The TPS73216DBVT belongs to the family of Linear Voltage Regulators. This three-terminal voltage regulator is widely used in various applications for providing a regulated voltage output with very low dropout voltage and high accuracy. In this article, we will discuss the application field and working principle of the TPS73216DBVT.

Application Field

The TPS73216DBVT is typically used in automotive systems such as engine control, powertrain control, low-side load switches, solar micro-inverter, and n-channel switch applications. It is also suitable for internal protection circuits in automotive systems and other applications. The TPS73216DBVT is able to drive n-channel power MOSFETs within the automotive range of -40 °C to +125 °C and must operate at current levels of up to 5A.

The device is also widely used in 12V & 24V supply voltage ripple detection and DC-DC converters. Its high current capability makes it suitable for primary and secondary power regulators. It is also suitable for frequency converter applications such as inverters, motor control, and switch-mode power supplies.

Working Principle

The TPS73216DBVT is a three-terminal linear voltage regulator. It features voltage feed-forward compensation, and its output voltage can be accurately regulated for a wide range of power conditions. Its high current capability enables it to drive up to 5A load without the need to include external transistors.

The device has a wide operating temperature range of -40 °C to +125 °C. It operates with a wide input range of 10.8V to 40V and a minimum dropout voltage of 1.3V. It uses an external feedback pin to regulate its output voltage. The voltage is determined by the ratio of the external resistors.

The TPS73216DBVT uses an internal temperature controlled voltage reference and PNP power transistors for its output stage. Its metal-oxide semiconductor field-effect transistor (MOSFET) for input protection and current limit protection helps to protect the device from any overvoltage or short circuit conditions.

It also features over-temperature shut-down, over-current protection, and short-circuit protection. Its low current consumption makes it ideal for applications that require energy efficient solutions.
