STK621-061-E no.a1032-3/8 notes 1. input on voltage indicates a value to turn on output stage igbt. input off voltage indicates a value to turn off output stage igbt. at the time of output on, set the input signal voltage 0v to v ih (max). at the time of output off, set the input signal voltage v il (min) to 5v. 2. when the internal protection circuit op erates, there is a fault signal on (when the fault terminal is low level, fault signal is on state : output form is open drain) but the fault signal doesn't latch. after protection operation ends, it returns automatically within about 18ms to 80ms and resumes operation beginning condition. so, after fault signal detection, se t off (high) to all input signals at once. however, the operation of pre-drive power supply low voltage protection (uvlo: it has a hysteresis about 0.3v) is as follows. upper side there is no fault signal output, but it does a corresponding gate signal off. incidentally, it returns to the regular operation when recovering to the normal voltage, but the latch continues among input signal on (low). lower side it outputs fault signal with gate signal off. however, it is different from the protection operatio n of upper side, it is automatically resets about 18ms to 80ms later and resumes operation beginning condition when recovering to normal voltage. (the protection operation doesn't latch by the input signal.) 3. when assembling the hybrid ic on the heat sink with m4 type screw, tightening torque range is 0.79n?m to 1.17n?m. flatness of the heat-sink should be lower than 0.25mm. 4. the pre-drive low voltage protection is the feature to protect a device when th e pre-driver supply voltage declines with the operating malfunction. as for the pre-driver supply voltage decline in case of operation beginning, and so on, we request confirmation in the set. package dimensions unit:mm (typ) 22 1 70.0 7.0 6.0 1.5 3.5 3.5 5.0 5.0 10.0 31.1 (10.5) 10.0 3.0 16.0 4.6 22.0 4.5 0.5 5.0 2.54 0.75 1.5 74.0 64.0 78.0 82.0 13.0 9.0 18.5 21 2.54=53.34 1.5 2.7

(when not using bootstrap circuit, each upper side pre-drive power supply needs an independent power supply. externally set.) also, the upper side power supply voltage sometimes declines by the way of controlling. confirm it. 2. because the jump voltage which is accompanied by the vibration in case of switching operation occurs by the influence of the floating inductance of the wiring of the oute r power supply which is connected with of the + terminal and the ?terminal, restrains and sp ares serge voltage being as the connection of the snubber circuit (capacitor/cs/about 0.1 - 10 f) for the voltage absorption with the neighborhood as possible between + and the - terminal, and so on, with making a wi ring length (among the terminals each fr om ci) short and making a wiring inductance small. 3. iso terminal (20pin) is for the el ectric current monitor. be careful, because the overcurrent protection does not operate when short-circuiting in the iso terminal and the v ss terminal. 4. output form of the fault terminal is open dr ain (it is operating as fa ult when becoming low). when the pull up with the resistance, use above 5.6k . 5. zener diode with 5v (5.0 - 5.4v) is connected with the inside of the signal input terminal.when inputting the voltage which exceeds 5v,connect resistor to betwee n the side of the power and the signal input terminal,for the input current of the signal input terminal become equal to or less than 0.5ma. this resistor is effective with the noise absorption of the signal terminal,too. 6. the overcurrent protection feature oper ates only when it is possible to do a circuit control normally. for the safety, put a fuse, and so on in the v cc line. 7. because the ic sometimes destroys and bursts when motor connection terminal (2pin, 5pin, 8pin) becomes open while the motor turns, especially, be careful of the connection ( the soldering condition ) of this terminal. 8. if - terminal and v ss terminal are short-circuited, since an over-c urrent protection (isd) value will become lower than the inside setting value of hic, please do not connect externally. (?terminal and v ss terminal are connected inside hic) this data shows the example of the ap plication circuit, does not guarantee a design as the mass production set.
