BU7962GW-E2 is an integrated chip featuring isolated high side/low side half bridge drivers, which is a great combination of high-voltage operations, small size and low cost. This chip is suitable for motor control and power switching applications. There are four high side outputs and four low side outputs which provide an output current of up to 1.5A.

The main features of the BU7962GW-E2provide fast switching, low ripple, and self-protection circuitry. It is widely used in automotive and industrial motor control applications, such as three-phase brushless DC motor drives, air compressors, fans and pumps, among others. It also finds applications in lighting control, power factor correction, DC-DC converters, etc.

The BU7962GW-E2 working principle is based on a power MOSFET and an integrated driver. The MOSFET switches the low side and high side of the bridge in two separate phases, which ensures a low gate charge and low gate leakage current. This eliminates the need for additional components, such as Schottky diodes, to protect against flyback or shoot-through currents. The integrated driver isolates the logic input from the switching output, which adds extra safety when operating in high-voltage and sensitive environments.

TheBU7962GW-E2 also features a built-in fault sensor, which monitors the status of the power supply, the output stage, and the temperature. If a fault is detected, the BU7962GW-E2 shuts down the outputs immediately, protecting the power stage components. It also has a thermal shutdown feature, which protects the device from excessive temperatures.

In conclusion, the BU7962GW-E2 offers a cost-effective and reliable method to control the high side and low side half bridge outputs of a motor control or power switching application. Its high voltage operation, small size, fast switching, low ripple, and built-in protection features make it an ideal choice for applications in automotive and industrial motor control as well as for power factor correction, DC-DC converters, and lighting control.
