H-Bridge 10 Click is a compact add-on board containing H-bridge outputs that let you control a DC motor to go backward or forward. This board features the MP6523, a triple, half-bridge, DMOS, output driver with integrated power MOSFETs that can drive up to three different loads from Monolithic Power Systems (MPS). The MP6523 is rated for an operating voltage range from 7V to 28V. It is SPI-configurable and has various diagnostic functions. Complete protection features include short-circuit protection (SCP), under-voltage protection (UVP), and thermal shutdown, alongside an onboard power supply existence-check circuit. This Click board™ is suitable as a multiple brushed DC motor driver for driving various loads in automotive and industrial applications, and more.
H-Bridge 10 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
H-Bridge 10 Click as its foundation uses the MP6523, a triple, half-bridge motor driver from Monolithic Power Systems (MPS). The MP6523 contains three MOSFET half-bridge outputs that can drive up to three different loads with separate controls for high-side or low-side MOSFETs from a standard serial data interface. It has a low quiescent current in standby mode, making it suitable for many applications. The input voltage ranges from 7V to 28V, with up to 0.9A output current capability per channel. Complete protection features include short-circuit protection, under-voltage protection, and thermal shutdown.
This Click board™ communicates with MCU through a standard SPI interface and operates at clock rates up to 3MHz, providing data in digital format of 16-bits. It also can be enabled or disabled through the EN pin routed to the PWM pin of the mikroBUS™ socket; hence, offering a switch operation to turn ON/OFF power delivery to the MP6523. It also provides a fault status indication signal, labeled as FLT and routed to the INT pin of the mikroBUS™ socket, alongside its red LED indicator marked as FLT to indicate different fault conditions such as current limit and thermal shutdown.
A unique addition that this board has is checking the existence of an external power supply. By adding resistors R4 and R5, the user can monitor and check the presence of an external power supply on the VS terminal via the voltage divider routed to the AN pin of the mikroBUS™ socket.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
