DESCRIPTION:
The MSK 4900 is a complete isolated half bridge gate driver hybrid capable of working to 600V channel isolation and 8
amps peak turn-on and turn-off current. Housed in an isolated, convenient bolt-down hermetic package, the MSK 4900
houses the entire isolated DC-DC converter circuitry and opto-isolators for logic signals. The input logic prevents simulta-
neous conduction by locking out both high side and low side drives in case both inputs are asserted ON at the same time.
Each gate drive is capable of sourcing and sinking up to 8 amps peak current. The turn-on and turn-off pins are separate to
allow separate gate current control. Upon detection of a de-saturation condition, a FAULT is presented and the transistor is
shutdown by a separate controlled shutdown pin. There are two modes available for clearing a FAULT. They are selected at
device power up. MANUAL FAULT CLEAR MODE requires the FAULT to be cleared by the system before normal operation
will begin again. AUTOMATIC FAULT CLEAR MODE clears the FAULT a short period after shutdown at which time normal
operation commences. The MSK 4900 has good thermal conductivity due to an isolated substrate/package design that
allows direct heat sinking of the device without insulators.
