The L9658TR is a specialized IC designed for use in the automotive industry. It is a low-voltage bidirectional motor driver and is used in applications such as electric windows, power-adjustable seats, and more. This IC integrates many integrated circuit components and offers significant application flexibility with its adjustable output current, overcurrent protection, and wide voltage tolerance range.

The L9658TR works on the basis of four different components. First, a power field-effect transistor (FET) is used to control the output current. This FET provides a low saturation voltage during forward and reverse operation, as well as an adjustable current level.

Second, the L9658TR integrates a low-side driver circuit which includes an output resistor and a voltage clamp circuit. This feature allows the FET to be driven low. This low-side driver is also adjustable and can be configured to drive the FET at any desired voltage level.

Third, an overcurrent protection circuit is included to ensure proper operation. This circuit provides an indication of excessive current when the output is disrupted by a short circuit.

Finally, the L9658TR integrates a wide voltage tolerance range, with operation accepted between 4.5V and 24V. This enables the IC to operate from a variety of power sources and allows for flexibility in the power requirements of the application.

The L9658TR provides a number of benefits for applications in the automotive industry. Its low-voltage operation, overcurrent protection, and adjustable output voltages make it ideal for a variety of applications, such as power-adjustable seats, electric windows, and remote controls. This IC offers designers flexibility and reliability, allowing for the safe operation of many automotive systems.
