PT5616A
3-Phase 600V Gate Driver IC
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
R
RCIN
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.

Indicates over-current, over-temperature (ITRIP), or low-side under-voltage lockout has
occurred. 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.
