TPS2082DRG4 is a Power Management Integrated Circuit (PMIC) for power distribution switches, load drivers, and energy metering devices. This device offers a battery, solar, or AC-powered, load driver/power switch system. This stand-alone device provides regulated power-on sequencing and current-limiting, temperature protection, integrated voltage regulation, and other features.

The TPS2082DRG4 has two independent, 2A and 0.3A output channels with the ability to drive an AC or DC load. The output voltage range is enable for a wide range of loads and (in the case of the Enable output) may be set to either 5V or 3V. The load selection feature allows the user to select the type of load connected to each of the outputs, so that the appropriate current protection features can be activated.

The TPS2082DRG4 is designed to provide controlled, on-demand power to loads, such as the LEDs used for accent lighting in the home (or elsewhere). It is optimized for efficient operation in low-power lighting applications. The TPS2082DRG4 can be used to drive incandescent, fluorescent, or LED lighting, as well as loads such as, small DC motors, small solenoids and relays, via its two output channels. The device supports both PWM- and analog-controlled outputs. The PWM output can be used to dim or switch the connected lighting load.

The TPS2082DRG4’s integrated hardware and software solutions provide advanced control and protection features. The Over-Voltage Detection (OVD) lockout circuit monitors the input voltage and shuts down the outputs if an over-voltage is detected. The device also monitors and protects the output voltage, as well as its temperature. The TPS2082DRG4 provides an integrated Timer for soft-start and shutdown. It also performs graceful shutdown by gradually reducing the load output in the event of an Over-Temperature or Over-Voltage Detection.

The device\'s integrated voltage regulator provides an output voltage of either 5V or 3V, depending on a selection by the user. Its wide operating temperature range—from -40°C to +85°C—makes the TPS2082DRG4 ideal for use in automotive and commercial lighting applications.

The TPS2082DRG4 is also suitable for applications such as mobile communications, embedded systems, peripheral accessories, and consumer products. This device can be used to provide power to things like GPS navigational equipment, multimedia systems, laptops, and printers. The TPS2082DRG4 helps system designers to improve the overall efficiency of their products, by providing accurate and reliable power dissipation data.
