DESCRIPTION The 42144 Full Bridge Power Driver Hybrid is designed for high reliability applications in harsh environment. This compact design offers a full-bridge power driver stage for three-phase brushless DC motor applications. The circuit is electrically isolated from the metal case for ease of mounting in the system. The hybrid package provides two mounting ears for ease of assembly and low thermal resistance path. Each phase contains a high-side gate drive circuit for the P-channel power MOSFET, a series gate resistor for the low-side N-channel power MOSFET, and three Schottky diodes. The high-side gate drive circuit accepts an open-collector signal of the application controller circuit and generates required gate voltage to operate the high-side MOSFET. The low-side gate resistor will prevent any oscillations and minimize ringing. As an option, a Schottky diode in series with the low-side MOSFET insures that braking current will not flow backward through the N-channel MOSFET. Sources of the lowside MOSFETs are terminated individually allowing user to configure the desired current sensing option. Micropac 42144 Full Bridge Power Driver Hybrid employed selected components that are capable to perform in radiation environment with minimum degradation. The hybrid will perform over the full military temperature range of -55C to +125C. It is fabricated using DSCC certified manufacturing processes that are fully in compliance with MIL-PRF-38534. This device is available in a variety of quality levels from COTS to Class K including any custom screening requirements. The basic data sheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF-38534.
