With the aim of reducing CO2 emissions, turbocharger systems are evolving from exhaust gas driven to electric driven forms for use in Mild Hybrid Electric Vehicles (MHEV). The superchargers improve the response of the engines at low revolutions and also enhance performance. An electric supercharger responds instantaneously, removes lag and improves the vehicle’s acceleration.
ST is enabling the electric supercharger application with its extensive product portfolio including an integrated solution for electric motors using the 48 V 3-phase driver L9907 and an 32-bit automotive MCU; the offer is completed by LDO voltage regulators, protections and very low on-state resistance N-channel Power MOSFETs.
