The TPS2067D is a monolithic integrated circuit that efficiently manages power distribution, enabling the sharing of limited power resources among a variety of electronic loads. It is a versatile power distribution switch and load driver that helps maximize system efficiency and minimizes power supply design complexity. This highly integrated circuit also features a wide variety of additional features, allowing for greater application flexibility and decreased bill of materials in power-sensitive systems.

The TPS2067D is a dual-channel power distribution switch optimized for applications requiring programmable power control and load management. Its dual power distribution channels, shared 3A load driver, and 6-bit programmable power control provide an ideal solution for optimal power sharing and distribution in systems with multiple and/or lower power band-limited sources. The integrated load driver can be used to control a remote FET. This allows the TPS2067D to manage power distribution without the need for an additional external load driver. The device also offers a two-stage power sequencing capability that provides the flexibility to configure and control power-up or power-down timing for multiple sources, providing improved system control and optimized power efficiency.

The TPS2067D has been designed to provide power management in a wide variety of end equipment. The device features a wide input voltage range, wide operating temperature range, and low quiescent current. The TPS2067D is ideal for end equipment such as telecom base stations, networking, imaging applications, consumer electronics, industrial automation, and medical instruments.

The working principle of the TPS2067D is based on its self-biasing cascode architecture and its power control implementation. This allows the TPS2067D to manage power distribution efficiently by enabling the sharing of limited power resources among multiple and/or lower power band-limited sources. This can be done without any involvement of an external load switch FET. The TPS2067D is also capable of sequencing multiple sources, thus providing a two-stage power sequencing capability. This two-stage power sequencing feature enables the efficient control of power-up and power-down timing in power-sensitive systems.
