MPS推出车规级TFTLCD偏压驱动IC，可广泛适用多种车载显示屏场景

Core Viewpoint - MPS Chip Source Systems (NASDAQ: MPWR) has launched the automotive-grade thin-film transistor liquid crystal display (TFTLCD) bias driver MPQ5613D-AEC1, which has received AEC-Q100 Grade 1 reliability certification and is suitable for various automotive display applications such as instrument panels, central control screens, and head-up displays (HUD) [1][7]. Group 1: Product Features - The MPQ5613D-AEC1 supports an input voltage range of 2.7–12V, with a maximum output current of 500mA for boost and buck-boost modules, 50mA for both positive and negative charge pump modules, and 25mA for the VCOM buffer [2][9]. - It integrates four output channels, a VCOM buffer, and gate voltage shaping functions, making it specifically designed for automotive TFTLCD applications [8][1]. - The device features a wide output voltage range, with the boost module adjustable from 2.7V to 21.8V and the buck-boost module from -0.7V to -16.6V, allowing it to drive larger panel sizes [2][9]. Group 2: Application and Adaptability - The MPQ5613D-AEC1 supports six adjustable switching frequencies (up to 3MHz) and offers spread spectrum functionality, frequency synchronization, and phase control (180°) to reduce EMI [3][10]. - It can be configured through an I2C communication interface to adapt to various application scenarios by controlling the power-up and power-down sequences of VDDP, VDDN, VGH, and VGL [3][10]. Group 3: Safety and Design - The device includes robust protection features such as input under-voltage lockout (UVLO), cycle-by-cycle current limiting, over-temperature protection (OTP), under-voltage protection (UVP) for VDDP/VDDN/VGH/VGL, output over-current protection (OCP) for VCOM, and current limiting for VDDP [6][11]. - The MPQ5613D-AEC1 is designed in a compact QFN (4mm x 5mm) package, significantly reducing PCB area and minimizing the use of external components, thus saving BOM costs [12][6]. Group 4: Additional Solutions - MPS also offers various backlight solutions, including global dimming and local dimming products, to meet different customer needs for automotive TFTLCD applications [13][14].
