PT5616 Datasheet | PTC

DESCRIPTION The devices are full bridge drivers to control power devices like MOS-transistors or IGBTs in 3-phase systems with a maximum blocking voltage of +600 V. The six independent drivers are controlled at the low-side using CMOS and LSTTL patible signals, down to 3.3V logic. The device includes an under -voltage detection unit with hysteresis characteristic and over -current detection. The over -current level is adjusted by choosing the resistor value and the threshold level at pin ITRIP. Both error conditions (under-voltage and over-current) lead to a definite shut down of all six switches. An error signal is provided at the FAULT open drain output pin. The blocking time after over -current can be adjusted with an RC-network at pin RCIN. Therefore, the resistor RRCIN is optional. The typical output current can be given with 200m A for pull-up and 400m A for pull down. Because of system safety reasons a 0.29us dead time has been realized. The function of inputs EN and ITRIP can optionally be extended with over-temperature detection, using an external NTC resistor, diodes and resistor network.
