描述
BD3378MUV-M是22通道的开关输入监测LSI。其作用是监测各通道所连接的机械开关的状态变化、使MCU产生中断。使用串行接口读取中断因素并写入内部寄存器。22通道的开关输入分为VPUB、VPUA两种电源系统，可按电池系统和电源控制系统分类使用。动作模式备有常规模式和睡眠模式两种。各模式可通过设定寄存器，使用开关端子连续监测设定和间歇监测设定。使用间歇监测设定时是以固定周期监测开关状态变化，可降低功耗。而且，通过使用各种电源系统时序动作和全部开关统一时序动作设定，还能实现低噪声动作。

Multiple Input Switch Monitor LSI for  
Automotive  
BD3378MUV-M  
General Description  
Features  
BD3378MUV-M is a 22-channel Multiple Input Switch  
Monitor IC that detects the opening and closing of  
mechanical switches. Once it senses a change in the  
status of a switch, it sends an interrupt signal to the MCU  
via a serial peripheral interface (SPI).  
The 22 switch inputs have two types of power supply,  
VPUB and VPUA. The VPUB and the VPUA power  
supplies can either be from a battery or from another  
power supply system. VPUB is the supply for the INB  
inputs while VPUA is for the INZ and INA inputs.  
BD3378MUV-M has two modes of operation, Normal and  
Sleep. In both modes, the internal registers can be set to  
make the device perform either intermittent or continuous  
monitoring of the switches.  
In intermittent monitoring, the switch status is monitored  
at regular time intervals, allowing the IC to operate with  
low power consumption. Also, operation with reduced  
noise can be achieved by enabling uniform sequential  
monitoring of all switches or sequential monitoring by  
power supply system.
