Abstract:
In a switching converter having an inductive load, a current may flow through the body diode of a transistor even though the gate of the transistor is being controlled to keep the transistor off. Then when the other transistor of the switch leg is turned on, a reverse recovery current flows in the reverse direction through the body diode. To reduce switching losses associated with such current flows, a gate driver integrated circuit detects when current flow through the body diode rises above a threshold current. The gate driver integrated circuit then controls the transistor to turn on. Then when the other transistor of the switch leg is made to turn on, the gate driver first turns the transistor off. When the gate-to-source voltage of the turning off transistor drops below a threshold voltage, then the gate driver integrated circuit allows and controls the other transistor to turn on.

Claim (Index 1):
A gate driver integrated circuit comprising:\n a high-side driver digital control signal input terminal; a high-side driver output terminal; a high-side gate driver circuit that outputs a high-side gate driver output signal onto the high-side driver output terminal; a low-side driver digital control signal input terminal; a low-side driver output terminal; a low-side gate driver circuit that outputs a low-side gate driver output signal onto the low-side driver output terminal; a high-side current sense input terminal; a high-side voltage sense input terminal; a low-side current sense input terminal; a low-side voltage sense input terminal; a high-side driver logic circuit that supplies a control signal to the high-side gate driver circuit and that receives a high-side driver digital control signal from the high-side driver digital control signal input terminal; a low-side driver logic circuit that supplies a control signal to the low-side gate driver circuit and that receives a low-side driver digital control signal from the low-side driver digital control signal input terminal; a high-side current sense circuit that receives a signal from the high-side current sense input terminal and that supplies a signal to the high-side driver logic circuit; a high-side voltage sense circuit that receives a signal from the high-side voltage sense input terminal and that supplies a signal to the low-side driver logic circuit; a low-side current sense circuit that receives a signal from the low-side current sense input terminal and that supplies a signal to the low-side driver logic circuit; and a low-side voltage sense circuit that receives a signal from the low-side voltage sense input terminal and that supplies a signal to the high-side driver logic circuit.
