DESCRIPTION:
The MSK 4304RH is a radiation hardened 10 Amp, 3 Phase Bridge Power Motor Drive Hybrid with a 100 volt
maximum rating on the output switches. The internal components have been selected to provide total dose tolerance
for military and space applications. The output switches are MOSFETs. This new power motor drive hybrid is 5.0 volt
input logic compatible. Under-voltage lockout prevents the bridge from starting before the supply voltage rises high
enough for complete turn-on of the output switches. The internal high-side bootstrap power supply derived from the
+VB supply completely eliminates the need for 3 floating independent power supplies.
