A4407是一种汽车电源管理IC，采用2.2MHz恒定的准时（COT）降压预调节器，提供5 V线性稳压器，A 5 V跟踪/保护的线性稳压器，A 3.3 V线性FET控制器/驱动器，和1.2 V / 1.5 V / 1.8 V线性FET控制器/驱动器。A4407提供了一个引脚，用于将5 V跟踪调节器设置为3.3 V或5 V输出的销钉。降压的随机时间是内部调整为VIN以维持2.2 MHz开关频率的函数。在提供线性稳压器之前，通过使用降压预调节器降低输入电压来实现高效操作。A4407在高温环境中为CAN和微处理器电源提供设计，适用于引擎盖应用。亚博尊贵会员
The switching regulator is designed to operate at a nominal switching frequency of 2.2 MHz. The high switching frequency enables the customer to select low value inductors and ceramic capacitors while avoiding EMI in the AM frequency band. Protection features include: undervoltage lockout, pulse-bypulse current limit, LX short circuit protection, and thermal shutdown. In case of a shorted load all linear regulators feature foldback overcurrent protection. In addition, the V5P output is protected from a short-to-battery event. The A4407 features both a logic level and a high-voltage (current and voltage limited) enable input. The A4407 also features a power-on-reset (NPOR) output with adjustable delay for microprocessor control.
A4407以低轮廓（1.1毫米）24引线TSSOP封装供应，具有暴露的垫，用于增强散热（后缀LP）。包装是铅（Pb），可免费提供100％哑光锡引线框架电镀。
