FP4SDSD02M4 is a kind of integrated circuit, which are widely implemented in various sectors. It is mainly used as a switching regulator and consists of multiple active elements such as field-effect transistors (FETs) and integrated digital circuits. This is particularly applicable in automotive electronics control system. It is commonly used as a voltage regulator in many applications such as battery management systems, battery chargers, ignition systems, voltage regulators, motor control systems, and other automotive electronic systems. FP4SDSD02M4 has the following characteristics:

• It has high current capability capacity up to 2A and is suitable for 12V vehicle systems.
• It has low quiescent current (QC) requirements, of only 1mA and 1.2 mA respectively for battery disconnection and battery reconnection.
• It is designed for automotive electronics and is robust and reliable in harsh environment.
• It provides over temperature disconnection protection and undervoltage lockout function.
• It can handle various input supply voltages (VIN) range from 3.5 V to 20 V.

The FP4SDSD02M4 is a two-wire control power switch with integrated disconnection protection, under voltage lockout and over temperature protection. Its basic operation can be explained by the following three stages:

1. Regulation stage

This stage begins once the supply voltage is greater than the turn-on threshold voltage. During this period, the FP4SDSD02M4 will turn on and the voltage across the device will be regulated to the nominal value of Vout which is also the maximum power supply voltage. This stage is very important because it is responsible for providing a stable working condition for the load.

2. Disconnection stage

In this stage, the FP4SDSD02M4 will turn off to disconnect the power supply voltage from the application or device when the supply voltage falls below the under voltage lockout threshold voltage (UVLO). This is to prevent the battery from being over discharged. This stage is also known as the “protection” stage.

3. Reconnection stage

Once the supply voltage is above the turn-on threshold (ViH) and the temperature is above the over temperature lockout threshold (Trip), the FP4SDSD02M4 will turn on to restore the power supply voltage and reconnect the application or device to the power supply.

FP4SDSD02M4 is mainly used in automotive electronics control system. It is used to adjust the voltage across the device such that it is at a nominal value of Vout. It also provides protection against over temperature and undervoltage conditions by disconnecting the load from the power supply. This highly efficient and reliable power switch is suitable for 12V automotive systems, making it an ideal choice for automotive manufacturers.
