특징
-
SolidSwitch 2 Click as its foundation uses the L9026, an automotive multi-channel relay driver optimized for automotive relay and LED applications from STMicroelectronics. Eight channels of the L9026 represent two high-side and six configurable high-side/low-side drivers, which can be driven by an SPI interface or by two dedicated parallel inputs (IN0 and IN1 pins routed to the PWM and INT pins of the mikroBUS™ socket). Operating from an external power supply from 3V up to 18V, it provides a maximum current of 1A on its output terminals making this board an excellent choice for automotive applications (LEDs and relays) compatible with resistive, inductive, and capacitive loads.
As mentioned before, this Click board™ communicates with MCU through a standard SPI interface used to control and configure the loads and the device. The L9026 also offers advanced diagnostic and protection features such as short-to-ground, open load, overcurrent, and overtemperature detections, with status feedback of all diagnostic functions provided via the SPI interface.
Besides, the L9026 also features Idle mode for reduced current consumption, controlled via IDL pin routed to the AN pin of the mikroBUS™ socket and the "Limp home" mode. This mode allows using two selected drivers in particularly faulty conditions, such as SPI fault, micro fault, or supply undervoltage. The device can guarantee operations under a cranking scenario with a supply voltage down to 3V and ensures a low quiescent current under reset conditions.
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 containing easy-to-use functions and an example code that can be used, as a reference, for further development.
