一、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. 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。
