VN5772AK-E

The VN5772AK-E is a device formed by three monolithic chips housed in a standard SO-28 package: a double high-side and two low-side switches. The double high-side is made using STMicroelectronics^®VIPower^®M0-5 technology, while the low-side switches are fully protected VIPower M0-5 OMNIFET III. This device is suitable to drive a DC motor in a bridge configuration as well as to be used as a quad switch for any low-voltage application. The dual high-side switches integrate built-in non latching thermal shutdown with thermal hysteresis. An output current limiter protects the device in overload conditions. In the case of long overload duration, the device limits the dissipated power to a safe level-up to thermal shutdown intervention. An analog current sense pin delivers a current proportional to the load current (according to a known ratio) and indicates overtemperature shutdown of the relevant high-side switch through a voltage flag.The low-side switches have built-in non latching thermal shutdown with thermal hysteresis, linear current limitation and overvoltage clamping. In case of long overload duration, the low-side switches limit the dissipated power to a safe level up to the thermal shutdown intervention. Fault feedback for overtemperature shutdown of the low-side switch is indicated by the relevant status pin.
