VN5050J-E中文资料单通道高侧驱动器，用于汽车应用数据手册ST规格书

描述 Description

The VN5050J-E is a monolithic device made using STMicroelectronics VIPower 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). The device detects open load condition both in on and off state, when STAT_DIS is left open or driven low. Output shorted to VCC is detected in the off state.

When STAT_DIS is driven high, the STATUS pin is in a high impedance condition.Output current limitation protects the device in overload condition. In case of long duration overload, the device limits the dissipated power to safe level up to thermal shut-down intervention.Thermal shutdown with automatic restart allows the device to recover normal operation as soon as fault condition disappears.
