TLE9845QX中文资料汽车级嵌入式功率芯片（系统芯片）数据手册Infineon规格书

描述 Description

Infineon's TLE9845QX product is a member of the TLE984x product family. It is a system on a chip (SOC) that provides the capability to drive a power PN MOSFET Half-Bridge. The Half-Bridge comprises of a p-channel high-side MOSFET and an n-channel low side MOSFET. TLE9845QX combined with the PN MOSFET half-bridge is designed to address smart DC brush motor control application like HVAC blowers or Fuel Pumps. The TLE9845QX enables a system solution that increases efficiency using smart power on demand control. The TLE9845QX enables a true mechatronic solution that places the electronic at the motor. As a result the external control signal (LIN or simple PWM) to the motor control does not produce any unacceptable emissions that can disturb other electronic components in the car
