with the resin for securing the insulation between leads after mounting h-ic on the set. package dimensions unit:mm (typ) 29.2 25.6 (20.47) (5.0) (12.9) (5.6) 18 x1.0=18.0 1.0 4.2 8.2 (20.4) 0.5 0.4 4.5 119 14.5 7.2 14.4 11.0 (5.0) (r1.7) (3.5) 2.0

STK611-721-E no.a1718-8/9 usage precaution 1. by the addition of the diode for the bootstrap (db : high speed type with withstand voltage of 600v or more) and of the capacitor (cb : about 1 to 47 f), a single power supply drive is enabled. in this case, an electric charge is charged to cb by turning on the lower side igbt (by inpu tting low signal to lower side). the problem of causing the adverse effect by the noise etc. might occur because bi g charging current flows when the voltage of cb is low as started, and put limitation resistor rb (about tens of from the number of ), please. (when not using bootstrap circuit, each upper side pre-driver needs an external independent power supply.) also, the upper side power supply voltage sometimes declines depending on controlling condi tion. please confirm the voltage with an actual set. 2. the voltage jump associated with vibration caused by the switching operation occurs through the influence of floating inductance on the wiring of the ex ternal power supply, which is connected to ?+? and ?-? terminals; therefore, it is recommended that the wiring induct ance be low by shortening the wiring length (between ci and each terminal) and the snubber circuit (capacitor/cs/about 0.1 to 10 f) for voltage absorption be connected as close as possible between ?+? and ?-? terminals to reduce the surge voltage. 3. output form of ?fault/en? terminal (pin 17) is open drain (it operates as ?fault? when becoming ?low?). moreover, please connect the pull-up resistor (rp) so that the voltage of this terminal may usually become 2.5v or more because this terminal holds the sh utdown input of internal pr e-driver (it usually operates by 2.5v or more, and stop operation by 0.8v or less) concurrently. when the pull-up voltage is 5v, use rp with resistance 6.8k or more, and in case of 15v, use rp with resistance 20k or more. 4. inside the h-ic, a thermistor is connect ed between ?th? terminal (pin 1) and ?v ss ? terminal (pin 19). the thermistor can be used as the temperature monitor by connecting the pull-up resistor (rp) externally. when the pull- up voltage is 5v, use ?rp? with resistance 10k or more, and in case of 15v, use ?rp? with resistance 39k or more. 5. although the pull-down resistor is connected with the inside of the signal input terminal, connect the pull-down resistor (about 2.2 to 3.3k ) outside to decrease the influen ce of the noise by wiring etc. 6. the h-ic may be destroyed when the motor connection terminals (pins 4, 6 and 8) are opened while the motor is running; therefore please be especially careful about th e connection (soldering condition) of these terminals. 7. the ?itrip? terminal (pin 16) is the input terminal of the built-in comparator. it can stop operation by inputting the voltage more than vitrip (0.41v to 0.52v). (apply voltage less than vitrip to this pin when normal operation). please use it as various protections such as the overcurr ent protection (feedback from external shunt resistor). in addition, the protection operation will not be latched. after the protection operation ends, the h-ic operation resume s typ.8ms later. therefore, turn all the input signals off (low) as soon as the protection operation is detected. 8. when input pulse width is less than 1 s, an output may not react to the pul se. (both on signal and off signal) this data shows the example of the application circuit and does not guarantee a design as the mass production set.
