VND5E025AY-E数据手册集成电路（IC）的配电开关负载驱动器规格书PDF

描述 Description

The VND5E025AY-E is a double-channel high-side driver manufactured using STMicroelectronics®proprietary VIPower®M0-5 technology and housed in PowerSSO-36 package. The VND5E025AY-E is designed to drive 12 V automotive grounded loads, and to provide protection and diagnostics. It also implements a 3 V and 5 V CMOS-compatible interface for use with any microcontroller.

The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto-restart and overvoltage active clamp.

A dedicated analog current sense pin is associated with every output channel providing enhanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to VCCdiagnosis.

The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to share the external sense resistor with similar devices.
