半桥驱动器IC，集成 Arm® Cortex® M0

综述

 

With our single phase solution simple loads can be addressed either via PWM or LIN. To achieve a smallest in class footprint, Infineon provides a system-on-chip (SoC) solution built on 32-bit Arm® Cortex®-M0 core and which offers a complete integration. TLE9845Qx is coming in a leadless VQFN package (7x7mm²) helping to save PCB space. This highly integrated product provides the capability to drive a power PN MOSFET Half-Bridge. The Half-Bridge is built up with a P-channel MOSFET in high-side and an N-channel MOSFET in low side position. The TLE9845Qx combined with the PN MOSFET half-bridge is designed to address smart DC brushed motor control applications like HVAC blowers or fuel pumps. The system solution increases efficiency using smart power on demand control, and 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.

TLE9845Qx is pin-compatible to our relay driver IC family and supports a platform approach and helps to reduce development time.
