HW Monitor 3 Click

‍HW Monitor 3 Click is a compact add-on board designed for precise voltage monitoring and supervision in critical systems. This board features the TPS389006, a six-channel window voltage supervisor IC from Texas Instruments, offering SIL-3 safety compliance. This board features I2C programmability, ±6mV accuracy, built-in CRC error checking, sequence logging, and an integrated ADC for real-time voltage readouts. It supports fixed window thresholds with fine granularity, undervoltage lockout (UVLO) at 2.48V, and remote sensing to monitor high-current rails accurately.

Software Support

We provide a library for the HW Monitor 3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

‍This library contains API for HW Monitor 3 Click driver.

Standard key functions :

Example key functions :

Example Description

‍This example demonstrates the use of HW Monitor 3 Click board by reading and displaying the voltage level from 6 analog input channels.

The demo application is composed of two sections :

Application Init

‍Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
hwmonitor3_cfg_t hwmonitor3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
hwmonitor3_cfg_setup( &hwmonitor3_cfg );
HWMONITOR3_MAP_MIKROBUS( hwmonitor3_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == hwmonitor3_init( &hwmonitor3, &hwmonitor3_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( HWMONITOR3_ERROR == hwmonitor3_default_cfg ( &hwmonitor3 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

‍Reads the voltage level from all 6 analog input channels and displays the results on the USB UART once per second approximately.

void application_task ( void )
{
if ( HWMONITOR3_OK == hwmonitor3_read_voltage ( &hwmonitor3, &ch_mon ) )
{
log_printf ( &logger, " CH1: %.3f V\r\n", ch_mon.ch1_v );
log_printf ( &logger, " CH2: %.3f V\r\n", ch_mon.ch2_v );
log_printf ( &logger, " CH3: %.3f V\r\n", ch_mon.ch3_v );
log_printf ( &logger, " CH4: %.3f V\r\n", ch_mon.ch4_v );
log_printf ( &logger, " CH5: %.3f V\r\n", ch_mon.ch5_v );
log_printf ( &logger, " CH6: %.3f V\r\n\n", ch_mon.ch6_v );
}
Delay_ms ( 1000 );
}

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.HWMonitor3

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
