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.

NOTES:

Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.

Industrial grade devices shall be tested to subgroups 1 unless otherwise specified.

Space and Military grade devices ("KE & HE" suffix) shall be 100% tested to subgroups 1, 2 and 3.

Subgroups 5 and 6 testing available upon request.

Subgroup 1, 4 TA=TC=+25°C

2, 5 TA=TC=+125°C

3, 6 TA=TC=-40°C for 'KE' and 'HE' SUFFIXES

See UVLO paragraph in the application notes section.

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.

V^BS= +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.
