概览

NCV97200 是一款 2 输出单片稳压器，由 1 个降压稳压器和 1 个升压稳压器组成，具有多种监督功能，包括针对所有输出的窗口电压监控和窗口监督。此产品适用于 ADAS（高级驱动器辅助系统）应用，使用独立的电压参比和可调独立振荡器实现卓越功能。 40 V 非同步降压稳压器将电池电压转换为 3.3 V 输出，提供高达 3 A（峰值）的电流。此输出轨可用作非同步辅助升压转换器的低电压输入电压。辅助升压是固定的，用于为车内联网电路 (IVN) 提供低电流 5.0 V 轨。 所有内部 MOSFET 均为 N 沟道器件，使用一个自举电路驱动降压高压侧 MOSFET。两个 SMPS 输出均使用峰值电流模式控制，带有内部斜率补偿。该集成电路结合了为低电压门极驱动器提供电荷的内部稳压器。 NCV97200 是一款功能安全方案，多段可开发符合国际标准组织 (ISO) 26262 标准的安全系统所需的时间。该器件包括一系列集成的安全功能，如专用反馈参比、输出电压监控和窗口监督。
