The X-NUCLEO-IPS02A1 provides an affordable and easy-to-use solution for driving grounded loads (i.e. heating elements, solenoid driver, LED driver, light bulb driver, pumps relay replacement, and fans) in STM32 Nucleo projects.

This expansion board is compatible with the Arduino UNO R3 connector and supports the addition of other STM32 expansion boards with a single STM32 Nucleo board. The user can also mount the ST morpho connector.

The X-NUCLEO-IPS02A1 expansion board is based on the VPS2535H a double channel High Side Driver through a 3 V and 5 V CMOS-compatible interface and with multisense analog feedback and protections

The device VPS2535H integrates advanced protective functions such as the load current limitation protects the device in overload conditions. The device latches off in case of overload or thermal shutdown.

VPS2535H:

The VPS2535H is a monolithic device made using STMicroelectronics VIPower technology, intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes. The device integrates an analog current sense which delivers a current proportional to the load current. Fault conditions such as overload, overtemperature or short to VCC are reported via the current sense pin. Output current limitation protects the device in overload conditions.

The device latches off in case of overload or thermal shutdown. The device is reset by a low level pass on the fault reset standby pin. A permanent low level on the inputs and on the fault reset standby pins disables all outputs and sets the device in standby mode.


Application:

All types of resistive, inductive and capacitive loads.
