STEVAL-IHT003V2
Low loss e-starter evaluation board for compressor starter
circuits based on the ACST6
Data brief
Features
 Suitable for refrigerator and freezer
compressor applications
 Reduces PTC resistor power losses
 RoHS compliant
Description
The STEVAL-IHT003V2 evaluation board
represents an innovative solution patented by
STMicroelectronics to reduce the power losses
caused by positive temperature coefficient (PTC)
resistors in compressor starter circuits.
The solution features an ACST6 AC switch
device to turn off the PTC current after motor
start-up; note that the traditional PTC is still used
in the electronic starter circuit as it increases
circuit safety for AC switch short-circuits or diode
mode failure (ref. EN60335-1).
The design reduces starter standby losses from
(typ.) 2.5 W to 380 mW for 230 V applications, or
2.5 W to 40 mW for 100 V applications.
Before using the board with a compressor, the
PTC behavior must be checked (especially
VPTC1 and VPTC2 levels) and different R4
resistor values may be required.
