Half H Bridge Ic. A h bridge circuit made of tip3055 and tip2955 is used for the motor drive since the motor needs somewhat higher ampere rate. The device is designed to drive inductive loads such as relays solenoids dc and bipolar stepping motors as well as other high current high voltage loads in positive supply applications.
They support high currents and are designed for use in automotive and industrial applications. Another common variation adding a third leg to the bridge creates a three phase inverter. The sn754410 is a quadruple high current half h driver designed to provide bidirectional drive currents up to 1 a at voltages from 4 5 v to 36 v.
To reverse a dc motor you need both halves of an h bridge.
The half h bridge type is commonly abbreviated to half h to distinguish it from full full h h bridges. Novalithic is infineon s family of smart integrated motor driver ics. The device is designed to drive inductive loads such as relays solenoids dc and bipolar stepping motors as well as other high current high voltage loads in positive supply applications. To reverse a dc motor you need both halves of an h bridge.
