Isolators - Gate Drivers

The SI82396CB-IS1 is a highly efficient gate driver that allows a precise gate current to be provided. It is suitable for use in applications such as motor controls, inverters and industrial automation. It integrates isolation, isolation intelligence, and an on-chip DC-DC converter in a single package in order to provide cost-effective switching power solutions.

The features of this device make it highly attractive for applications where a precise gate current needs to be provided and also where an isolated signal needs to be outputted. Its compact size and low power consumption helps to keep system costs low. It also has an adjustable switching frequency of up to 1 kHz and it operates over a wide supply voltage of 4.7V to 13.2V. Additionally, it has a high drive current for quick switching, support for a wide range of PV panel sizes and a fast and reliable gate turn-off for improved safety.

The working principle of the SI82396CB-IS1 involves the provision of a high-current gate terminal, with an isolated power supply, to transition a downstream device from off to on or vice versa. The device utilizes an external high-impedance voltage divider for sensing internal bias voltage, providing accurate current and voltage readings. The device starts switching when a control voltage is applied to the gate terminal and monitors the voltage level when the device is in an “on” state to ensure there is a stable gate drive. The voltage level is then clamped to a predetermined threshold to ensure that the power dissipated does not exceed the device\'s thermal limit.

Overall, the SI82396CB-IS1 is an ideal solution for industrial motor control and inverting applications where a high current needs to be provided while ensuring isolation and stability. It is a highly cost-effective solution as it reduces the overall system cost and allows for a wide range of PV panel sizes to be supported. Its high-level integration of features helps to ensure that it is suitable for applications where precise switching is essential.
