The RAJ2810024H12HPD is available in the TO-252-7 package which reduces the mounting area by about 40% compared to the conventional TO-263 package product. It measures 6.10 x 6.50mm, excluding pins.

Intended for use in vehicles equipped with next-generation E/E (electrical/electronic) architectures, it has a current detection function for abnormal currents such as overcurrent and detects abnormal currents even at low loads, says the company, for precise power control system design that can detect even the smallest abnormalities.

Other features are built-in charge pump, self-diagnostic feedback by load current sense and load short circuit, overheat detection, sense current output and GND open protection.

The single channel, high side IPD has low Ron of of 2.3mΩ at 25°C (typical). The intelligent power device (IPD) addresses E/E architectures as they evolve in automotive design. In a conventional distributed E/E architecture, power supply from the battery is distributed to each electronic control unit (ECU) via long, thick wires from a power box consisting of mechanical relays and fuses. IPDs have a longer life and are maintenance-free compared to mechanical relays, so they can be placed anywhere in the vehicle. As the automotive industry moves toward centralised or zoned E/E architectures, IPDs offer flexible power supply networks using shorter, thinner wires.

The RAJ2810024H12HPD supports 3.3/5.0V logic interface and complies with AEC-Q100 and RoHS automotive standards.

The RAJ2810024H12HPD is available today in sample quantities with mass production scheduled in Q1 2024.
