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 (200V rating),

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

(22V rating). The drivers feature adjustable dead time

capability, small 30ns propagation delay, and 5.5ns

high-side and low-side matching. These parts also

include internal high-side and low-side LDOs which

ensure a drive voltage of 5V regardless of supply

voltage. The TPS7H60x3-SP drivers all have splitgate

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.
