Страница 2: ...tion 1 Introduction The TPS2410 controls an N channel MOSFET to operate in circuit as an ideal diode The MOSFET source and drain voltages are monitored by TPS2410 pins A and C The TPS2410 drives the MOSFET gate high if VAC exceeds 10 mV and turns the MOSFET off if VAC falls below a threshold that is both programmable and dependent on the choice of TPS2410 or TPS2411 The TPS2410 has a turn off poin...
