Chapter 5. Evaluation Board Demonstration
5.1 INTRODUCTION
This chapter provides insight to the PAC17X0 High-Side Current Sensors Evaluation
Board capabilities.
5.2 STEADY-STATE CURRENT SOURCE – ROTARY SWITCH 1
Rotary Switch 1 provides a means to control the current level through the on-board
1

sense resistor in fifteen discrete steps (see Section 3.6.1 “Steady-State Current
Source” ). To demonstrate this, complete the following steps:
1. In the Chip Manager application, select Bus Monitoring from the left pane to show
registers. Right-click a V
SENSE
range and add it to the registers to plot (see
Figure 5-1 and Section 4.1.2 “Selecting Registers to Plot” ).
FIGURE 5-1: Selecting Register to Plot.
2. Turn all rotary switches to the “0” position.
3. Go to the Control menu and start the plot.
Figure 5-2 shows a plot of current with
all switches off.
