A PMIC – Gate Driver is an integrated circuit (IC) integrated in an off-chip gate drive where it controls the interface between an external control voltage and an output stage. The main function of a PMIC consists in driving power devices, such as binary-switched devices or bidirectional axial windability devices. It also regulates the electrical parameters of the output stage, such as output voltage and current.

The UCC27710DR is a PMIC TTL logic-to-gate driver example; it offers robust and high-performance technical characteristics. This IC is widely used in different applications, more specifically in home appliances, industrial control, power electronics, medical and consumer products.

The device accepts 5V and 3.3V TTL logic, and it integrates a front-end circuit that provides internal circuit protection and brings common-mode transient immunity (CMTI). It has up to 30mA sink and 30mA source drive capabilities, with a 600 ns speed to the output stage.

The UCC27710DR comes with a built-in 1.1 microsecond maximum propagation delay time. This high-speed response from the input to the output operation makes the IC suitable for faster operations in power electronics design. The configuration also includes a wide operating temperature range from -40°C to 85°C.

The UCC27710DR is a PMIC TTL logic-to-gate driver that includes a level-shifting feature for isolation and for supplying energy to the load. It has an integrated power MOSFET with a built-in voltage regulator, a N-channel MOSFET driver, and two status LEDs that provide a visual indication of the output status.

The UCC27710DR’s working principle is based on its internal logic circuit, controlling four logic inputs and a logic output. When the logic input signals the logic output, the internal logic circuit generates a voltage across the appropriate MOSFET. This voltage is then shifted over the levels that the external device needs to drive its output stage.

In summary, the UCC27710DR is an example of a PMIC TTL logic-to-gate driver which is suitable for a wide range of applications, such as power electronics design and home appliances. It has an internal logic circuit and a level-shifting feature that provides an efficient voltage supply to the output stage. This IC provides common-mode transient immunity, high-speed response and a wide operating temperature range, resulting in a reliable and robust system solution.
