Description

The VNQ5050AK-E is a monolithic device made using STMicroelectronics VIPower M0-5 technology. VNQ5050AK-E is intended for driving resistive or inductive loads with one side connected to ground. Active V_CC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table).

This VNQ5050AK-E device integrates 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 in a high impedance condition.

Output current limitation of VNQ5050AK-E protects the device in overload condition. In case of long overload duration, the device limits the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as the fault condition disappears.
