Global warming, air pollution, and other environmental issues have accelerated the trend away from the internal combustion engine (ICE) towards EV, PHEV, HEV and other environmentally conscious vehicles. The 48V MHEV is a low-cost operating vehicle that improves fuel efficiency. It uses smart technology to assist the engine drive during startup and acceleration, and regenerate the battery during deceleration. Presently, the 48V MHEV is being introduced to the market mainly by European automakers, due to the higher demand from that region.
The 48V MHEV operates on 48V batteries to drive auxiliary motors for its electric compressors, electric turbochargers, electric pumps, fan motors, etc., which contribute to an improved fuel economy.
ABLIC has produced a number of high caliber ICs that are ideal for 48V MHEV auxiliary motor operation. ABLIC offers a comprehensive range of products, such as: LDOs with built-in watchdog timers for monitoring MCUs, Primary DC-DC with a built-in spread spectrum clock generation circuit for low EMI, LDOs for sensor power supplies and ZCL™ hall effect ICs which operate ideally in BLDC motors.
