TPS22925BNYPHT Working Principle

The TPS22925BNYPHT is a low-side power switch designed to drive high peak currents. Its operating principle is based on N-channel MOSFET switching. This type of switch utilizes a P-Channel FET to provide the current control and a N-Channel FET to switch the output. The P-Channel FET is connected in series between the output voltage and ground, while the N-Channel FET is connected in parallel with the P-Channel FET but connected in series between the input voltage and ground. When the input voltage is applied, the N-Channel FET is turned on and the output load is supplied by the input voltage. When the output load current reaches the current limit set on the P-Channel FET, the P-Channel FET starts to turn on and the output voltage is regulated. This type of switch is efficient and provides excellent thermal performance due to its minimal power dissipation.

Conclusion

The TPS22925BNYPHT is a low-side power distribution switch offering excellent performance for applications that require high efficiency and high peak currents. It features an adjustable current limit, wide input and output voltage range, integrated low current detect circuit, and integrated temperature shutdown circuitry. The TPS22925BNYPHT is an ideal solution for distributed power applications in various industries such as consumer electronics, communications, automotive, industrial, and transport systems.
