Functional Description
This board has been developed to experience the features of the innovative isolated 8 channel high side driver
ISO2H823V2.5
. The following sub chapters will explain the features and setup possibilities of the evaluation board
and the
ISO2H823V2.5
.
The boards provided by Infineon have been subjected to functional testing only.
Due to their purpose, evaluation boards are not subjected to the same procedures regarding Returned Material
Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products. The
boards are intended for development support only and should not be used directly as reference designs for volume
production.
See Legal Disclaimer and Warnings for further restrictions on Infineon’s warranty and liability.
2.1
Power Supply
The Evaluation board can be powered on the connector X1 or via the connector SV1 with 3.3V. The process side
can be powered via the 2 pin terminal X2 with 24V nominal.
2.2
Microcontroller Interface
The
ISO2H823V2.5
contains a microcontroller interface, which can be configured as a parallel or serial interface
via the SEL pin.
SEL (Serial or Parallel Mode Select)
When this pin is in a logic Low state, the IC operates in parallel mode. For serial mode operation the pin has to be
pulled into logic High state. This pin has an internal Pull-Down resistor.
CS (Chip Select)
When this pin is in a logic Low state, the IC interface is enabled and data can be transferred. This pin has an
internal Pull-Up resistor.
