Hardware Overview
How does it work?
IPD Click - 2015 is based on the TPD2015FN, an 8-channel high-side switch featuring MOSFET outputs from Toshiba Semiconductor, designed to be directly driven by CMOS and TTL logic circuitry. It's ideally suited for driving inductive and resistive loads, such as industrial programmable logic controllers for industrial use, motors, relays, lamps in factory automation equipment, and more. A key advantage of the TPD2015FN is its built-in overcurrent and overtemperature protection, enhancing system stability by safeguarding against excessive heat and current. Equipped with the capability to handle back electromotive force from inductive loads without surpassing the component's voltage tolerance, the TPD2015FN is optimized for loads up to 50mH with a current capacity of 0.5A per channel, supported by an external power supply ranging from 8-24V. The channels can be
operated in parallel to increase the current capability of the outputs. As mentioned, this Click board™ incorporates comprehensive protection mechanisms, including overtemperature protection that deactivates all outputs (OUT1-OUT8) if the temperature exceeds 175°C and overcurrent protection that limits voltage and current during load shorts, ensuring the device and its connected peripheral safety. Designed for straightforward integration with CMOS and TTL systems, the IPD Click features input control terminals for each output channel, allowing independent channel control. Inputs IN1 to IN4 interface directly via the mikroBUS™ socket, with additional inputs IN5 to IN8 accessible through an unpopulated header. Each input control pin of the TPD2015FN is equipped with a built-in 300kΩ pull-down resistor to maintain a LOW logic state in an open state. This
Click board™ comes with optional inductive load decoupling diodes unpopulated by default, the CRS20140A from Toshiba Semiconductor, allowing users to add them in the case of higher inductive loads. Also, it is equipped with jumpers for the diode configuration of the used load switch and its power management. These jumpers are pre-configured, enabling immediate use without the need for any adjustments. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Features overview
Development board
Nucleo 32 with STM32F031K6 MCU board provides an affordable and flexible platform for experimenting with STM32 microcontrollers in 32-pin packages. Featuring Arduino™ Nano connectivity, it allows easy expansion with specialized shields, while being mbed-enabled for seamless integration with online resources. The
board includes an on-board ST-LINK/V2-1 debugger/programmer, supporting USB reenumeration with three interfaces: Virtual Com port, mass storage, and debug port. It offers a flexible power supply through either USB VBUS or an external source. Additionally, it includes three LEDs (LD1 for USB communication, LD2 for power,
and LD3 as a user LED) and a reset push button. The STM32 Nucleo-32 board is supported by various Integrated Development Environments (IDEs) such as IAR™, Keil®, and GCC-based IDEs like AC6 SW4STM32, making it a versatile tool for developers.

*
* # Description
* This example demonstrates the use of IPD 2015 click board by toggling the output state.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and logger.
*
* ## Application Task
* Switches on all output pins state for 2 seconds, then switches them off, and turns them on one by one.
