You can use dedicated power controller chips to add efficiency, flexibility and robustness to your high-power automotive applications. External MOSFETs can withstand higher voltages, avalanche events, load dump transients or reverse battery events, and the controllers provide additional protections with over-voltage and under-voltage lockouts. In safety-critical applications, integrated or independent microcontrollers (MCUs) can manage these systems to provide diagnostic functions or tracking telemetry or to simplify the creation of functionally safe board designs.
Switching regulators, commonly called DC/DC converters, are the most efficient devices to convert from one DC voltage to another. We offer a wide portfolio of efficient and compact, non-isolated DC/DC converters, controllers and modules, that range from single outputs to Power Management ICs (PMICs) with multiple outputs.
Charge pump ICs are simple and low-cost solutions for boosting voltage under light load conditions in small, battery-operated and other low-power applications. Unlike boost converters, charge pump ICs can operate without inductors, diodes or other external components and require only a few capacitors for energy storage. This reduces costs and saves board space in your automotive design.
MOSFETs, switches and relays can be used to control different under-hood and in-cabin automotive functions. In electrified vehicles, these drivers can also provide interfaces between digital controllers and power devices, including Gallium Nitride (GaN) and Silicon Carbide (SiC) power transistors, to create efficient, intelligent power management solutions for bus balancing, battery charging and other high-power vehicle modules. These solutions offer precise transition delays, fast transitions and accurate thresholds to make it easy to design high-quality automotive modules.
