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 low-
side 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.
