PT5617
High Voltage 3-Phase Gate Driver
DESCRIPTION
The PT5617 is a high speed power MOSFET and IGBT
driver with three independent high and low side
referenced output channels for 3-phase gate driver.
Built-in deadtime protection and Shoot-through protection
that prevent half-bridge breakdown. The UVLO circuits
prevent malfunction when VCC and VBS are lower than
the specified threshold voltage. 600V high-voltage
process and common-mode noise canceling technique
provide stable operation of high-side drivers under
high-dv/dt noise circumstances.

FUNCTION DESCRIPTION
LOW SIDE POWER SUPPLY (VCC, GND
（
SGND, PGND
）
)
VCC is the low side supply and it provides power to both input logic and low side output power stage. In PT5617-S2, input
logic is referenced to SGND as well as the under-voltage detection circuit. Output power stage is referenced to PGND.
PGND ground is floating respect to SGND ground with a recommended range of operation of +/-5V, which guarantees
enough margin of gate to source voltage, V
GS
, to driver power devices such as power MOSFET.
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+
=9.5 is present, shown as FIG1. The IC shuts down all the gate drivers outputs, when the VCC
supply voltage is below V
CCUV-
=8.8 V, shown as FIG1. 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 (VBU-VSU, VBV-VSV, VBW-VSW)
VB to VS is the high side supply voltage. The totally high side circuitry can float with respect to SGND 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 capacitors.
The device operating area as a function of the supply voltage is given in Figure2.
