1. Out of the Box

The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the RDGD3162CSL3PEVM board.

RDGD3162CSL3PEVM with KITGD316xTREVB attached as shown in Figure 1 using Windows-based PC and FlexGUI software.

Note: Double pulse and short-circuit testing can be conducted on phase U only.

Suggested equipment needed for test:

Rogowski coil high-current probe
High-voltage differential voltage probes
High sample rate digital oscilloscope with probes
DC link capacitor compatible with Bosch CSL B-sample power module
Bosch CSL B-sample SiC power module
Windows-based PC
High-voltage DC power supply for DC link vol
Low-voltage DC power supply for VPWR – +12 V DC gate drive board low-voltage domain
Voltmeter for monitoring high-voltage DC link supply
Load coil for double pulse testing (phase U only)

Note: To enable short-circuit testing on phase U only, two resistors (R100, R121) must be removed from PWMALT phase U signals to disable dead time control on phase U gate drivers.
