PT5607
600V Half-bridge driver IC
DESCRIPTION
The PT5607 is a high speed high voltage (600V) driver
to control power devices like MOS-transistors or
IGBTs in half bridge systems with dependent high and
low side referenced output channels. The logic input is
compatible with standard CMOS or LSTTL output,
down to 3.3V logic. The device includes an under-
voltage detection unit with hysteresis characteristic
and prevents power devices against large amount of
conduction loss, when voltage margin of gate is not
high enough. The output drivers feature a high pulse
current buffer stage designed for minimum driver
cross-conduction. The floating channel can be used to
drive an N-channel power MOSFET or IGBT, in the
high side configuration which operates up to 600 volts.
It is pin and input polarity compatible to IR2101.

FUNCTION DESCRIPTION
LOW SIDE POWER SUPPLY
VCC is the low side supply and it provides power both to input logic and to low side output power stage. The built-in
under-voltage lockout circuit enables the device to operate at sufficient power on when a typical VCC supply voltage
higher than
V
CCUV+
=8.6 is present, shown as Figure1. The IC shuts down the gate drivers outputs, when the VCC
supply voltage is below V
CCUV-
=8.1 V, shown as Figure1. This prevents the external power devices from extremely low
gate voltage levels during on-state and therefore from excessive power dissipation.

HIGH SIDE POWER SUPPLY
VB to VS is the high side supply voltage. The totally high side circuitry can float with respect to COM following the
external high side power device emitter/source voltage. Due to the internally low power consumption, the whole high
side circuitry can be supplied by bootstrap topology connected to VCC, and it can be powered with small bootstrap
capacitor tied between PIN VB and PIN VS.
The device operating area as a function of the supply voltage is given in Figure2.
