L9679PTR: The Pinnacle of Brake Dual H-Bridge Pre Driver Chip Technology A Revolutionary Integrated Circuit IC for Superior Performance and Durability

The L9679PTR is an innovative integrated circuit (IC) that can be used for advanced airbag or cut-off battery systems in automotive applications. The L9679PTR is the pinnacle of brake dual H-bridge pre driver chip technology, offering superior performance and durability.

The L9679PTR is a chip that integrates two H-bridge pre drivers, one for the brake solenoid and one for the brake switch, with a high power supply current of up to 1.5 A. The H-bridge pre drivers can control the brake solenoid and switch with high accuracy and efficiency, enabling a fast and reliable braking action. The L9679PTR also features an integrated PSI-5 satellite interface, which can communicate with up to four PSI-5 sensors for airbag deployment. The PSI-5 interface supports both synchronous and asynchronous modes, with a configurable data rate and frame length.

The L9679PTR is designed to meet the high standards and quality requirements of the automotive industry, such as AEC-Q100 qualification, ISO 26262 compliance, and ASIL-B capability. The L9679PTR has a robust and reliable design, with protection features such as overvoltage, undervoltage, overcurrent, overtemperature, and short-circuit detection. The L9679PTR also has a self-diagnostic function, which can monitor the status of the chip and report any faults or errors to the main microcontroller.

The L9679PTR is packaged in a 100-TQFP package, which has a compact and thin form factor, suitable for space-constrained applications. The L9679PTR can be soldered directly onto a printed circuit board (PCB) using a reflow or wave soldering process. The L9679PTR has a low parasitic capacitance and a high thermal performance, which improves the speed and efficiency of the circuit.

The L9679PTR is a versatile and cost-effective solution for various electronic applications that demand a high performance and a low profile. The L9679PTR is compatible with the L9678 and L9680 devices, which are part of the same family of automotive advanced airbag ICs. The L9679PTR is manufactured by STMicroelectronics, one of the world’s leading semiconductor companies, with a proven track record of innovation and quality.
