The TPS2091DG4 is a advanced power management integrated circuit (PMIC) from Texas Instruments. It is a power distribution switch, load driver and is designed for applications such as mobile phones, tablets, automotive, consumer and industrial equipment. This device is ideal for applications that require control of higher voltage as well as low voltage loads, and correct voltage and current matching when switching on or off power.

The TPS2091DG4 loads are open-drain, high-power MOSFET drivers which can be used to power on/off devices up to 40V and 25A. It has 4 independent low side switches plus an additional monitor pin. This switch can be used to monitor current in various external power sources, and provide an output when current passes a pre-determined threshold. It also provides built-in protection features such as over-voltage, over-current and over-temperature protection.

The TPS2091DG4 device operates with an input voltage range of 4V to 20V. Its two integrated FETs features low on-resistance which minimizes power losses. It also features a very low off-state current, which reduces power consumption in low power modes. It has a 2.3mA (max) quiescent current which is low for a power switch and offers low power consumption.

The TPS2091DG4 is a single channel PMIC, and one of the main advantages of using this chip over other power switch drivers is its integrated low-side gate drivers. These gate drivers consist of four low side FETs (2 high side/2 low side) and a monitor output pin. The FETs\' integrated gate drive also reduces the power consumption of the PMIC by eliminating the need for external gate resistors.

The TPS2091DG4 is a power switch and load driver that offers a wide input voltage range and integrates protection features for over-voltage, over-temperature and over-current conditions. This switch also features low power consumption and a user-friendly integrated two-pole FETs gate drive with a monitor pin.

The TPS2091DG4 device is a reliable, cost-effective solution that provides superior current performance and overall system reliability. It is an ideal choice for applications that require control of higher voltage as well as low voltage loads and use of more complicated power distribution architectures. Additionally, this switch can also be used in combination with other power switching products, allowing a total system optimization solution.
