Figure 1. FRDM-24XSMBEVB and its shield board
The board can be used with different Kinetis MCU. This user guide is more dedicated on
FRDM-KL25Z board connected to a USB port of a PC and SPIGen software.
Configuration, control and statis monitoring the status of the power is accomplished by
using the SPI communication capabilities of the board. Control can be achieved through
the GPIO, configuring the direct input pins. Embedded LEDs witnesses the faults, mode
and output state.
4.2 Board features
The FRDM-24XSMBEVB is a tool to evaluate one of the NXP parts MC06XS4200,
MC10XS4200, MC20XS4200, MC22XS4200 or MC50XS4200. The board set (mother
board + expansion board) features:
•
One fully protected dual smart high side switch
•
5 V voltage regulator
•
One solder shunt per channel for freewheeling diode in case of high inductive loads
•
10 μF tank capacitor on supply terminal to help to maintain voltage during inrush
current
