Overview
The TPS2812P, produced by Texas Instruments, is a dual high-speed MOSFET driver from the TPS28xx series. This component is designed to deliver peak currents of up to 2 A into highly capacitive loads, making it suitable for high-frequency and high-capacitive applications. The TPS2812P features dual noninverting drivers and includes an internal regulator that allows operation with supply inputs between 14 V and 40 V, extending the overall circuit operation to 40 V. This device is available in an 8-pin plastic DIP (P) package and operates over an ambient temperature range of −40°C to 125°C.
