PT5616A 3-Phase 600V Gate Driver IC DESCRIPTION FEATURES 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 compatible 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 200mA for pull-up and 400mA 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.

This pin has negative logic and an open-drain output. The use of over-current and over-temperature protection requires the use of external components. Analog input for over-current shutdown. When active, ITRIP shuts down outputs and activates 7 ___________ ___________ FAULT and RCIN low. When ITRIP becomes inactive, FAULT stays active low for an externally set time tFLTCLR, then automatically becomes inactive (open-drain high impedance). Logic input to shutdown functionality. Logic functions when EN is high (i.e., positive logic). No ___________ effect on FAULT and not latched. EN can also be extended as input of over-temperature protection when equipped with an external NTC resistor. An external RC network input used to define the FAULT CLEAR delay (t FLTCLR) approximately ___________ equal to R*C. When RCIN > 8 V, the FAULT pin goes back into an open-drain high-impedance state.
