The 16201-Jxx is a multiple purpose intelligent relay driver ASIC designed for automotive applications. It uses the
RX16000-16 Bit parallel µC of Melexis.
A lot of integrated analogue and digital features allow to design different automotive applications using only a few
external components.
10 different interrupts allow to act on real time events, 4 interrupts are accessible via the pins.
The circuit is load dump protected for a 80V load dump pulse.
Due to License agreements with Melexis customers, the 16201Jxx is not free to use in electronic window
lifter applications.
