3-phase Inverter Power H-IC
for 3-phase Motor Drive
Overview
This “Inverter Power H-IC” includes the PFC, the output stage of a 3-phase inverter, pre-drive circuits, as well as
protection circuits in one package.
Function
 Protective terminals including for over current protection each of Inverter part and PFC part are built in.
 Protective circuits including pre-drive low voltage protection is built in.
 Direct input of CMOS level control signals without an insulating circuit (photo coupler, etc) is possible. (Active
High)
 Single power supply drive is possible by using a bootstrap circuit with a built-in IC.
 In Inverter part, 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 emitter line of each lower phase transistor is outputting to the external terminal (3 terminals). Therefore, by
connecting shunt resistor outside, it is possible to the control which detects 3-phase current.
Certification
 UL1557 (File Number: E339285)

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 Vin(on) Min. to 15V.
At the time of output OFF, set the input signal voltage 0V to Vin(off) Max.
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 2ms (typ.) 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 is automatically resets 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 0.8 to 1.0 N·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.

STK57FU391A-E
Usage Precautions
1.
This H-IC includes bootstrap diode and resistors. Therefore, by adding a capacitor “CB”, a high side drive voltage is
generated; each phase requires an individual bootstrap capacitor. The recommended value of CB is in the range of 1
to 47μF, however this value needs to be verified prior to production. If selecting the capacitance more than 47μF
(±20%), connect a resistor (about 20Ω) in series between each 3-phase upper side power supply terminals (VB1,2,3)
and each bootstrap capacitor.
When not using the bootstrap circuit, each upper side pre-drive power supply requires an external independent
power supply.
2.
It is essential that wirning length between terminals in the snubber circuit be kept as short as possible to reduce the
effect of surge voltages. Recommended value of “CS” is in the range of 0.1 to 10μF.
3.
The “FLTEN” terminal (pins 31) is open Drain (It is operating as “FAULT” when becoming Low).This terminal
serves as the shut down function of the built-in pre-driver. Please make pulling up outside so that “FLTEN” terminal
voltages become more than 3V. (When the terminal voltage is above 3V, normalcy works, and it is shut down when
it is equal to or less than 0.8V). Moreover, thermistor built in between FLTEN(pins 31) and VSS(pins 35), so the
substrate temperature can be monitored according to the voltage divided by the thermistor and the pull-up resistor.
When the pull up voltage (VP) is at 5V, pull up resistor (RP) connects above 10kΩ, and in case of VP=15V, RP
connects above 39kΩ. The substrate temperature detection by the thermistor is for the substrate temperature monitor
in the state of regular operation and not for protection of HIC over-temperature. Moreover, it is not the one to
momentary heating-up, and partial heating-up.
4.
The pull-down resistor is connected with the inside of the signal input terminal, however please connect the
pull-down resistor(about 2.2 to 3.3kΩ) outside to decrease the influence of the noise by wiring etc.
5.
The over-current protection feature operates only when it is possible to do a circuit control normally. For safety,
recommend installation a fuse, and so on in the “Vcc” line.
6.
Because the H-IC can be destroyed when the motor connection terminal (pin No.5, 9 and 13) is opened while the
motor is running, please be especially careful of the connection (soldering condition) of this terminal.
7.
The “ITRIP” terminal (33pin) and the “PFCTRIP” terminal (32pin) are the input terminal of the built-in comparator.
It can stop movement by inputting the voltage more than reference voltage. (At the time of movement, usually those
terminals give it for the voltage less than reference voltage). Please use it as various protections such as the
over-current protection (feedback from external shunt resistance). In addition, the protection movement is not done
a latch of. After the protection movement end, It becomes the movement return state after 2ms (typ.). So, please do
the protection movement detection of all input signals in OFF (LOW) promptly afterward.
8.
When input pulse width is less than 1.0us, an output may not react to the pulse. (Both ON signal and OFF signal)

Cb capacitor value calculation for boot-strap circuit (Cb)
Calculate conditions
Parameter
Upper side power supply.(VD)
Total gate charge of output power IGBT at 15V.(Qg)
Upper side power supply low voltage protection.(UVLO)
Upper side power dissipation.(Idmax)
Value
15[V]
0.132[μC]
12V
400[uA]
Capacitance calculation formula
Tonmax is upper arm maximum on time' equal the time when the Cb voltage falls from 15V to the upper limit of 'Low
voltage protection level.
“ton-maximum" of upper side is the time that Cb decreases 15V to the maximum low voltage protection of the upper side
(12V).
Thus, the following formula  is true.
VD x Cb – Qg – Idmax x tonmax = UVLO x Cb -------- *1
Cb = ( Qg + Idma x tonmax ) / ( VD – UVLO) --------- *2
The relationship between tonmax and Cb becomes as follows.
