LA7845N SANYO INTEGRATED CIRCUIT

The LA7845N is a monolithic integrated circuit manufactured by Sanyo, primarily designed for use in television vertical deflection output applications. This IC is specifically engineered to drive the vertical deflection coil in CRT (Cathode Ray Tube) televisions, providing the necessary current and voltage to accurately scan the electron beam vertically across the screen. The LA7845N is known for its robust design, high output power, and excellent linearity, ensuring a stable and distortion-free vertical display. Its integrated protection features enhance reliability and prevent damage from overcurrent or overvoltage conditions.

Key features of the LA7845N include its built-in ramp generator, which simplifies the design of the vertical deflection circuit by eliminating the need for external components. It also incorporates a vertical output stage with high current drive capability, allowing it to directly drive the deflection coil without the need for additional amplification. The LA7845N operates on a single supply voltage, typically around 24V, simplifying the power supply requirements. Its thermal shutdown protection prevents overheating, ensuring reliable operation even under demanding conditions. The IC is housed in a SIP (Single In-line Package), which provides efficient heat dissipation and easy mounting.

The LA7845N's specifications include a maximum supply voltage of 30V, a peak output current of 1.8A, and a typical power dissipation of 12W. The operating temperature range is typically from -20°C to +85°C, making it suitable for a wide range of environments. The IC also features a built-in flyback voltage protection circuit, which protects the output stage from damage caused by the high voltage generated during the flyback period. These parameters are crucial for ensuring the IC operates within its safe operating area and provides stable and reliable performance. The LA7845N's robust design and integrated features make it a popular choice for television manufacturers.

In practical applications, the LA7845N is primarily used in CRT televisions to generate the vertical deflection signal. It can also be used in other applications that require high-power, linear current drive, such as motor control and industrial automation.
