PT5616 3-Phase 600V Gate Drive 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. The input RCIN owns an internal current source of 2μA. 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 0.5us 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 FAULT and RCIN low. When ITRIP becomes inactive, FAULT stays active low for an 9 12 EN 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 10 13 RCIN over-temperature protection when equipped with an external NTC resistor. An external RC network input used to define the FAULT CLEAR delay (tFLTCLR) approximately equal to R*C. When RCIN > 8 V, the FAULT pin goes back into an 11 14 VSS COM LOW LOV LOU NC. NC.
