Texas Instruments is expanding its range of mosfet drivers with two output gate, 120V boot, high- and low-side drivers which provide up to 4A output current, while handling -10V of direct current (VDC) immunity on the driver inputs.

The UCC27210 and UCC27211 drivers support multiple high-frequency half-bridge and full-bridge power topologies with an 18ns propagation delay.

The 0.9ohm pull-up and pull-down resistance is designed minimise switching loss as the mosfets transitions. Inputs support -10V of direct current, and allows direct interface to gate-driver transformers without the need for rectification diodes.

TI has also introduced a fast 5A dual-channel low-side driver for secondary-side synchronous rectifier mosfets and IGBT power switches.

The UCC27524 delivers low pulse distortion and high efficiency with a 12ns propagation delay, 6ns rise time with 1ns output delay matching.

The driver, which supports 4.5-V to 18-V operating voltages.
