VNQ5050K-E集成电路（IC）的配电开关负载驱动器规格书PDF中文资料

描述 Description

The VNQ5050K-E is a monolithic device made using STMicroelectronics VIPower M0-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table).
