The TPD7104AF is designed for automotive applications, such as power connect/disconnect switches in start/stop systems, semiconductor relays in ECUs (Electronic Control Units) 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. Other features of the new driver chip include short-circuit protection and diagnosis functions. The TPD7104AF also boasts a very low output leak current for reverse battery condition with IREV=-1uA (min) (@ Tj=25°C). Housed in a compact PS-8 package, the device measures just 2.8mm x 2.9mm.
