The TPS22963CYZPR is a Constant-On Control Li+ Battery Load Switch with Integrated Power MOSFET. It is a member of Texas Instruments’ standby power supply system, and part of the System Load Switches Family. This particular device is a 4x3mm space-saving power distribution switch and it can deliver a maximum current rating of 1A. It is used in portable devices and other high-density systems that require a very low quiescent current and a wide supply voltage range.

The main features of the TPS22963CYZPR include low power operation with a current rating of 1A, the ability to turn-on/off with a single control signal, the ability to deliver higher voltages up to 20V, and very low quiescent current (less than 20µA). It is also a very versatile device as it can be used in various applications where low current and low voltage requirements are required, such as portable electronics and consumer electronics.

The typical application fields of TPS22963CYZPR include portable devices, consumer electronics, automotive systems, mobile phone accessories, audio and video equipment, and any other device requiring low power and low voltage. This particular device can also be used in automotive and industrial environments that require high-side current sensing, power distribution and current control. Additionally, because it is a high-side current switch, this device can be used to turn-on and off multiple external power supplies for various power needs in one system.

The working principle of the TPS22963CYZPR is based on a power MOSFET that is connected to a control signal input and an enable/disable input. When the enable/disable input is in the off-state, the power MOSFET is in its off-state and no current flows in the device. When the enable/disable is in the fully on-state, the power MOSFET is in its full on-state and current flows freely through the device. The control signal input is also connected to the power MOSFET and can be used to control the amount of current allowed through the device, as well as to turn-on/off the device. This particular device can be programmed to turn-on at a specific voltage level and can be used to control constant-on loads.

In conclusion, the TPS22963CYZPR is a very versatile device used in a variety of application fields, including portable devices, consumer electronics, automotive systems and more. The working principle is based on a power MOSFET with enable/disable and control signal inputs. These features make it an ideal solution for high-side current sensing, power distribution and current control applications that require low-power and low-voltage operation.
