VND5004BSP30-E数据手册ST中文资料规格书

描述 Description

The VND5004B-E and VND5004BSP30-E are devices made using STMicroelectronics VIPower technology. They are intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp and load dump protection circuit protect the devices against transients on the Vcc pin. These devices integrate an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is high impedance. Output current limitation protects the devices in overload condition. In case of long duration overload, the devices limit the dissipated power to a safe level up to thermal shutdown intervention. Thermal shutdown with automatic restart allows the device to recover normal operation as soon as a fault condition disappears.
