3-phase Inverter Motor Drive
STK621-738-E
Inverter Hybrid IC
Overview
The STK621-738-E is an inverter power hybrid IC for use in 3-phase fan-motor applications and contains power stage,
pre-driver, and protection circuits.
Applications
• 3-phase inverter motor drive for air conditioners, washing machines, etc.
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.(Hi Active).
• Single power supply drive is possible through the use of a built-in upper-side power-supply bootstrap circuit (Needs
external capacitors).
• 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.)
• The current level for overcurrent protection can be adjusted by connecting an external resistor R
between the I
SD
SD
and V terminals.
SS
• The built-in thermistor allows substrate temperature to be monitored.

Notes
1. Input ON voltage turns on output stage and input OFF voltage turns off output stage.
Apply voltage Vinth (max) to 15V to the V (ON) pin to turn output stage on, and apply voltage 0V to Vinth (min)
IN
to the V (OFF) pin to turn output stage off.
IN
*1 : ”Input threshold voltage hysteresis” indicates a reference value based on the design value of built-in pre-driver
IC.
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 18ms and resumes operation beginning
condition. So, after Fault signal detection, set OFF (Low) to all input signals at once.
However, the operation of pre-drive power supply low voltage protection (UVLO: it has a hysteresis about 0.2V) 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 (High).
Lower side → It outputs FAULT signal with gate signal OFF.
However, it is different from the protection operation of upper side, it automatically resets about 18ms
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.)
In addition, please carry out capacity of the capacitor for a bootstrap (external) to 47μF ( 20%). When 47μF ( 20%)
or more are connected, Please connect resistance (about 20Ω) also with 3-phase at series between each top power
supply terminal (VB1, 2, and 3) and the capacitor for a bootstrap. 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. 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.
4. A thermistor is connected between the TH terminal (pin 29) and V terminal (pin 26) 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.
5. ISO terminal (24 pin) is for the electric current monitor. Connect an external impedance with 5.6kΩ or more to this
pin. In addition, Not short-circuit this pin to the V pin, that leads to large current drain and is dangerous.
SS
6. The pull-down resistor (: 33kΩ (typ)) is connected with the inside of the signal input terminal, but please connect the
pull-down resistor (about 2.2 to 3.3kΩ) outside to decrease the influence of the noise by wiring etc.
7. 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.
8. Because the IC sometimes destroys and bursts when motor connection terminal (2pin, 6pin, 10pin) becomes open
while the motor turns, especially, be careful of the connection (the soldering condition) of this terminal.
9. Since the overcurrent protection function operates normally when an external resistor RSD is placed between the ISD
and V terminals, it must always be connected between the terminals (or the terminals must be short-circuited). The
SS
current level for overcurrent protection can be lowered by using the external resistor RSD of an appropriate value.
10. When input pulse width is less than 1μs, an output may not react to the pulse.
(Both ON signal and OFF signal)
