TPS2816DBVT Application Field and Working Principle

The TPS2816DBVT is a switch-mode power supply gating driver from Texas Instruments (TI). It is a monolithic circuit designed to drive and protect both low-side and high-side MOSFETs or other transistors in DC/DC or other switch-mode power supplies. It can be used in a variety of applications, including computer systems, telecom systems, motor-drive amplifiers, power-supply controllers, instrumentation, and audio amplifiers.

The TPS2816DBVT is a dual-channel, symmetrical gate driver designed to increase efficiency in applications with both low-side and high-side MOSFETs. This driver is capable of operating in either linear or switching mode and is designed to reduce switching losses and eliminate dead-time delays. It has a maximum total gate drive output current of up to 12.5A, with a rise time as fast as 6ns and a fall time as fast as 18ns. This driver includes an independent low-side gate drive voltage boost circuit to protect the gate-drive circuit against short circuits or sudden transients on the low-side gate. It also includes an input undervoltage lockout circuit that prevents the device from powering up until the input voltage reaches the level needed to protect the MOSFETs.

The TPS2816DBVT provides circuit designers with the flexibility and control needed to maximize their design goals, helping to ensure that their circuits will function as expected in all operating conditions. This driver has a low-saturation gate drive voltage of 350mV, so it can be used in applications where low-dropout gate drive devices are necessary. It also features a wide selection of dead times, ranging from 0-400ns, allowing for flexibility in matching a desired current limitation and voltage compensation level. Its independent low-side gate drive voltage boost circuit helps eliminate current circulation, as well as minimize switching losses and improve ride-through capability.

The TPS2816DBVT is designed to be used in applications that require a high-power gate driver solution. With its robust feature set, it provides the designer with the control and flexibility necessary to increase efficiency and reduce switching losses. This makes it an ideal solution for a variety of applications in computer systems, telecom systems, motor-drive amplifiers, power-supply controllers, instrumentation, and audio amplifiers.
