ICs ideal for automotive Auxiliary Motors in 48V MHEV

for automotive Auxiliary motors for 48V MHEV

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, uses smart technology to assist the engine's providing traction during startup and acceleration, and regenerates the battery during deceleration, is a low-cost operating vehicle that improves fuel efficiency. 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 IC's 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 Zero Crossing Latch hall effect ICs which operate ideally in BLDC motors.

Zero Crossing Latch Hall Effect IC S-57TZ S series
High-temperature operation
Zero Crossing Latch Detection
Thin package

Automotive, 150°C Operation, High-Withstand Voltage, High-Speed, Zero Crossing Latch Hall Effect IC S-57TZ S Series

The Zero Crossing Latch Hall Effect ICs transform the brushless DC motor market

A zero crossing latch Hall effect IC, is a latch type Hall effect IC that uses a world's first detection method, by detecting the output signal at the zero-crossing point where polarity changes. It is ideal for BLDC motor control, and unlike other Hall effect ICs, it is not thrown off by variations in magnetic flux density, and can maintain stable detection.
