the block diagram of this board.
FIGURE 1-1: PAC17X0 High-Side Current Sensors Evaluation Board Block Diagram.
The evaluation system is comprised of the PAC17X0 High-Side Current Sensors
Evaluation Board and the Microchip Chip Manager application. The PAC17X0
High-Side Current Sensors Evaluation Board has the following features:
• Test points and LEDs for monitoring on-board function
• Screw terminal connections for monitoring external system current up to 20A
• Multiple on-board adjustable current sources (steady state, square wave,
test pulse)
• USB-to-SMBus bridge for power and communications
• Capability to connect directly to external SMBus master
The user can perform the following operations using the Chip Manager application:
• Viewing and changing register values
• Saving settings of all registers, allowing for quick configuration at a later time
• Graphing of any register
