VN800PSTR-E Typical application Circuitry Schematics

The VN800PSTR-E is a monolithic device made using Microelectronics Power technology. With one side linked to ground, it is meant to drive resistive or inductive loads. Device protection against low energy spikes is provided by an active VCC pin voltage clamp (see the ISO 7637 transient compatibility table). When CS_DIS is low, this device's analog current sense integrates and provides a current proportionate to the load current, which can be utilized to create advanced load diagnosis.

One potential application for the VN800PSTR-E is in a car headlight control system. Here, it would be used to control the power supplied to the headlights, allowing them to be turned on, off, or dimmed.

Here's a detailed interface of the VN800PSTR-E in this context:

1. Connect the OUT pin (Pin 5) to your headlight circuit. The power supply to the headlights will be managed via this output pin, which is what it is called.

2. A power source needs to be attached to the VCC pin (Pin 3). This is typically a car battery in automotive applications, but the exact power source would depend on the specific application.

3. Attach the GND pin (Pin 2) to the system's ground.

4. The IN pin (Pin 1) is used to control the state of the VN800PSTR-E. Connect this to a microcontroller or other control logic circuit.

5. The CS pin (Pin 4) is a current sense output that can be connected to an ADC input of a microcontroller for diagnostic purposes.

When designing a circuit with the VN800PSTR-E, consider the following:

- Protection: Ensure that the circuit is protected against overvoltages and transients. In automotive applications where the power supply might be noisy, this is especially crucial.

- Heat Dissipation: The VN800PSTR-E can generate a significant amount of heat when driving large loads. Verify that enough heat can be dissipated by the design.

- Decoupling: It's a good practice to place a decoupling capacitor close to the VCC pin to reduce noise.

- Load Type: The resistive or inductive loads can be driven by the VN800PSTR-E. Ensure that it is compatible with the load you intend to drive.

In summary, the VN800PSTR-E is a versatile high-side driver that can be used to control power to a variety of loads. With careful consideration of protection, heat dissipation, decoupling, and load compatibility, it can be used to effectively control a car's headlight system.
