(a dead time is needed to prevent sh ort circuits due to switching delay.) ? the level of the overcurrent protection current can be changed by using the external resistor r sd inserted between the i sd and v ss terminals. (it is necessary to connect resistor r sd to assure normal operation of overcurrent protection function. i sd is 28a to 38a when r sd is 0 .) ? the substrate temperature can be monitored through the use of an internal thermistor. ? transfer full mold structure sip.

STK621-043A-E no. a1339-3/8 notes 1. the on input signal voltage prescribes the input signal voltage at which the output stage igbt turns on, and the off input signal voltage prescribes the input signal voltage at which the output stage igbt turns off. apply a voltage between 0 and v ih (max) when output is on, and a voltage between v il (min) and v dd when output is off. 2. when the internal protection circuit is activated, the fault signal turns on (when the fault terminal is low level, fault signal is on state: output form is open drain) but the fault signal is not latched. after protection operation ends, the ic returns automatically within about 18ms to 80ms and establishes the state to start operation. so, after detecting the fault si gnal, set all input signals off (high) at once. the operation of under-voltage protection of the control power supply (uvlo: having a hysteresis of about 0.3v) is as follows. upper arm outputs no fault signal, but turns off the corres ponding gate signal. it returns to the regular operation after recovering the normal voltage, but the latch state continues while the input signal is on (low). lower arm outputs fault signal while turns the gate signal off. however, unlike the protection operation of upper arm, it returns automatically within about 18ms to 80ms and establishes the state to start operation after recovering the normal voltage. (the protection operation is not latched by the input signal.) 3. when assembling the hybrid ic on the heat sink, tightening torque range is 0.8n ? m to 1.0n ? m. 4. the control supply voltage-drop protection function protects the devices when the control supply voltage drops due to some abnormality during operation. control supply voltage drop at the start of operation and other cases should be confirmed in the set-mounted condition. package dimensions unit:mm (typ) 123 56.0 22 2.0=44.0 2.0 46.2 11.4 0.5 2.5 5.0 3.4 0.6 6.2 3.2 0.5 25.8 62.0 50.0 (4.27) 5.5 2.0 2.0

(when not using the bootstrap method, each upper-side control power supply should be externally supplied by an independent power supply.) in addition, the upper-side supply voltage may be insufficient depending on how the power supply is controlled, so this should be checked. 2. fluctuating spike voltage may be generated during switching operation due to the effects of the floating inductance of the + and - pin power supply external wiring or other factor s. therefore, use a short wiri ng length (between ci and each pin) to reduce the wiring inductance, and take measures to suppress surge voltage such as connecting a snubber circuit (capacitor: cs, approximately 0.1 to 10f) for abso rbing voltage surges as close as possible between the + and - pins. 3. the fault terminal (pin19) is an open drai n type output (fault operation when it is low). the STK621-043A-E has a built-in thermistor between the fault and v ss terminals. it allows monitoring the substrate temperature using the divided voltage developed with the pull-up resistor rp. the resistance of the rp must be 10k or higher at a pull-up voltage vp of 5v and 39k or higher at a pull-up voltage vp of 15v. 4. i so terminal (pin 20) is for the electric current monitor. the external impedance must be 5.6k or higher. never connect between i so and v ss terminals. short-circuiting them may cause an excess current flow into the line and a hazardous situation may result. 5. a 5v (5.0 to 5.4v) zener diode is connected inside the signal input pins. when inputting voltage in excess of 5v, connect a resistor between the power supply side and the signa l input pin so that the input current to the signal input pin is 0.5ma or less. this resistor is also effective for absorbing noise. 6. the overcurrent protection function is valid only when circuit control can be performed normally. be sure to provide a fuse in the v cc line or otherwise ensure safety in the set design. 7. the ic may become damaged or rupture if the motor connection pins (pins 2, 5 and 8) are open during motor rotation. take special care for the connections (soldered condition) of these pins. 8. the overcurrent protection feature operates normally wh en an external resistor r sd is connected between the i sd and v ss terminals. be sure to connect this resistor (or sh ort-circuit ) between them. the level of the overcurrent protection current can be lowered by using the external resistor r sd . 9. if the - terminal and the v ss terminal are short-circuited externally , since an overcurrent protection value (i sd ) may fall below the value set inside the hic due to adverse effect of wiring, it is required to check the condition with the actual unit when designing. (?terminal and v ss terminal are connected inside hic)
