Thick-Film Hybrid IC
3-phase Inverter Motor Drive
STK621-140B-E
Inverter Hybrid IC
Overview
The STK621-140B-E is 3-phase inverter power hybrid IC containing power elements, pre-driver, and excessive
temperature protection circuit.
Applications
• 3-phase inverter motor drive.
Features
• Protective circuits including overcurrent (bus line), and pre-drive low voltage protection are built in.
• Direct input of CMOS level control signals without an insulating circuit is possible.
• The temperature monitor is enabled through the use of an internal thermistor.
• Single power supply drive is possible through the use of a built-in upper-side power-supply bootstrap circuit (capacitor is
externally connected).
• Built-in simultaneous upper/lower ON prevention circuit to prevent arm shorting through simultaneous ON input for the
upper and lower side transistors. (Dead time is required for preventing shorting due to switching delay.)
• SIP (The single in-line package) of the transfer full mold structure.

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 (max).
IH
At the time of output OFF, set the input signal voltage V (min) to 5V.
IL
2. When the internal protection circuit operates, 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 9ms and resumes operation beginning condition.
So, after FAULT signal detection, set 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 operation of upper side, it is automatically resets about 9ms
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, tightening torque range is 0.8N•m to 1.0N•m.
4. The pre-drive low voltage protection is the feature to protect a device when the 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.

Precautions
1. A control power supply can be driven with one power supply by attaching the capacitor CB (1 to 47μF) for a
bootstrap. In this case, a bottom element is made to charge.
(When not using bootstrap circuit, each upper side pre-drive power supply needs an independent power supply.
Externally set.)
Moreover, since top power supply voltage may be insufficient depending on the control method, Please carry out a
check with the system.
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 outer power supply which is connected with of the + terminal
and the – terminal, restrains and spares serge voltage being as the connection of the snubber circuit (Capacitor / CS /
about 0.1 to 10μF) for the voltage absorption with the neighborhood as possible between + and the - terminal, and so
on, with making a wiring length (among the terminals each from CI) short and making a wiring inductance small.
3. ISO terminal (22pin) is for the electric current monitor.
Note that the overcurrent protection circuit is disabled when the ISO terminal is shorted with the V terminal.
SS
4. Output form of the FAULT terminal is open DRAIN (it is operating as FAULT when becoming low).
When pulling up the pin with a resistor, connect the resistor with a resistance of 5.6kΩ or more.
5. Zener diode with 5V (5.0 to 5.4V) is connected with the inside of the signal input terminal. When inputting the
voltage which exceeds 5V, connect resistor to between 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 over current protection feature operates 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. A thermistor is connected between the VTH terminal (pin 13) and V terminal (pin 23) inside the IC. The substrate
SS
temperature can be monitored by connecting an external pull-up resistor (RP). Connect the resistor with a resistance
of 10kΩ or more when the pull-up voltage (VP) is 5V and 39kΩ or more when the VP is 15V.
8. 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.
