The TPS7H60x3-SP series of
radiation-hardness-assured (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 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.
