Specific uses include power connect/disconnect switches in start/stop systems, semiconductor relays in ECUs and junction boxes in 12V battery system.
By combining a TPD7104AF gate driver and an N-channel power MOSFET, a semiconductor relay can be easily created thanks to its built-in charge pump. By adding a shunt resistor, the short-circuit protection and diagnosis functions can also be utilised.
The TPD7104AF features a very low output leak current for reverse battery condition: IREV=-1uA (min) (@ Tj=25°C).Housed in a compact PS-8 package the device measures just 2.8×2.9mm.
