The function of Driver click is to accept a control signal on its inputs and drive heavier loads such as high power LEDs, relays or even DC motors.
It happens more than often that we want to activate relays, pulse high-brightness LEDs, or even drive various types of DC motors, in our embedded applications. The MCU is not capable of providing nearly sufficient current amount for any of these tasks. It can merely provide low-level control signals. Therefore, we need to use a proper driving circuit - such as the Driver click.
Driver click can accept the low-level control signal on its inputs and drive reasonably heavy loads, such as high power LEDs, relays or even DC motors. The main active element of this Click board™ is the DRV777 integrated motor and relay driver IC from Texas Instruments.
Driver click retains the connection flexibility of the DRV777 IC, offering a nine-pole spring terminal that can be used to implement and realize a wide range of different applications. Featuring kickback protection diodes, high impedance control inputs, input RC snubber network for improved reliability, pull-down input resistors that allow tri-stating, up to 2kV ESD protection, and more, this Click board™ is a perfect solution for developing various types of motor driving applications, regardless of whether it is a stepper motor, brushed DC motor, brushless motor, or a combination of these. A special feature of this Click board™ is the possibility to combine integrated drivers in parallel, allowing to sink up to 1A of current.
