IN1 and IN2 external inputs

The FRDM-HB2000ESEVM, with a FRDM-KL25Z board (shipped with the kit), can

evaluate the design with a GUI, any MCU with GPIO or with simple lab equipment. A

FRDM-KL25Z compatible GUI and MCU program are available online at the following

link: http://www.nxp.com/FRDM-HB2000ESEVM.

The FRDM-HB2000ESEVM is compatible with any Arduino platform board. However, if a

board other than the FRDM-KL25Z is used, MCU code must be written to work with the

board.

4.7 Input signal definitions

The following input signals control the outputs or functions inside the circuit.

Table 5. Input signal definitions

Input name

Description

DIS

disable signal to 3-state the outputs

ENBL

disable signal to 3-state the output and put the part in Sleep mode

IN1

logic input to control OUT1

IN2

logic input to control OUT2

MOSI

master output slave input for the SPI

CS_B

chip select bar input for the SPI

SCLK

clock for the SPI

4.8 Output signal definitions

The FRDM-HB2000ESEVM uses the following output signals to drive a load such as

a brushed DC motor. The board provides an analog output for real-time load current

monitoring. This signal allows closed-loop control of the load.
