The UCC5350SBDR is a high-frequency, high-current Gate Driver IC specifically designed for switching AC and DC loads. The device is an isolator that combines high-voltage isolation with logic level translation, enabling it to control non-isolated logic signals into a fully isolated powerful Gate Driver.

The UCC5350SBDR is an ideal solution for applications such as switches, relays, motors, solid state relays, and solenoids that require high-current driving capability. The device features a high pulse width capability of up to 2 A, with a maximum peak current rating of 3A. The Gate Driver is also designed to withstand high ESD voltages, up to 4KV.

The UCC5350SBDR Gate Driver provides user-defined isolation, allowing the user to configure the degree of isolation to the application requirements. The device includes a high voltage side with an internal/external VDD power supply, a low voltage side (VSS) with an internal VSS power supply, and a control signal in-out port. The UCC5350SBDR generates high voltage isolated power providing up to 4KV of isolation. The logic side of the device is operated at low voltage logic, typically 5V.

In addition to its high-current driving capability and isolation, the UCC5350SBDR also features a wide operating temperature range of -40°C to +105°C, making it suitable for a variety of conditions. The Gate Driver is designed for high-reliability operation with a hard-tin plating on the exposed metal electrodes, a pre-fitted thermal pad, and a thick-film solder resist pattern.

The UCC5350SBDR provides an output voltage of up to 500V, with a minimum driving voltage of 4.5V. The device also features high-frequency switching capability with a maximum switching speed of 25kHz and a minimum pulse width of 50ns. The high-frequency switching reduces the conduction loss and enables the Gate Driver to provide faster switching time.

The UCC5350SBDR Gate Driver is designed to provide high current with low resistance switching. The device features a low on-state resistance (<1.7Ω) and a low off-state resistance (<0.5Ω) capability, thus reducing the power dissipation of the Gate Driver. The device also features a Self-Protection Function with a Turn-on Delay and an Under-Voltage Lockout (UVLO) to guarantee safe switching.

Finally, the UCC5350SBDR features logic-level safety by incorporating voltage clamps on the control signal path, thus protecting the user from electromagnetic interference (EMI) noise. The device also features an Enable/Disable Function with an optional pull-up or pull-down resistor to provide user-defined gate drive function.

In summary, the UCC5350SBDR Isolator-Gate Driver is a high-frequency, high-current Gate Driver IC ideal for switching AC and DC loads. The device is designed for high-current driving capability, with a maximum peak current of 3A, with a wide temperature range of -40°C to +105°C. The UCC5350SBDR provides user-defined isolation and offers logic-level safety protected by voltage clamps on the control signal path. The device provides high-frequency switching capability with a maximum switching speed of 25kHz and a minimum pulse width of 50ns.
