VN5050J-E Single channel high side driver for automotive applications Features Max supply voltage V 41V CC Operating voltage range V 4.5 to 36V CC Max On-State resistance (per ch.) R 50 m ON PowerSSO-12 Current limitation (typ) I 19 A LIMH (1) Off state supply current I 2 A S Application (1) Typical value with all loads connected. All types of resistive, inductive and capacitive Main loads Inrush current active management by power limitation Description Very low stand-by current 3.0V CMOS compatible input The VN5050J-E is a monolithic device made using STMicroelectronics VIPower technology. It Optimized electromagnetic emission is intended for driving resistive or inductive loads Very low electromagnetic susceptibility with one side connected to ground. Active V pin CC In compliance with the 2002/95/EC voltage clamp protects the device against low European directive energy spikes (see ISO7637 transient Diagnostic functions compatibility table). The device detects open load Open drain status output condition both in on and off state, when STAT DIS is left open or driven low. Output shorted to V is On state open load detection CC detected in the off state. Off state open load detection Thermal shutdown indication When STAT DIS is driven high, the STATUS pin is in a high impedance condition.Output current Protections limitation protects the device in overload Undervoltage shut-down condition. In case of long duration overload, the Overvoltage clamp device limits the dissipated power to safe level up Output stuck to V detection CC to thermal shut-down intervention.Thermal shut- Load current limitation down with automatic restart allows the device to recover normal operation as soon as fault Self limiting of fast thermal transients condition disappears. Protection against loss of ground and loss of V CC Thermal shut down Reverse battery protection (see Figure 27) Electrostatic discharge protection Table 1.
