Self-Contained, Lowside/Highside Drive Circuitry
Bootstrap High-Side Supplies
Under-Voltage Lockout

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.

Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.
Pre and post irradiation limits at 25°C, up to 300Krad TID, are identical unless otherwise specified.
When applying power to the device, apply the low voltage followed by the high voltage or alternatively,apply both at the same time.
Do not apply high voltage without low voltage present.
Internal solder reflow temperature is 180°C, do not exceed.

APPLICATION NOTES
MSK 4304RH PIN DESCRIPTIONS
UVLO - The under voltage lockout function of the MSK4304RH
prevents the device from starting before sufficient bias volt-
age is available. The UVLO feature monitors the VDD supply
and holds the outputs low until the voltage level rises above
the threshold during start up. After start up the UVLO circuit
will hold the low side switches off if VDD falls below the thresh-
old but the high side switches will not be controlled by UVLO
after start up.
+VCC - Is the low voltage supply for the lowside driv-
ers. A 0.1 μF ceramic capacitor in parallel with a 10μF
tantalum capacitor is the recommended bypassing from
the +VCC pin to the COM pin.
+VDD - Is the low voltage supply for the input logic to
the hybrid. A 0.1 μF ceramic capacitor in parallel with
a 4.7μF tantalum capacitor is the recommended by-
passing to the COM pin.
MAXIMUM DUTY CYCLE AND HIGH SIDE BIAS - The
MSK4304RH uses three independent bootstrap circuits to
power each of the high side switches. When the switches are
turned on the high side drivers are powered by the charge
in the bootstrap capacitors. The voltage on the bootstrap
capacitors has an initial 1.2V drop and decays at a rate of
approximately 0.5V every 100μS. The voltage can be ap-
proximated by the equation:
+VB - Is the connection used to provide power to the
floating high-side bootstrap supplies in the gate drive
circuitry.
V+ - Is the high voltage positive rail connection to the
tops of the three half bridges. Proper power supply
bypassing must be connected from this pin to the COM
pin for good filtering. This bypassing must be done as
close to the hybrid as possible. +VCC, +VDD and +VB
should be present and stable whenever V+ is present.
VBS = +VB - 1.2V - 5 x TON
TON is the switch on time in mS
VBS is the bootstrap capacitor voltage
VBS should be greater than or equal to 10 volts for maxi-
mum gate drive. If VBS falls too low loss of high side con-
trol my result.
H INA, H INB, H INC - Are active high logic inputs for
signalling the corresponding phase high-side switch to
turn on. The logic inputs are compatible with standard
LSTTL/CMOS outputs. These inputs are clamped to VDD
and COM, they must be limited to less than 10mA if
they are allowed to exceed those limits.
The lowside switches must be activate every cycle or held
active during static operation to provide a return path for
charging the highside bootstrap capacitor and prevent loss
of highside control.
L INA, L INB, L INC - Are active high inputs for signal-
ling the corresponding phase low-side switch to turn
on. The logic inputs are compatible with standard
LSTTL/CMOS outputs. These inputs are clamped to VDD
and COM, they must be limited to less than 10mA if
they are allowed to exceed those limits.
TOTAL DOSE RADIATION TEST
PERFORMANCE
Radiation performance curves for TID testing have been
generated for all radiation testing performed by MS Kennedy.
These curves show performance trends throughout the TID
test process and can be located in the MSK4304RH radiation
test report. The complete radiation test report is available in
the RAD HARD PRODUCTS section on the MSK website.
AØ, BØ, CØ - Are the pins connecting the 3 phase
bridge switch outputs.
AV-, BV-, CV- - Are the connections from the bottoms
of the three half bridges. These pins get connected to
the COM pin. If current sensing is desired they may be
connected to the COM pin through a low value sense
resistor.
http://www.mskennedy.com/store.asp?pid=9951&catid=19680
COM - Is the connection that all hybrid power supply
connections are returned to and bypassed to.

TYPICAL SYSTEM OPERATION
The MSK4304RH is designed to be used with a +28 volt high voltage bus, +15 volt low power bus and +5 volt logic
signals. Proper derating should be applied when designing the MSK4304RH into a system. High frequency layout tech-
niques with ground planes on a printed circuit board is the only method that should be used for circuit construction. This will
prevent pulse jitter caused by excessive noise pickup on the current sense signal or the error amp signal.
Ground planes for the lower power circuitry and the high power circuitry should be kept separate. The connection
between the bottom of the current sense resistor, COM pin and the high power ground, AV-, BV- and CV- pins are
connected at this point. This is a critical path and high currents should not be flowing between the current sense and
COM. Inductance in this path should be kept to a minimum. An RC filter will filter out the current spikes and keep the
detected noise for those circuits down to a minimum.
In the system shown a PWM pulse by pulse current limit scheme controlled by the motor controller is implemented.
When controlling the motor speed by the PWM method, it is required that the low side switches be PWM pulsed to
ensure sufficient bootstrap capacitor charge to power the high side switch drives. The higher the PWM speed the
higher the current load on the drive supply.
