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 **s, 
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 ** 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
