MIL-PRF-38534 AND 38535 CERTIFIED FACILITY 10 AMP, 100 VOLT RAD HARD MOSFET POWER 3-PHASE MM..SS..KKEENNNNEDEYDYCOCROPR. P. MOTOR DRIVE HYBRID Features : 100V, 10 Amp Capability Ultra Low Thermal Resistance - Junction to Case - 2.5°C/W (Each MOSFET) Self-Contained, Lowside/Highside Drive Circuitry Bootstrap High-Side Supplies Under-Voltage Lockout Capable of Switching Frequencies to 25KHz Isolated Case Allows Direct Heat Sinking Bolt-down Design Allows Superior Heat Dissipation Total Dose Hardened to 300 Krads(Si) (Method 1019.7 Condition A) 4304RH DESCRIPTION: The MSK4304RH 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 ponents 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 patible. Under-voltage lockout prevents the bridge from starting before the supply voltage rises high enough for plete turnon of the output switches. The internal high-side bootstrap power supply derived from the +VB supply pletely eliminates the need for 3 floating independent power supplies.
