. y9 K: m8 f- r# W8 qThe ZCC6501 consists of an oscillator followed by a gate drive circuit that provides the complementary output
signals to drive the ground referenced N-channel power switches. The internal logic ensures break-before-make
action between the two switches.
The ZCC6501is available in a small SOT23-5 package, and is specified for operation at temperatures from –40°C
