The TPS2066D is a power distribution switch, load driver integrated circuit from Texas Instruments. It provides a power distribution system to power multiple loads from a single source. It includes integrated logic and PMOS pull-up MOSFETs. TPS2066D is capable of withstanding a large voltage drops caused by high-current load switching. The programmable current limit feature permits the current limit to be changed by a single resistor.

The TPS2066D is a monolithic integrated circuit which integrates two high side PMOS switches which can provide a 3.25A peak current and a 6A peak current limit. The integrated switching elements are designed to reduce power loss due to conduction and switching losses. The integrated logic provides low power operation and programmability.

The TPS2066D provides two channels for distributing power. Each channel has a power switch and a load driver. The power switch is controlled by a logic signal, and the load driver is controlled by an analog reference voltage. The two channels can be independently controlled, and the power switch output voltage is adjustable.

The power switch has three states, ON, OFF and TRISTATE. When the logic signal is high the power switch will be ON and when the logic signal is low the power switch will be OFF. The tristate mode can be activated by setting the logic signal low and then applying an external voltage to the input of the power switch.

The load driver is designed to safely drive a wide range of loads. The load driver is provided with separate control for each of its two channels. The control voltage is applied to the load driver input, and the output of the load driver is adjusted accordingly. The load driver has the advantage of allowing a load to be driven at a wide range of voltages, from just a few millivolts to tens of volts. It also provides current limit protection and glitch-free switching.

The TPS2066D also contains an integrated MOSFET to provide overcurrent protection. The overcurrent protection circuit monitors the current in the load and when the current exceeds a predetermined value the integrated MOSFET will turn off the power switch, thus preventing damage to the load.

In addition to the integrated MOSFET and the power switch, the TPS2066D also contains two analog reference voltage inputs. These inputs control the output voltage of the power switch and the load driver. The voltage applied to these inputs is controlled by a single external resistor.

The TPS2066D is ideal for applications requiring a compact power distribution system that can provide a large amount of power to multiple loads. It is ideal for applications such as industrial control systems, DC-DC converters and automotive applications. The integrated logic and overcurrent protection provide safe and reliable power distribution and control.
