Driver circuit

SSP55080 is a general LCD driver IC with 8COMx35SEG total output capacity of 280 bits, suitable for commonly used character/graphic LCD screens. SSP55080 support serial data interface(I2C).
The SSP8011AM is a low-cost and low-power single-key capacitive touch sensor IC, which provides single-channel touch sensing channels. Built-in voltage regulator circuit, few peripheral components, simple design, only a few components can complete the hardware design. Provides 2 output modes, high/low level output optional. It also provides a Reset function after a maximum button press time of 9 second. The sensitivity of the touch-sensitive keys can be adjusted as needed by adjusting the capacity of the external capacitance (CS), which increases the operability of the product and makes the design more flexible and versatile.
The SSP8012 is a low-power dual-key touch  sensor  IC. The operating mode is divided into Normal mode and Low Power mode.
ULN2003 is a single-chip integrated high voltage, high current Darlington tube array, The circuit contains seven independent Darlington tube drive single channel.  The circuit is designed with continuous diode, which can be used to drive relay,stepping motor and other inductive loads.  A single darlington collector can output 500mA current.  Higher output current capacity can be achieved by connecting darlington tubes in parallel.
SSP2617 is a single-channel H-bridge driver chip, providing an integrated motor drive solution for toys, robots, consumer goods and other low-voltage or battery-powered motion control applications.The maximum operating voltage of SSP2617 is 25V. It can provide a continuous output current of up to 3.0A and a peak output current of 5.0A. It also features over-temperature protection with a shut-off function and overcurrent protection (IOCP = 5.0A).
