描述
BV2HD045EFU-C是利用独有的过电流保护功能,可独立保护系统免受过电流影响的智能高边开关。普通产品仅支持启动时的浪涌电流保护,启动后的稳态电流使用微控制器和过电流检测IC等进行过电流保护,受与智能高边开关输出端的后段电路之间的相性影响,有失控的可能性。而新产品则可以独立地保护系统免受浪涌电流和稳态电流中的过电流的影响,因此,与普通产品的解决方案相比,可提供可靠性高、部件数量少的解决方案,有助于打造更安全的系统。另外,过电流保护的范围还可以通过外置部件进行自由调整,因此可使用于各种系统。

Datasheet  
IPD Series  
Automotive 2ch 45 mΩ High-Side Switch  
with Variable OCD and OCD Mask Function  
BV2HD045EFU-C  
General Description  
Key Specifications  
BV2HD045EFU-C is  
a
2-ch high-side switch for  
Power Supply Voltage Operating Range: 6 V to 28 V  
automotive application. It has built-in over current  
protection function, thermal shutdown protection function,  
open load detection function and under voltage lockout  
function. It is equipped with diagnostic output function for  
abnormality detection. An external component can  
arbitrarily set the over current limit and the time to limit to  
achieve the optimum over current protection for the load.  
On Resistance (Tj=25°C):
