現(xiàn)貨供應(yīng) PT5616 普誠 三相600V柵極驅(qū)動器IC

DESCRIPTION

The devices are full bridge drivers to control powerdevices like MOS-transistors or IGBTs in 3-phasesystems with a maximum blocking voltage of +600 V.The six independent drivers are controlled at thelow-side using CMOS and LSTTL compatible signals,down to 3.3V logic. The device includes an under-voltage detection unit with hysteresis characteristicand over -current detection. The over -current level isadjusted by choosing the resistor value and thethreshold level at pin ITRIP. Both error conditions(under-voltage and over-current) lead to a definite shutdown of all six switches. An error signal is provided atthe FAULT open drain output pin. The blocking timeafter over -current can be adjusted with an RC-networkat pin RCIN. Therefore, the resistor RRCIN is optional.The typical output current can be given with 200mA forpull-up and 400mA for pull down. Because of systemsafety reasons a 0.29us dead time has been realized.The function of inputs EN and ITRIP can optionally beextended with over-temperature detection, using anexternal NTC resistor, diodes and resistor network.
