Printed-Circuit Board
The ISO5500 is an isolated gate driver with several important features. The printed-circuit board (PCB)
has been designed to support this device and to allow the user to evaluate its basic operation and
features. The left side of the PCB contains the interface to the input, control, and status functions of the
integrated circuit (IC). The right side of the PCB has been designed to interface to an IGBT (or MOSFET).
No electrical connections exist between the right and left sides of the PCB.

Refer to the ISO5500EVM schematic and bill of materials to become familiar with the PCB components
and layout. The PCB files (Gerber/ODB) are available from Texas Instruments on request.

ISO5500 Operation
2.1.1
Left-Side Operation: DC Power, Control, and Status
2.1.1.1
DC Power
The left side of the ISO5500 (and therefore the PCB) can be operated using either a +3.3-V (±10%) or +5-
V (±10%) dc power supply. The small amount of dc current required (<20 mA) means that the device can
also be battery operated. The dc power supply must be connected to TP10 (+5 Vdc) and TP9 (+5-Vdc
return). Also, a user can solder wires directly to the PCB from the dc power supply by means of the plated
through-holes located next to the test points.

2.1.1.2
Control and Status
The interface to the device is via the JMP1 header. It contains the VIN+ and VIN– inputs, the device
RESET, and FAULT indicator output. The JMP1 header allows easy connections to test equipment using
standard clip leads or QuietZone™ connectors. Each of the four signals also has a test point for additional
connections. These are TP1 through TP4.
