Power Management Integrated Circuits (PMICs) are essential components of power distribution, regulation and control circuits in consumer White Goods, computing and industrial systems. The most common PMICs are power distribution switches, load drivers and voltage regulators. Amongst these components, the TPS2090DG4, a single-channel, low on resistance switch, is widely used for power distribution in consumer and industrial applications.

• TPS2090DG4 Application Field: TPS2090DG4 is widely used in consumer and industrial applications. It is used as an interface in applications requiring higher voltage such as automotive and industrial equipment. It is also used in portable devices like mobile phones as a low dropping switch. In addition, it is also used in various audio amplifier components and is used for power switching when a specific signal is received.
• TPS2090DG4 Working Principle: The working principle of the TPS2090DG4 is based on the low on-resistance switch. The TPS2090DG4 is a single-channel power switch which operates on a supply voltage between –3.3 and –5V. The TPS2090DG4 is also featured with an open drainage gate and an internal resistor that makes it suitable for high switching frequency and low on-resistance. When the input signal is switched on, the power is delivered to the load. When the input signal is switched off, the switching action is terminated, allowing the load to be isolated from the power supply.
• TPS2090DG4 Features: The TPS2090DG4 features a wide range of operating power supply voltages, and it has low on-resistance, enabling it to reduce both power loss and heat generation. It also features an internal protection drain in order to protect against surge currents. Further features include integrated protection circuitry for overcurrent protection, quick POR capabilities for hot-plugging and current-limiting capability.
