PT5616/PT5616A 3-Phase 600V 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 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 FEATURES Drives up to six IGBT/MOSFET power devices All high side channels fully operate up to +600V Gate drive supplies up to 18 V per channel Under-voltage lockout for all channels Over-current protection Flexible over-temperature shutdown input Advanced input filter Built-in dead-time protection Shoot-through (cross-conduction) protection Independent Enable/disable input and fault reporting Shutdown all switches during error conditions Adjustable fault clear timing Separate logic and power grounds 3.3 V/5V input logic compatible Designed for use with bootstrap power supplies Matched propagation delays for all channels Matched dead time -40°C to 125°C operating range SOP28 Package available Lead-free
