The Texas Instruments TPS65163RGZR is a power management integrated circuit (PMIC) specifically designed for 5V/3V3 power supply applications. This device integrates two independent regulated output levels and four high-side FETs in a small form factor. Furthermore, this device is characterized by a low stand-by current of less than 1μA, making it suitable for large-scale power applications.

The TPS65163RGZR provides a 5V/3V3 dual regulated power supply with four power FETs. It includes an adjustable delay option for the power on sequencing. Output voltage of the power FETs can be adjusted between 3.7V and 5.5V. The switching time is typically 0.5 μs, with a maximum of 1 μs. It also provides an adjustable current limit of up to 1.2A.

The device can be enabled in either power-on reset or manual reset. The power-on reset (POR) is used when the application needs to be powered on before other electronics are powered up. For manual reset, a digital input is available to start or restart the device safely. This feature is used in applications where an application starts or restarts safely without any additional external reset control.

The TPS65163RGZR also provides two input pins (ADJ and RESET) to adjust the output levels and control the FETs. Input levels are adjustable by controlling the two external components connected to them (an external resistor and a capacitor, respectively). The ADJ pin adjusts the output voltage up to 1.2V. The RESET pin is used to control the power-on background power-down behavior.

The FETs provide overload, short-circuit, and inrush protection thanks to their integrated current threshold protection. The FETs switch on and off in response to the ADJ pin and RESET pin, respectively. This allows for greater power output than traditional power supply designs. Furthermore, the TPS65163RGZR includes under-voltage and over-voltage protection, which prevents the power supply from becoming over-temperature, over-current, and over-voltage.

The TPS65163RGZR is suitable for a wide range of applications, including laptops, tablets, phones, portable gaming systems, and industrial control systems. Its wide range of features makes it an ideal choice for power management in both high-current and low-current applications. Furthermore, its small form factor makes it a great option for embedded applications.
