The SN75477PE4 is an integrated circuit (IC) component primarily designed for use in the driver application circuit. It belongs to the family of quadruple half-H drivers, which are commonly used to drive brush type motors. The SN75477PE4 specifically offers advanced features and functionality, making it a reliable and efficient choice for various motor control applications. Here is an overview of its key features and specifications:
1. Quadruple Half-H Drivers: The IC contains four independent half-H drivers that can control up to four bidirectional DC motors or inductive loads.
2. High Voltage Capability: The SN75477PE4 supports a maximum operating voltage of 40 volts, making it suitable for driving motors requiring higher voltages.
3. High Current Outputs: Each of the four drivers can handle a continuous current of up to 650 mA, allowing it to drive a wide range of small to medium-sized motors.
4. Non-Inverting Inputs: The IC offers non-inverting inputs, meaning it simplifies the control signal interface by directly accepting input signals from logic gates or microcontrollers.
5. Outputs with Diodes: To protect the IC and external components from the back electromotive force generated by inductive loads, the outputs of each half-H driver include built-in diodes (flyback diodes).
6. Thermal Protection: The SN75477PE4 is equipped with built-in thermal protection circuitry that prevents damage due to excessive temperature, ensuring reliable operation and longevity
