PMIC (Power Management Integrated Circuit) - Gate Drivers are essential components in any power-related circuit. The UCC27210DPRR from Texas Instruments is a TTL compatible, 6-channel high-side MOSFET-based gate driver designed to drive N-channel MOSFETs, IGBTs, and other devices requiring high-side gate drive. Its flexible power supply options (12V-18V rated) and compact design make it ideal for a wide range of applications, including in mobile phones and tablet PCs.

The UCC27210DPRR is suitably sized for integration into 5-volt, 3.3-volt, and even 12-volt systems. It is rated for up to 18 volts of V+. Its low-collapse threshold (Vth) of 1.8 volts makes it suitable for driving both low- and high-side switches. Additionally, It features an adjustable dead time control to ensure that the outputs remain in an off-state at power-up, as well as an Under-Voltage Lockout (UVLO) feature that prevents the drivers from being turned on when the supply voltage is below a predetermined level.

Its integrated temperature sense circuit ensures robust, reliable operation within its rated power supply voltage and temperature range. The UCC27210DPRR also comes with specially designed heat sinks for those applications where heat dissipation is a limiting factor. It also provides three levels of enable/disable protection for internal MOSFETs and an output stage amplifier.

The UCC27210DPRR works by sinking current from the load side, to charges a capacitive layer (Clayer) between the top isolation layer and the substrate (Ts). When a logic high is applied to the output, the charges at Clayer is forced to move towards the top isolation layer, creating a conductive channel between the source and drain. This channel acts like an switch, allowing the current to flow between the source and the drain and thus powering the connected load.

Due to its wide Vcc range, small package size, and low-collapse threshold, the UCC27210DPRR is suitable for applications such as automotive and industrial motor drive systems, AC/DC and DC/DC converters, DC/ AC inverters, UPS systems and power supplies, as well as high-current/high-voltage DC-DC converters.

In conclusion, the UCC27210DPRR is a high-side gate driver with integrated temperature protection and adjustable dead time, designed for switching N-channel MOSFETs, IGBTs, and other devices requiring high-side gate drive. Its compact size, low-collapse threshold, and wide power supply range make it especially suitable for applications requiring robust, reliable power management.
