3-phase Inverter Motor Drive
Inverter Hybrid IC
Overview
This IC is a 3-phase inverter power hybrid IC containing power elements (IGBT and FRD), pre-driver, as well as
protection circuit in one package.
Application
• 3-phase inverter motor drive
Features
• Integrates power elements (IGBT and FRD), pre-driver, and protective circuit.
• Protective circuits including overcurrent (bus line), pre-drive low voltage protection are built in.
• Direct input of CMOS level control signals without an insulating circuit (photocoupler, etc) is possible.
• 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 level of the overcurrent protection current is programmable with the external resistance RSD between the ISD and
VSS terminals. (It is necessary to connect RSD to ensure normal operation of the overcurrent protection function.
ISD = 21A to 28A when RSD = 0Ω)
• 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 VIH (MAX).
At the time of output OFF, set the input signal voltage VIL (MIN) to 5V.
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 to 80ms 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
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 M3 type screw, tightening torque range is 0.8N•m to 1.0N•m.
Flatness of the heat-sink should be lower than 0.15mm.
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.

*1. Pre-driver power supply (VD4 = 15±1.5V) must have the capacity of IO = 20mA (DC), 0.5A (Peak).
Usage Precaution
1. By the addition of the diode for the bootstrap (DB : high speed type of trr 100ns or less, withstand voltage equal to or
more than 600V) and of the capacitor (CB : about 1 to 47μF), a single power supply drive is enabled. In this case, it
makes a lower side IGBT ON (input signal of lower side makes LOW).
Then it charges in CB. Incidentally, in case of start-up and so, when the voltage of CB is low, the big charging
electric current flows and sometimes becomes the cause which exerts a bad influence of noise and so on. Put
limitation resistor RB (Several Ω to about tens of Ω).
(When not using the bootstrap circuit, each upper side pre-drive power supply needs an external independent power
supply.)
Also, the upper side power supply voltage sometimes declines by the way of controlling. Please confirm.
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 0.22 - 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 (20pin) is for the electric current monitor. When the pull up with the resistance,use above 5.6kΩ Be
careful, because the overcurrent protection does not operate when short-circuiting in the ISO terminal and the VSS
terminal.
4. Output form of the FAULT terminal is open DRAIN (it is operating as FAULT when becoming LOW).
When the pull up with the resistance, use above 5.6kΩ.
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 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 overcurrent 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. 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. The over current protection feature operates normally when an external resistor RSD is connected between the ISD
and Vss terminals. Be sure to connect this resistor. The Level of the overcurrent protection current is variable
according to the RSD value.Select an RSD resistor of an optimum value
while referring to the formula shown on a separate sheet and connect it between the ISD and VSS terminals.
9. If - terminal and VSS terminal are short-circuited, since an over-current protection (ISD) value will become lower
than the inside setting value of HIC, please do not connect externally.
(–terminal and VSS terminal are connected inside HIC)
