L9524C集成电路（IC）的电源管理-专用规格书PDF中文资料

L9524C属于集成电路（IC）的电源管理-专用。由意法半导体集团制造生产的L9524C电源管理 - 专用专用型电源管理集成电路 (PMIC) 用于电源的控制或操作，适合特定或小范围的目标应用，例如汽车气囊管理、电容器组平衡、AC 公共电力监控、存储器总线端接、接地故障检测、能量收集、小型引擎管理、处理器或芯片集专用电压调节、负载突降保护、触觉驱动器、热电制冷器控制等。

描述 Description

The L9524C is a control IC for up to six glow plugs of diesel engines. The glow plugs are switched by up to four external PWM-controlled N-channel Power MOSFETs or a single relay in high-side configuration.

Supply voltage, battery voltage, junction temperature, switches, currents through the glow plugs, and charge pump voltage are monitored.

A two-wire interface is used to communicate with the diesel engine management system.
