STK621-140B-E

Thick-Film Hybrid IC

3-phase Inverter Motor Drive

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.

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 VSS terminal.

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 VCC line.

7. A thermistor is connected between the VTH terminal (pin 13) and VSS terminal (pin 23) inside the IC. The substrate

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.

* This data shows the example of the application circuit, does not guarantee a design as the mass production set.
