Frequently Asked Questions
What is the drain-source voltage rating and on-resistance of the TP2104N3 P-channel MOSFET?
The TP2104N3 has a 40 V drain-source voltage rating and 6 ohm RDS(on), providing adequate breakdown protection and moderate conduction losses for load switching in battery-powered and low-voltage embedded system applications.
In which circuit topologies does the P-channel TP2104N3 simplify implementation compared to N-channel alternatives?
The TP2104N3 simplifies high-side switch designs at supply voltages up to 40 V because P-channel MOSFETs turn on when the gate is pulled low relative to the source, eliminating the need for a charge pump or bootstrap circuit required by N-channel high-side switches.
What are typical applications for the TP2104N3 in battery-powered portable designs?
Typical applications include battery reverse-polarity protection, load switching, power multiplexing, and soft-start circuits in portable electronics and IoT nodes where the 40 V 6 ohm P-channel MOSFET controls supply rails up to several amperes.
Can TP2104N3 be driven directly from 3.3 V or 5 V microcontroller GPIO outputs?
Yes, the TP2104N3 is designed with a low gate threshold voltage that allows direct drive from 3.3 V or 5 V logic-level GPIO outputs, enabling microcontroller-controlled switching of 40 V load lines without additional level-shift circuitry.
