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)

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 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 compat-

ible. 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 elimi-

nates the need for 3 floating independent power supplies.
