3 Description

The TPS7H60x3-SP series of radiation-hardnessassured

(RHA) gallium nitride (GaN) field effect

transistor (FET) gate drivers is designed for high

frequency, high efficiency applications. The series

consists of the TPS7H6003-SP (200-V rating),

TPS7H6013-SP (60-V rating), and the TPS7H6023-

SP (22-V rating). The drivers feature adjustable dead

time capability, small 30-ns propagation delay, and

5.5-ns high-side and low-side matching. These parts

also include internal high-side and low-side LDOs

which ensure a drive voltage of 5 V regardless

of supply voltage. The TPS7H60x3-SP drivers all

have split-gate outputs, providing flexibility to adjust

the turn-on and turn-off strength of the outputs

independently.

The TPS7H60x3-SP drivers feature two control input

modes: independent input mode (IIM) and PWM

mode. In IIM each of the outputs is controlled by a

dedicated input. In PWM mode, two complementary

outputs signals are generated from a single input and

the user can adjust the dead time for each edge.

The gate drivers also offer user configurable input

interlock in independent input mode as anti-shoot

through protection. Input interlock disallows turn-on of

both outputs when both inputs are on simultaneously.

The user has the option to enable or disable

this protection in independent input mode, which

allows the driver to be used in a number of

different converter configurations. The drivers can

also be utilized for both half-bridge and dual-low side

converter applications.
