Renesas unveils automotive intelligent power device

18 January 2023

Renesas Electronic Corp. has unveiled a new automotive intelligent power device (IPD) designed to control power distribution safely and flexibly inside vehicles.

The device, dubbed RAJ1810024H12HPD, uses a TO-252-7 package that reduces the mounting area by about 40% compared to traditional packages. The IPD allows for accurate detection of abnormal currents such as overcurrent, which allows engineers to design safe and precise power control systems capable of detecting abnormalities.

Overcurrent is just one protection function. Others include load short-circuit, overheat detection, sense current output and GND open protection.

IPDs have a longer life and are maintenance free compared to mechanical relays and can be placed anywhere in the vehicle.

Renesas said as the automotive industry moves toward centralized E/E architectures, IPDs will become a choice for power supply networks in vehicles due to their short, thin wires as well as a smaller solution for power distribution.

Other features include:

  • Low on-resistance (Ron) of 2.3 mΩ at 25° C (typ.)
  • Accurate current detection at low loads
  • Built-in charge pump
  • Self-diagnostic feedback by load current sense
  • Supports 3.3 V/5 V logic interface
  • Low standby current
  • Battery reverse connection protection with self-turn-on
  • Compliant with AEC-Q100 and RoHS automotive standards
