Overview
The TPS2816DBVR is a single-channel high-speed MOSFET driver produced by Texas Instruments. It is part of the TPS28xx series, known for its high current drive capability and fast switching times. This device is designed to drive MOSFETs efficiently, especially in high-frequency switching applications. The TPS2816DBVR features an internal series regulator, allowing it to operate with supply inputs between 14 V and 40 V, and it includes an active pullup circuit on the input to eliminate the need for external pullup resistors when using open-collector PWM controllers.
