TBD62387AFNG,EL application field and working principle

TBD62387AFNG,EL belongs to PMIC - Power Distribution Switches, Load Drivers category. It is a Power Management Integrated Circuit (PMIC) from Texas Instruments. It is designed to operate in a range of 8V to 40V for low voltage applications such as automotive applications. It provides system level power management and efficient power distribution for medium to high current application. The TBD62387AFNG,EL integrated circuit contains two power distribution switches, logic level shift capability and an adjustable current limit threshold. The power switch circuits are designed for efficient current sharing to reduce heat dissipation due to the current imbalance across one switch.

Features

The TBD62387AFNG,EL offers the following features:

• Wide input voltage range of 8V to 40V.
• Integrated logic level translation function.
• Easy scalability and versatility.
• Two integrated high-side MOSFETs.
• IO under-voltage lock out (UVLO) and control.
• Adjustable current limit threshold.

Applications

TBD62387AFNG,EL Integrated Circuit can be used in the following applications:

• Automotive infotainment system.
• Electric vehicle (EV) charging stations.
• Industrial industrial and consumer applications.
• Consumer appliances such as washing machines, dryers, and automated vacuums.
• Portable communication devices.
• Battery-powered devices.

Working Principle

The TBD62387AFNG,EL integrated circuit works on the basis of two different MOSFETs fully integrated in the circuit. The two MOSFETs are a high-side and a low-side. The high-side MOSFET is connected to the battery and is used to control the drain current while the low-side MOSFET is connected to the system supply and used to switch the drain current. The operation of both the MOSFETs is based on the on/off logic given by the logic input/output pins of the integrated circuit. The logic input/output pins of the IC also has the provision for logic level shift so that the voltage levels of the logic signals can be made compatible with the IC. The adjustable current limit threshold of TBD62387AFNG,EL integrated circuit is a safety feature and is used to set the maximum current allowed to pass through the two MOSFETs of the IC. It also provides over-current (OC) and Under-current (UC) protection. The two MOSFETs are also designed to provide optimal power sharing so that the current imbalance among them is minimized.
