TPS2835DRG4

The TPS2835DRG4 belongs to the family of Power Management Integrated Circuits (PMICs) specifically designed to act as a Gate Driver. It is a single channel advanced current sinking and sourcing Output Driver designed to drive discrete N-channel MOSFETs. It is ideal for various high/low-side, half bridge and three-phase motor drive applications.

The TPS2835DRG4 includes an internal Driver stage comprising of an integrated Gate Driver, a high-performance power operational amplifier, and a small protection circuitry. It is a Gallium Nitride (GaN) device with high resistance to electrostatic discharge (ESD), ultraviolet (UV), and ionizing radiation (Ionizing).

Working Principle of TPS2835DRG4

The TPS2835DRG4 works on the principle of providing a very low voltage (1.6V) gate drive that can quickly drive high output current (20A peak) over a wide range of input voltage (2.5V - 50V). It has high isolation capability and it can drive N-channel MOSFETs with gate charge up to 1nC.

The integrated high-performance power operational amplifier (OPA) provides accurate loop control with fast settling time. The current sinking and sourcing output drivers can be independently adjusted for optimal performance. The SPU and SOURCE pins are both high, so the output drivers can act as high side or low side drivers.

Application Field of TPS2835DRG4

The TPS2835DRG4 is ideal for DC/DC converters, high-side/low-side drivers, automotive powertrains, motor drives and lighting applications. It is specifically designed to drive discrete N-channel MOSFETs. It can be used as a gate driver in applications where fast switching speed is required, such as motor drives and lighting applications.

The TPS2835DRG4 is particularly suitable for automotive applications since it has high resistance to ESD, UV, and ionizing radiation. It is rated for a maximum operating temperature of 150°C, enabling it to work in the harshest of environments.

Conclusion

The TPS2835DRG4 belongs to the PMIC - Gate Driver family. It is a Gallium Nitride (GaN) device with a wide range of input voltage, high output current, and fast settling time. It is ideal for DC/DC converters, high-side/low-side drivers, automotive powertrains, motor drives and lighting applications.
