TPS5602IDBTRG4

The Texas Instrument\'s TPS5602IDBTRG4 is a special purpose voltage regulator specialized for use in embedded designs. It features an input voltage of 1.5V to 5V, to output of 3.2V, and a load current of up to 4A. With a small WLCSP (wafer-level chip-scale package) of 2mm x 2mm, it is suitable for designs where space is at a premium. Additionally, its low shutdown current of 1.25µA makes it a good choice for battery powered or low-power applications.

The device has a simple two-pin configuration and is controlled by an integrated P-channel MOSFET on the output side. This allows the regulator to achieve high accuracy and low noise performance due to the inherent low Iq (quiescent current) design. It also has overcurrent protection through a current-limiting MOSFET, as well as overvoltage protection from an external avalanche diode.

In terms of applications, the TPS5602IDBTRG4 voltage regulator can be used in a wide range of embedded designs. It is particularly suitable for automotive applications, such as side mirrors and other vehicle control units, as well as industrial applications, including data loggers, industrial automation and more. Additionally, it can be used in medical equipment, lighting, security systems and more.

The working principle of the TPS5602IDBTRG4 is based on the use of a P-channel MOSFET connected to an external diode on the output side, as mentioned above. The P-channel MOSFET is driven by an internal comparator, which is set to a desired output voltage. The external diode ensures overvoltage protection, while the current-limiting MOSFET provides overcurrent protection. This simple two-pin configuration is able to achieve high accuracy and low noise performance, while still offering the flexibility to customize the output voltage for a specific application.

For all the above reasons, the TPS5602IDBTRG4 is an excellent choice for embedded designs that require a special purpose voltage regulator. Its small WLCSP package, combined with its high accuracy and low noise performance, allows for an efficient and reliable solution that meets the needs of demanding applications.
