TI TPS2021P

通用1不需要600mA

Overview

The TPS202x family of power distribution switches is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices are 50-m N-channel MOSFET high-side power switches. The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching. The charge pump requires no external components and allows operation from supplies as low as 2.7 V.

The TPS202x devices differ only in short-circuit current threshold. The TPS2020 limits at 0.3-A load, the TPS2021 at 0.9-A load, the TPS2022 at 1.5-A load, the TPS2023 at 2.2-A load, and the TPS2024 at 3-A load (see ). The TPS202x is available in an 8-pin small-outline integrated-circuit (SOIC) package and in an 8-pin dual in-line package (DIP) and operates over a junction temperature range of -40°C to 125°C.
