All Driver ICs comes under this category.
L293D Quadruple Half H Driver
L293D is a quadruple half H Bridge driver having high current capability which is commonly used in electronic projects for driving DC Motors, Stepper Motors, Relays, Solenoids etc. L293D can drive bidirectional currents up to 600mA at voltages ranging from 4.5V to 36V. It is compatible with Arduino Boards, Raspberry Pi, PIC, Atmel AVR, 8051 microcontrollers.
ULN2803A Driver IC
ULN2803A is a one of the most commonly used High Current, High Voltage Darlington Transistor Array IC. It contains 8 NPN darlington pairs with common cathode clamp diodes for each outputs for switching inductive loads. The current rating of each darlington pair is 500mA and you may connect two or more darlington pairs in parallel to increase current capability. This IC is commonly used in applications such as Relay Driving, Hammer Driving, Lamp Driving, LED and Gas Discharge Display Driving etc.
