TPS2061CDGNR

TPS2061CDGNR is a single-channel power switch and load driver from Texas Instruments (TI). It is part of TI\'s PMIC (Power Management IC) family categorized as Power Distribution Switches, Load Drivers. The device is ideal for general power distribution and load driving applications. It is offered in a 14-pin LLP (Leadless Leadframe Package), with a variety of voltage, temperature and current ratings. It contains a P-Channel power MOSFET, a low-noise amplifier internally biased, an internally fixed 100kHz clock, an adjustable soft-start, high-speed logic inputs, an under-voltage lockout, and fault protection.

One of the main features of the TPS2061CDGNR is its light weight and small size. It is designed to be much smaller than traditional power switches, providing portability and flexibility for many applications. Additionally, the device is quite flexible and configurable, with several programmable settings, enabling the designer to customize it for the specific application. Furthermore, the device provides a wide range of voltage and current ratings, from 0.4V up to 24V, making it suitable for both low- and high-voltage applications. Therefore, it can be used for a diversity of applications including AC/DC power supplies, automotive, lighting controls, industrial and consumer electronics.

Regarding the working principle, the TPS2061CDGNR is powered through the VIN pin and uses a single-channel P-channel MOSFET to control the load. The load current passes through the MOSFET when the switch is in the ON state, and it is limited by the current setting resistor (CSR). The CTRL pin is used to control the switch, with a low voltage disabling the switch and a high voltage enabling it. The device contains an adjustable soft-start, high-speed logic inputs, an under-voltage lockout, and fault protection circuitry to protect it from over-current and under-voltage conditions. Finally, the TPS2061CDGNR also features an integrated logic level-shifting circuit to ensure that the voltage applied to the CTRL pin is always above the VIN voltage.

In summary, the TPS2061CDGNR is a versatile, configurable, and extremely small single-channel power switch and load driver for general power distribution and load driving applications. It offers wide voltage, temperature, and current ratings, making it suitable for a variety of applications. Additionally, the device contains an integrated logic level-shifting circuit and a variety of safety features, which help ensure that the device is properly protected from short circuit and over-voltage conditions.
