DESCRIPTION:
The MSK 4204RH is a radiation hardened complete H-Bridge microcircuit intended for use in DC brushed motor control
applications or Class D switchmode amplification in space or other severe operating environments. The internal compo-
nents have been selected to provide total dose up to 300K RAD for military and space applications. All of the drive/control
circuitry for the lowside and highside switches are internal to the device. The PWM circuitry is internal as well, leaving the
user to only provide an analog signal for the motor speed/direction, or audio signal for switchmode audio amplification. The
MSK 4204RH is packaged in a space efficient isolated power package, available in three lead form configurations that can
be directly connected to a heatsink.

+VCC - Is the low voltage supply for powering internal
logic and drivers for the lowside and highside MOSFETS.
The supplies for the highside drivers are derived from this
voltage. Optimum operation occurs with V
CC
set at 15V.
AV+, BV+ - Are the high voltage H-bridge supply pins.
The MOSFETS obtain the drive current from these supply
pins. The voltage is limited by the drive IC. The MOSFETS
are rated at 100 volts. Proper by-passing to GND with
sufficient capacitance to suppress any voltage transients,
and ensure removal of any drooping during switching,
should be done as close to the pins on the hybrid as pos-
sible.
A - Are the output pins for one half of the bridge. In-
creasing the input voltage causes increasing duty cycles
at this output.
B - Are the output pins for the other half of the bridge.
Decreasing the input voltage causes increasing duty cycles
at this output.
AV- - Are the connections for the bottom of the A half
bridge. This can have a sense resistor connection to the
V+ return ground for current limit sensing, or can be con-
nected directly to ground. The maximum voltage on these
pins is 5 volts with respect to GND.
BV- - Are the connections for the bottom of the B half
bridge. This can have a sense resistor connection to the
V+ return ground for current limit sensing, or can be con-
nected directly to ground. The maximum voltage on these
pins is 5 volts with respect to GND.
INPUT - Is an analog input for controlling the PWM pulse
width of the bridge. A voltage higher than 7.5V will pro-
duce greater than 50% duty cycle pulses out of OUTPUT
A. A voltage lower than 7.5V will produce greater than
50% duty cycle pulses out of OUTPUT B.
SHUTDOWN - Is the connection for disabling all 4 output
switches. SHUTDOWN high overrides all other inputs.
When taken low, everything functions normally. An inter-
nal pullup to Vcc will keep SHUTDOWN high if left uncon-
nected. This pin should be grounded if not used.
GND - Is the return connection for the input logic and
Vcc.

This is a diagram of a typical application of the MSK 4204RH. The design Vcc voltage is +15 volts and should have a good low
ESR bypass capacitor such as a tantalum. The analog input can be an analog speed control voltage from a potentiometer, other
analog circuitry or by microprocessor and a D/A converter. This analog input gets pulled by the current control circuitry in the proper
direction to reduce the current flow in the bridge if it gets too high. The gain of the current control amplifier will have to be set to
obtain the proper amount of current limiting required by the system.
Current sensing is done in this case by a 0.1 ohm sense resistor to sense current from both legs of the bridge separately. It is
important to make the high current traces as big as possible to keep inductance down. The storage capacitor connected to the V+
and the hybrid should be large enough to provide the high energy pulse without the voltage sagging too far. A low ESR ceramic
capacitor or large polypropylene capacitor will be required. Mount capacitor as close to hybrid as possible. The connection between
GND and the V+ return should not be carrying any motor current. The sense resistor signal is common mode filtered as necessary
to feed the limiting circuitry for the microprocessor. This application will allow full four quadrant torque control for a closed loop
servo system.
A snubber network is usually required, due to the inductance in the power loop. It is important to design the snubber network to
suppress any positive spikes above 100V and negative spikes below -4V with respect to GROUND.
